Solutions for noise in hydraulic pumping stations

When we use the convenience brought to us by the hydraulic pump station, we often encounter a problem, that is, the noise phenomenon occurs during the use of the hydraulic pump station. The following is an analysis of the solution to the noise of the hydraulic pump station.

    1. It may be that the suction pipe and the filter are blocked or the filter capacity is small. The filter should be cleaned to make the suction pipe unobstructed, and the filter should be selected correctly.

    2. There are air leaks or air bubbles in the oil suction pipe seal. The solution is to add some oil to the connection or the seal. If the noise is reduced, tighten the joint or replace the sealing ring; the oil return pipe should be below the oil level, and the oil suction Although there must be a certain distance.

    3. If the oil level is low or the oil temperature is low, and the viscosity is high, the solution is to add oil and heat the oil to an appropriate temperature.

    4. The pump bearing is damaged. If it is found that the leakage oil pipes of several plunger pumps are connected in parallel to a main pipe of the same diameter before connecting to the oil tank, or the oil drain pipe of the plunger pump is connected to the main oil return pipe, it should be corrected. Connect a pressure gauge to the pump leakage port to check the pressure in the pump body.

    5. It is also possible that the pump and the coupling are not concentric. If they are not concentric, the pump and the coupling should be adjusted to be concentric.

    The above are the reasons and solutions for the noise during the use of the hydraulic pump station. I hope everyone can help after reading the above statement.
