Overview

The 2BV water ring vacuum pump is suitable for extracting gases and water vapor, and the suction pressure can reach 33mbar absolute pressure (97% vacuum degree). When using transformer oil as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum degree), which can completely replace reciprocating vacuum pumps. When the liquid ring vacuum pump operates for a long time under suction pressure close to the limit vacuum, a cavitation protection tube should be connected to protect the pump and eliminate cavitation noise. When used as a compressor, its pressure Z can reach up to 0.26MPa (absolute pressure). When used as a compressor,

12BV water ring vacuum pumpOverview:

2BV water ring vacuum pumpSuitable for extracting gases and water vapor, the suction pressure can reach 33mbar absolute pressure (97% vacuum degree). When using transformer oil as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7mbar absolute pressure (99.3% vacuum degree), which can completely replace reciprocating vacuum pumps. When the liquid ring vacuum pump operates for a long time under the suction pressure approaching the limit vacuum, a cavitation protection tube should be connected to protect the pump and eliminate cavitation noise. When used as a compressor, its maximum pressure is 0.26MPa (absolute pressure). When used as a compressor, the increase in exhaust pressure will cause an increase in the power of the 2BV pump. When ordering, the exhaust pressure should be specified to select the appropriate motor power.
　　
2BV water ring vacuum pumpAs a new generation of energy-saving products, it will fully replace the SK, 2SK series water ring vacuum pumps and W, WY, WL series reciprocating vacuum pumps with excellent performance and numerous advantages.
　　
2BV water ring vacuum pumpMainly used for extracting explosive gases and working in various flammable and explosive environments, its performance parameters are the same as the corresponding models of 2BV2 and 2BV5 series.

The 2BV series stainless steel vacuum pump can be used in various occasions with high corrosion resistance requirements and high cleanliness requirements. According to the operating conditions, all overcurrent components of the 2BV series stainless steel vacuum pump, including the pump body, pump cover, disc, and impeller, can be made of various stainless steel materials such as SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2), etc. The pump shaft material is 2Cr13 or 0Cr18Ni12Mo2Ti

2BV water ring vacuum pumpThe mechanical seal adopts imported products, and the sealing components can be made of fluororubber or polytetrafluoroethylene

Compared to similar water ring vacuum pumps such as SK, 2SK, SZ in China, it has the following characteristics:

·The 2BV water ring vacuum pump has a coaxial direct connection design, which saves space and is easy to install.
·All 2BV water ring vacuum pumps are equipped with imported mechanical seals as standard.
·All 2BV water ring vacuum pumps are equipped with cavitation protection pipe interfaces. If working under extreme pressure, opening the cavitation protection pipe interface (or connecting it to the separator) can eliminate cavitation noise and protect the pump while ensuring maximum suction effect.
·The aluminum bronze impeller has high strength, durability, and improves the corrosion resistance of the 2BV water ring vacuum pump. If the overcurrent components are made of stainless steel material, they can work in more demanding environments.
·The unique flexible exhaust port design prevents over compression, ensuring that the 2BV water ring vacuum pump has the best efficiency within its performance range.
·All use Y2 series motors with protection levels of IP54 and IP55 (usually IP44)
·All 2BV water ring vacuum pumps use NTN or NSK imported bearings

42BV water ring vacuum pumpWorking principle:

The impeller of the 2BV water ring vacuum pump is eccentrically installed inside the pump body. When starting, a certain height of water is injected into the pump. Therefore, when the impeller rotates, the water is subjected to centrifugal force and forms a rotating water ring on the inner wall of the pump body. The lower inner surface of the water ring is tangent to the hub and rotates in the direction of the arrow. During the first half of the rotation process, the inner surface of the water ring of the 2BV water ring vacuum pump gradually separates from the hub, forming a closed space between the impeller blades and the water ring. As the impeller rotates, the space gradually expands, the gas pressure in the space decreases, and gas is sucked in from the disc suction port; During the latter half of the rotation, the inner surface of the water ring gradually approaches the hub, and the space between the blades gradually shrinks. The gas pressure in the space increases, and when it exceeds the pressure at the exhaust port, the gas between the blades is discharged from the disc exhaust port. So every time the impeller rotates, the space between the blades absorbs and exhausts once, and many spaces work continuously,2BV water ring vacuum pumpContinuously suction or compress gas.
　　
2BV water ring vacuum pumpDue to the generation of heat during work, the working water ring generates heat, and a portion of the water and gas are expelled together. Therefore, it is necessary to continuously supply water to the pump during work to cool and replenish the water consumed in the pump, in order to meet the working requirements of the pump.

when2BV water ring vacuum pumpWhen the discharged gas is no longer used, a gas water separator is connected to the exhaust port of the 2BV water ring vacuum pump. After the exhaust gas and some of the carried water are discharged into the gas water separator, the gas is separated and the gas is discharged through the exhaust pipe. The remaining water is supplied to the pump through the return pipe for continued use. With the extension of working hours, the temperature of the working water will continue to rise. At this time, cold water needs to be supplied from the water supply pipe to reduce the temperature of the working water and ensure that the pump can meet the required technical requirements and performance indicators.
