The working principle of the spraying machine feeds the stirred material from the discharge port of the batching mixer through the vibrating screen to the hopper of the spraying machine, and the dialing device is used to inject the direct feed cavity of the rotor body into the cavity. At the mouth of the material, compressed air is introduced from the air chamber and the material is blown into the discharge elbow. Here, another cyclone is used to introduce the other air pressure. It rotates, floats, enters the feeding tube, reaches the nozzle and adds a small amount of additional moisture or liquid accelerator.
Before starting the spraying machine, check whether the connecting parts of the spraying machine are firm, and whether the rotating sliding parts are flexible and reliable.
2. Observe the cursor and check if the lubricant in the gearbox is sufficient.
3, the drive motor and power connection, jog motor, observe the rotation direction of the font should be consistent with the direction of the arrow, otherwise the power phase modulation.
4. The main gas line, upper gas line, lower gas line, vibrator gas line, and sprinkler water supply stop valve are placed in the closed state, and the main gas line is connected to the gas source. The water supply pipe is connected to the water source, and the feed pipe is connected to the host.
5, adjust the compression mechanism, the first manual preloading, and then use the wrench tighten, bend the feed pipe, open the main gas, the gas valve, observe the pressure gauge in the city around 0.3Mpa, the rubber plate should not Gas spills.
The flow of the spraying machine first opens the main gas line, the upper gas line, the lower gas line stop valve, opens the sprinkler water supply cut-off valve, pre-wet the surface of the rock mass, then starts the motor, opens the vibrator gas path stop valve, and adds the mixing in the hopper Material, start spraying operations. The nozzle operator should adjust the nozzle water supply appropriately to ensure that the concrete material has a suitable water-cement ratio. The spraying machine operator should pay attention to observing the remaining air hole on the side of the main machine. If there is excess material discharged, the air supply volume of the lower gas path should be appropriately reduced. Until there is no material discharge at the remaining air outlet of the machine, the equipment will work normally. Before stopping the spraying machine, stop feeding first. When no material is ejected from the nozzle, close the water supply cut-off valve. At the same time, add a small amount of wet gravel to the hopper. Scrub the residue in the hopper and rotor cavity several times. When no material is ejected from the nozzle, turn off the motor power supply and each air shutoff valve.
