about Roots Blower Its good wear resistance plays a very important role in equipment operation. However, due to technical limitations, there are still some defects in the wear resistance of Roots blowers produced and sold by some manufacturers, and the wear resistance needs further improvement. Now Zhangqiu Fenggu Machinery Co., Ltd. will introduce what factors affect the abrasion resistance of the fan and effective improvement measures. Roots blower is often used in steel, power, cement, paper and other industries. The gas conveyed contains a large number of hard particles and corrosive substances, which have a strong corrosive effect on the blower when passing through it. Especially the impeller at the center of the fan, in the process of high-speed operation of the impeller, its wear is more serious than other parts. According to the experience of industry staff, the service life of impellers made of ordinary steel is usually relatively short, and even though they are processed with various wear prevention measures, the improvement of their service life is not very obvious. Among the commonly used wear prevention methods, the surfacing method is used more, which can achieve good wear prevention effect. However, a large amount of heat is required, and the inaccurate control degree will easily lead to the deformation of the impeller and can not be repaired. Thermal spray welding also has the same problem, thus limiting the use of such methods. At present, an effective way is to paste or inlay wear-resistant ceramics on the surface of the impeller volute. Such wear-resistant ceramics have good wear-resistant performance, which can effectively improve the wear-resistant performance of the equipment without causing deformation of the impeller.
