The screw pump belongs to the volumetric rotor pump, which absorbs and discharges the liquid by the displacement of several sealing cavities formed by the screw tooth profile and the pump sleeve. There is no theoretical leakage channel between the two adjacent sealing cavities in the screw pump, which is called the strictly sealed screw pump, on the contrary, it is not strictly sealed screw pump.

The high -viscosity pump can transport high concentrations, without particles or medium containing some small particles. This is difficult to achieve other pumps, but it is very easy for high viscosity pumps.

The circular arc gear is in continuous contact between the two meshing tooth profiles, which will not produce oil trapping phenomenon, which completely solves the phenomenon of vibration, noise and bearing load increase of involute gear pump due to oil trapping phenomenon.

Stainless steel gear pumps are mainly used in water systems with low flow and high lift, such as drinking water supply system, pressure boiler water supply system, high purity water purification system, as well as washing and spraying processes in pharmaceutical, food, fine chemical, paper and other industries.

Before the first start-up of the screw pump, the mud collection pool and mud pipeline should be cleaned to prevent stones, cement blocks and other metal objects from falling during construction from entering the crusher or pump. Usually, you should open the inlet and outlet valve before starting and make sure that the pipeline is unobstructed.

Fault Analysis of Gear Oil pump.1. Oil seal wear and glue seal aging.2. Wear of oil pump shell.3. Wear of internal parts of oil pump.It is not suitable to work under over-rated pressure, which will overload the prime mover, increase the bearing load, deform the working parts, increase friction and leakage, and cause blockage in serious cases.
