Description

Paint spraying device with airless pump {APPARATUS FOR SPRAYING PAINT USING AIRLESS PUMP}

The present invention relates to a paint injector, and more particularly to a paint injector having an airless pump for painting the paint to prevent corrosion of structures such as bridges and ships.

In general, steel structures such as bridges and ships shorten their lifespan due to corrosion. To prevent this, various anti-corrosive paints are applied to prevent the corrosion of moisture, oxygen, salts, etc. It suppresses oxidation.

As such, a painting apparatus using an airless pump is used as a painting apparatus used to coat the paint. A paint injector having an airless pump directly pumps paint by pressurizing the paint by actuating the delivery pump rod by high pressure air, i.e., a pump configured to spray paint by means of inorganic spraying, without using high pressure air directly to inject paint. Use a pump to inject.

In addition, the paint injector having a conventional airless pump is usually implemented in a weight-measuring mixing form or volumetric two-component pump form. In this case, the weighing type mixing form simply mixes the paint, and uses a mixing tank having a weighing function. In addition, the volumetric mixing mode is a method of measuring the discharge amount of the paint by measuring the stroke length of the piston by installing an encoder for measuring length and the like in each of the two airless pumps.

However, the conventional paint spraying device having an airless pump should have a separate temporary storage tank for injecting two liquids of the main agent and the curing agent into each other, and in this temporary storage tank, the liquid is simply mixed and sprayed with a separate pump. Due to the complicated configuration, it is difficult to spray the paint at the correct mixing ratio.
