Humen good vacuum pump, Lei Bo electrical equipment, Humen vacuum pump

Vane vacuum pumps used in over rotary vane vacuum pump rotor slot, pump rotor and blades are sealed in vacuum inside the cylinder, using a vacuum pump oil as a lubricating media plays the role of a vacuum pump vanes and add a touch area of ??the cylinder and then to the aspiring state ultimate vacuum. If the pump blade is too short to have a good quality thin Humen vacuum pump, the resulting lack the degree of vacuum pumps and even cause serious problems occur. Here, we find the strength advocate blade should be in the choice of vacuum pump, the integrity of operating companies have proven legitimate supplier. Best is to find some professional manufacturers supply these goods! According to the working principle, be divided into two-stage pump vane pump (also called: Bipolar rotary vane vacuum pump) leaves two blades and a single-stage rotary vane vacuum pump. During two-stage pump vanes in the market domestically produced goods, mostly French Leybold, Edward mostly Humen brand vacuum pump, domestic brands have mostly 2X series models. It is not the same type, not the same brand, the vacuum pump vanes and raw materials are not the same scale. Roots Roots pump works pump chamber in the pump, there are two "8" -shaped perpendicular rotor mounted on a pair of parallel shafts, a pair of gears by the transmission 1 as a reverse drive ratio synchronized with each other rotary motion. Between the rotor, between the rotor and the casing inner wall to maintain a certain gap, a high speed operation can be realized. Since the Roots pump is a vacuum pump without internal compression, the compression ratio is usually very low, so high, the need for pre-vacuum pump. Limit Roots vacuum pump depends on the pump in addition to the structure and manufacture of precision itself, but also depends forepump ultimate vacuum. In order to improve the ultimate vacuum pumps, vacuum election Which Humen, Roots pumps can be used in tandem. Works with Roots pump Roots blower similar. Due to the continuous rotation of the rotor, it has been pumping gas from the intake port to the space v0 between the rotor and the casing where Humen vacuum pump, and then discharged through the exhaust port. Since inspiratory v0 space is completely closed state, so there is no gas in the pump chamber compression and expansion. But when the top edge of the rotor turned vent, when v0 space communicates with the exhaust side, due to the higher gas pressure exhaust side, then rushed back part of the gas space v0 in order to enable gas pressure suddenly increased. When the rotor continues to rotate, the gas discharge pump.
