Problems and solutions to excessive noise in hydraulic pumps:

1. Noise caused by severe air suction:
   Possible reasons: The position of the oil suction port is too high, the oil level in the fuel tank is too low, the filter is clogged, the oil suction pipe is not tightly sealed, and the hydraulic pump rotates too fast.
   Solution: Adjust the height of the oil suction pipe or increase the oil level, clean or replace the filter, strengthen the seal of the oil suction pipe, and control the motor within a reasonable speed range.
2. Noise caused by poor operation of the hydraulic pump:
   Possible reasons: The internal parts of the hydraulic pump are damaged or worn.
   Solution: Disassemble the hydraulic pump and replace or clean the damaged parts.
3. Noise caused by structural problems of the hydraulic pump:
   Possible reasons: The variable mechanism is working abnormally and oil trapping is serious.
   Solution: Adjust or replace the variable mechanism and improve the hydraulic pump structure.
4. Noise caused by hydraulic pump installation problems:
   Possible reasons: irregular coupling installation, poor coaxiality between the motor and the hydraulic pump.
   Solution: Reinstall the coupling according to the standard and adjust the installation to meet the coaxiality requirements.
