The removal of hydraulic cylinder of pipe bending machine
First of all, you should know the hydraulic cylinder of the pipe bending machine first, before deciding to disassemble, should survey first.Prepare for later assembly.Respectively is the oil mouth position, the placement size.
Then you can remove the bottom, the top, and the guide sleeve.Remove the piston rod from the cylinder.Let's take the piston down.The piston is usually threaded, but there will be a check screw. Remove the check screw first.Finally remove the sealing ring.
When a hydraulic system has more than one hydraulic cylinder, it is necessary to connect a valve at the pump outlet, and ensure that each hydraulic cylinder can do normal things, or when some do not, the whole is quiet.
It is better to install an electromagnetic overflow valve. This valve can control the pressure of your entire system, and it can open the pressure relief when the pressure of the cylinder does not rise above the nominal pressure. |
