The working principle and structure of the sprayer end? The main working part of the spraying 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 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 a stable and continuous reciprocating motion .
Spraying machine
Because the piston is rigidly connected to the plunger in the paint plunger pump, and the area of the piston is larger than the area of the plunger. This pressurizes the sucked paint. The pressurized paint is conveyed to the airless spray gun through the high-pressure hose, and the hydraulic pressure is released at the airless nozzle, and sprayed on the surface of the object to be coated after instantaneous atomization to form a coating layer.
The spraying machine is mainly composed of a feeding device, a spray gun, and an atomization source. The source of atomization varies with different types and sprayers: the source of atomization of air sprayer is composed of air compressor, air pipe, air oil-water separator, and air storage tank; the source of atomization of airless sprayer is power source , High-pressure pump composition; the atomization source of electrostatic spraying machine is composed of high-frequency and high-voltage electrostatic generator.
It is composed of two parts: shotcrete and drying. The working mechanism includes a spray booth equipped with nozzles, a leather-carrying conveyor belt, a drying system, and a cleaning mechanism. After 2012, the rotary multi-nozzle airtight spraying chamber is mostly used, and the nozzles are opened and closed by ultrasonic or computer control, which realizes that there is leather spraying, and no leather is sprayed; it saves coating agents, reduces pollution, and has high coating efficiency. The sprayed leather is sent to the drying zone by a conveyor belt, and collected from the other end after drying.
The spraying machine is a special spraying equipment using high-pressure airless spraying technology.
High-pressure airless spraying, also known as airless spraying, uses a high-pressure plunger pump to directly pressurize the paint to form high-pressure paint, and spray out the muzzle to form an atomized airflow that acts on the surface of the object (wall or wood) surface). Compared with air spraying, the paint surface is uniform and non-grainy. Due to the isolation from the air, the paint is dry and clean.
Airless spraying can be used for the construction of high-viscosity paint, and the edges are clear, and it can even be used for some spraying projects with boundary requirements. Depending on the type of machinery, it is also divided into pneumatic airless sprayers, electric airless sprayers, and internal combustion airless spray sprayers.
