Working principle concept of the gear pump is very simple, i.e., its most basic form is the same in the two dimensions of the gear housing in a close-fitting engagement with each other the rotation, the interior of the housing similar to "8" shape, the two gears mounted In the outer diameter of the housing on both sides of the gear and work closely with the inside of the hydraulic motor (import finishing). Material from the extruder into the two gears in the middle of the suction port of the hydraulic motor, and this space is filled with a hydraulic motor (import care), with the teeth of rotary motion along the casing of the hydraulic motor (import service) phone, and finally discharged when the two meshing. A variety of hydraulic pumps and motors are using the "sealed volume (chamber)" cyclical changes to work. Working in both the need for an auxiliary valve plate and other devices, and that "sealed volume" is divided into two separate parts high and low pressure areas. Both at work will produce the phenomenon of trapped oil and radial force imbalance, hydraulic shocks, flow pulsation and fluid leaks and some common physical phenomena. Hydraulic motor (import service) phone, hydraulic motors, hydraulic pressure from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
