Whether the excavator is throwing soil or loading, the rotation action is essential. The rotation action of the excavator rotary actuator products hundreds of times a day can be carried out smoothly, so as to ensure the quality and efficiency of the completion of the project.

Due to the high frequency of use of the excavator rotary actuator products, we often encounter such fault phenomena as abnormal rotation sound, rotation jamming, slow and weak action during construction. Today, I share with you how to effectively deal with the fault of the rotary actuator of the excavator at the first time, so as to save time without shutdown, It can also accurately eliminate the faults of the rotary actuator of the excavator without hidden dangers.

Rotation trembling of excavator rotary actuator products

1. Check the rotary valve core of the excavator rotary actuator products to confirm whether it is stuck or the switching is poor;

2. Check whether the pressure of the overflow valve when the rotary actuator of the excavator rotates is within the normal range;

3. Check whether the excavator rotary actuator products rotary actuator and valve plate are worn;

4. Check the oil pipe and confirm the trembling part of the excavator rotary actuator products. First, determine whether it is left rotation or right rotation shaking. If it is left rotation shaking, adjust the left and right oil pipes; If the right rotation of the rotating motor trembles, there is a problem with the left oil circuit before entering the motor. If it is still left rotating and shaking, there is a problem inside the motor. Service personnel are required to test various parameters on site before judgment.

Slow or weak rotation of excavator rotary actuator products

Firstly, check whether the gear oil and hydraulic oil are sufficient. Secondly, check from the following aspects:

1. The rotary motor of the excavator rotary actuator products fails;

2. The swing pilot pressure of the excavator rotary actuator products is low;

3. Check whether the excavator rotary actuator products rotary actuator is blocked;

4. The rotation of the excavator rotary actuator is fast and slow, which may be the problem of the pilot oil circuit or the failure of the distributor.

The rotary brake of the excavator rotary actuator does not stop the vehicle

1. First check the safety relief valve on the swing motor;

2. Prevent the reverse valve of excavator rotary actuator products from jamming;

3. If the above is normal, check whether there is a problem inside the motor.

The rotary gear ring of the excavator rotary actuator leaks grease

1. First, confirm whether the rotating bearing is maintained on time according to the manufacturer's regulations (grease every 500 hours). Please operate according to the instructions;

2. Check whether the sealing strip of rotating bearing is aging;

3. Whether the added butter is of the specification specified by the manufacturer.
