The hydraulic pump "noise", was actually the reason

The abnormal sound produced by the mechanical equipment in the work. We know that the equipment will sound it is a normal phenomenon in the operation time, but also there will be some abnormal sound to confuse the public, these voices are often because of equipment malfunction and the formation of.

A normal machine work should be powerful, loud, and when there is a problem, sometimes with a special voice warning function, hydraulic pump is one of the commonly used hydraulic components, there will be a strange phenomenon, which requires us to find the problem source, a solution. Now we have to understand some of the common hydraulic pump noise problems and solutions.

Common problems and solutions of noise:

The viscosity of hydraulic oil is too large, so that the self-priming capacity of the pump is reduced and the volumetric efficiency is decreased.

Processing method: choose the appropriate viscosity of hydraulic oil, if the oil temperature is too low, should open the heating.

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

Processing method: according to the provisions of the oil, cleaning filter, clear the intake pipe; check and tighten the connecting screw into the oil pipe section.

There is air in the oil pump; this fault usually occurs when a new pump is installed; when a new pump is started, the oil should be added to the pump, which will play a lubrication role in the bearing, plunger and cylinder of the pump.

Treatment method: when the pump is running, open the fuel pump port, so that the pump air from the fuel outlet.

Improper installation of oil pump and motor; that is to say, the concentricity of the pump shaft and the motor shaft is inconsistent, so that the oil pump bearing is affected by the radial force.

Processing method: check the concentricity between the adjusting oil pump and the motor installation.

The development of science is to ask questions, solve problems, mechanical engineering problems, we need to solve in time, don't look at the hydraulic pump is small, hidden in one of the science and technology is a lot, we need to really understand it, can change the resistance as the driving force, constantly solve emergencies.
