What does the machine have to do with a different noise? [Ponse cutting machine]
The hydraulic oil in the A. tank is insufficient, the oil pump inhaled air or the oil filter is blocked by the dirt, which will cause the oil pump to lack oil, which causes the bubbles in the oil to discharge the impact blade to produce noise. The solution is to check the amount of oil, prevent the air from inhaling and clean the filter.
B. hydraulic oil viscosity is high, increase flow resistance, need to replace the appropriate hydraulic oil.
C. because the bearing or blade of the oil pump or motor is damaged, the concentricity deviation of the coupling causes noise, and the concentricity must be adjusted to replace parts.
D. valve response failure, but the function is still in, such as valve heart wear, leakage, burr blocking, movement is not flexible, the electromagnetic valve failure due to the current can also produce noise. The solution is to clean the valve core or replace the new parts. The current must be stable and sufficient.
E. hydraulic components damage or oil pipeline blockage, making hydraulic oil noise when high-speed flow.
F. mechanical part failure, machine parts lubrication is insufficient, parts loose, we should find out the reason to fasten or replace it.
