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:

My wife often asks me why I still do consulting work. She wonders why I happily leave the comfort of my office to crawl all over hot and dirty hydraulic machines.
Well for one, I actually enjoy it. Two, it keeps me sharp. But perhaps most importantly, it keeps me in touch with the issues that hydraulic equipment users grapple with.
One of the things I’ve learnt ...
A colleague who works for a major hydraulic component manufacturer recently told me his company’s original equipment manufacturer (OEM) customers are demanding hydraulic components which can handle operating temperatures in excess of 110°C. And this number is not for margin of safety – it’s for continuous operation.
The trouble with this is, heat is the biggest enemy o...
Hydraulic fluid has a BIG job to do. It’s a power transmission device, a lubricant, a heat transfer medium – and even a sealant, in some hydraulic components at least. And this is why I consider the fluid to be THE most important component of a hydraulic system. And certainly not something to be purchased on price alone.
But regardless of whether the hydraulic fluid yo...
This question from one of our members is relevant to all hydraulic machine owners and users:
“What is the most effective and efficient method to diagnose internal leakage on mobile construction equipment; e.g Backhoe or Skid Steer Loader — WITHOUT the aid of diagnostic tools, such as pressure gauges and flow meters.”
It’s not a bad question. But upon de...
