The shot blasting machine is a kind of mechanical equipment. If it is more complicated, it is a kind of casting equipment that can strengthen the appearance of castings.

In the application of the shot blasting machine, the shot blasting machine manufacturer is initially used to remove the sand and oxide skin on the surface of the workpiece, and the shot blasting speed is 50-100nds. But later, it was gradually given some other new functions, and then it was more widely used.

In terms of rust removal grade, it is generally divided into four grades, which are expressed by Sa, and the detailed meaning is:

Sa1: light grade, only invisible grease and dirt on the surface of the workpiece are needed, and there are no attachments with poor adhesion, including oxide skin, rust and paint coating.

Sa2: cleanliness level. As for Sa1 level, if there are attachments, they should be solid. Moreover, the anti sliding coefficient reaches 0.35-0.45.

Sa3: It is required to be very clean. Even if there is residue, it can only be a slight spot or strip stain. Its anti sliding coefficient should reach 0.45-0.5.

Sa4: It is of high grade, and it is required to be completely free of residues, attachments, etc. And the surface of the workpiece should show a metallic luster.

As for these important and fundamental things, we should treat them well so that we can apply what we have learned.

1. Cause analysis and treatment of oil leakage of shot blasting machine

The shot blasting machine manufacturer believes that there are three reasons for this problem and has corresponding treatment methods.

Cause 1: The friction between the shaft and the hole is too large, which makes it severely worn, thus causing oil leakage. If you want to deal with it, you can seal the rubber ring to prevent excessive wear.

Cause 2: The shot blasting machine switch leaks oil, which may be caused by valve wear or rust. At this time, it should be replaced in time, and some preventive measures should be taken to prevent corrosion.

Cause 3: The seal is damaged or the fastener is loose. For these two problems, it is very simple to replace the seals and tighten the fasteners.

2. Safety instructions for operation of shot blasting machine

In terms of equipment, the shot blasting machine manufacturers mainly include:

(1) Operators must wear labor protection articles before they can work, otherwise they are forbidden to work.

(2) The dedusting equipment shall be opened periodically to remove clean dust, etc. In addition, when the equipment is shut down, the operation of the dedusting equipment cannot be stopped immediately.

(3) The control switch in the shot blasting machine cannot be opened and closed frequently, because it will cause excessive current and damage some instruments in the equipment.
