OURS4533 Airless paint sprayer painting equipment

High-pressure airless spraying, also known as airless spraying, refers to the use of high-pressure plunger pumps, directly pressurized paint, forming a high pressure paint, sprayed out of the muzzle of the gun to form an atomized airflow acting on the surface of the object (walls or wood surfaces) of a kind of spraying method.

Compared to airborne spraying, the paint surface is uniform and free of particles. The paint is dry and clean because it is isolated from the air. Airless spraying can be used for high viscosity paints with clear edges, even for some spraying projects with boundary requirements. According to the type of machinery, it is also divided into pneumatic airless sprayers, electric airless sprayers, internal combustion airless sprayers and many other types.

Structure principle

Pneumatic Hydraulic Principle Diagramlum

Figure1 Pneumatic Hydraulic Principle Diagram

The working part of equipment is double-acting pneumatic hydraulic pump. Reversing mechanism is special guide type pneumatic two-position and four-way slide valve. After the compressed air is entered, when the piston moves to top or bottom of cylinder, it will push up the two-position and two-way valve installed at the up and down ends of cylinder (pilot valve), control the immediate rushout of the airflow, drive the reversal of special guide type pneumatic two-position and four-way valve, so that make the piston in the cylinder do reciprocating motion. The force caused by the up and down motion of cylinder piston acts on the plunger in the paint cylinder, the area of the cylinder piston is larger than coating cylinder’s, so the paint is pressurized.

Installation

For the convenience of transportation, handle has been disassembled from the frame, and the high pressure hose, manual airless spray gun are not connected well, so after unpacking the box, the first thing is to install. We will send you an manual to guide you after your purchase.
