Hydraulic pump emit strange sound source where to find

A normal machine should work is powerful, loud voice, and when there is a problem, sometimes with a special sound to warn the effect, the hydraulic pump is commonly used hydraulic components, there will be a strange sound phenomenon, which requires us to find the source of the problem, give the solution. Now let's look at some common problems and solutions to hydraulic pump noise.

Common Noise Problems and Solutions:

There is air in the oil pump memory; This fault is generally when a new pump is installed. When a new pump is opened, oil should be added to the pump to lubricate the bearings, plunger and cylinder block of the pump.

Treatment method: Open the oil pump refueling port when the pump is running, so that the air in the pump is discharged from the refueling port.

The viscosity of hydraulic oil is too large; The self-priming capacity of the pump is reduced and the volumetric efficiency is reduced.

Treatment method: choose hydraulic oil with appropriate viscosity, if the oil temperature is too low, it should be heated.

The oil level of the tank is too low; The blockage of the suction pipe makes the suction resistance of the pump become larger, resulting in the suction of the pump or the leakage of the oil inlet pipe section, and the pump absorbs the air.

Treatment method: add enough oil according to the provisions; Clean the filter, dredge the intake pipe; Check and tighten the connecting screws of the inlet pipe section.

Improper installation of oil pump and motor; That is to say, the concentricity of the pump shaft and the motor shaft is not consistent, so that the radial force of the oil pump bearing produces noise.

Treatment: check and adjust the concentricity of oil pump and motor installation.

The development of science is to constantly put forward problems, solve problems, construction machinery problems, but also need us to solve in time, do not look at the small hydraulic pump, contained in the science and technology is also a lot of, we need to really understand it, in order to turn resistance into power, constantly solve emergencies.
