1、 Noise expansion of hydraulic motor; Analyze the reasons: 1. Fully consider that the pressure or flow of the electric hydraulic pump exceeds the rated voltage. The solution is to retrieve the causes of pressure and flow fluctuations;

2. The internal parts of hydraulic motor (such as machine tool spindle bearing, motor rotor, roller bearing, etc.) are damaged. The solution is: first Micro hydraulic cycloidal motor Dismantle, inspect, repair, and replace parts. If the motor is inspected after the replacement of new parts or the noise is very loud and the difficulties are not solved, it is necessary to fully consider the replacement of a new hydraulic motor mechanical equipment;

3. The air pollution of gear oil promotes the expansion of sliding friction force of exercise fitness parts. The solution is to check and clear Hydraulic transmission The system software filters the gear oil for several times or it is really difficult to replace the gear oil with zero environmental pollution and no residue;

4. It is found that the looseness and load caused by the internal exercise fitness parts. The solution is: calibrate the internal parts, restrain the loose parts or replace them with new ones;

5. In case of damage or cavitation of the four column hydraulic press of the system. The solution is to check and eliminate the gas in the water pump room.

Therefore, during daily operation, the working temperature of the hydraulic motor should generally be controlled below 70 ℃. If it is too high, Bulgarian cycloid motor Unable to operate, we should try to use refrigeration units. A wide range of refrigeration units have water cooling and air cooling. On the whole, the expected effect of water cooling is stronger. The higher the heating control of the hydraulic transmission system software, the higher the stability of the hydraulic transmission system software, and the hydraulic transmission system is not easy to have problems. Only then can we ensure the efficiency of daily production and processing.
