Zjb-600 Roots Vacuum Pump for Electronic Coating

Pump description:

Design ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.It employs a pair of rotors, identical and in 8-determine with specific clearance in between them in the pump housing, rotating at the identical speed in reverse directions to complete perform of suction and discharge of fuel. The two rotors are supported by rolling bearings in the stop handles of the pump, rotating at higher speed and are kept at a fastened relative situation by a pair of timing gears. The finish clearance in between rotors and conclude handles are set by adjustable metallic shims in between the bearing housings and the conclude cover at the mounted finish, which ensures one-route enlargement of the rotor when temperature rises for the duration of its procedure.

4 sets of internal seals (also acknowledged as piston ring) in the two conclude addresses avoid lube oil coming into into the pump housing. The shaft seal at the front-stop include, also called as framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.

In buy to decrease temperature of the pump, all models of pumps (assume the two smallest designs) are geared up with a gearbox cooler and entrance-stop include cooler.

Power is transmitted by way of a coupling or V-belt from the motor to the driving shaft of the pump and then by means of synchronizing gears to the driven shaft

The main  advantage  of Roots  vacuum pump  is that  it can  operate  with high  pumping speed under  reduce suction  pressures, nonetheless,  has to  be backed by  a backing  pump.Under  regular working problems, it is  permissible to not add  by-pass pipes.Roots vacuum pump should not run with a higher-pressure  distinction than allowable,otherwise  overheating   and   overload  will   cause  damage   of  Roots   vacuum  pump.
Therefore, appropriate backing pump and needed protection gadgets should be considered.Oil sealed mechanical  pump is usually  chosen as   the fore   vacuum   pump.  Other   types   of backing   pumps   may   be   used   where    their requirement for supreme vacuum is not too  strict. Particularly, when gas  pumped that contains large amount of  vapor, h2o-ring vacuum pump  maybe   an  ideal   option  though   ultimate  vacuum achieved is on the lower side.
