Vacuum pump for coal industry
Coalbed methane is generally adsorbed on the coal seam, which has to go through three production processes: drainage, depressurization and gas production. The vacuum pumps used in coal mines are from SZ series of Soviet Union to SK Series independently developed by our country, and then to the leading position today. 2be series water ring vacuum pumps adopt the most advanced foreign technology, and each change is toward the direction of energy saving and reliability. For example, the SZ-4 vacuum pump in the 1960s and 1970s had a maximum gas volume of 1700m3 / h, and its efficiency was only 20% - 30%. Sk-85a, the largest in the 1980s, had a gas volume of 5100m3 / h and an efficiency of 30% - 40%. However, the 2BE3 series water ring vacuum pump / compressor with foreign advanced technology, developed and produced through joint venture and cooperation, has a gas volume of 60000m3 / h, an efficiency of 45% - 60% or more, and operates more effectively Reliable.
Safety, complete set, automation and high reliability are the basic requirements for vacuum pump in coal industry. Traditionally, vacuum pumps are mainly used by equipment manufacturers, such as pre separators, anti backfire devices, gas separators, electric control, sensors, instruments, etc. are configured by the coal mining enterprises themselves. This not only reflects the low degree of complete set, but also leads to the low efficiency of main equipment due to the incongruity of configuration, and even the equipment can not work normally due to professional differences Make.
Therefore, complete equipment is the development direction of vacuum equipment in coal industry. In the coal industry, the vacuum pump, whether used for gas drainage, transportation, coal washing, chemical industry, drying and well production, has a unique use environment. However, China's coal mines are widely distributed, with different climatic and geographical conditions. In view of these particularities, providing personalized vacuum equipment is also the direction of product development in vacuum equipment manufacturing industry. Vacuum industry manufacturers are committed to the research and development of safety, energy saving, environmental protection, chemical and other equipment in China's coal industry, and have developed a set of mechanical, electrical and instrument integrated vacuum unit, equipped with complete steam water separator, circulating heat exchanger, online measurement and control instrument, automatic control system, valve components, etc.

Various vacuum valves
Vacuum valves mainly include vacuum ball valve, vacuum butterfly valve, vacuum diaphragm valve, vacuum gate valve and vacuum stop valve. The types of vacuum valves are different, and the applicable occasions are also different. The following describes the characteristics and common areas of valves of different types such as gate valve, globe valve, butterfly valve and ball valve. Finally, according to the different use requirements, how to select the valve, such as according to the prevention of backflow of medium, according to the adjustment of medium parameters to select the valve.
The vacuum gate valve is used as a cut-off medium. When it is fully open, the whole flow is straight through, and the pressure loss of medium operation is the minimum. Gate valve is usually suitable for the condition that it is not necessary to open and close frequently and keep the gate fully open or closed. Not suitable for regulating or throttling. For the high-speed flow medium, when the gate is partially opened, it can cause the gate vibration, and the vibration may damage the sealing surface of the gate and the valve seat, and throttling will make the gate suffer from the erosion of the medium.
From the structural form, the main difference is the form of sealing elements used. According to the form of sealing elements, gate valves are often divided into several types, such as wedge gate valve, parallel gate valve, parallel double gate valve, wedge double gate valve, etc. The most common forms are wedge gate valve and parallel gate valve.

Installation and operation steps of chemical centrifugal pump
Chemical centrifugal pump refers to the centrifugal pump used in the chemical field. Compared with other types of pumps, chemical centrifugal pump has the advantages of simple structure, not easy to wear, stable operation, low noise, uniform water outlet, convenient adjustment and high efficiency, so chemical centrifugal pump has been widely used.
The key to the installation technology of chemical centrifugal pump is to determine the installation height (i.e. suction head) of chemical centrifugal pump. This height refers to the vertical distance between the water surface of the water source and the center line of the impeller of the chemical centrifugal pump. It can not be confused with the allowable vacuum height. The allowable suction vacuum height on the chemical centrifugal pump product manual or nameplate refers to the vacuum value on the water inlet section of the chemical centrifugal pump, and is measured by test under 1 standard atmospheric pressure and water temperature of 20 ℃ Yes. It does not take into account the water flow condition after the matching of the suction pipe. The installation height of chemical centrifugal pump should be allowed to absorb the vacuum height, after deducting the loss of suction pipe head, the remaining part of the value, it should overcome the actual terrain suction height. The installation height of chemical centrifugal pump should not exceed the calculated value, otherwise, the chemical centrifugal pump will not be able to pump water.
The working principle of chemical centrifugal pump is that when the pump is full of water, the impeller rotates to produce centrifugal force. The water in the impeller channel is thrown out and flows into the pump shell under the action of centrifugal force, so the pressure at the center of the impeller decreases, which is lower than the pressure in the water inlet pipe, and the water flows into the impeller from the suction tank under the effect of this pressure difference. In this way, the pump can continuously absorb water and supply water continuously.

The main features of the low vacuum unit are
high working pressure and large exhaust volume, but the pumping speed is lower
than that of the high vacuum unit. It is mostly used in rough pumping of vacuum
chamber and vacuum conveying, vacuum impregnation, vacuum filtration, vacuum
drying, vacuum degassing (molten steel treatment) and other devices with large
exhaust volume and high working pressure.
The main pumps of low-vacuum pumping units are commonly used reciprocating vacuum pumps, oil-sealed mechanical pumps, dry mechanical pumps, water jet pumps, water vapor jet pumps, water ring pumps, molecular sieve adsorption pumps, wet roots pumps and other straight-out atmospheric vacuum pumps. To use the low-vacuum extraction unit, the necessary dust collector, water-gas separator, oil-water separator, dry bath trap and other components must be equipped according to the cleaned degree of the exhausted gas, humidity or other special requirements.

Main uses of water jet pump
① It is used in vacuum distillation, concentration, dehydration, decolorization, drying, crystallization, filtration, degassing, material transportation, tail gas and dust absorption in chemical and pharmaceutical industries.
② It is applied to spray condensing secondary steam. In some processes, a large amount of secondary steam will be produced and a small amount of non condensable gas needs to be discharged to maintain normal production. This kind of water jet pump is also called water jet condenser, which takes condensation as the main and exhaust as the auxiliary.
③ It is applied to vapor-liquid mass transfer and absorption. The liquid flowing out at high speed meets the ejected gas. The entrainment process of air flow by jet is also the process of vapor-liquid two-phase mixing. Due to the large contact surface between gas and liquid in water jet pump, high-speed jet has great speed, which greatly strengthens the speed of mass exchange in absorption and mass transfer, and accelerates chemical reaction or material transfer process. Therefore, water jet pump has the function of both reactor and pump. It is used as absorption and mass transfer equipment in many occasions
④ In many large chemical plants and chemical fertilizer plants, the steam or hot water with certain energy is often discharged, resulting in energy waste. Water jet pump is used to inject low-energy fluid with less jars of high-energy fluid, so as to increase the energy site of the fluid, and then used in the production process.

Vacuum pump in oil refining and petrochemical production
Vacuum pump is
a kind of conveying machinery that draws air from negative pressure and exhausts
at atmospheric pressure. Its purpose is to create and maintain the vacuum
required by the process system. The vacuum pumps commonly used in oil refining
and petrochemical production include reciprocating vacuum pump, water ring
vacuum pump and jet vacuum pump.
The structure and working principle of reciprocating vacuum pump are basically the same as that of reciprocating compressor. The pressure difference between inside and outside the cylinder is very small, but its compression ratio is very large (for example, for 95% vacuum degree, the compression ratio is about 20). Therefore, the suction and discharge valves of the reciprocating vacuum pump must be light and flexible, easy to open and close; the volume of the rest gaps must be very small. At the same time, in order to reduce the adverse effect of the residual gas in the clearance on the pumping rate of the vacuum pump, the inner wall of the two ends of the cylinder of the vacuum pump is often provided with a balance airway connecting the two sides of the piston.
At the end of exhaust, the balance port can make the clearance communicate with the other side of the piston for a short time, so that the residual gas in the clearance can flow to the other side of the piston through the balance airway, so as to reduce the pressure of the gas in the clearance, so as to improve the suction efficiency, that is, to increase the volume coefficient. The limit vacuum produced by reciprocating vacuum pump can reach about 2KPa (absolute pressure). The gas discharged by reciprocating vacuum pump should not contain liquid. If the gas contains a large amount of steam, the condensable gas must be removed (generally condensed) before entering the vacuum pump, that is, reciprocating vacuum pump belongs to dry vacuum pump.

roots rotor vacuum unit performance characteristics
There are many types
of vacuum units, mainly related to the type of main pump. Roots rotary vane
vacuum unit is composed of roots pump as the main pump and single or double
stage rotary vane vacuum pump as the front pump
Roots rotary vane vacuum unit is a low and high vacuum obtaining equipment with roots vacuum pump as the main pumping pump and single-stage or double-stage rotary vane pump as the front stage pump. The whole unit is arranged on a frame, equipped with pipeline, valve and electrical operation control box, and also equipped with cooling water pipe system. The unit is compact in structure and convenient in use, with high vacuum degree, low noise and sustainable work.
The ratio of the nominal pumping speed of each pump of roots rotary vane vacuum unit is generally between 41 and 101. In order to prevent the front rotary vane vacuum pump from shutting down and returning oil, an electromagnetic vent valve is installed on the front pipeline, whose action is linked with the motor of the front rotary vane vacuum pump, so as to ensure the normal and efficient operation of the pump.
In order to improve the pumping performance of the vacuum unit, reach a higher limit vacuum, improve the pumping speed characteristics at low inlet pressure and use a smaller specification of the front pole pump for large vacuum units, roots vane vacuum units can also be used in series with two-stage roots vacuum pump to form a three-stage unit according to customer requirements.

Advantages of vacuum pump planning
Vacuum pump is a kind of positive displacement pump. The size of the pump body determines the concave convex power of vacuum pump. At present, the round pump body is widely used in vacuum pump at home and abroad. The advantage of such planning lies in the convenience of processing and installation; therefore, the power of vacuum pump is not high. The main reason is that the impeller of vacuum pump needs more centrifugal force to make the sealing liquid separate the inlet and exhaust of vacuum pump.
The sealing liquid in the vacuum pump can transfer energy and seal effect in the vacuum pump, but the vacuum pump can only reach the planned volume as far as possible because of the structural constraints in the suction and discharge cavity, while the traditional vacuum pump body is the welding pump body, with smooth steel plate surface, and the straight impact of the sealing liquid on the smooth surface will show a straight-line repeated turn back, and then secondary noise will occur, which is smooth The surface of the vacuum pump has no ability to absorb noise.
Low noise vacuum pump features: compact structure, small floor area. Because the gas is compressed in the pump, the power consumption is low. Because there is no oil in the vacuum chamber, the dust will not stay in the pump chamber, but will be discharged out of the pump with the gas from the exhaust port. Moreover, it can deal with the problems of oil emulsification, frequent replacement of working fluid, frequent protection and maintenance, and save the use cost.

Working principle of vacuum pump
The vacuum pump can be defined as the device or configuration that controls the machine, physics, chemistry or physical chemistry to pump air to the evacuated container. With the development of vacuum application, there are many kinds of vacuum pumps, whose pumping speed is from 0.5 liter per second to hundreds of thousands or millions of liters per second. The limit pressure (limit vacuum) ranges from coarse vacuum to ultra-high vacuum above 10-12 PA. Due to the wide range of incident pressure involved in the vacuum application part, any kind of vacuum pump can be completely applied to the whole incident pressure range, only according to different incident pressure range and different incident requirements, different types of vacuum pump can be used. In order to make use of the convenience and the necessity of various vacuum processes, various vacuum pumps are occasionally combined according to their properties and requirements, and they are applied in the unit type, i.e. vacuum unit.
The vacuum pump can be used alone, and can also be used as the pre pump of booster pump, diffusion pump, molecular pump, maintenance pump and titanium pump. It can be used in the manufacture of electric vacuum vessel, vacuum welding, printing, plastic absorption, refrigeration equipment maintenance, instrument equipment matching and laboratory, etc.
The two rotors of vacuum pump are operated synchronously by a pair of high precision gears. The driving shaft is connected with the motor through the coupling. There are mainly two types of transmission structure arrangement: one is that the motor and gear are placed on the same side of the rotor as shown in the figure. Driven rotor is directly driven by the motor end gear, so that the torsional deformation of the active rotor shaft is small, the gap between the two rotors will not be changed due to the large torsional deformation of the active shaft, so that the gap between the rotors is even in the operation process. The major disadvantages of this transmission mode are: A. There are three bearings on the driving shaft, which increases the difficulty of processing and assembly of the pump, and the disassembly and adjustment of the gear is also inconvenient; B. the overall structure is uneven, and the center of gravity of the pump is inclined to the side of the motor and gearbox.

Leakage rate detection of water ring vacuum pump
Leakage rate detection of water ring vacuum pump
With the development of society, vacuum pump has been widely used, especially water ring vacuum pump is a typical vacuum pump. In order to use it better, we often need to detect the leakage rate, which is mainly divided into internal leakage and external leakage detection. The internal leakage is more complex. Let's have a detailed understanding.
1. The internal leakage of water ring vacuum pump mostly occurs on the equipment with water-cooled jacket. No doubt was found through checking the external leakage, but there are the following phenomena: the pumping speed of mechanical pump is obviously low, the indicated value of vacuum gauge is low, the mechanical pump oil is quickly emulsified, and the iron-based parts in vacuum chamber are obviously rusted. If the above conditions are met, internal leakage can be basically determined. Clean the inner wall first, and then pass cooling water to see if there is any wet point. The wet point is the leakage point.
2. Small leakage and micro leakage are difficult to check. The commonly used method is to use the ionization tube sensitive to some gases in high vacuum state to detect leakage, such as acetone or ethanol. Use a medical syringe to spray acetone or ethanol to the suspicious place. When it is sprayed to the leakage point, the pointer of the ionization meter will swing obviously. In this way, we must be patient, wait until the indicator value of the ionization meter is stable, that is, the pumping capacity and leakage rate of the water ring vacuum pump are balanced, and then spray again, try to repeat several times to confirm the leakage point.
3. For larger leakage point, flame method can be used. Based on the principle that air flow can make the flame deviate, vacuum first. For example, use candle or lighter to gradually search around the suspicious point, and it will be found that the flame deviates to the leakage point, then the leakage point can be found.

Water ring vacuum pump in mine
Water ring vacuum pump in mine
Water ring vacuum pump system is usually composed of vacuum pump, coupling, air-water separator and pipeline. With the help of the rotating impeller, the water ring vacuum pump makes water or other working liquid form a rotating liquid ring, through which the gas pumped is compressed and discharged to obtain vacuum.
The air in the suction pipe is pumped out by the water ring vacuum pump, so as to form a vacuum in the closed suction pipe and the pump body and generate a negative pressure. Depending on the atmospheric pressure, the water is pumped from the suction pipe to the pump body. The direction of water injection is from bottom to top. With this way of water injection, the vacuum degree of the water suction pipe and the pump body is stable, and the water pressure is put into the water suction pipe and the pump body by the atmospheric pressure, which overcomes the self weight of the water in the water suction pipe and can meet the vacuum degree requirements of the main drainage pump during drainage.

Anticorrosion performance of water ring vacuum pump
Anticorrosion performance of water ring vacuum pump
Water ring vacuum pump is widely used with complete specifications and strong adaptability. Ordinary material pumps can meet most of the use requirements, but due to the different nature of materials, some working conditions have higher requirements on the anti-corrosion performance of pumps, so the pumps need to be made of anti-corrosion materials, let's understand this aspect:
According to the vacuum degree and corrosiveness of the pumped gas, the material configuration of water ring pump can be divided into three categories.
According to different anti-corrosion requirements, the flow passage parts of water ring pump can be made of stainless steel of corresponding brand, or the user can select materials according to needs. When the pump body is lined with rubber, the corrosion resistance of the pump body can be improved. When the flow passage parts are sprayed with special materials, the smooth spraying surface can avoid the retention of impurities and improve the hydraulic efficiency of the water ring pump.
The main parts of the water ring vacuum pump can meet the strict anti-corrosion requirements after anti-corrosion treatment or manufacturing with anti-corrosion materials. In addition to the above configurations, our company can also provide comprehensive and complete solutions according to the requirements of various working conditions of users.

Startup mode of Roots vacuum pump
Startup mode of Roots vacuum pump
Roots pump can not be started and used, which is basically known to the staff who often operate the equipment, but some novices always make this mistake. Therefore, today's editor will talk about the operation knowledge in this field, so as to avoid this kind of error when you first contact the equipment.
1. Roots pump can not be used alone. It usually needs to be equipped with a front stage pump, which is mainly used to improve the pumping speed, so it is also called a mechanical booster pump.
2. The roots pump can only be started when the previous pump reaches the allowable starting pressure. If it is started directly or fails to meet the air pressure requirements, the pump will be overloaded and the motor will be burned. Generally, the starting pressure is about 1.5 times of its differential pressure. For example, if the pressure difference of zj150 is 6000pa, the starting pressure is when the water ring pump pumps the system pressure to 90mbar.
3. If the front stage pump is a water ring pump, in order to prevent the circulating water of the water ring pump from flowing back into the oil tank, a check valve must be installed between the frontal water ring pump.
4. Roots pump can only work through the unit.
Therefore, before the roots pump is installed and ready for formal start-up, it must be checked first to ensure that all parts are installed correctly and auxiliary parts are complete, so as to carry out trial operation. After ensuring that there is no operation problem, it can be formally started for use, which is the correct and stable approach.

Pipeline Installation of Liquid Ring Vacuum Pump
What problems should we pay attention to when installing the pipeline of the liquid ring vacuum pump?
(1) All pipelines of liquid ring vacuum pump should be checked for sealing before installation, and the internal iron chips, rust and oil stains should be cleaned up.
(2) Reliable sealing gaskets, especially vacuum pipelines, should be used at the flange joints of pipelines, and the sealing requirements should be stricter.
(3) The intake pipeline is connected with the inlet of the liquid ring vacuum pump, and the exhaust pipeline is connected with the outlet of the separator water tank.
(4) Gate valves should be installed on the intake pipe near the liquid ring vacuum pump to prevent the water in the pump from flowing down to the intake pipe under the pressure of the exhaust pipe when the pump stops.

How to solve the rusting of water ring vacuum pump
How to solve the rusting of water ring vacuum pump?
If scale can be soaked in oxalic acid, hydrochloric acid can also be used, but to control the concentration of hydrochloric acid, too high acidity will corrode the pump, if it is water rust, you can use oil lubrication, or use pipe pliers to move. Of course, hydrochloric acid can not be released.
When the motor is fixed, it can pour some loosening fluid on the bearing, and after loosening, it can be poured with lubricating oil. This should be the result of poor maintenance in peacetime. When not in use for a long time, it is necessary to release the water and store the desiccant in the pump. Which water you can add a little rust inhibitor, it will be better.
The rust in the vacuum pump chamber is mainly caused by the high water temperature of the water ring pump. When the temperature is high, there will be scales. If there is more scales, there will be no clearance in the pump chamber, which will cause the vacuum pump to remain motionless. The circulating water should control the water temperature.
At present, there is no better solution, which is a disadvantage. Next, water should be released when it is no longer used. If you can add some oil to lubricate the impeller and pump chamber, it will run when you use the pump next time.

Operation Conditions of Vacuum Pumps
I believe you are not unfamiliar with the vacuum pump, and have a lot of knowledge about it. Have you ever known about the operating conditions of the vacuum pump? If not, let's take a look at the following article.
Because vacuum pumps have selective pumping, sometimes one pump can not meet the requirements of pumping. It needs several pumps to be combined to complement each other in order to meet the requirements of pumping. For example, the titanium sublimation pump has a high pumping speed for hydrogen, but it can not pump helium, while the tripolar sputtering ion pump (or the bipolar asymmetric cathode sputtering ion pump) has a certain pumping speed for argon. If the two pumps are combined, the vacuum device will get a better vacuum degree.
In addition, some vacuum pumps can not work at atmospheric pressure, need pre-vacuum; some vacuum pumps outlet pressure is lower than atmospheric pressure, need the front pump, so they need to be combined to use.

Antisepsis of Water Ring Vacuum Pump
Water ring vacuum pump, maybe we haven't seen, but I believe you all know it, the next edition will take this opportunity to introduce you to the anti-corrosion work of water ring vacuum pump.
In the maintenance of water ring vacuum pumps, there is a skill that can not be ignored, that is, corrosion protection. As a form of metal corrosion, we all know that there are two kinds of metal corrosion, one is comprehensive corrosion, the other is general corrosion. No matter which kind of corrosion, it will not have very good results. In the future, we can prevent this kind of corrosion from causing unnecessary damage, but we can use polymer composite repair to implement organic coating corrosion protection on the surface of water ring vacuum pump, which is one of the most effective anti-corrosion measures at present.
Surface sticking protection of water ring vacuum pump can be widely used in repairing and pre-protecting coatings of abrasion, cavitation and corrosion parts.

Axle-holding problem of water ring vacuum pump
The water ring vacuum pump is suitable for the use of mines with small drainage volume and high negative pressure. Many problems will occur under the condition of long-term non-rest work. Among them, the special one is the axle-holding. Here we introduce the axle-holding problem of the equipment.
1. The problem of holding axle of water ring vacuum pump is mainly based on bearing assembly. The reasons are as follows:
2. The quality of lubricating oil is also related to the occurrence of this situation. If the overall vibration of the pump is too large, it is also the cause.
3. There are differences in the quality of bearings, or wear and aging caused by long-term operation.
4. In the process of assembling, the requirements of bearing positioning and design are quite different, the positioning is inaccurate, and the selection of components is unreasonable.
Above is the reason why the water ring vacuum pump holds the axle. From this we can know that the reason is the quality difference and the wear and tear aging caused by long-term work without rest. It is very important for the equipment to stop and rest. We all need to rest, not to mention the machine. Regular rest is conducive to better operation of the equipment.
