Improve the performance of large flow gear pumps

Publish: Browse:
Application range of large-flow gear pumps : used as transmission and booster pumps in oil delivery systems; used as fuel pumps for delivery, pressurization and injection in fuel systems; as lubricant pumps in all industrial fields use.
Structural features of large flow gear pump: This series of gear pump is mainly composed of gear, shaft, pump body, safety valve and shaft end seal. The gear has high hardness and strength after heat treatment, and it is installed in the replaceable sleeve to run with the shaft. The lubrication of all parts in the pump is automatically achieved by using the output medium when the pump is working. The pump has a well-designed drain and oil return tank, which is the smallest torque force that the gear can bear during work, so the bearing load is small, the wear is small, and the pump efficiency is high.
The pump is equipped with a safety valve for overload protection. The full return pressure of the safety valve is 1.5 times the rated exhaust pressure of the pump. It can also be adjusted according to actual needs within the allowable discharge pressure range. However, please note that this safety valve cannot be used for long-term operation of the pressure reducing valve, and can be separately installed on the pipeline when needed. Looking from the extended end of the main shaft to the pump, it rotates clockwise.

Due to the structural limitation of a fixed displacement, a large-flow gear pump is generally considered to be used only as a constant-flow hydraulic source. However, the accessory and threaded combination valve scheme is effective for improving its function, reducing system cost, and improving system reliability. Therefore, the performance of gear oil pumps can approach the expensive and complicated plunger pumps.

Large-flow gear pumps, various series of gear pumps, couplings produced, complete specifications, advanced technology, sophisticated production equipment, strong technical force, complete testing equipment, quality in line with relevant standards issued by the state and ministries, and reliable performance.
