Development of Roots vacuum pump performance

When roots vacuum pump works, rotor and rotor, rotor and pump body are not in contact with each other, so there is no direct wear. However, due to the small clearance (generally 0.10 ~ 0.25 mm), the transmission gear is worn after long-term operation. When the backlash is greater than the minimum clearance between rotors, it will collide and cause failure. At this time, the gear should be replaced. Through the performance of the practical application value ability of Roots vacuum pump, enhance the continuous promotion of the actual development ability of the product, further reflect the development advantage of the product strength with the reliable advantage level, expand the overall improvement of the practical performance, promote the improvement of the actual performance of all aspects of the product, improve the driving force of the practical performance of the product, and make it full use of the value strength of the overall development We should speed up the exertion of the advantage level of its product application, make use of its reliable practical performance, and enhance the embodiment of its product application level. 

At the same time, we should also speed up the improvement of the product advantage level of Roots vacuum pump, expand the exertion of the product application strength and the overall performance level, expand the continuous improvement of the overall application strength of the product, fully reflect the exertion of the product value strength, and further enhance the actual application advantage level with reliable product performance.

Operation characteristics of oil-free vacuum pump

The oil-free vacuum pump is the operation cavity of the pump, there is no medium to recover the original gas. There are many other categories of products that are loved by many professions. In the purchase of oil-free vacuum pump time must not be greedy cheap to choose a low price, but should be on-site investigation, to choose a suitable for their own. 

The working principle of oil-free vacuum pump is the same as that of general positive displacement pump. It is composed of stator, rotor, rotating plate, cylinder block, motor and other primary parts. When the rotor rotates at high speed, the four radial sliding blades in the rotor slot will divide the pump chamber into four operating rooms, because of the centrifugal force effect, the vane is close to the cylinder wall.

Separate the inlet and outlet of the stator, operate in a circular manner, change the volume, discharge the inhaled gas from the exhaust port, and then reach the purpose of air extraction. How does the oil vapor discharged from the oil-free vacuum pump affect the environment. If the environment does not allow pollution, can choose oil-free oil-free vacuum pump, perhaps the oil vapor discharged to the outdoor. Correctly combine the oil-free vacuum pump.

Because the oil-free vacuum pump has selective pumping, sometimes one kind of pump can not meet the pumping requirements, and several pumps should be combined to make up for each other to meet the pumping requirements. If the titanium pump has a high pumping speed for hydrogen, but can not pump helium, and the tripolar sputtering ion pump (or bipolar asymmetric cathode sputtering ion pump) has a certain pumping speed for argon, the combination of the two will make the vacuum equipment get better vacuum degree.

difference between medical vacuum pump and industrial vacuum pump

Medical vacuum system is an important part of hospital design and construction. Its main application principle is vacuum suction. In the construction of medical vacuum pump system, the choice of medical vacuum pump is different from that of general industrial vacuum pump. These differences mainly involve three aspects. 

First, the vacuum in industrial production tends to be higher, while the vacuum in medical vacuum is lower. Vacuum is widely used in industrial production and has a long span. The vacuum degree of many vacuum applications is usually less than 1 HPA; while the medical vacuum cleaner is mainly used for dust collection, and generally does not need too high vacuum degree, and the absolute pressure is mostly between 13 ~ 60kpa, which is much lower than that of industrial vacuum pump. Therefore, it is necessary to distinguish when choosing medical vacuum pump.

The second point is that the continuity of the vacuum chamber is different. Many vacuum chambers in industrial vacuum applications are used intermittently, which means that the operation of vacuum pump is mostly intermittent; the medical vacuum system is used continuously and simultaneously with different gas points.

Third, the purpose of vacuum is different. Most industrial vacuum pumps pump out the gas in the vacuum chamber to create a vacuum environment for production; The medical vacuum cleaner is mainly used for vacuum cleaning, mainly for extracting various kinds of liquid (of course, the purpose is to extract anesthetic waste gas, etc.) therefore, when selecting the medical vacuum pump, the main concern is how much volume flow the vacuum pump can provide under the design pressure and how much liquid can be sucked out per unit time. This is also different from the choice of industrial vacuum pump. The corresponding pumping speed and inlet pressure and many other factors.

Solution to overload of anticorrosive vacuum pump

As for the anti-corrosion vacuum pump, how much do you know about it, and what measures should be taken for overload when using it? We should have a simple understanding. The following will introduce what measures should be taken for overload of anti-corrosion vacuum pump: 

1. Hydraulic coupling: the use of hydraulic coupling can also prevent the overload of anti-corrosion vacuum pump, so that the pump can work under high pressure difference;

2. Vacuum electrical components are used to control the inlet pressure of anti-corrosion vacuum pump: pressure sensitive elements such as vacuum diaphragm relay or electric contact vacuum pressure gauge are installed at the inlet pipeline of anti-corrosion vacuum pump. After the vacuum system is started, when the pressure at the inlet is lower than the given value, the pressure sensing element will send out a signal to start the anti-corrosion vacuum pump through the electrical control system. If the inlet pressure of the pump is higher than the specified value, the vacuum pump will be shut down automatically to ensure its reliable operation;

3. Mechanical automatic pressure regulating bypass valve: the bypass valve is installed on the bypass pipe between the outlet and inlet of the anti-corrosion vacuum pump. This valve controls the pressure difference between the pump inlet and outlet not to exceed the rated value. When the pressure difference reaches the rated value, the valve will open automatically by the differential pressure, so that the outlet and the inlet are connected, so that the pressure difference between the inlet and outlet is reduced rapidly. At this time, the anti-corrosion vacuum pump works under almost no pressure difference load. When the vacuum pump passes through the rated value, the pump will close automatically when the differential pressure is lower than the rated value. The anti-corrosion vacuum pump with bypass relief valve can be started at the same time with the previous pump, which makes the unit operation simple and convenient.

Oil free environmental protection dry screw vacuum pump

Why is the environmental protection problem of oil-free dry screw vacuum pump? Simply speaking, compared with oil vacuum pump, the extracted gas of oil-free dry screw vacuum pump will not be mixed with oil and gas, which can obtain a clean vacuum environment. In addition, if the extracted gas is corrosive to the oil, or contains a large amount of water and other substances that can damage the oil, then the oil vacuum pump cannot be used. As there is oil, the oil in the vacuum pump is usually used for lubrication and sealing. If the oil is corroded or emulsified, the vacuum pump can not work normally. 

Oil free dry screw vacuum pump is one of the essential equipment in the field of vacuum equipment. Power, oil, pharmaceutical, food and other areas closely related to people's life have different market demand for vacuum pump equipment. Under such huge demand, China's vacuum pump enterprises constantly stop the adjustment of industrial structure, so as to meet the needs of various categories At the same time, it can also stop the whole vacuum pump equipment to improve its technology.

After analyzing the current situation of domestic vacuum pump in recent years, it is found that there is no large pump group which can represent the whole vacuum pump industry market. Moreover, while the domestic vacuum pump market demand is expanding day by day, foreign advanced enterprises have numerous factories in China, and relying on their strong technical strength, they share the "share" with domestic vacuum pump enterprises. The promotion of competitiveness makes domestic vacuum pump enterprises pay more and more attention to the technology improvement of their own brand of vacuum pump equipment.

Analysis on installation of water ring vacuum pump unit

The key to the installation technology of water ring vacuum pump unit is to determine its installation height. This height refers to the vertical distance between the water surface of water source and the center line of impeller, which can not be confused with the allowable vacuum height. The vacuum value on the water ring vacuum pump's water inlet section is indicated on the nameplate or product manual of the water ring vacuum pump, and it is under 1 standard atmospheric pressure and when the water temperature is 20 ℃, The installation height of water ring vacuum pump should be allowed to absorb the vacuum height after deducting the loss head of the suction pipe. It needs to overcome the actual terrain suction height. 

The installation height of water ring vacuum pump unit should not exceed the calculated value, otherwise it will not be able to pump water. In addition, the influence of the calculation value is the resistance loss head of the suction pipe. Therefore, the shortest pipeline layout should be adopted, and the fittings such as elbows should be installed as few as possible, and the water pipe with larger diameter can also be considered to reduce the flow velocity in the pipe. It should be pointed out that when the elevation and water temperature of the water ring vacuum pump installation site are different from the test conditions, the calculated value should be corrected. That is, the atmospheric pressure at different altitudes and the saturated vapor pressure when the water temperature is higher than 20 ℃.

When the water temperature is below 20 ℃, the saturated vapor pressure can be ignored. In terms of pipeline installation technology, the suction pipe should be strictly sealed, and no air or water leakage is allowed. Otherwise, the vacuum degree at the water inlet of the water ring vacuum pump will be destroyed, and the water output of the water ring vacuum pump will be reduced, and even the water can not be pumped in serious cases. Therefore, it is necessary to do a good job in pipeline interface work to ensure the construction quality of pipeline connection.

Roots vacuum pump with relief valve Installation

1. Roots pump should be installed in dry, ventilated and clean place 

2. Roots pump should be installed horizontally, and the gap between pump and wall or other objects should be kept at least 300 mm. The oil window part of the pump shall be provided with space for easy observation of oil level.

3. When connecting the power supply, pay attention to the rotation direction of the motor. From the tail of roots pump motor, the rotation direction of motor shaft should be clockwise.

Operation steps: turn on the three-phase power supply of the motor, click the start button of the motor to check whether the steering direction is correct. If the steering direction is opposite, replace any two of the three power supply terminals.

4. The pipeline connecting roots pump and pumped vessel shall be clean, dry and free of leakage. The diameter of pipeline shall not be less than the inlet diameter of roots pump as far as possible, and the length shall be short to reduce the loss of pumping speed, and there shall be no leakage at the joint of pipeline.

5. If the extracted gas contains dust or granular substances, a suitable air inlet filter should be installed at the inlet of the pump to avoid damage to roots pump and front stage pump by dust or granular substances. (after the filter is installed, the pumping speed and limit pressure of roots pump will be affected, and the influence degree varies with the structure of the filter).

Waste heat recovery of air compressor

Air compressor in the process of work produces very large heat energy, but let it white out to the air is a very pity, so there is what we call air compressor waste heat recovery. The waste heat recovery of air compressor is to transfer the heat of high temperature oil of air compressor to cold water through superheat exchange technology. The cold water is heated and flows into the heat preservation water tank, so as to achieve the purpose of heat recovery. 

Because 73% of the heat energy of the air compressor is in the oil, and the technical treatment and heat exchange of the oil will produce a continuous stream of hot water, that is, the air compressor can work under constant temperature, and can meet the needs of the factory or life of hot water, kill two birds with one stone, and the hot water generated by the waste heat recovery technology of air compressor does not need any additional cost, which reduces the cost Less investment by factories to make hot water. Air compressor waste heat recovery is a very environmental protection and energy saving way.

Frequency conversion series air compressor chemical industry

Chemical industry in the production process often uses and produces corrosive gases, liquids and dust, a large number of flammable and explosive dangerous substances, as well as irritant, polluting and other toxic substances, so chemical plants are mostly built on water. In the design of building structure and production equipment will be considered in all aspects of anti-corrosion, fire, explosion-proof measures. With the rapid development of science and technology, modern chemical plants mostly use energy-saving, intelligent regulation and centralized control of chemical equipment. 

Clean and stable compressed air is indispensable in the complex production process of chemical plant. The compressed air from the air compressor is compressed and discharged into clean and stable gas after passing through a set of precise post-treatment system of gas storage tank, dryer and filter, and then divided into two pipelines: one is used to drive some pneumatic equipment, the other is used to produce nitrogen and chemical raw materials. Therefore, a high quality air compressor and post-treatment system will be directly related to the production process of the whole chemical plant.

Market prospect of oil free scroll vacuum pump

Oil free scroll vacuum pump has the characteristics of oil-free, clean, low vibration noise and low energy consumption, so it has broad development prospects and market potential. However, due to the complex design and manufacturing technology of the scroll pump, mass production has not been realized in China at present, which can not meet the increasing market demand, so it can only rely on imported products with high price and inconvenient after-sales service. In addition, affected by many factors such as the development of the market and the degree of understanding of users, the vortex pump has not formed a virtuous cycle in China. 

Even so, the actual annual demand of scroll pumps in China is still more than thousands. It can be considered that with the emergence of high-precision CNC machine tools and machining centers, opportunities have been brought for the development of vortex technology, and the key manufacturing technology has been broken through; At the same time, China now has a certain number of experienced professionals in design, research and development, testing, analysis and use, and are committed to the technical development of pumps. It is believed that in the near future, domestic oil-free scroll vacuum pumps with moderate price, reliable performance and batch production will become the mainstream products suitable for the requirements of China's market. Therefore, increasing investment, R & D and mass production of scroll vacuum pump suitable for domestic demand has become one of the important tasks of the whole vacuum acquisition industry in China.

Tightness of vacuum pump system

The tightness of the vacuum pump system is extremely important for the user's use process. Some users will call to say that the vacuum degree can not meet the requirements after receiving the water ring vacuum pump of our company. After the professional guidance of our company's technical personnel, excluding other reasons, it is found that the leakage of the user's pipeline causes the vacuum degree not to go up. How much does the leakage rate bring to the performance of the vacuum pump system The impact of! 

In practical application, when it is found that there is air leakage in vacuum pump, it is necessary to distinguish whether there is air leakage in vacuum degree or pipeline, because the solutions adopted by the two are different

1) Methods to check whether there is air leakage in the vacuum pump: directly measure the air inlet of the vacuum pump with a vacuum meter to see how much vacuum degree can be reached if the pump is tested by single measurement. If it reaches the specified standard, the possibility of air leakage of the vacuum pump is ruled out;

2) Check whether there is air leakage in the pipeline: the most commonly used method is to test whether there is air leakage in the pipeline or remove a section of the pipeline, connect one end to the pump without air leakage, and measure the other end with a vacuum gauge. Through this method, the air leakage point can be identified.

Screw vacuum pump product market

Because the screw vacuum pump only needs a pair of screws, and there is a certain gap between the screw and the screw, so when the screw vacuum pump is working, the noise is very low, the speed is uniform, the most important thing is that there is no need for lubricating oil during the operation, so the dry screw vacuum pump can operate in the environment with a lot of water vapor, which is a very energy-saving vacuum product. 

Now in the market with the continuous screw vacuum pump products, the general vacuum pump can not be satisfied with the oil-free condition, so the dry screw vacuum pump competition in the market is growing, so the screw vacuum pump has replaced many vacuum pump products, many oil vacuum pump has been replaced by oil-free vacuum pump, now many companies have replaced screw vacuum pump 。

Therefore, the market of screw vacuum pump is getting better and better, so the prospect of screw vacuum pump is naturally very good. The future development trend of screw vacuum pump is environmental protection: with the increasingly serious pollution problem in recent years, the topic of environmental protection has been mentioned again and again, so the production and production of various products in the future should pay more attention to environmental protection.

What problems do vacuum pump need to deal with to achieve the purpose of environmental protection and energy conservation and emission reduction? The answer is noise reduction. The development of new materials and new skills will promote the reduction of oscillation and noise. We will work together to deal with the problem of oil injection and oil leakage of pumps, so as to achieve the purpose of cleaning the environment. We will carry out personalized and refined development: we will satisfy the increasingly diversified needs of different categories.

Water ring vacuum pump has strong corrosion resistance

Compared with the most common SK series water ring vacuum pump, water ring vacuum pump has the characteristics of strong corrosion resistance, high limit vacuum degree and large exhaust volume. It is widely used in food, petroleum, chemical industry, metallurgy and other professional fields, and can also pump various gases and corrosive gases without solid particles. 

There are two main shock absorption methods: the transmission system is reformed. In order to reduce the vibration intention of the motor and transmission shaft, SK water ring vacuum pump is used to transfer the rigid connection with the transmission shaft into elastic connection. The elastic sleeve pin coupling is used to adjust the maximum compensation displacement and compensation angle, so that the vibration of the motor and drive shaft can be compensated through the elastic coupling and will not be directly transmitted to sk water ring vacuum pump.

Considering that it is difficult to reinforce SK water ring vacuum pump, the method of welding "reinforcing rib" in the outlet steel pipe is adopted. Along the inlet and outlet direction, the flange at both ends of the connecting steel pipe between the outlet pipe of SK water ring vacuum pump and the outlet valve can be consulted by the seller for welding with several steel plates of specified thickness and width. The stiffness of steel pipe is added to reduce deformation and resist displacement.

Power supply configuration of claw vacuum pump

Claw type vacuum pump, claw type air pump, claw type water pump, etc., after connecting the power supply, the power supply voltage should be stable under any load and working condition. With switching power supply is a better solution. If the power supply is not regulated, the voltage may be very high when the pump is not connected. Once the pump is connected, the power supply voltage will drop sharply. Even if the voltage after connecting the pump is equal to the rated working voltage. At this time, the power supply voltage will fluctuate abnormally, leading to the pump's work will be completely disordered. 

It is also not advisable to divide and depressurize by resistance, because the working current of pump will change when the load of gas (water) circuit changes, which will lead to the change of resistance voltage. Therefore, the power supply must have voltage stabilizing function. In actual purchase, with and without voltage stabilizing function, the price difference is very small, it is recommended to buy with voltage stabilizing function.

The output current that the power supply can provide must be larger than the working current of the pump, so as to ensure the energy demand of the pump. And choose power supply, must not choose the price is too cheap switching power supply. In order to attract customers to buy this kind of power supply, the parameters usually have false mark and false report.

System composition of main vacuum system

The vacuum system of vacuum gas drying equipment consists of two parts: main vacuum system and leakage pump system. 

The main vacuum system is composed of the main pump (roots vacuum pump), front stage pump (rotary vane vacuum pump or slide valve vacuum pump), front stage condenser, central condenser, exhaust separator, steam pressure gauge, pipes, valves and other components. The effect is to vacuum the vacuum tank in the preparation stage, high vacuum stage and vacuum pump oil.

Although the kerosene in the vacuum system is exhausted during the depressurization stage, there is still residual kerosene in the insulation data. Therefore, in the high vacuum stage, the gas entering the main vacuum system still contains a certain amount of kerosene vapor, which will condense into liquid in the front condenser and the central condenser, while the water vapor component in the gas is discharged by the front stage pump and collected in the exhaust condenser.

The two front-stage pumps are also responsible for the mission of urgent spare time when the heat generator and vacuum tank are in trouble. Emergency evacuation is carried out through the pipe of valve 3 through the main condenser of the condensing system. The condenser is used to ensure that the hot gas of the fire oil condenses during the time of extraction, so as to make the steam of the fire oil less enter the vacuum unit.

Double stage slide valve vacuum pump with high pumping speed

For a long time, there are many difficulties and challenges in the development of double stage slide valve vacuum pump in our country. The production of 2H-150 and other products took more than 20 years after the standard was formulated. In fact, the design and manufacture of double stage slide valve vacuum pump with large pumping speed will encounter a series of problems, such as dynamic balance, control of two-stage oil supply, noise reduction and so on. However, the double stage slide valve vacuum pump with high pumping speed has a wide application prospect 

Due to the structural characteristics, the capacity of the slide valve pump is much larger than that of the rotary vane pump. Because the slide valve vacuum pump can work in poor vacuum environment for a long time, it is often used in large vacuum equipment. The limit pressure of single-stage pump is between 0.6 PA and 1.3 PA (gas shut-off) and that of double-stage pump is 0.06 PA.

Pumping speed ≥ 150L / s can be regarded as a large-scale slide valve pump. For a long time, there are only 70L / s two-stage slide valve pump in China. However, if there is a double-stage slide valve vacuum pump with high pumping speed, it is particularly beneficial to simplify the unit structure of vacuum equipment, reduce power consumption, achieve energy-saving effect, simplify operation and improve control reliability.
