Unusual noise from the Horizontal Injection Molding Machine indicates that parts are damaged or improperly adjusted. The cause should be repaired according to the location of the noise.
1. The hydraulic oil in the fuel tank is insufficient. The suction of the oil pump or the dirt of the oil filter will cause the oil pump to be short of oil, causing the air bubbles in the oil to discharge and hit the blade to generate noise. The solution is to check the oil quantity and prevent the air from being inhaled. Clean the oil filter.
2, hydraulic oil viscosity is high, increase flow resistance, need to replace the appropriate hydraulic oil.
3. Due to the damage of the bearing or blade of the oil pump or motor, the concentricity deviation of the coupling causes noise, and the concentricity or replacement parts must be adjusted.
4, the directional valve reaction is not good but the function is still, such as valve core wear, internal leakage, burr blocking, movement is not flexible, solenoid valve failure due to insufficient current will also produce noise. The solution is to clean the valve core, the valve core must be replaced with new parts, and the current must be stable and sufficient.
5. The hydraulic component is damaged or the oil pipeline is blocked, causing noise when the hydraulic oil flows at high speed.
6. If the mechanical part is faulty, the bearing is worn or the machine lacks lubricating oil or the parts are loose, the reason should be found to fasten or replace the parts.
