How to operate the dry sprayer correctly? Henan Yuli sprayer manufacturers introduced in detail the operating rules of dry sprayer and hoped to help dry gun sprayers.
1. Preparation of the Dry Sprayer before starting up A. Check whether the connection parts of the sprayer are firm and whether the rotating and sliding parts are flexible and reliable.
B. Observe the cursor and check if the lubricating oil in the gearbox is sufficient.
C. The drive motor is connected to the power supply. The direction of rotation of the rotary motor should be the same as the direction of the arrow. Otherwise, the power supply should be phased.
D. The main air line, upper air line, lower air line, vibrator gas line and sprinkler water supply cut-off valve are closed, and the main air pipe is connected to the air source. The water supply pipe is connected to the water source, and the feed pipe is connected to the host.
E. Adjust the compression mechanism, manually pre-pressing, then use a wrench to tighten, bend the feeding pipe, open the main gas line, upper gas valve, observe the pressure gauge in the city around 0.3Mpa, rubber joint plate should be No gas spills.
2. Spraying process of dry spraying machine First, open the main gas line, upper gas line, lower gas line stop valve, open the sprinkler water supply cut-off valve, pre-wet the surface of the rock mass, and then start the motor, open the vibrator gas line stop valve Mixing material is added to the hopper to start the spraying operation. The nozzle operator should adjust the nozzle water supply appropriately to ensure that the material has a suitable water-cement ratio. The host operating personnel should pay attention to observing the remaining air hole on the side of the main machine. If any residual material is discharged, the air supply volume of the lower air line should be appropriately reduced. Until there is no material discharge at the remaining air outlet of the machine, the equipment will work normally.
3. Before the shutdown of the dry type spraying machine stops, the feeding is stopped first. When no material is ejected from the nozzle, the water supply cut-off valve is closed. At the same time, a small amount of wet gravel is added to the hopper, several times will be in the hopper and rotor material cavity. When the material is flushed and no material is ejected from the nozzle, turn off the motor power supply and the air shutoff valves.
