In most hydraulic fluid power applications there are essentially two ways to get the required power output: high flow at low pressure; and low flow at high pressure. This is of course because power is a product of flow and pressure; increase pressure and you can reduce flow proportionately but still get the same power output. For example, 100 liters/minute … Read more

As explained in a previous blog post, in the hydraulics world the ability to read a schematic diagram, and the ability to troubleshoot effectively are often considered to go together, ‘hand in glove’. But this is not the case. The ability to read a hydraulic schematic is merely an indication of a certain level of system knowledge. And this … Read more

Some time ago I recorded a simulation video which explains what happens when the piston-seal on a double-acting cylinder leaks, and it becomes a displacement cylinder.

After watching the video, Larry from Canada sent me this in response:

“I enjoyed your video about cylinder drift not being caused by oil leaking past the seals. But I have to ask … Read more
