What should I do if the high pressure of the gantry shear cylinder does not work?

solutions to the problem that the pressure cylinder of gantry shears does not work when it is lowered to high pressure:

1. The travel switch of patented multi-knife gantry shears is out of order, so repair the stop iron and travel switch, or replace the travel switch.

2. The patented multi-blade gantry shear oil pump can't build up pressure. Repair the oil pump. If the oil pump is damaged, replace it with a new one.

3. If there is a big leakage or failure of the system or valves, check all the oil leaks, and then check whether the electromagnetic reversing valves are reversing and whether the pressure regulating valves are working normally.
