Automatic mortar spray machine is a special coating equipment that uses spraying technology. The principle is to control the air flow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor makes a stable and continuous reciprocating motion.
The main working part of the automatic mortar spray machine is a double-acting pneumatic hydraulic booster pump, and the reversing mechanism is a special form of pilot fully air-controlled air distribution reversing device. 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 is actuated, and the air flow is controlled to instantly push the air distribution reversing device to reverse, so that the piston of the air motor makes stable and continuous reciprocating motion. Because the piston is rigidly connected with the plunger in the paint plunger pump, and the area of the piston is larger than that of the plunger. This pressurizes the paint.
The pressurized paint in the automatic mortar spray machine is transported to the airless spray through the high-pressure hose, and then the hydraulic pressure is released at the airless nozzle, and sprayed on the surface of the object after instantaneous atomization to form a coating layer.
