Inspection of biogas fans and other special gas fans before use
The biogas blower is a special gas blower. If it is not used for a long time and is used again, you must first check whether the various parts of the blower are still firm. Once you find any looseness, you must tighten it in time so that the blower can be used again. During the trial operation, the blower will not be unable to function normally due to looseness of the blower components. Before starting the blower, it is necessary to check whether there are any objects in the centrifugal blower and the pipe that hinder the rotation. If any, they should be removed before starting.
When using the biogas blower, you should also pay attention to the fact that the thermal stress caused by the high temperature of the repair welding cannot be completely eliminated, which can easily cause material damage and cause the components to bend or break. The brush plating is limited by the thickness of the coating and is easy to peel off. The most widely used ones have super strong adhesion, excellent compressive strength and other comprehensive properties, and can be disassembled or machined without any need. There is no influence of thermal stress of repair welding, and the repair thickness is not limited. To avoid the possibility of re-wear, a more reliable method should be adopted.
The editor of Zhangqiu Blower Mingtian Machinery in Jinan, Shandong Province said that if the blower is not used for a long time, the flexibility of the safety valve should be checked daily. If it is not flexible, please clean and adjust it to ensure reliable opening and closing. Check for oil and air leaks and repair them. If repairs cannot be made, please notify the manufacturer immediately. Clean the blower room daily to keep it clean and well ventilated. Frequently check the operating status of the blower and motor. If abnormal noise or temperature is found, stop the machine for maintenance in time to find out the cause of the fault and the corresponding treatment methods.
