Hydraulic pulleris an ideal new tool to replace traditional puller. It has the advantages of easy operation, labor saving, and not limited by the site. However, the use of hydraulic motors for a long time will inevitably appear damage, hydraulic motors broken how to repair, the following comprehensive some common faults and solutions of hydraulic motors.

Fault 1: The hydraulic pump has no diameter after adding oil

Solution: There are two reasons for this failure, the first is that the air entered when refueling, and did not discharge clean or no air at all. The second is that some sealing rings are not installed during repair, leading to internal leakage. Only if the above two possible causes are excluded, the problem should be able to solve.

Fault 2: How to repair oil leakage of hydraulic pump

Solution: More than 90% of the oil leakage problem is because the rubber sealing ring inside the gearbox for a long time by the alternate change of cold and warm temperature, resulting in the loss of a large number of plasticizers and softeners in the sealing ring, there is a problem of corrosion, aging and hardening, the first is oil seepage, slowly began to drip phenomenon, a long time the sealing ring appears to break, it is recommended to change a sealing ring.

Fault 3: How to do if the hydraulic puller top rod does not return

Solution: After the valve conversion, the automatic retracting of the ejector rod requires pressure to press it back.

Fault four: The reason why the hydraulic pump has no pressure

Solution: There are three reasons, 1. Insufficient oil level. 2. If there is a leak, check the pipe and junction. 3. The pressurized one-way cut is broken. The above reasons can be checked one by one.

In order to maintain the service life of the hydraulic pump, the operator should read the manual carefully, the following is the use of the hydraulic pump and precautions.

1. Tighten the oil return valve stem clockwise before use;

2. adjust the hook claw seat to grasp the object pulled by the hook;

3. Lift the piston starting rod back and forth to move forward smoothly, and the grappling hook will retreat accordingly to pull out the object being pulled;

4. If the extension distance of the piston starting rod is greater than the effective distance of the hydraulic pulling piston starting rod, it is necessary to stop when the extension distance is connected to the maximum effective distance, loosen the oil return valve stem, and let the piston starting rod withdraw, and repeat 1-3 steps again after adjustment until it is pulled out;

5. to loosen the oil return valve stem, just gently loosen the oil return valve in the counterclockwise direction. The piston starting rod slowly retracts under the action of the spring;

6. before use must estimate the force required to be pulled out of the object, choose a suitable pull, do not use overweight to prevent damage;

7. hydraulic oil to anti-wear hydraulic oil is appropriate, the working oil must be clean.
