Cavitation is the term used to describe the formation of gas cavities within a liquid. In a hydraulic system, this is normally taken to mean formation of vapor bubbles within the oil. But it can also mean dissolved air coming out of solution in the oil.
Cavitation erosion occurs when gas cavities in the oil collapse (implode) under pressure, in … Read more
Here are 4 reasons why hydraulics pros rarely if ever use a hand pump when troubleshooting a hydraulic machine:
A hydraulic system is a sealed, fluid-filled system. And one that is sensitive to ingress of dirt, water and air. In addition to the contaminant ingression risk, there is always a safety … Read more
A millwright recently completed a 5-day basic hydraulics training. He plans to use his recently acquired hydraulics knowledge to check and set the relief valves in the circuit shown below, using a hand pump. Valves 04 and 06 are both relief valves (no external drains are shown). The rear section of the tandem pump 01 provides two pilot pressures: Pp1 … Read more
