Instructions for safe operation of using hollow wrench.Air impact wrench

　　Prepare

　　1. Determine whether to loosen or loosen the locking screw, remove the upper and lower steering shafts, install the rotating shaft locator, drag down the reaction force locking device, install the reaction force arm in the proper position, loosen and lock the square. The working direction of the axis.

　　2. Connect the pump room

　　The high pressure inlet and outlet (a) of the pump are connected with the high pressure channel (h) of the hollow wrench, and the low voltage inlet and outlet (b) of the pump are respectively connected with the low voltage channel (r) of the hydraulic press wrench according to the hydraulic oil pipe. When connecting, insert the quick connector on the oil pipe into the top, and then tighten the fixed nut by hand.

　　3. Carefully check whether the high-pressure hose can be connected to a reliable one, and whether there is organic oil in the pump.

　　4. Connect the power cord plug of the pump.

　　Do not operate the diaphragm vacuum pump!

　　test run

　　◆ Place the wrench on free ground.

　　Turn on the main power switch of the oil pump, run the oil pump, and check whether the oil pump is working normally.

　　◆Press the last button on the power switch of the wired controller, then the square shaft gradually rotates, the hollow wrench stops rotating in time, and the pressure gauge rises rapidly from 0 to the set pressure; release the button, the wrench will automatically return, repeat a few times. Back, make the wrench high speed several times, observe the rotation direction of the wrench, and make sure it is loose or locked. Put the wrench on the socket specification only if there is no abnormality.

　　operate

　　◆ Adjust the pressure

　　Press and hold the button on the power switch of the remote control with one hand, then the square shaft gradually starts to rotate, the hollow wrench does not stop rotating in time, the pressure gauge increases from 0 speed, and the other hand adjusts and decompresses the oil pump during operation valve, adjust the needle in the pressure table to the desired asset pressure.

　　◆ Loosen

　　Adjust the pressure of the pump room to the A value, determine the rotation direction of the hollow wrench as the loose position, put the wrench on the socket specification, find the reaction force support, keep it for a long time, repeat the posture of the second and third items until it is removed. down the nut.

　　◆ Lock

　　Ⅰ. Torque setting

　　, the torque can be set according to the design scheme. If there is no design torque, it is recommended to set the torque according to the data information in Table 1.

　　Ⅱ. Pump room pressure setting

　　Set the pump room pressure according to the required torque and type of wrench (refer to the instructions for use)

　　Ⅲ. Make sure that a wrench is turned into a locked position, and the wrench can be placed on the working sleeve specification and the position of the third item in the second item is continuously performed until the nut does not move.

　　warn

　　In order to prevent accidental injury and the possibility of damaging the machine and equipment, ensure that each hollow wrench hydraulic system can bear the pressure of 70 MPa.

　　Can not exceed the stable load of machinery and equipment (70Mpa)

　　The pressure gauge in the application software indicates the working load. The pressure gauge has dialog boxes that generate conditions in the system software.

　　When using the photoelectric hollow wrench hydraulic press wrench, it is not allowed to exceed its allowable large working torque.

　　Warning: Replace damaged parts with original parts as soon as possible.

　　In the application, the high pressure oil pipe should be prevented from being seriously bent and coiled. Applying bent or coiled tubing can cause excessive back pressure.

　　Do not drop or press hanging objects on the pipe. The more serious impact is likely to cause damage to the iron wire in the oil pipeline, and the oil pipeline is likely to crack during the whole process of charging.

　　In order to prevent damage and damage to machinery and equipment and life safety, do not remove the rain shield on the hollow wrench body, do not modify the wrench and accessories, and do not change the valve on the hydraulic rotary joint.
