Hydraulic torque wrench operation is powered by a hydraulic pump, which is in turn runs using either electric power or pneumatic pressure. Hydraulic torque wrenches operate at high pressure (up to 10,000 PSI) and can produce torque outputs over 50,000 ft./lbs. These are very precise tools, with an accuracy range of plus or minus three percent and a repeatability of plus or minus one percent. These are industrial-strength wrenches that can apply huge torque to large bolt heads. You will find them working in power plants, pipelines and steel mills. But because of their extreme pressure levels and torque output, it is important for tool operators to understand how to use these wrenches correctly and safely.
How to choose hydraulic torque wrench:
1.Drive type hydraulic wrench is usually selected
2.Limited use of space, the choice of hollow hydraulic wrench
3.Trial space is particularly limited, the choice of ultra-thin hydraulic wrench
4.If the bolt is too long, choose bolt stretcher

1. Inspection Before connecting the system, visually inspect all components-hoses, fittings, tools, and pumps-for abnormal wear, cracks, burns, or damage.
2. Documentation Ensure that the operator has the correct pressure and torque chart for the selected tool, as well as the updated calibration certificate for the tool and the pump pressure gauge.
3. Appropriate power Make sure that the torque pump has proper power. For air pumps, this means ensuring the correct hose diameter size and the correct PSI and CFM input for the pump. For electric pumps, you need to use heavy-duty extension cords to provide adequate and sufficient current and voltage.

4. Hydraulic accessories Next in our list of hydraulic torque wrench operating tips: make sure that the hydraulic fittings are fully connected to the tool and pump hoses
5. Socket The socket must be an impact socket in good condition with no wear on the input or output side of the socket.
6. Self-check This is a critical security measure. Tool operators must be completely focused on using their tools without being distracted.
7. Connect When setting the pressure torque output on the pump, make sure that the system is fully connected and not on the application.
8. Stall When applying torque on the application, make sure that the operator completely stops the tool before retracting/releasing the pump pressure suspension controller.
9. Final progress When the tool is completely stopped, make sure that the operator applies the last advance of the tool to ensure that the bolt is fully tightened to specification before moving to the next bolt.
10. Shut down When removing the tool from the bolt, the operator should completely close the pendant switch on the pump (electric or pneumatic). Finally, it is important to ensure that your hydraulic torque wrench is properly calibrated to ensure safe and accurate measurements.
