　　Proper application of hydraulic wrenches, I have produced the following hydraulic wrenches for you to use in a complete set:

　　1. The function of the power switch button of the wired controller: press and hold the (RUN) button, the cylinder will advance; release the button, the cylinder will be calibrated. Press and hold the (terminate) button to stop the petrol pump.

　　2. Before starting the hydraulic wrench type pump station, first open (unscrew) the pressure maintenance valve, then turn on the switching power supply (ON), and check whether the system software hydraulic wrench type pump station project staff can be all normal; then start the line Press the button of the controller several times, work for a few minutes, and adjust the pressure to the preset student pressure value for the required time. The rated value of the staff's office environment pressure is 70Mpa.

　　3. When adjusting the pressure, press and hold the button of the remote control. When the hydraulic wrench breaks, quickly release the oil cylinder and return to its position. The hydraulic wrench stops turning over and the pressure gauge rises rapidly from 0. On the other hand, slowly move the pressure valve upward. . And can be locked with a lock nut.

　　When emptying the actual operation, put the hydraulic wrench on the ground, press the (operation) button, the wrench will gradually turn over, if you hear the hydraulic wrench crack, the hydraulic wrench will be turned over at an appropriate position; now release the button, the wrench will be calibrated. Calibration is in progress when you hear the hydraulic wrench break again. That is: the operation promotion module is released, and the calibration module is released. Repeatedly work in the circulation system to check whether the overturn of the hydraulic wrench is abnormal. The hydraulic wrench can be placed on the nut to work.

　　Loosen the nut: The pressure of the hydraulic wrench type pump station is A (70mpa), the hydraulic wrench is turned to the disassembly position, and the reaction force fulcrum is prepared in advance. If you can't move, then use anti-rust treatment, if the nut is still moving, you need to use a higher torque wrench.

　　6. Clamping the screw cap: Check the torque list during work. We set the pressure of a hydraulic wrench-type pump station, determine that the adjustable wrench is turned into the clamping position, find the key pivot point of the reaction force, rely on stability, and repeat the problem to carry out selection. The success or failure of the oil cylinder controls the circulation system until the screw cap does not move and is interrupted.

　　7. When the hydraulic wrench is terminated, the program should be closed immediately.

　　Figure 8. Disconnect the switch power when finished, press and hold the valve to remove the residual pressure in the system software, fully open the pressure reducing valve, and then open the oil pipeline.
