What is the reason for the gear oil pump not being oiled?
Gear oil pump is suitable for conveying various lubricating liquids. It is a device that converts mechanical energy into hydraulic energy by a pair of gears that mesh with each other.It is widely used in the lubrication system of air compressors.The failure of the oil pump in operation is usually a decrease in oil pressure in the lubrication system, and sometimes even oil failure.So, why is the large flow gear pump not oiling? 1.The seal between the pump body and the pump cover of the large flow gear pump is not good; 2.The amount of oil in the oil tank is insufficient; 3.The oil pump parts are severely worn; 4.The direction of rotation is opposite to the specified direction; 5. The suction filter is blocked. 6. The suction pipe is not tight and the check valve is stuck. In summary, in actual work, different treatments should be performed according to specific situations.Special attention should be paid to the sealing of the oil suction pipeline and the seal between the gear oil pump body and the pump cover during maintenance.If the suction end is not well sealed, air will leak into the inlet of the oil pump, causing the large-flow gear pump to evacuate.
