Hydraulic CNC bending machine running noise is too large

1, oil pump noise is too large (too fast heating), oil pump damage, blockage, oil dirty, oil pump suction and other problems. We also need to check if the pump speed is too high. We must choose the motor speed according to the higher rotary speed specified by the pump Hydraulic CNC bending machine .

2. Check whether the viscosity of the oil is too high. If so, be sure to replace the oil with the specified viscosity immediately Hydraulic CNC bending machine.

3, check whether the pressure has exceeded the rated pressure of the blade pump. If the pressure is higher than this, there will be a relatively loud phenomenon.

4, check whether there is compression and positioning of the stator, if the stator has the phenomenon of movement up and down, it will cause the output flow pulsation, and then bring noise, so we should tighten the adjusting screw.

5. There is an impact sound when fast falling. Is it the impact sound caused by the loosening of the guide plate
