Once the spray pipe of the cement mortar spraying machine is blocked, the switch is switched to the manual position, only the compressor is opened, the quick joint before the pump head is removed, and then the nozzle is blocked downward, and the wind pressure generates reverse pressure, which will be transported. The tube is blown out, and the quick joint is installed to start normal operation. When spraying hands, wear protective helmets, protective glasses, protective clothing and other protective equipment. The pressurized rubber sleeve and the booster screw are wearing parts. In order to prolong the service life, the booster stator bolt is looser when it is used for the first time. When the pressure is reduced and the flow rate is significantly reduced, the compression bolt is adjusted to make it normal. Working conditions.
