When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure, the larger of the power of the compressors. So it is necessary that the data of the discharge pressure is provided to choose the proper motor.
2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.
2BV6 water ring vacuum pump/compressor (pump's material is stainless steel)
2BV2-Ex, 2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.
2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.
According to the working situation, the material of all the parts where the liquid flows (i. E. Pump casing, pump cover, port plate, impeller)are made of various stainless steel as bellow:
SUS304(0Cr18Ni9)
SUS316(0Cr17Ni12Mo2)
SUS316L(00Cr17Ni14Mo2)
The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
The mechanical seals are used the John Crane products and the seals material is optional for FPM or PTFE.
1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages.
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use;
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems.
4. Petroleum industry: oil, gas pipeline.
5. Coal industry: coal transport, ventilation systems.
6. Chemical engineering: chemical containers, especially corrosive fluid delivery
pipelines.
7. Electric power engineering: circulating water pipeline.
8. Road engineering: crossing roads and railways have a large traffic load of water
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes.
9. The laying of pipes in a corrosive environment.
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on;
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc.
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communications, communication cables, optical cable protection pipe.
14. Water storage system: used to intercept the slow water storage system.
15. Special application: thermal winding wall winding pipe can also be used for special
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
2BV Single Stage Vacuum Pump
CHINA AOLI MACHINERY GROUP
2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i. E. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i. E. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump.
