Pump and fan - water ring vacuum pump

Vacuum pneumatic conveying system,to take advantage of vacuum pump keep certain vacuum degree in the pipeline.Have large pump suction type suction pipe section,at startup is also commonly used vacuum pump gas filling water.The commonly used vacuum pump water ring vacuum pump.Water ring vacuum pump is actually a kind of compressor,it extracts container gas pressure motor magnet in above atmospheric pressure,the resistance will be able to overcome the exhaust gas discharged into the atmosphere.Water ring vacuum pump structure diagram is shown in figure 1-8.Twelve blade impeller 1 in a cylinder of the pump shell 2 eccentric.Inject a certain amount of water in the pump.The impeller rotates,motor run capacitor to water to form a water ring pump shell,the inner surface of the ring and the impeller wheel tangent.


Due to different heart pump casing and impeller,the right wheel and water intake space between electricalmotor1.blogspot.com 4 gradually expand,thus forming a vacuum,making gas by the intake pipe 3 into the pump intake space 4.Then gas into the left side,due to the hub ring between volume was increased gradually and the compression pressure,so the exhaust gas space outside the exhaust pipes of 5 and 6 is to pump.Vacuum pump should be ac electric motor constantly replenish water at work to ensure formation water ring and take away the friction heat.China's production of water ring vacuum pump with SZ and SZB,the former top pressure of 205.933 Kpa (as compressor available).SZB is small cantilever type vacuum pump.Table 1-3 is SZ water ring type vacuum pump performance profile.
