The spray gun is manual: what should it be?

The first airbrush manual invented by Thomas de Vilbiss in the early twentieth century. Since then, it has changed a lot, which is due to the following factors: productivity, spraying method, type of feed, way of forming an air torch, kind of paintwork material.

Using

It is necessary to consider a manual spray gun with various pneumatic spraying systems for auto repair purposes. While the pistols of different systems are similar in appearance, they differ in the design of air channels, as well as in the structure of the head. This is understandable, because it makes no sense to change the once developed body of a paint spray gun, excellent design and thoughtful ergonomics.

A manual spray gun can use one of several ways of supplying paints and varnishes. When forced by the pump, the pressure is increased several times, after which the substance is fed to the nebulizer. This method is suitable for those places where it is required to paint large areas with one color for a long time. Manual spray gun with a lower tank is recommended for painting large parts, for example, sidewalls of freight vans or body entirely homogeneous monophonic enamels.

Modern car repair shops and dealerships repair the bodies of the body and body so that quickly learn a large amount of small daily repairs. The car moves from delivery to delivery in accordance with the following scheme: reinforcing, tin, painting site, again reinforcing, so as not to lose time in the intermediate clarifiers. Such conditions allow you to maximally load the camera with removable elements, painted in different colors for one cycle of work.

Features of the structure

The manual spray gun has the following device and operating principle. The design of the device is as simple as possible: it uses a cylindrical body 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 suck the substance from a bucket or other container, and the second is equipped at the end with a fixed gun to spray the composition onto the surface.

In order to activate the manual spray gun, it is necessary to create pressure by means of a series of strokes on the handle. The valve is opened when the handle is lifted, while the external container is fed into the reservoir of the device, after which the suction hose should be pulled out of the container with paint, and then pumped air inside the device. When it is filled, the composition can be sprayed, for which the handle of the ball valve, which is located at the outlet, is opened. It also allows you to adjust the paint consumption and the intensity of its supply.

Everything is provided

Usually a manual spray gun is equipped with a long stick-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 construction of the device for the convenience of its movement through the building site.
