First, before the start of the preparation and the test machine
1. Check the air pressure and water pressure reaches a predetermined value
2. Check the hose pipe and each node is solid.
3, to be safe, check the direction of the spray gun head, alignment and other equipment are not allowed.
4. Check gas, water, feed conduit is smooth, with or without breakage of place.
5, total machine open air valve, check the total pressure, a pressure tank pressure reading is correct.
6, open the valve and check whether there is enough water in the outflow from the gun, turn off the main water valve.
7, turn off the machine total air valve, open the tank pressure release valve and check valve must be switched off next.
Second, start gunning
1. Before opening the total air valve, you must check off on the direction of the spray gun head is in the correct position.
2, gunning workers head into the mouth of the gun, and open the valve, sending a small amount of water through the pipes.
3. Open the feed switch, observe gunning adjust the amount of water from the tube when the material began to appear and start gunning target zone of the furnace.
Third, gunning complete
1. gunning after completing the first turn off the feed handle stop gunning outflow.
2, gunning workers removed from the mouth of the barrel.
3. When all the material within the vent hose, will be closed to observe a valve.
4, gunning to stop the flow after 20 seconds, shut the total valve.
5, the tank pressure release valve to open, to eliminate the pressure tank, in order to ensure that the next charge safety.
6, finishing barrel, hoses and other items.
7, good gunning record.
