The problem of insufficient oil suction of the vane pump in the hydraulic system

In the hydraulic system, the hydraulic oil pump is the power source of the whole system, and the vane pump is a commonly used hydraulic pump. Sometimes the oil absorption of the vane pump is insufficient. The following editor will tell you the following six methods to solve the problem of insufficient oil absorption. Lets come look!

First：the oil level in the fuel tank is too low, which is also easy to solve, just fill the oil directly to the appropriate oil mark line position.

Second：the oil suction filter is clogged or the flow rate is too small. The solution is to clean the filter and replace the filter with the same flow rate.

Third：the end face of the oil distribution plate on the hydraulic oil pump is not in good contact with the screen inside the housing, and the high and low pressure chambers are colluded. This can directly repair the end face of the oil distribution plate.

Fourth：the viscosity of the oil is too high, causing the blades of the vane pump to slide inflexibly in the rotor groove. The solution is to change the hydraulic oil, and at the same time adjust various brands of hydraulic oil at any time according to the season and working conditions. The commonly used hydraulic oils are 32#, 46#, 64#, etc., depending on the actual situation and season.

Fifth：the wiring of the motor is reversed, resulting in reverse rotation, just correct the direction.

Sixth：there are trachoma inside the vane pump, and the high and low pressure chambers are connected. This can be solved by directly replacing the vane pump.

The above are the reasons and solutions for the insufficient oil suction of the 6 hydraulic system vane pumps introduced by the editor, for your reference.
