Liquid ring vacuum pump is a kind of crude vacuum pump. The limit vacuum it can obtain is 2000 ~ 4000Pa, and the vacuum degree of the unit composed of liquid ring vacuum pump can reach 1 ~ 600Pa. Liquid ring vacuum pump can also be used as compressor, which is called liquid ring compressor. It belongs to low-pressure compressor, and its pressure range is 1 ~ 2 × 105 PA gauge pressure. So, what are the models of liquid ring vacuum pump? The model of liquid ring vacuum pump produced by each manufacturer is different. Let’s introduce EVP vacuum pump in detail!
1. 2BV series liquid ring vacuum pump adopts the coaxial direct connection design of the pump, which saves space and is easy to install; uses the mechanical seal as the standard configuration, which eliminates the leakage and is easy to maintain; operates stably, and the noise can be as low as 62 db; the uniform corrosion-resistant design of bronze impeller improves the corrosion resistance of the pump, while the stainless steel material is more suitable for more demanding applications; the unique flexible alarm arrangement The design of guide port will not produce over compression, which ensures that the efficiency of 2BV liquid ring vacuum pump is better in its performance range.
2. 2be liquid ring vacuum pump and compressor are usually used to pump the gas which does not contain solid particles, is insoluble in water and has no corrosiveness, so as to form vacuum and pressure in the closed container. By changing the result material, it can also be used to suck corrosive gas or use corrosive liquid as working fluid. 2be liquid ring vacuum pump is widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, stone tools, coal washing, mineral processing, chemical fertilizer and other industries.
3. SK liquid ring vacuum pump and compressor are widely used in mechanical, petrochemical, pharmaceutical, food, sugar industry and electronic fields. Because the compression process of gas is isothermal in the working process, it is not easy to cause danger when compressing and drawing explosive gas, so it is more widely used. The working vacuum range is -0.03-0.08mpa.
4. SK type direct liquid ring vacuum pump is widely used in electronic device manufacturing, vacuum drying, vacuum evaporation, vacuum concentration, vacuum moisture return, vacuum impregnation, filtration, impregnation, wax coating, welding, smelting, chemical, light industry, petroleum, medical, pharmaceutical, printing and dyeing, semiconductor, food, atomic energy, textile and other scientific research institutions, colleges and universities, industrial and mining enterprises. Sk type direct water ring vacuum pump can not be used to pump gases with high oxygen content, toxic, explosive or chemical reaction with pump oil, nor can it be used as compressor or transfer pump.
5. 2SK liquid ring vacuum pump is widely used in vacuum evaporation, vacuum concentration, vacuum moisture return, vacuum impregnation, vacuum drying and vacuum smelting in food, textile, chemical, pharmaceutical and metallurgical industries and electronic fields. 2SK series is used for working conditions with suction pressure lower than -0.08mpa, and 2SK series is used for working conditions with suction pressure lower than -0.096mpa.
6. CL liquid ring vacuum pump and compressor are used to pump or compress air and other non corrosive, water-insoluble and solid particles free gases, so as to form a certain degree of vacuum in the sealing system. They are commonly used in vacuum evaporation, vacuum concentration, vacuum drying, vacuum suction filtration, vacuum feeding and other technological processes. But it is widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and electronic fields. In the process of working, the compression of gas is isothermal, so it is not easy to cause danger when compressing and pumping flammable and explosive gas, so SZ type water ring vacuum pump is more widely used.
7. DLV liquid ring vacuum pump can pump air or other non corrosive, water-insoluble and solid particles free gases. The lower suction pressure is -0.086mpa. It is widely used in machinery, petroleum, chemical, pharmaceutical, food and other industries. It is especially suitable for large-scale water pump.
There are many models of liquid ring vacuum pump. The above models are only common in the market at present. If you want to know more about them, you can consult the EVP vacuum pump manufacturer. EVP vacuum pump manufacturer is a company specializing in the research and development and manufacturing of vacuum pumps and supporting products, with good reputation, strong strength and reliability.
