Cleaning process and inspection work of biogas blower and Roots blower accessories
The biogas blower is a Roots blower for special gases. If it is damaged during use, it requires professional maintenance personnel to repair it. Generally, after disassembling the equipment, you need to clean the inside of the blower first, and then check the curvature and roundness of the shaft. , use colored penetrant and ultrasonic flaw detection to check whether there are cracks on the surface of the shaft. Check the surface of the impeller and the axial plane for cracks and blisters. Check the surface of the impeller and the axial plane for signs of friction. If there are scratches, this phenomenon is mostly caused by the blower being stored and transported for a period of time after leaving the factory. Deformation occurred due to improper aging treatment.
When the Roots blower or biogas blower accessories are cleaned in a immersion tank, the cleaning liquid in the tank is first heated to above 80 degrees, and then the metal parts to be cleaned are placed in the tank and soaked, supplemented by stirring. After soaking, there are two processes of hot water washing and cold water washing to remove residues on the surface of the fan parts, and then hot compressed air is used to dry the surface to prevent rust. Do not use alkaline solution for cleaning. You can wipe it with gauze and some alcohol.
Shandong Jinan Zhangqiu Blower Mingtian Machinery Group Co., Teo. stated that if the stainless steel wire on the filter screen is found to be deformed or damaged after cleaning the blower accessories, it needs to be replaced in time. When cleaning impurities, pay attention to protecting the mesh on the filter screen to avoid deformation or damage, otherwise the filter screen will not be able to perform as it should after being reinstalled. When cleaning the filter, if the surface of the filter is already very dirty, it needs to be washed with water to achieve a good effect.
