The hydraulic wrench is small and light, flexible to use, and has a wide range of applications. So, before using a hydraulic wrench, what should be paid attention to?
1. First determine whether to loosen it or whether the lock nut is pressed or unscrewed by (tōng guò) the locking screw, take out the square drive shaft for left-right reversal, install the square drive shaft locator, pull down the reaction arm to lock it The device, install the reaction arm according to the appropriate orientation, loosen and lock the direction of the square axis
2. Connect the pump station. Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is a professional bolt tightening tool that is powered by hydraulic pressure and provides high torque output. It is used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Connect the high-pressure outlet (A) of the pump with the high-pressure inlet (H) of the hydraulic (hydraulic) wrench, and the low-pressure outlet (B) of the pump and the low-pressure inlet (R) of the hydraulic (hydraulic) wrench with high-pressure tubing respectively. When connecting, the quick connector on the tubing should be inserted to the end, and then tighten the fixed nut by hand
3. Check carefully whether the pipe joints are connected reliably and whether there is oil in the pump
4. Connect the power plug of the pump well, and it is strictly forbidden to run without oil!
