Generally speaking, the vulnerable parts and wear-resistant parts of the shot blasting machine are made of high-chromium wear-resistant cast iron. In terms of service life, the service life of the blade is more than 500 hours, the service life of the side plate and top plate is at least 800 hours, the service life of the end plate is 1200 hours, and the service life of the directional sleeve pill wheel is 1800 hours. There is no problem with the protective plate in one year. Some shot blasting machine equipment is still in good condition even after more than 2 years of use, and some shot blasting machine parts are severely worn after 3 or 4 months of use. In addition, in a high-temperature and high-humidity environment, the motor, blades, and reducers of the shot blasting machine are prone to heat when used. The air itself is high in temperature, and it is difficult for the accessories of the shot blasting machine to dissipate heat. When operating under such conditions for a long time, the consumption of the accessories will be Increase exponentially. Because the shot blasting machine itself is in a humid, rainy and sultry environment, the electrical components of the shot blasting machine will be seriously aging and easy to short-circuit, which requires special attention. The steel grit used in the shot blasting machine is easy to rust in a humid environment, and the rusty steel grit is easy to damage the spiral and lifting belt of the shot blasting machine during use.　　 Therefore, the shot blasting machine should be overhauled in a high temperature and high humidity environment. Parts that need to be replaced should be replaced in time, and all refueling points should be refueled in time. In addition, when choosing materials for shot blasting machine accessories, high-quality materials should be selected, such as shot blasting machine protection plates, blades, etc. It should be made of high chromium, and the grease should be made of high-quality bearings that meet national standards. At the same time, the production workshop should be ventilated to lower the temperature. As long as you achieve the key points described above, you can more effectively extend the service life of the shot blasting machine, and will not bring unnecessary losses to the enterprise.
