Construction features and working principle of the pump:Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.It employs a pair of rotors, identical and in 8-figure with certain clearance between themin the pump housing, rotating at the same speed in opposite directions to performfunction of suction and discharge of gas. The two rotors are supported by rolling bearingsin the end covers of the pump, rotating at high speed and are kept at afixed relative position by a pair of timing gears. The end clearance between rotors andend covers are fixed by adjustable metal shims between the bearing housings and theend cover at the fixed end, which ensures one-direction expansion of the rotor whentemperature rises during its operation.Four sets of inner seals (also known as piston ring) in the two end covers prevent lube oilentering into the pump housing. The shaft seal at the front-end cover, also called asframework oil seal or shaft seal, prevents leakage of air into the pump housing.In order to reduce temperature of the pump, all models of pumps (expect the twosmallest models) are equipped with a gearbox cooler and front-end cover cooler.Power is transmitted through a coupling or V-belt from the motor to the driving shaft ofthe pump and then through synchronizing gears to the driven shaftProduct's ApplicationProduct DisplayCompany PowerFAQ1.Q:Are you a manufacturer or trading company?
