Shanghai Yulong Mechanical Booster Pump

Pump description:  

Model ZJ CZPT Booster Pump, also known as a Roots pump, is a volumetric pump.It employs a pair of rotors, identical and in 8-figure with specified clearance between them in the pump housing, rotating at the identical velocity in reverse instructions to execute operate of suction and discharge of fuel. The two rotors are supported by rolling bearings in the finish handles of the pump, rotating at substantial velocity and are stored at a fastened relative position by a pair of timing gears. The finish clearance in between rotors and stop addresses are fastened by adjustable metallic shims amongst the bearing housings and the stop protect at the set conclude, which makes certain one-route growth of the rotor when temperature rises during its operation.

4 sets of inner seals (also known as piston ring) in the two finish addresses avert lube oil coming into into the pump housing. The shaft seal at the front-finish go over, also named as framework oil seal or shaft seal, helps prevent leakage of air into the pump housing.

In order to decrease temperature of the pump, all types of pumps (anticipate the two smallest designs) are outfitted with a gearbox cooler and front-finish include cooler.

Electricity is transmitted via a coupling or V-belt from the motor to the driving shaft of the pump and then through 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, nevertheless,  has to  be backed by  a backing  pump.Under  regular doing work conditions, it is  permissible to not add  by-go pipes.Roots vacuum pump must not work with a increased-pressure  difference than allowable,otherwise  overheating   and overload  will   cause  damage   of  Roots   vacuum  pump.
For that reason, correct backing pump and needed protection products have to be regarded as.Oil sealed mechanical  pump is usually chosen as   the fore   vacuum   pump.  Other   types   of backing   pumps   may   be   used   where    their requirement for ultimate vacuum is not too  strict. Particularly, when gas  pumped made up of large amount of  vapor, h2o-ring vacuum pump  maybe   an  ideal   option  though   ultimate  vacuum achieved is on the minimal facet.
