The operation and use of the hydraulic wrench tutorial is divided into six parts: inspection of the hydraulic torque wrench, connection of the hydraulic wrench system, idling the hydraulic torque wrench, determining the direction of the drive shaft, adjusting the hydraulic pump pressure to the specified pressure and the removal of the hydraulic wrench system. So how much is the hydraulic wrench? First understand the hydraulic wrench operation and use of the tutorial.

First, the inspection of hydraulic torque wrench

1) Check whether the rated working pressure of the hydraulic components and supporting components matches the pressure of the hydraulic pump (maximum pressure).

2) Check that the hydraulic tubing is not wound, confirm that the connection of the square drive shaft and its lock is safe and reliable, and ensure that all joints,elbows and rotary joints are not deformed or damaged.

3) Check whether the hydraulic oil grade and dosage in the hydraulic pump tank meet the requirements of the manual.

Second, connect the hydraulic wrench system

1) Connect the hydraulic pump station with the hydraulic wrench: One end of the hydraulic pipe is a threaded joint, the other end is an internal threaded joint,with two hydraulic pipes connected with the hydraulic wrench, the pipe threaded joint is connected with the hydraulic wrench internal threaded joint, the internal threaded joint is connected with the external threaded joint, the other end of the hydraulic pipe is connected with the hydraulic pump, and the internal and external threaded joint is connected to each other (the hydraulic pump connector must be a matching pair of joints). After connection, check whether the tubing joint is tight.

2) Connect the power supply and start the hydraulic pump.

Third, idling hydraulic wrench, determine the direction of the drive shaft

1) Empty operation: the remote control switch "oil" pressure does not let go, wrench into the oil; At this time, the wrench starts to turn, and when the wrench "snap"is heard, the wrench is in place to stop rotating; At this time, let go again, that is, the oil return position, when you hear the wrench "snap" again, it means that the wrench reset is complete. Repeat the above action, so that the wrench empty operation 3 ~ 5 circles, observe the wrench rotation is abnormal, normal operation can start to work.

2) Determine the direction of the drive shaft: Observe the face of the bolt, rotate clockwise to tighten the direction, rotate counterclockwise to loosen the bolt.

4. Adjust the hydraulic pump pressure to the specified pressure

1) Turn the pressure regulating nut on the butterfly bolt on the hydraulic pump counterclockwise to loosen the pressure regulating valve.

2) Loosen the rotating handle counterclockwise until it can no longer be loosened, then the oil pressure gauge value is zero.

3) Press the start button to start the motor.

4) Hold down the operation button and turn the pressure regulator clockwise to raise the hydraulic pressure.

5) When adjusting the pressure, the liquid pressure should be adjusted from low to high to the required value.

5. Tighten the inspection bolts

The high-strength bolt is checked by tightening method, that is, the specified torque of the high-strength bolt is tightened. If the hydraulic wrench does not rotate,the bolt is not loosened normally and the required torque is reached. If the hydraulic wrench rotates, it indicates that the bolt is loose, and the bolt torque does not reach the specified torque value. The cost of the hydraulic wrench has a lot to do with the bolts.

Six, the hydraulic wrench system disassembly

After checking the high strength bolts, remove the hydraulic wrench system.

1) Hold down the operation button and do not relax. At the same time, turn the rotating handle on the butterfly bolt on the hydraulic pump counterclockwise to loosen the pressure regulator. When there is no pressure at the hydraulic pump station, release the operation button.

2) Turn off the power.

3) Loosen the tubing connector, and tighten the two ends of the tubing with internal and external thread joints to prevent the joint from entering debris. Tighten seal cover of joint on hydraulic pump station.

4) Clean the residual hydraulic oil at the connector of the hydraulic wrench and put the hydraulic wrench into the toolbox.
