Water Ring Vacuum Pump Separator

What is a water ring vacuum pump separator:

The main function of the water ring vacuum pump separator is to separate the liquid from the entrainment in the gas, and according to the different parts of the installation position, the pre gas liquid separator and the rear gas liquid separator are divided.

Pre-gas-liquid separator is mainly used to separate the liquid entrained in the pumped gas, such as the vacuum pump used in the paper industry more.

The post-installed gas-liquid separator is mainly used to separate a large amount of liquid entrained in the discharge gas when the water ring vacuum pump and compressor work.

The design pressure and working pressure of separators can be roughly divided into three types:
The first is a separator that works in a vacuum. The design pressure is from -0.1Mpa to -0.02Mpa. The standard for design and calculation is GB150 – 1998 steel pressure vessel. The products of the company mainly include pre – splitter.

The second kind is the separator working in the normal pressure state. The design pressure is from more than -0.02Mpa to less than 0.1Mpa. The standard of design and calculation is JB/T4735–1997 “steel welding permanent pressure vessel”. The products of the company are mainly used in the separator of various vacuum pumps.

The third kind is a separator working under positive pressure. The design pressure is from 0.1Mpa to no more than 35Mpa. The rules and standards based on the design and calculation are “Pressure Vessel Safety Technical Supervision Regulations” and GB150 – 1998 “steel pressure vessel”.vacuum-pump-application-in-the-freeze-drying-industry

Water ring vacuum pump nouns interpretation:
Working pressure: pressure vessel withstanding internal pressure, the highest working pressure refers to the normal use of the process, the top may appear the highest pressure;

The maximum pressure is the maximum pressure difference that may occur during the normal use of the pressure vessel, and the maximum pressure difference may appear on the top of the jacket container.

Design pressure: design pressure refers to the highest pressure at the top of the set of the set, with the corresponding design temperature as the design load condition, the pressure vessel design pressure should not be lower than the maximum working pressure, the pressure vessel equipped with safety relief device, its design pressure should not be lower than the opening pressure of the safety valve or the explosion of the blasting piece.

VACUUM PUMP IS USED IN THE SEMICONDUCTOR MANUFACTURING INDUSTRY

Vacuum pump, as a main production equipment in semiconductor manufacturing industry, is increasingly required for safety and reliability. When the rotary pump for hydrocarbon oil seals is used for aeration such as photoresist and degumming, explosion sometimes occurs. Atomized oil mist, hot oil vapor, friction, compression, higher temperature, foreign matter, possible static electricity, once combined with oxygen may endanger the environment. And these factors are all in the vacuum pump. The use of nitrogen and other inert gases as gas detonation in the pump and the use of nitrogen to reduce oxygen concentration in the tank (less than 25% oxygen concentration) can reduce the risk of explosion. This method has been adopted by the semiconductor manufacturing industry.vacuum-pump-is-used-in-the-semiconductor-manufacturing-industry

The new vacuum pump will be more suitable for corrosion requirements in IC manufacturing processes, such as ceramic, fusible and precious metals.

The new pump will retain all the advantages of the current pump without the disadvantages of the current pump. In terms of cryogenic pumps, the total reliability of cryogenic generators and compressors will be further improved. In terms of rough pumping, the clearance degree will be increased by at least one order of magnitude. A Japanese electronics company estimates that turbopumps and cryopumps will replace diffusion pumps in the next few years because of their cleanliness. The new type of magnetic bearing turbine molecular pump will be used in the semiconductor manufacturing industry.application-of-vacuum-pump-in-food-industry

The pump will have more computer interfaces or even self diagnosis. Because of the serious chemical corrosion, the self-monitoring impeller pump will replace the piston pump, and the piston pump will become a backward technical representative. After 50 years, many semiconductor manufacturing can even be brought to outer space to carry out! The future vacuum pump will be only a valve behind the processing room for a far-reaching outer space.vacuum-unit-for-distilling-and-recovery-of-fatty-acids

Vacuum Unit For Distilling And Recovery Of Fatty Acids

In the stage of fatty acid distillation, vacuum unit must be evacuated by vacuum unit to reduce the boiling point of the material and then heat and evaporate and then cool back to achieve the ideal effect. How to select the correct vacuum unit in the process of fatty acid distillation recovery is a great concern.

With the improvement of the people’s living standard, the consumption of edible oil has been increased year by year, resulting in a large amount of waste oil and fats and fats. Many new technologies and methods have been developed for the treatment and application of these waste oils and waste materials. In China, a whole industrial chain of collection, production and application has been formed.

The source of waste oil:

1. Discarded oils and fats from restaurants and canteens.

2. slaughtering enterprises’ leftovers.

3. leather processing industry. Sources of oily leftovers: mainly from the leftovers produced by edible oil processing enterprises, such as cottonseed oil, soybean oil, rapeseed oil, peanut oil and other sludge and soap horn.Closed_Cycle_Water_Ring_Vacuum_System

Application Of Vacuum Pump In Food Industry

One of the most common operations in the food industry is to use a vacuum pump system to move a liquid or solid from one location or processing step to another. The main part of pump transportation is pipeline system and vacuum pump. The type of vacuum pump is very different, and the principle is not the same. The choice should be based on the characteristics of the material to be transported.application-advantages-of-vacuum-pump-in-sugar-industry

The most commonly used is gear pump, no matter what kind of vacuum pump, because the rotor rotates in the pump chamber, resulting in pressure difference, sucking food into the pump chamber and constantly extruding it. Obviously, a closed working chamber must be formed between the gear of the pump and the pump chamber. Although these pumps are also used to transfer liquids and slurries, and sometimes can also transport small pieces of material, but it is possible to crush materials.working-principle-of-water-ring-vacuum-pump-unit

Single helix pumps may be ideal devices for conveying bulk materials but not being crushed. This kind of pump is also called the propelling hole pump, which can form a continuous spiral space between the spiral rotor and the outer wall. When the rotor rotates, the food can be pushed into the same size space by using the helical slope. Therefore, no food, such as corn, grapes or even shrimps, will be destroyed.

No matter which type of vacuum pump is selected, it must be noted that it must be easily disassembled and thoroughly cleaned. Nowadays, stainless steel sanitary pumps are easy to be disassembled in a few minutes with simple tools.application-of-vacuum-pump-in-food-industry

INTRODUCTION TO ROOTS WATER RING UNIT

JZJP2B series Roots water ring unit is a pumping unit composed of ZJ type roots pump as the main pump, 2BV series water ring pump or Roots-Water ring unit as the front pump. In addition to pumping out general gases, it can also suck gas containing water, organic solvents or a small amount of dust. Compared with the general mechanical vacuum pump, it is not afraid of oil pollution, not afraid of water gas and micro dust, but compared with the ordinary water ring vacuum pump, it has the characteristics of high vacuum and high pumping speed in high vacuum condition.Introduction-to-roots-water-ring-unit

Roots Pump-Water ring pump vacuum unit is widely used in chemical industry, electronics, machinery, pharmaceuticals, food sublimation drying, high altitude simulation test and other vacuum systems.application-advantages-of-vacuum-pump-in-sugar-industry

Because of the use of high efficiency and energy saving 2BV series water ring pump for the front stage pump, so JZJP2B series of vacuum units have higher efficiency, compact structure and no leakage than JZJ2S series (2BV pump is a mechanical seal design, different from 2SK series plate seal), corrosion resistance (2BV using aluminum bronze Ye Lun), high protection grade and so on.working-principle-of-water-ring-vacuum-pump-unit

Working Principle Of Water Ring Vacuum Pump Unit

The function of the water ring vacuum pump unit, to a great extent, is in fact to create a preparatory vacuum needed for the roots pump. In general, for the single stage vacuum pump unit, we should pay attention to its own limit really space is not high, and we In fact, it is to pay attention to some things.

In fact, the pre vacuum required by our country’s roots pump is actually higher. In view of this, we are actually not going to use a single level water ring vacuum pump unit as a front pump on the roots pump. In the next word, we should pay attention to the limit. The lower pressure of the two-stage water ring pump to be used as a front-stage pump, so that in fact it can reduce the unit itself a limit pressure.working-principle-of-water-ring-vacuum-pump-unit

A vacuum pump unit and a water ring pump limit pressure is actually 400Pa, in this respect, in a large extent, in fact, can directly meet the general situation of the vacuum needs, but, in terms of the scope of its use, we are actually to pay attention to it itself is also the subject. To a certain limit.

When we directly use two roots pumps in series, and then combined with the vacuum pump unit, in a certain degree, it can greatly increase the limit pressure of the unit itself (can reach 25Pa). It is also because of this, we are actually to pay attention, in this type, the more common in fact is the two roots pump series after the use of double pump directly on the front level of the pump unit.oil-seal-working-principle-and-oil-seal-oil-leakage-measurements

However, as far as the application of the vacuum pump unit is concerned, when we need to have a higher limit pressure, we should pay attention to the combination of three roots pumps and vacuum pump units, and to a certain extent, in a certain extent, it is direct. 1Pa.hydraulic-system-of-vacuum-pump-unit

Application Advantages Of Vacuum Pump In Sugar Industry

A long time ago, sugar mills used piston vacuum pumps because piston vacuum pumps consumed a lot of fuel, vibrated a lot and were easy to break down. Later, the pump produced negative pressure with water jet pump to replace the piston vacuum pump. It has low efficiency, high power consumption, high water consumption and pollution to the environment. It needs to pay a large amount of pollution control cost.application-advantages-of-vacuum-pump-in-sugar-industry

Through the investigation of the characteristics of each link in the sugar industry, a new generation of boiling sugar and evaporation vacuum system, which is suitable for the sugar industry, is designed and produced according to the characteristics that the vacuum filtration requirement of the sugar factory is large and crystallized and the vacuum degree of the sugar is required. The system mainly includes water ring vacuum pump and condenser.the-maintenance-steps-of-the-vacuum-unit

The vacuum pump mainly applies four aspects of sugar industry: sugar boiling, evaporation, suction filter and vacuum water diversion. Compared with the hydraulic jet condenser, the vacuum pump can greatly reduce the water and sewage charges and save costs. The water consumption is only 1/5 of the water jet condenser, which greatly saves the water consumption of the river, especially for the sugar factory which is lack of water resources or the higher requirements for environmental protection.cleaning-of-water-ring-vacuum-pump
