Roots vacuum pump rotor is through a pair of two precision gear to achieve its relatively synchronous operation. Drive shaft coupling and the motor is coupled to. There are two major structural arrangement in the drive: one is the motor and the gear on the same side of the rotor as shown. Rotor driven by the motor drive end gear pass directly past ZJQ25-30-7.5 slurry pumps, slurry pumps this initiative torsional deformation of the rotor shaft, the gap between the two rotors will not reverse the drive shaft of the large deformation change, so that the gap between the rotor evenly during operation. The biggest drawback of this approach is that drive: a drive shaft with three bearings, increasing the difficulty of machining and assembly of the pump, disassembly and adjustment of the gear is not so; b overall structure is not symmetrical, the center of gravity tend to pump motor and gear. box side. If you have a spare pump ZJQ45-15-7.5 slurry pumps, preferably two pumps used in rotation. If the card only repair pump pump, you can add a network in the inlet ZJQ50-10-5.5 slurry pump, not too many impurities into the pump, the probability of such a card will be much smaller pump!
