Aluminum profile extruder parts are damaged, what should I do

Aluminum profile extruder is a heavy equipment for extruding aluminum profiles. It extrudes aluminum and aluminum alloy bars, with large working load and high degree of wear. The following are some suggestions for equipment maintenance:

1. Before feeding, the purity of raw materials shall be checked, and foreign matters shall not enter the machine to avoid damaging the machine.

2. At ordinary times, check the lubrication degree of the transmission parts to avoid wear due to inadequate lubrication.

3. The aluminum profile extruder can only carry out seasoning extrusion operation when the forming die and barrel reach the specified heating temperature, so as to reduce the working intensity of the machine when extruding profiles.

4. The rotating speed of the screw shall be gradually increased from low to high, and the idling time in the cylinder shall be less than 2-3 minutes.

5. When the screw runs empty in the barrel, pay more attention to the working state of the main motor of the extruder.

6. Pay attention to the working state of extruder motor at any time and avoid overload for a long time, which will shorten its service life.

7. The connection of all parts shall be checked, and the fixing bolts shall be operated according to the specifications to check whether they are loose.

8. Each lubrication part shall be checked every shift to see whether it is fully lubricated.

9. The bearing temperature of aluminum profile extruder shall not exceed 50 ℃.

10. The residues on the screw shall be cleaned in time.

11. After daily work, the residues left after extrusion by the aluminum profile extruder shall be cleaned in time, including the cleaning of molds, screws and barrel.

12. Clean the filter screen of the oil pump regularly to protect the oil pump dial and pump body. Properly check the temperature difference between the oil pump and the new oil pump with a thermometer, so as to know the relative leakage of the oil pump. No matter how well the sealing condition of the oil suction pipe is, the oil pump has a certain suction condition, so you should pay special attention to the oil in the oil tank.

13. Maintenance is to accumulate experience. Usually, use hands to sense the temperature of the valve body on the machine.

14. In case of problems, timely record the maintenance, prevent the same fault next time, and have a certain perception of the speed of the machine, so as to avoid the possibility of overhaul.

15. Be sure to keep the hydraulic oil clean. If there is a hole on the surface of the mailbox, it can't be repaired. Specially, the hole on the surface of the oil return pipe penetrating into the oil tank must be sealed with rubber.

16. The machine pressure and atmospheric pressure shall be frequently detected, and the three currents of the motor shall be measured at the side of the ammeter to protect the normal operation of the motor from sudden shutdown caused by burning the motor or motor overload.
