About 70% of the hydraulic system failures of injection molding machines at home and abroad are caused by pollution. The hydraulic oil in the hydraulic system is easily oxidized, and its oxide will bring certain harm to the hydraulic system, such as increasing the friction between the parts. Coefficient of friction, clogging of gaps in the joints of components, etc., these problems will eventually lead to the occurrence of hydraulic system failure.
When designing the hydraulic system of the injection molding machine, we must consider the hydraulic oil used in production, increase the bearing capacity of the materials used, and regularly test the hydraulic oil in the system after it is put into use. When the current oxidation degree is too high, it must be Carry out an oil change.
Experience has proved that the new hydraulic injection molding machine must be changed oil after one month of use, and the oil should be changed properly after being put into normal use, about once a year, so as to minimize the damage of the hydraulic oil to the injection molding machine. In addition, the cleaning of the oil filter is also very important. A comprehensive inspection of the cleanliness of the oil filter should be carried out every two months, and whether to replace the oil filter should be decided according to the results of the inspection.
