The work that needs to be done when using hydraulic wrench
source:Industry News release time:2022-03-07 Article author:Rosit Popular:Air band saw
Hydraulic wrenches are divided into driving hydraulic wrenches and hollow hydraulic wrenches. Their pollution sources come from three parts, external infection, internal pollutants and pollutants generated by the hydraulic wrench system, because when using hydraulic wrenches, Pay attention to the following points.
1. Install the hydraulic wrench, and screw the oil return valve rod clockwise before use
2. The working oil of the hydraulic puller is preferably anti-wear hydraulic oil, and the working oil must be clean.
3. According to the size of the preload nut, select the inner hexagon socket.
4. Insert the high-pressure and low-pressure hoses with quick connectors into the connection between the wrench and the reversing valve
5. Tilt the piston starting rod back and forth to move forward steadily, and the claw hook retreats accordingly to pull out the object to be pulled.
6. The angle of the connecting rod of the wrench should be controlled within the range of the angle calibrated by the reaction rod.
7. Suppression
8. After the preload is over, put the handle of the reversing valve in the middle position to make the pressure return to zero.
9. After removing the quick connector, the exposed part of the connector must be covered with a plastic cover;
