Hydraulic ram repair
Thread Content
One of my 50T hydraulic ram will not return to its original position after use; is the circuit blocked? Could some expert send me a structural diagram so I can study it?*
I agree with you; check if the return oil line is blocked!
It was opened and inspected this morning, and no obvious problems were found. It would be great to have a detailed schematic diagram.
After it was installed as before, the ram will not move – what could be the reason? Are check valves good?
Working principle: The hydraulic ram moves forward directly through hydraulic pressure, so the push rod itself does not rotate. The claw seat can be adjusted forward and backward along the thread; during operation, simply swing the handle back and forth slightly, which causes the hydraulic actuation rod to move forward and the claw to move backward accordingly, thereby pulling the object being held out. Analysis of common problems in hydraulic ram units with threaded screws in traditional hollow cylinders: ◇ Slipping of the clamping jaws during operation, leading to safety accidents ◇ Unbalanced loading on the ram, causing the screw to bend and get stuck inside the hollow cylinder, resulting in a difficult situation ◇ Unbalanced loading on the ram, leading to the breakage or straightening of the screw and clamping jaws, which in turn causes safety accidents ◇ Too short a stroke for the cylinder, requiring multiple positioning attempts to complete the task, thereby increasing the workload unnecessarily
A hydraulic ram is essentially a combination of a jack and a mechanical ram; possible causes include leakage from the piston of the hydraulic cylinder (bending or wear)； One-way valve leakage or sticking ； Lack of oil or insufficient oil viscosity.
