Noise analysis of horizontal injection molding machine

source:   time:2018-04-14   Click:2221

Abnormal noise produced by horizontal injection molding machine indicates that parts are damaged or not adjusted properly. We should identify the cause of noise and make immediate maintenance.

1, the hydraulic oil in the tank is insufficient, the oil pump inhalation air or the blockage of the oil filter will cause the oil pump to be short of oil, causing 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.

2, hydraulic oil viscosity is high, increase flow resistance, need to replace the right hydraulic oil.

3, due to the damage of the bearings or blades of the oil pump or motor, the concentricity deviation of the coupling causes noise, so we must adjust the concentricity or replace the parts.

4, the direction valve response failure, but the function is still in, such as the valve heart wear, leakage, burr blocking, movement is not flexible, the electromagnetic valve failure due to insufficient current will also produce noise. The way to solve the problem is to clean the spool, wear the valve core to replace the new parts, and the current must be stable and sufficient.

5, the damage of hydraulic components or the blockage of oil pipelines cause noise when hydraulic oil flows at high speed.

6, mechanical part failure, bearing wear or mechanical lack of lubricating oil or parts loosening, we should find out the reason to fasten or replace parts.
