AI Technical Summary
When the system pressure of an existing gear oil pump exceeds the rated design pressure, it can easily lead to wear on the gear meshing surface, bearing deformation, leakage, and increased hydraulic oil temperature, affecting the normal operation and lifespan of the equipment.
Design an integrated overflow valve gear oil pump. By integrating an overflow valve structure on the back of the gear pump, pressure is limited by the valve plug and valve core spring to avoid excessive pressure in the pump chamber. The pump is easy to move with casters and a push handle, and a drain port is provided to remove residual liquid.
It effectively prevents gears and other components from being damaged by overpressure, extends equipment life, reduces leakage and pollution, and improves equipment reliability and flexibility.
