Characteristics and precautions of driving hydraulic wrench
source:Industry News release time:2022-09-17 Article author:yu Popular:Air band saw
Drive hydraulic wrench, there is no limit to the height, and the support point cannot be found. This type of wrench can be used in the working conditions without limited angle space, and the range of use is wide. In order to facilitate everyone's use, Zhonghong Precision will introduce the characteristics of the driving hydraulic wrench and the precautions for use.
1. Features of driving hydraulic wrench:
1. Jinghong hydraulic wrenches are all made of aviation aluminum-titanium alloys, with a one-piece body, light weight, good toughness and long service life.
2. The working pressure is 70MPa, and it works by matching the high and low pressure of the oil pump (for specific parameters and pressure values, please consult Jinghong hydraulic wrench).
3. The reaction force arm is 360° fine-tuned to find the support point. The force arm sheath is made of titanium alloy steel, which has high strength, heat resistance and corrosion resistance.
4. The oil pipe joint that can be rotated 360°×180° has no space limitation and can be operated freely.
5. The precision ratchet is used to prevent jamming, and the accuracy is as high as ±3%.
6. 12 different specifications and models, a variety of colors are available.
7. The drive shaft is made of special material, with high strength, and it is easy to switch the direction of loosening and tightening.
Second, the use of driving hydraulic wrench matters needing attention:
1. The quick joint of the high-pressure oil pipe connection wrench must be in place, and no gaps can be left, otherwise the poor oil circuit will cause the wrench to not work, and it will also cause the pressure joint of the oil pipe to be unable to be removed smoothly;
2. When the wrench is working, make sure that the sleeve acting on the wrench matches the nut, and the reaction arm finds the support point;
3. Before the wrench is used, the drive shaft needs to be inserted into the ratchet and twisted clockwise to ensure that the pawl and the ratchet are in complete agreement;
4. When disassembling and assembling the quick joint, be sure to keep the inside and outside of the joint clean to avoid dust and sand entering the oil circuit and causing the sealing ring to wear, thereby reducing the service life of the hydraulic wrench.
