The working principle summary:
Starting electrical machinery, pump enters working state, and when pump shaft drove rotor, rotor banding movable pendulum and rolls blade and turn clockwise, pendulum rolled A that blade enters bore of stator in the process of B, and blade is shown the nest mortar and is opened gradually, and volume becomes greatly gradually, produces negative pressure of vacuum suction fluid; When pendulum roll blade enter B to C and D in the process of A, blade gets up the high and low pressure chamber isolating seal in the stator.Because when the blade of front does not also turn over CD, and the blade of back has turned over B, A, so the high and low pressure chamber in the stator is isolated by blade constantly and seals.Enter C in the process of D when pendulum rolls blade, it is closed gradually that blade is put back the nest mortar, and the volume generation pressure that diminishes gradually extrudes the exhaust port of fluid from pump.The pressure of the inlet/outlet of pump can directly show (referring to Fig. 3, Fig. 8) on vacuum gauge and pressure gauge.
When pump shaft turned clockwise, pendulum rolled on the inside diameter surface of annular groove guide rail that interior side wheel (zanjon bearing) that the blade two ends connect is pressed on front and rear cover, and rolling-operation in its surface.When pump shaft when rotation inhour, pendulum rolls the outer side wheel (zanjon bearing) that the blade two ends connect and is pressed on the external diameter surface of annular groove guide rail, and rolling-operation (referring to Fig. 4, Fig. 9) in its surface.When in a single day pump reverses, the stuck damage that causes can not take place, but under normal circumstances do not allow to reverse like this.
Swingrolling vane pump has minimum running resistance, and its reason is: (1) acts on the pendulum centrifugal force and the working pressure of rolling on the blade and acts on the annular groove guide rail of front and rear cover by balance staff, swing arm, roller shaft, roller, and roller is rolling-operation on guide rail.This moment, pendulum rolled swing termination and atomic little gap of maintenance, diameter of stator bore surface of blade, and it rotates termination and also there is an atomic little gap on fossa trochanterica mortar groove surface, and pendulum rolls blade and rotor and diameter of stator bore surface and all do not rub.(2) micro-gap of maintenance between end face by being assemblied in the adjustment of the adjustment nut on rotor and the pump shaft front end, making the both ends of the surface that are fixed on end plate before and after the rotor and front and rear cover and the stator two ends makes it not take place to rub.(3) end plate rolls blade with pendulum and is contained in same rotor and synchronous operation, the high-speed slide friction when not having relative movement, the low speed sliding friction when only having blade oscillating.(4) built-in roller type pump pendulum rolls roller on the blade directly at diameter of stator bore surface rolling-operation, because roller diameter is slightly larger than the swing termination diameter that pendulum rolls blade, so blade oscillating termination and diameter of stator bore surface still keep floating of a kind of contactless pressure, same not friction.
