What are the reasons for the failure of the sand molding machine?(2)
2. When operating the sand molding machine, due to long-term vibration, the following molding machine failure will occur: 6 M20 hexagonal nails connected to the shaking table and the shock piston are loose, so that there is a gap between the shaking table and the piston, and the working airflow Leaking from here, causing shocks, especially after compaction, can not be shocked.
3, the lubrication is not sufficient, if the piston and the pump iron are not lubricated, rust will occur, it can also cause shock and weakness. To solve the problem of the molding machine, you can open the rubber tube to the shaking table, inject a kilogram of kerosene or gasoline, and start the shock. At this time, the sound of the shock will change significantly.
