Product Description

Gear pump is a rotary pump that depends on the working volume change and movement formed between the pump cylinder and the meshing gear to transport liquid or pressurize it.When the gear pump works, the driving wheel rotates with the motor and drives the driven wheel to rotate. When the meshing teeth on one side of the suction chamber gradually separate, the volume of the suction chamber increases, the pressure decreases, and the liquid in the suction tube is sucked into the pump; The suction liquid is pushed to the discharge chamber by the gear in two ways in the tooth groove. After the liquid enters the discharge chamber, the teeth of the two gears continue to mesh, so that the liquid is squeezed from the discharge chamber into the discharge pipe. The driving gear and driven gear keep rotating, and the pump can continuously suck in and discharge liquid.

The pump body is equipped with a safety valve, when the discharge pressure exceeds the specified pressure, the conveying liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe. The internal gear pump is composed of a pair of internal gears meshing with each other and a crescent shaped part between them, a pump shell, etc. The function of the crescent is to separate the suction chamber from the discharge chamber. When the driving gear rotates, the local vacuum is formed at the place where the gear is off the mesh, and the liquid is sucked into the pump and filled with the teeth of the suction chamber, and then enters the discharge chamber along the inner and outer sides of the crescent piece in two ways. At the point where the teeth enter engagement, the liquid present between the teeth is squeezed into the discharge tube. Gear pump in addition to the characteristics of self-priming capacity, flow and discharge pressure independent, pump shell without suction valve and discharge valve, with simple structure, uniform flow, reliable work and other characteristics, but low efficiency, noise and vibration, easy to wear, mainly used to transport non-corrosive, no solid particles and lubrication ability of various oils, the temperature generally does not exceed 70 ℃, Such as lubricating oil, edible vegetable oil, etc. The general flow range is 0.045 ~ 30ms/h, the pressure range is 0.7-20mpa, and the working speed is 1200-4000r /min.
