What is a Roots pump, the purpose of a Roots pump, the advantages of a Roots pump, vacuum pump, rotary vane pump, ZJ Roots vacuum pump, which uses a pair of 8-shaped rotors to move at constant speed in the pump casing Reverse rotation produces the effects of suction and exhaust. Each rotor is supported by two bearings and uses a pair of synchronous gears to keep the relative position of the two rotors unchanged. Rotors and rotors, rotors and pump bodies, rotors There is a gap between it and the side cover. Since there is no friction in the working chamber, no lubrication is required. The support of the pump rotor adopts a reliable anti-backlash structure, the rotating parts are carefully dynamically balanced, and a high-precision helical gear is used. Therefore, the operation is smooth, the noise is low, the use is more reliable, and the pump can operate under high pressure differential for a long time. The dynamic seal part adopts the company's patented technology, and the pump uses imported oil seals to control the runout of the shaft seal to ≤0.02mm, so there is no oil leakage at the oil seal. ZJ type Roots vacuum pump, due to the use of CNC machining center processing, "O" ring seals are used between the pump body and side cover, side cover and end cover, cylindrical pin positioning, good parts interchangeability, easy maintenance, the pump adopts The structural design of one air inlet and three exhaust ports is convenient for users to install and use. The Roots pump cannot be used alone. It can only be used with a backing pump in series. You can choose a screw pump, an oil seal pump, or a liquid ring pump as a backing pump. It is worth mentioning that when you choose a screw pump or a liquid ring pump as a backing pump, , especially suitable for situations where a large amount of suspicious gases are extracted.
