The press pressure is not enough, but the rising pressure is normal
, But did not repair the bending machine, but all the same as the hydraulic it, Lv Gong automation equipment, is willing to work with you to progress! For China Automation Come on!
2, pay attention to the tubing must be completely disconnected, so you can determine if the leak, know that the cylinder is vent, or the solenoid valve inside the vent. I have also repair hydraulic equipment before.
From the tank is not also flow of oil, if the cylinder is good at this time the cylinder has been unable to move the fuel tank will not live outside the fuel injection, if a little pressure began to shabu shabu oil, that is, the tank is likely to leak inside the seal
When the exclusion of the relief valve and pump problems, began to exclude the internal leakage of the hydraulic cylinder doubt it, the method: let the machine pressure down, pressure to the workpiece pressure does not move, the demolition of the cylinder under the tubing, and then continue to press
