The airless Spraying Machine means that the paint is pressurized by a pressure pump and then ejected through a special olive nozzle. The high-pressure paint flows out of the nozzle into the elbow, and immediately ruptures and breaks into a pole. The fine paint mist is sprayed directly onto the surface of the workpiece. It is also called the high pressure airless Spraying Machine. The use of airless Spraying Machine, the development of airless spraying technology and equipment, expands the application field of airless spraying, and has been widely used in ships, vehicles, steel structural parts, bridges, petroleum, petrochemical, construction and machinery industries. It is one of the most widely used coating methods, but I believe most people would like to know which of the Spraying Machine is the best? The most effective use. Below Changping Machinery Factory will take you to understand this high pressure airless Spraying Machine.

Airless spraying equipment generally consists of a power source, a high pressure pump, a pressure accumulating filter, a paint high pressure hose, a paint container, a spray gun, and the like.

Airless spray can be divided into hot spray type, cold spray type, electrostatic spray type, air subsidized type and the like. In the initial airless spraying, the gear pump was used to pressurize the paint, but the pressure was not high, and the atomization effect of the paint was not good at normal temperature. . In order to compensate for this defect, a method of preheating the paint and then pressurizing it is called a hot spray type airless spray. Due to the large size of the equipment, the use is limited and not widely used. Later, the plunger pump was used to pressurize the paint. The paint pressure was high, the atomization effect was good, the paint did not need to be heated, and the operation was relatively simple. This method was called cold spray type airless spraying. The spraying efficiency is high, the paint mist is less splashed, a thicker coating film can be obtained, and it is most suitable for large-area spraying of large workpieces, and thus it is generally adopted.
