How to handle the abnormal sound of cutting machine and change the hydraulic oil?

How to handle the abnormal sound of cutting machine and change the hydraulic oil?


What happens if the cutting machine suddenly has abnormal noise?

A. Insufficient hydraulic oil in the tank, oil sucked by the pump or blockage of the oil filter by the dirt will cause the oil pump to lack of oil, causing air bubbles in the oil to discharge and hit the blades to generate noise. The solution is to check the amount of oil and prevent air intake and cleaning. filter.

B. The hydraulic oil has a high viscosity and increases the flow resistance. It is necessary to replace the proper hydraulic oil.

C. Because the bearings or blades of the oil pump or motor are damaged, the concentricity of the coupling causes noise and the concentricity must be adjusted to replace the parts.

D. The directional valve fails to respond but the function is still there, such as valve core wear, internal leakage, burr clogging, inflexible movement, solenoid valve failure due to current failure will also produce noise. The solution is to clean the valve core or replace the new one. The current must be stable and sufficient.

E. Damage to the hydraulic components or blockage of the oil line, causing noise to occur when the hydraulic
fluid flows at high speed.

F. Mechanical failure, insufficient lubrication of parts, loose parts, should find out the reasons for fastening or replacement.

Hydraulic cutting machine how to change the hydraulic oil?

1 First put the original hydraulic oil clean.

2 Clean the oil tank and use a flushing oil or a degreasing agent.

3 Clean the oil filter or replace it to prevent damage to the valve pump.

4 Add new hydraulic oil.

5 Machine runs 200 hours or 15-20 days sampling comparison.

6 Strictly follow the hydraulic cutting machine manufacturer's instructions to maintain the machine.
