The first manual airbrush was invented by Thomas de Wilbiss at the beginning of the twentieth century. Since then, it has changed a lot, due to the following factors: productivity, spraying method, type of feed, method of forming an air torch, type of paint material.
Using
It is worth considering a manual airbrush with various pneumatic spraying systems for auto repair purposes. Despite the fact that the pistols of different systems are similar in appearance, they differ in the design of the air channels, as well as the structure of the head. This is understandable, because there is no point in changing the once developed body of the spray gun, excellent design and thoughtful ergonomics.
A manual airbrush can use one of several methods of supplying paints and varnishes. When forced by the pump, the pressure increases several times, after which the substance is fed to the sprayer. This method is suitable for those places where you want to paint a large area with one color for a long time. It is recommended to use a manual airbrush with a lower tank for painting large-sized parts, for example, the sides of cargo vans or the body with completely uniform monophonic enamels.
Modern auto repair and body repair stations build the work of the paint and body section so as to quickly master a large amount of minor daily repairs. The car moves from acceptance to delivery in accordance with the following scheme: reinforcing, tin, painting section, reinforcing again, so as not to lose time in the intermediate settling tanks. Such conditions make it possible to load the camera as much as possible with removable elements painted in different colors in one operation cycle.
Structural features
A manual airbrush has the following device and principle of operation. The design of the device is as simple as possible: a cylindrical body is used here, where a plunger pump is placed, which is activated by pressing the handle, and two hoses are connected to the body. One is used to absorb the substance from a bucket or other container, and the second is equipped at the end with a fixed gun for spraying the composition to the surface.
To actuate the manual spray gun KRDP, you must create pressure through a series of clicks on the handle. The valve opens when the handle is raised, while the composition enters the reservoir of the device from the external container, after which the suction hose should be pulled out of the container with paint, and then pump air into the device. When it is full, the composition can be sprayed, which opens the handle of the ball valve, which is located at the outlet. It also allows you to adjust the flow of paint and the intensity of its supply.
Everything is provided
Typically, a manual building spray gun is equipped with a long fishing rod, which allows standing on the ground to paint walls and other structures, the height of which is up to four meters. Wheels can be provided in the design of the device for the convenience of its movement on the construction site.
