3 Signs Of Hydraulic Pump Cavitation

Hydraulic pumps play a critical role in powering many pieces of heavy machinery. Without access to a functional hydraulic pump, these machines wouldn't function properly. If you rely on a hydraulic-powered machine to complete vital tasks each day, then proper maintenance of the hydraulic pump is essential.

Cavitation (which can be defined as a pump's inability to draw in enough oil during normal use) is a problem that can plague hydraulic pumps. Being able to spot the signs of cavitation early will allow you to replace malfunctioning parts before the entire pump is compromised.

Here are three signs to look for when trying to determine if cavitation is a problem for your hyudralic pump in the future.

1. Increased noise production.

When functioning properly, a hydraulic pump should run smoothly and quietly. If you notice your hydraulic-powered machine is running louder than normal, cavitation could be to blame. As the pump has to work increasingly harder to draw in enough oil for proper function, the pump vibrates more than it normally would.

The increased vibration can result in loud knocking or banging noises when your machine is in use. If you hear these loud noises while operating your hydraulic machinery, check your pump for cavitation.

2. Increased heat during use.

The oil that is drawn into the hydraulic pump serves a variety of purposes. One of the main functions of this oil is to help disperse heat that is generated with the moving parts of the pump create friction.

When a hydraulic pump is suffering from cavitation, the lack of available oil could cause the pump to run hot. Be sure that you regularly check temperatures around the pump's shaft and front bearing during use. If these temperatures start to climb, then a lack of oil caused by cavitation could be to blame.

3. Inability to maintain proper pressure.

Hydraulic pumps work to generate pressure by exerting force on hydrualic fluids. This pressure powers the machinery that relies on hydrualic pumps for proper function. When a pump is suffering from cavitation, it will be impossible for the pump to maintain proper pressure over an extended period of time.

This could result in erratic function of your machinery. Be sure to check your pump for cavitation if you start to notice sudden fluctuations in hydraulic pressure when using your hydraulic-powered machines in the future.

Being able to spot common signs of cavitation will help you better maintain your hydraulic pumps in the future. Contact a company, like Quad Fluid Dynamics Inc, for more help.
