　　PZ-7Dry concrete spraying machineOperation Manual

　　1. Before starting each shift, press the manual oil pump several times to inject oil into the transmission parts. 2. After connecting the power supply, first drive the main motor and check if the rotation direction of the rubber screw is consistent. If not, replace the power phase line (this check should be performed every time the power supply is reconnected)

　　3PZ-7 dry concrete spraying machineConnect the conveying hose and nozzle, add 5L of clean water to the hopper, start the motor to pump out the clean water to wet the hopper, pump body, and conveying hose. After most of the water is pumped out, stop the machine.

　　4. Add putty or paint to the hopper to start spraying (the air should be started first)

　　5. It is strictly prohibited to idle the hopper without any material or water.

　　6PZ-7 dry concrete spraying machineAfter the work is completed, the remaining material in the hopper should be drained, and enough clean water should be injected into the hopper to clean it. The hopper should be started and the pump should be turned on to clean the hose and nozzle until all the pumped material is clean water, in order to prevent the remaining material from solidifying in the hose and blocking the hose and nozzle.

　　7. If the downtime is too long, wipe the machine clean, remove the booster screw, apply oil, store it properly, and reinstall it when in use.

　　8PZ-7 dry concrete spraying machineIf the pump output pressure is insufficient during work, the booster stator bolts can be adjusted or the booster rubber sleeve and booster worm can be replaced.

　　9. Before spraying, the sprayed area should be permeated with water; When spraying, the nozzle should be perpendicular to the sprayed surface as much as possible (the distance can be adjusted according to the spraying effect) and sprayed evenly in layers, and coordinated with the leveling process. If the wall is too dry or sprayed for too long, it will seriously affect the leveling effect, and the process needs to be changed.

　　10. The material should be evenly loaded into the hopper without interruption. When the conveying screw rotates, it is strictly prohibited to use sticks to stir inside the hopper to prevent injury.

　　11. Once the spraying conveying pipe is blocked, switch the switch to manual position, only turn on the compressor, remove the quick connector in front of the pump head, and then block the nozzle downwards. The air pressure generates reverse pressure to blow out the remaining slurry in the conveying pipe. After installing the quick connector

　　12PZ-7 dry concrete spraying machineWhen operating a spray shooter, they should wear safety helmets, protective goggles, protective clothing, and other protective equipment.

　　13. The booster rubber sleeve and booster screw are vulnerable parts. In order to extend their service life, the booster stator bolts are in a loose state during initial use. When the pressure decreases and the flow rate significantly decreases, the tightening bolts should be adjusted to ensure that they are in normal working condition.
