When the pump rotor at high speed, if the quality is not balanced, it will produce a large centrifugal force rotation, vibration or damage caused by the pump. The balance of the rotor is balanced by the quality of its individual member (including the shaft, impeller, bushings, balance disk, etc.) to achieve, so the new facelift of the impeller static balance calibration work should be carried out. The impeller mounted on the shaft false, it has leveled into the static balance test bench. Test bench with two tracks in a pump rotor shaft can scroll leave on freedom. Pumps in the long run the process, often occur pump bracket bearing chamber wear, bearing bit wear, cracks broken pump, pump cavitation, erosion and wear. The above problems, the traditional solutions business is machined after welding or brush fix, but there are some drawbacks of both: the thermal stress generated by welding high temperature can not be completed eliminated, could easily lead to material damage, leading members appear bent or broken ; and electric brush by coating thickness restrictions, easy to peel off, and the above two methods are used to repair metal stainless metal pump, can not change the "hard on hard" cooperation relations in force under the combined effects of each, still cause wear again. Stainless steel pump, water pump Xin Cheng (certification), the pump is provided by Hebei Xin-pump factory. Hebei Xin-Pump Plant (www.shuibeng999.com) (www.shuibeng999.com) Hebei Baoding, centrifugal pumps leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. Xin-pump in leadership with the staff warmly welcome all inquiries negotiations to create Xin Cheng pump better future.
