Precautions for the use of hollow hydraulic wrench
source:Industry News release time:2022-03-22 Article author:Rosit Popular:Air band saw
Hollow hydraulic wrench is a kind of hydraulic wrench, and it is also one of the main sales of Quecher Hydraulic. This product has a wide range of applications. The hollow hydraulic wrench is thin in thickness and is especially suitable for places where the space is relatively narrow, so it is used in many industries and is also very practical. There are also many points of attention in the operation of hollow hydraulic wrenches.
The precautions for hollow hydraulic wrench are as follows:
1. In order to avoid personal injury and possible equipment damage, ensure that each hydraulic component can withstand a working pressure of 70MPa (700bar) In order to avoid personal injury and possible equipment damage, ensure that each hydraulic component can withstand 70MPa (700bar) work pressure.
2. Do not exceed the rated load of the equipment Minimize the risk of overloading; use a pressure gauge in the system to display the operating load. The pressure gauge is a window into what's going on within the system. When using a hydraulic wrench, do not exceed its maximum allowable value.
3. Avoid damaging the hydraulic oil pipe Serious bending and winding of the hydraulic oil pipe should be avoided during use. Using bent or twisted tubing will create excessive back pressure. Severe bends and tangles cause internal damage to the tubing, resulting in premature failure. Do not drop or press heavy objects onto the tubing. Severe impact can cause damage to the metal wire inside the oil pipe, and the damaged oil pipe may rupture when pressurized.
Correct operation steps can improve the service life of hollow hydraulic wrench:
1. Install the hydraulic wrench and tighten 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
9. After removing the quick connector, the exposed part of the connector must be covered with a plastic cover;
