The application of wet mix shotcrete machine in tunnel construction is becoming more and more common. More and more customers will always encounter many problems in the process of using wet mix shotcrete machine. Have some questions about the maintenance of wet mix shotcrete machine? How much do you know about the maintenance of wet shotcrete machine?
1. When does the oil in the wet mix shotcrete machine need to be replaced?
Check the hydraulic oil level and quality of the wet shotcrete machine. The oil quality should be light yellow and transparent, without emulsification or contamination, or it should be replaced immediately. When the air leakage on the side of the rotor body is severe, check whether the gap between the limit seat and the hopper seat is appropriate.
2. The running speed of the wet mix shotcrete machine is sudden and slow?
You should first check whether the voltage of the wet mix shotcrete machine is stable. If the voltage is normal, then you need to check the working conditions of the smooth system. You should see the progressive distributor indicator rod moving back and forth, the bearing position of the S-tube swing arm end, the bearing position of the mixing shaft and other smooth points There is slippery oil overflow; then turn it on again to investigate whether the distribution valve is reversing and the mixing equipment is rotating normally. When the pressure of the wet shotcrete machine is low and the eruption effect is not ideal, you can check whether there is oil leakage or oil leakage in the hydraulic system. Always check all threaded connections of the wet mix shotcrete machine to ensure that the connections are strong.
