Steel pipe rust remover is a combined rust remover for cleaning the inner and outer walls of steel pipes. The outer surface of the steel pipe is cleaned by shot blasting, and the inner surface is cleaned by shot blasting to remove the surface oxide scale.

The machine mainly uses the high-speed shot blasting flow thrown by the high-efficiency and powerful shot blasting machine to impact the surface and inner cavity of the rotating workpiece located in the chamber, and remove other impurities such as sand, rust layer, welding slag, oxide scale, etc., so as to obtain a fine and smooth surface. The adhesion between paint film and steel surface is improved, the fatigue strength and corrosion resistance of steel are improved, the internal quality of steel is improved, and the service life is prolonged.

Structural principle:

The double discs in the shot blasting machine are riveted into a whole to form the impeller body. Eight blades are installed on the impeller body, and the impeller body is installed on the main shaft driven by the motor together with the shot-dividing wheel located in the center of the shot-blasting wheel. The cover is lined with a guard plate, and the cover shell is provided with a directional sleeve and a medicine inlet pipe.

When working, the shot flows into the shot blaster from the shot inlet pipe. The shot dividing wheel rotating synchronously with the blade enables the shot to obtain the initial velocity. The projectile flew out of the window of the directional sleeve and was thrown on the high-speed rotating blade outside the directional sleeve. After being further accelerated by the blade, it is thrown to the surface of the cleaned workpiece. Because the synchronous rotation of the indexing wheel and the blade ensures that the projectile is transmitted to the blade without vibration, the wear on the blade is reduced.

The principle of shot blasting is to use the motor to drive the impeller to rotate (directly or through V-belt transmission), and shot blasting (including cast steel shot, steel wire cut shot, stainless steel shot, etc.). ) the diameter is about 0.2 ~ 3.0, and it moves to the surface of the workpiece under the action of centrifugal force, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, or changing the welding tensile stress of the workpiece into compressive stress, and improving the service life of the workpiece.

By improving the surface smoothness of the workpiece, the adhesion of the paint film for subsequent coating of the workpiece is also improved. Shot blasting is applied to almost all fields of machinery, such as shipbuilding, automobile parts, aircraft parts, artillery and tank surfaces, bridges, steel structures, glass, steel plate profiles, corrosion protection of internal and external walls of pipelines and even pavement.
