Daily maintenance for extrusion blow molding machine
1.A plasticizing system
The gearbox needs regular oil change. 150 (or 220) medium extreme pressure industrial gear oil is selected. The new machine will use 500 hours for oil change, and then the oil will be changed every 3000 hours.When the machine just stops working and the gear box is still at a high temperature, change the oil. After the old oil is discharged, flush the sediment with a small amount of new oil, clean the filter of lubricating oil pump, and then fill the new oil to 1/2~2/3 of the liquid level window.
2. Maintenance of special hydraulic system for wall thickness control
Regular oil changes: 46 # anti-wear hydraulic oil hydraulic system is usually recommended to choose, xinji used after 500 hours, suggest the first oil change, and then once every 3000 hours in oil, oil change at the same time clean all filters (oil suction filter, high pressure filter, oil filter, servo valve seat filter) and tank, oil for liquid level gauge 1/2 ~ 2/3.
3. hydraulic system
Regular oil change: The hydraulic system is usually recommended to use 46# anti-wear hydraulic oil. After the 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, the oil change cycle may be different). When changing the oil, clean the filter and oil tank at the same time, and the oil amount is 1/2~2/3 of the level meter
4. Regular injection of extreme pressure lubrication oil
The mold shifting and opening and closing mechanisms operate frequently and move quickly, so automatic or manual lubrication devices are provided, but the lubricating grease in the lubricating device should also be checked and filled regularly.This can improve and prolong the service life of the machine, and bring better economic benefits for you.Oil the sliding rail separately once a week;The other parts of the shift once per shift the waterway
5.When the shutdown time is long and the temperature is low, the mold water channel, machine cooler, machine barrel cooling, mold head cooling water and other water channel cooling parts.To clean up the cooling water to prevent the long time structure or freeze crack.
