1. Rapid change of ambient temperature 2. Emptying, cavitation or holding pressure for a long time, resulting in seal damage and leakage of cam rotor pump unit.3. The return flow is too large, which leads to the sediment at the bottom of the suction tube side container (tower, kettle, tank, pool), which damages the seal.

High viscosity rotor pump in daily use pay attention to the preservation of electric oil pump should be placed in a dry, clean and corrosive gas-free environment. Save each part and replace the same part, when disassembling and inspecting the high viscosity rotor pump, you should save each part, and pay special attention to the flameproof surface of the flameproof part can not make its damage, including insulation gasket and casing

The rotary lobe pump is a kind of volumetric pump which can change the volume of the pump through a pair of synchronous rotating rotors, resulting in high vacuum and discharge pressure to realize fluid transportation. There are many kinds of rotor pumps, among which the most common types are stainless steel rotary lobe pump, high viscosity rotor pump and food transfer pump.

The machining quality of the stator and rotor of the cam rotor pump refers to the surface roughness of the stator cavity, the rubber straightness of the stator cavity, the bonding strength of rubber and steel sleeve, the non-leakage of the threads at both ends of the stator under the rated working pressure and the surface roughness of the rotor. whether the straightness of the rotor, whether the rotor eccentricity and cross-section circle diameter meet the design requirements, whether the rotor key layer is smooth and intact, whether the rotor connecting thread meets the standard, etc.

Stainless steel rotor pump is the use of the pump body to transport materials, there are many kinds of transport pumps, the more commonly used transport pumps are rotor pump, centrifugal pump, screw pump and so on.

Rotor pump is also called colloid pump, cam pump, three-vane pump, universal pump and so on. Rotor pump belongs to volumetric pump. It achieves the purpose of conveying fluid by means of the periodic conversion of several fixed volume conveying units in the working cavity.
