Summary of 2BV type water ring vacuum pump
The 2BV water-ring vacuum pump is suitable for pumping gas and steam. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When transformer oil is used as working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum degree), which can completely replace the reciprocating vacuum pump. When the suction pressure of the liquid ring vacuum pump is close to the limit vacuum for a long time, the 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, with the increase of exhaust pressure will cause the increase of 2BV pump power, the order should be marked exhaust pressure to select the appropriate motor power.
As a new generation of energy-saving products, 2BV water-ring vacuum pump will replace SK, 2SK series water-ring vacuum pump and W, WY, WL series reciprocating vacuum pump with excellent performance and many advantages.
2BV2-Ex and 2BV6 series water-ring vacuum pumps/compressors are mainly used for extracting explosive gases and working in various flammable and explosive environments. Their performance parameters are the same as those of 2BV2 and 2BV5 series.
2BV series stainless steel vacuum pump can be used in all kinds of corrosion-resistant occasions and cleanliness requirements of higher occasions. According to the working condition of 2BV series stainless steel vacuum pump, all over-flow parts: pump body, pump cover, disk, impeller material can be selected SUS304 (0Cr18Ni9), SUS316 (0Cr17Ni12Mo2), SUS316L (00Cr17Ni14Mo2) and other stainless steel materials, pump shaft material: 2Cr13 or 0Cr18Ni12Mo2Ti.
The mechanical seal of 2BV water ring vacuum pump adopts imported products, and the seal can be made of fluororubber or polytetrafluoroethylene.
Compared with the same type of water ring vacuum pumps, such as SK, 2SK and SZ, they have the following characteristics:
The coaxial type direct connection design of 2BV type water ring vacuum pump pump saves space and is easy to install.
The 2BV type water ring vacuum pump adopts all imported mechanical seals as the standard configuration.
2 BV type water ring vacuum pump is equipped with cavitation protection pipe interface. If working under extreme pressure, opening the cavitation protection pipe interface (or connecting with the separator) can eliminate cavitation sound and protect the pump under the condition of guaranteeing the suction effect to the maximum extent.
Aluminum bronze impeller has high strength and durability, and improves the corrosion resistance of the 2BV type water ring vacuum pump. If the overcurrent parts are made of stainless steel, they can work in a more demanding environment.
The unique design of flexible exhaust port will not produce over-compression, which ensures that the 2BV water-ring vacuum pump has the best efficiency in its performance range.
All Y2 series motors are adopted, with protection level IP54 and IP55 (usually IP44).
2BV type water ring vacuum pumps are all imported with NTN or NSK bearings.
