What should I do if the oil temperature of the horizontal injection molding machine is too high?

Jul 31, 2020

When you use a small injection molding machine, there may be problems of one kind or another. I believe many people have encountered the problem of excessive oil temperature. So what should I do if the oil temperature of the horizontal injection molding machine is too high? Different situations require us to adopt different methods to deal with.

 

    If the oil temperature of the horizontal injection molding machine is abnormal, it may be caused by the high heat generated by the hydraulic component itself, or the failure of the internal cooling system of the machine. If it is caused by an abnormality in its own cooling system, it is likely to be due to its own insufficient supply, such as insufficient water pressure, for example, the flow rate of the water pump does not meet the demand. If the temperature of the cooling water is too high, it may be caused by the abnormal heat dissipation function of the cooling tower, or it may be caused by the high temperature.

 

    When using a horizontal injection molding machine, the hydraulic system has high temperature, so there are three situations. One: Because the oil pump is damaged, the internal parts suffer from abrasion and high heat when rotating at high speed in the working state; Two: The pressure is adjusted incorrectly, if the hydraulic system is in a high pressure state for a long time, then The overheating problem naturally arises; three: the hydraulic components have internal leakage, which is the last possibility. So what conditions can cause this situation? For example, if the sealing ring is damaged or the directional valve is damaged, heat will be generated when the high pressure is circulated. If the heat accumulates too much, naturally there will be a problem of excessive oil temperature.

 

    The above points are the specific reasons for the high oil temperature. After everyone understands the fault, I believe that after the failure, they can be more confident in the maintenance of the small injection molding machine.
