Roots pump is a kind of vacuum pump without internal compression. It is a vacuum pump that realizes air extraction by moving gas under the pushing action of synchronous and reverse rotation of a pair of "8" shaped rotors in the pump cavity. Generally, the pumping rate is large and the power of the motor is small, so the front pump is required to pre pump. After the front pump reaches the specified vacuum degree, start the roots vacuum pump to improve the pumping speed and vacuum degree. Its structure and working principle are similar to roots blower. During operation, its suction is connected with the evacuated container or the main pump of vacuum system. There is no contact between rotors of Roots vacuum pump and between rotors and pump casing.
The running parts in the pump have no friction, no lubrication, and there is no oil in the pump cavity, so a clean vacuum can be obtained.
two leaf involute cycloid profile, high-precision machining to ensure smooth and quiet operation.
the gas in the pump chamber flows vertically, which is conducive to the discharge of dust and condensate in the pumped gas.
. The high-strength rotor with complete symmetry and precise dynamic balance operates stably and reliably.
high precision gear, imported bearing, low vibration and noise.
the new omni-directional three-dimensional water-cooling jacket design can effectively cool the pump body and greatly prolong the service life of the pump.
the overflow surface can be plated with shackles, Hastelloy and PTFE, which can adapt to corrosive environments with different strengths.
it is convenient to form roots vacuum unit with liquid ring vacuum pump, rotary vane vacuum pump and dry vacuum pump.
