Shotcrete Machine Should Be Stop Feeding Before Shut-Down

Shotcrete machine standard operating: Firstly: A preparation of operation 1. Check shotcrete machine is in good condition, and the transmission power of no-load operation, tighten the friction plate, do not appear leakage phenomenon. 2. Open for air, water supply valve, check the air pressure, water pressure, and check on the  pipeline whether leakage, water leakage, smooth, if the problem dealt with in a timely manner. 3. Check whether the damaged pipe is damaged, the replacement of the feeding tube. 4. Wash the rock with high pressure water spray before use. Second: The sequence of operations 1. The boot standard order of operations: water supply, open air pressure to open, adjust the air pressure, hydraulic pressure spraying machine, feeding and spraying. 2. Normal stop operation sequence: stop feeding, stop spraying machine to shut off the water to stop the wind 3. Stop immediately, and then turn off the water, stopped the wind finally when shotcrete machine is blockage fault. Third: Feeding 1.Feeding staff to follow the injection machine driver’s leadership, injection machine normal operation, Brigadier General mix mixture to injection machine hopper. 2.The normal injection process, material to the continuous and uniform storage hopper should always be enough. Can not be forced to raise the feeding rate, feed control excessive spraying machine load is too large. 3.Accelerating agent to uniformly and proportionally added, should be with the milling material, with a small amount of plant organic accelerating agent. 4.Should be stop feeding before shut-down machine. Four, finish the sequence of operations: 1. After finish the shotcrete machine works, close the water valve, remove the nozzle, clean water and spraying machine. 2.The conveying pipe and pipe should be in right place. 3. Check the injection quality, and label the unqualified place next fill spraying.
