If concrete dry shotcrete machines can adapt to such harsh environments and reduce maintenance, the daily maintenance of dry concrete dry shotcrete machines is essential. How to maintain concrete dry shotcrete machine ? Where do we need our attention?
1. Maintenance of rubber sheet of dry concrete shotcrete machine
The concrete shotcrete rubber sheet is not allowed to exceed the excessive stress caused by excessive clamping, otherwise it will be excessively worn due to friction and heat. The heat resistance limit of the rubber sheet is 1100C, and generally it is normal to use no more than 800C in use. Each class should be cleaned of rubber sheets and checked for wear. If the rubber sheets have been worn to such an extent that the steel ribs are flush with the surface of the rubber or the air holes and the feed holes are leaking, the rubber sheets must be replaced.
2, the maintenance of steel liner of dry concrete shotcrete
Concrete shotcrete steel liners must be inspected once a week and should be reground if deeper scratches are present. The edge of the round hole of the steel lining should be checked frequently. It must maintain sharp edges. If the edge is chamfered, the fine particles will easily penetrate into the joint surface and increase wear. If a new steel lining is replaced and the old steel lining hole has a beveled edge, the service life of the new steel lining will be significantly shortened. Timely repairing the steel lining to remove worn parts saves a lot of trouble and saves money.
3. Maintenance of the material cavity and elbow of concrete dry shotcrete machine
After each shift is completed, the material chamber of the concrete shotcrete and the discharge elbow should be cleaned in time.
4, the maintenance of concrete dry shotcrete reducer
1. The lubricating oil of the concrete shotcrete reducer is 50# industrial gear oil or 30# mechanical oil.
2. The temperature rise of the reducer should not exceed 40 degrees.
3. Clean the mixture attached to the surface of the reducer in time after each shift.
4, often observe the oil mark, when the oil is insufficient, fill it in time.
5. The lubricant should be replaced after 3 months of accumulated work.
6. Always check the gear unit for oil leakage and handle the leak in time.
7. Fill the bearings of the rotor square shaft with lubricating oil every week.
