Hydraulic Torque Wrench pumps are widely used in various industries to provide precise and reliable torque output. However, sometimes the pump may encounter problems that prevent it from working normally. It is important to be familiar with the common troubleshooting methods to quickly identify and solve these issues.

Hydraulic Torque Wrench Pumps

One common issue is when the oil gauge indicates an increase in pressure, but the wrench does not work. In this case, check if the connector or solenoid valve is loose or invalid. Tighten or replace them as necessary. If the oil gauge shows no pressure, check the oil gauge connection, solenoid valve, or Hydraulic directional valve. If none of these components are the problem, contact a dealer for assistance because there may be a leakage from the hydraulic oil pump.

Electric oil pumps can also experience insufficient pressure, which can be caused by leaks in the high-power hydraulic wrench, solenoid valve, hydraulic directional valve, or pump. Check the sealing ring of each component to determine the issue. If the motor does not rotate after operation, check the electrical control cabinet or wiring connections. A damaged motor may also be the cause.

If the motor rotates slowly or fails, ensure that the standard air pressure is correct and unclog the safety channel of the heat pipe radiator if it's blocked. Overheating of the pump due to undervoltage protection is another common issue. This can be caused by manual operation where the staff presses the forward button during a large stroke arrangement in the Hydraulic Cylinder resulting in gear oil burning through the small hole in the valve.

In summary, knowing how to troubleshoot Hydraulic torque wrench pumps can save time and money. Always take proper precautions and follow safety guidelines when performing any maintenance or repairs on the pump to avoid injury or damage to the equipment or surroundings.
