How much is a hydraulic wrench? Hydraulic wrench operation method and maintenance method

In the sales market of hydraulic wrenches in China, there has been great development and competition is fierce. The hydraulic wrench is an important tool for the installation and disassembly of large size bolts. It is mainly used for large mechanical equipment or mechanical equipment with strong vibration. Here we take a look at how much the hydraulic wrench? Hydraulic wrench operation method and maintenance method.

　　 Hydraulic wrench operation method

1, according to the size of the pre-tightening nut to match the appropriate inner hexagonal sleeve

2, according to the tightness of the nut, to combine the ratchet.

3. Put the quick connector of the high and low pressure hoses into the spanner and the reversing valve. After confirming that the connector is completely connected, correct the dust-proof ring of the quick connector so that the lock will not move. Prevent leakage when the hydraulic wrench works.

4. Put the reaction arm on the inner hexagonal support sleeve or other safety position. Quickly press the type lock to position the fine adjustment reaction arm on the fastening fulcrum. High-strength support pads, Thyssen hydraulic and durable wear . The size of the corner must be controlled within the standard range of the reaction arm.

5, when using the Hydraulic Pump station to suppress, we must first observe the value on the pressure gauge, the pressure gauge is (MPa) as a unit, by reading the value of the pressure gauge, we can get its torque value accordingly.

6, after completion, the pressure back to zero.

7, the final step is to remove the high and low pressure hoses, pull out the connector cover dust cap.

　　 Hydraulic wrench maintenance method

1. During the handling and use of the hydraulic wrench, it is necessary to avoid throwing and hammering, and to reduce its damage as much as possible;

2. The working fluid used by the hydraulic wrench is hydraulic oil, so it cannot be replaced by medium such as alcohol or water. In addition, the used hydraulic oil must be clean and pure before it can be used;

3, in the usual use, if the wrench remains a variety of oil, should immediately wipe clean with a clean rag;

4. If the hydraulic wrench is not used for a long time, be sure to prepare it for rust prevention. Common anti-rust method is to apply Vaseline on the hydraulic wrench for anti-rust treatment, and then place it in the original box, in a dry, suitable temperature room for storage;

5, in order to prevent contamination of working fluids, so the connection to the oil pipe in the hydraulic system is replaced with a threaded plug;

6, high-pressure hose in the long-term use, it will reduce the strength, so we use for a period of time, need to use high-pressure hose replacement;

7. Before using the hydraulic wrench, it is necessary to read the instructions carefully and operate according to the requirements of the instructions to avoid accidental injury;

8, when the pre-tightening, must be strictly controlled pressure, and should not be used over-pressure.

The use of hydraulic wrenches is widely used in the construction, maintenance and repair work of shipbuilding engineering, petrochemical industry, wind power, hydropower, thermal power, mining, machinery, steel mills, rubber, pipelines and other industries. After reading the contents of the above small series for everyone, I believe that everyone now has a basic understanding of the price and operation and maintenance of hydraulic wrenches. Only by mastering the use of hydraulic wrenches and maintenance methods, can hydraulic wrenches be safely operated and found When faults occur, maintenance can be done in time.
