1、 Plasticizing system
Gearbox oil needs to be changed regularly. 150 (or 220) medium and extreme pressure industrial gear oil should be selected. The new machine should be used for 500 hours and then changed every 3000 hours. When the machine just stops working and the gearbox is still at a high temperature, change the oil. After the old oil is discharged, clean the sediment with a small amount of new oil, clean the filter of lubricating oil pump, and then add new oil to 1 / 2 ~ 2 / 3 of the liquid level window. 2、 Maintenance of special hydraulic system for wall thickness control
Regular oil change: 46 # anti-wear hydraulic oil is generally recommended for hydraulic system. After 500 hours of service, it is recommended to change the oil for the first time, and then change the oil every 3000 hours. At the same time, clean all filters (oil suction filter, high pressure filter, oil return filter, servo valve seat filter) and oil tank, and the oil volume is 1 / 2 ~ 2 / 3 of the liquid level gauge.
3、 Hydraulic system
Regular oil change: 46 ා anti-wear hydraulic oil is generally recommended for hydraulic system. After a new machine is used for 500 hours, it is recommended to change the oil for the first time, and then change the oil once a year (the oil quality is different, and the oil change period may be different). When changing the oil, clean the filter and oil tank, and the oil volume is 1 / 2 ~ 2 / 3 of the liquid level gauge
4、 Add extreme pressure grease regularly
The mechanism of moving mold and opening and closing mold has frequent action and fast movement speed, so it is equipped with automatic or manual lubrication device, but the lubricating grease in the lubricating device should be checked and filled regularly. This can improve and extend the service life of the machine and bring you better economic benefits. The sliding block of moving mould guide rail shall be oiled separately once a week; other parts shall be filled once a shift. 5、 Waterway
When the shutdown time is long and the air temperature is low, it is necessary to cool the mold waterway, machine cooler, barrel, and mold head cooling water. The cooling water should be cleaned up to prevent the structure from cracking for a long time.
