The hydraulic oil of the hydraulic system of the injection molding machine may have the following failures during long-term use:
Hydraulic oil contamination: The hydraulic oil in the hydraulic system of an injection molding machine may be contaminated by dust, metal shavings, moisture, and other impurities. These contaminants may cause unstable operation of the hydraulic system and even cause system damage.
The hydraulic oil temperature is too high: When the hydraulic system of the custom mold manufacturing machine works for a long time, the hydraulic oil temperature may be too high. This will lead to the aging of the seals of the hydraulic system and the oxidation of the hydraulic oil, which will affect the working efficiency and life of the hydraulic system.
Unstable hydraulic oil pressure: When the pressure control elements in the hydraulic system fail, the pressure of the hydraulic oil may be unstable. This will affect the injection molding accuracy and production efficiency of the injection molding machine.
Hydraulic pump failure: The hydraulic pump is the core component of the hydraulic system of the injection molding machine. When the hydraulic pump fails, it will cause the hydraulic system of the injection molding machine to fail. Common hydraulic pump failures include oil leakage from the pump body, failure of the pump's suction line, etc.
In order to avoid these failures, the hydraulic system of the injection molding machine needs regular maintenance and replacement of hydraulic oil, and keeps the hydraulic system clean and sealed.
For the failure of the hydraulic oil of the injection molding machine, the following repairs and solutions can be taken:
Hydraulic oil foam: If there is foam in the hydraulic oil, you can check the sealing of the hydraulic system to ensure that there is no air in the hydraulic oil and that there is no air leakage in the hydraulic pump suction line. Additionally, anti-foaming agents can be used to combat foaming problems.
Hydraulic oil pollution: In order to solve the problem of hydraulic oil pollution, hydraulic oil and filters need to be replaced frequently to ensure the cleanliness and tightness of the hydraulic system.
Unstable hydraulic oil pressure: If the hydraulic oil pressure is unstable, it is necessary to check the pressure control components in the hydraulic system to ensure that they are working properly.
Hydraulic pump failure: When the hydraulic pump fails, the hydraulic pump can be replaced or the hydraulic pump can be repaired. When replacing or repairing the hydraulic pump, it is necessary to ensure that the installation is correct to ensure the normal operation of the hydraulic system.
