Before we start to use a cement mortar spraying machine, we need to learn about how does the mortar spray machine work, which means what the working principle of the machine is. Only in this way can we use cement mortar spraying machine effectively.
The spraying machine is a special painting equipment that adopts the spraying technology. The principle is to control the airflow to instantly promote the reversing of the gas distribution reversing device, so that the piston of the pneumatic motor can perform a continuous and reciprocating motion.
The main working part of the mortar sprayer is a double-acting pneumatic and hydraulic booster pump, and the reversing mechanism is a special pilot-type of reversing device with full-air-operated valve. After entering the compressed air, when the piston moves to the upper or lower end of the cylinder, the upper pilot valve or the lower pilot valve will be actuated, and the air flow is controlled to promptly change the direction of the air distribution reversing device, so that the piston of the air motor can perform a more and more continuous and reciprocating motion. Because the piston is connected closely to the plunger in the paint plunger pump, and the area of the piston is larger than the area of the plunger which makes the suctioned paint pressurized.
Then the supercharged paint is delivered to the airless spray gun via a high-pressure hose, and finally the hydraulic pressure is released at the airless nozzle. After automation, the paint is sprayed onto the surface of the object to form a coating layer.
In general, working principle mortar spray machine is similar. Acquiring this knowledge, you can use stucco sprayer more easily and may know related skills, for instance, common obstacles you may meet during the use.
