In the course of the use of hydraulic wrench pump failure than hydraulic wrench to be more, so today mainly talk about the pump troubleshooting. If the oil table shows the pressure rise but the wrench does not work may be loose joints failure or solenoid valve failure, you can tighten the joints or replace the parts with a spare parts or solenoid valve try again. If the oil table shows no pressure to first check whether the oil sheet connection is loose or oil table failure, if the oil table no problem Look at the solenoid valve or valve is invalid, if this is not the problem that is certainly the pump thrown a leak, need Contact the supplier to solve.

If the fuel pump boosted or can not rise to 10000psi to exclude the lack of power supply must be inside the wrench or pump solenoid valve, valve or pump inside the leakage of the need to check whether the seal ring wear and tear. If the pump does not turn on the motor after the start, open the electric control box to view or re-connect the loose line to be still no recovery need to troubleshoot the motor is damaged. If the pump motor rolling slowly invalid, remove the voltage and pressure to meet the requirements if there is no problem is the radiator channel blockage, cleaning can be resolved.

There is a wind power scene often encountered the fault is the pump temperature overheating, remove the power undervoltage control the rest may be a manual operation, the operator in the cylinder to reach the maximum stroke is still on the forward button, which will make A large amount of hydraulic oil passes through the holes in the safety valve to cause a fever. Whether the operator releases the button when the quick release lever does not reach the front and presses the forward button.
