Maintenance of shot blasting machine parts under high temperature and humidity environment
In the high temperature and humidity environment, when the shot blasting machine is used, the reducer, motor, shot blasting machine blades, etc. are easy to generate heat, and the temperature of the air itself is high, which is not conducive to the heat dissipation of the shot blasting machine accessories. Under working conditions, the consumption of shot blasting machine accessories is greater than that in other seasons. . Since the shot blasting machine itself is in a rainy and humid environment, the electrical components of the shot blasting machine are prone to aging and short-circuit conditions, which require special attention. The steel grit of the shot blasting machine is easy to rust in a humid environment, and the rusty steel grit is easy to cause damage to the lifting belt of the shot blasting machine and the spiral of the shot blasting machine during use. More importantly, the oxidation and rust of the shot blasting machine parts have a great impact on the life of the shot blasting machine.
Therefore, the shot blasting machine should be overhauled at this time, and the parts of the shot blasting machine that need to be replaced should be replaced in time, and each oil injection point should be filled in time. When adjusting the material selection of shot blasting machine parts, materials with excellent quality should be selected, such as shot blasting machine guard plates, shot blasting blades, etc., which are made of high chromium. Shot blasting grease should be of high quality, and bearings should be made by regular manufacturers. The production workshop of the shot blasting machine should be well ventilated and cooled down.
Reasonably arrange the working hours of the shot blasting machine
Normally, the parts of the shot blasting machine are wear-resistant, and the wearing parts are all high-chromium wear-resistant cast iron. In terms of service life, the service life of the blade is less than 500H, and the side plate and top plate are less to reach 800H. The end plate should reach 1200H, and the directional set of blasting wheel can reach 1800H. Generally, the chamber body guard plate of the main machine is no problem within one year. Some shot blasting machines are still in good condition even after more than 2 years of use. However, some shot blasting machines found severe wear and tear on the parts of the shot blasting machine after two or three months of use. What is the reason?
During our use, we found that the continuous use of the shot blasting machine for a long time and non-intermittent use caused the steel plate to heat up. During the heating process, the steel shot was still constantly hitting the surface of the wear-resistant part, causing the surface to form a concave Point, using this way for a long time will cause the wear-resistant components of the surface of the wear-resistant parts to drop sharply, which will greatly reduce the service life of the wear-resistant parts. Therefore, during the use of the equipment, we must appropriately leave the shot blasting machine with a temperature drop. Time, so as to maintain the long-term good operation of the equipment.
