Interview with Yarbrough Hydraulics Expert Tod Pearson
On a hydraulic cylinder usually the customer finds out they won’t hold a load anymore, or they start leaking, or they have a bent rod. It’s often obvious where you can see that the rod is bent in them. That’s the most common reason a cylinder is brought in.
That the tolerances but be very tight or the cylinder will not hold. If they have too much wear inside of them, even putting new seals in it, won’t fix it if too much of the metal has worn on the inside. But, he’s the good thing is we can machine and make just about any part for any cylinder, sp if its got broken or worn parts, its no problem, we can repair them or make new ones.
If the cylinders aren’t repaired correctly they will still leak – or we say they won’t hold or they bleed down. Basically if they try to lift a load, the load will actually start drifting back down because we didn’t get a tight-enough fit on the new seal and the tolerances of the steel and the seal inside of it are not right – which can actually be a safety issue/safety problem. Or, we’ve even seen them done by other companies where when they rebuilt them. They put them back together and didn’t get them back together right, and they actually can blow the cylinder apart. And of course that means bad failure, whenever that happens.
Well after we do the complete rebuild, we pressure test each cylinder to make sure that it extends and retracts as it is supposed to and that it does not leak. We put it under pressure to test it. We do a bubble test on it as well, we actually use a compound that’s almost like a soapy compound that will bubble if there is any minor, tiny leak of some sort; it will bubble on us so we’ll know if the cylinder is sealed properly or not.
