How to operate cement mortar spraying machine? What are the precautions for cement mortar spraying machine operation? China Coal Group spraying machine manufacturers introduced the operation guide of cement mortar spraying machine and hoped to be helpful to everyone.
1. Before starting the cement mortar spraying machine, press the manual oil pump several times to inject oil to the transmission parts.
2. After the power is turned on, the main electric motor is firstly inspected to check if the rubber spiral rotates in the same direction. If it is inconsistent, it is necessary to change the phase of the power supply (this check must be performed every time the power is reconnected).
3. Connect the feeding hose and nozzle, add 5L of clear water to the hopper, start the motor to clear the water pump, and wet the hopper, pump body and conveying hose, and stop the water after most of the water is pumped out.
4. After the cement mortar is added to the hopper, the paint can be sprayed on (start the air compressor and open the air valve).
5. It is forbidden to idle in the hopper without material and without water.
6. After the work is completed, the hopper should be drained, and the hopper should be filled with enough fresh water to clean the hopper, and the pump should be turned on to clean the hose and nozzle until the pump is completely clear water, so as to avoid excess material in the hose. Solidify, clog hoses and spray heads.
7. If the downtime is too long, wipe the machine clean and remove the booster screw. After oiling, keep it properly and reinstall it when using it.
8. Insufficient pressure during work, adjustable booster stator bolts or replacement of pressurized rubber sleeves and booster worms.
9, before spraying, the area to be sprayed shall be penetrated by water; when spraying, the nozzle shall be as vertical as possible and the spraying surface (distance can be self-adjusted according to the spraying effect), stratified even spraying, and coordinated with the flattening process. If the wall is too dry or painted for too long, it will seriously affect the leveling effect and change the process.
10, to the hopper charge should be uniform, can not be interrupted, when the conveyor screw rotation, it is strictly prohibited with sticks in the hopper stirring to prevent injury.
11. Once the spray pipe is blocked, switch the switch to the manual position, open the compressor only, remove the quick connector at the front of the pump head, then block the spray head downwards, and the air pressure will produce reverse pressure and blow the slurry out of the pipe. Install the quick connector and start normal work.
12. When the sprayer operates, wear safety helmets, protective glasses, protective clothing and other protective equipment.
13. The pressurized rubber sleeve and the supercharging screw are wearing parts. In order to prolong the service life, the bolts of the supercharging stator are in a loose state when they are used for the first time. When the pressure is reduced and the flow rate is obviously reduced, the pressing bolts are adjusted to make them In normal working condition.
