When using the air flotation machine in winter, the operator should check whether the water inlet of the sewage is frozen every day at work. If it is frozen, it should be cleaned up immediately to avoid the abnormal operation of the machine due to the freezing. Check the water pump carefully before going to work, and consider adding lubricating oil when it is found that the operation is not sensitive. You should also check the tightness of the packing, check the tightness of the valve, and check the oil volume of the air compressor. If the oil volume is significantly reduced, it needs to be refilled.
The slag scraper is an important part of the air flotation machine. If the slag scraper does not operate normally, the use of the entire air flotation machine will be affected. Wear, whether it can be transmitted normally. The air filter is a key part of the air compressor. It is easy to freeze in winter. Therefore, you should carefully check whether the ice is formed before starting the machine. If there is ice, it should be removed immediately. When starting up, listen to the air compressor for noise and abnormal heat. If there is any abnormal phenomenon, stop the machine for inspection to avoid mechanical accidents during the use of the air flotation machine.
Before starting the machine in winter, carefully check the valves and pipelines, check whether the valves are in the correct switch, whether there is ice, whether the pipelines are blocked, whether there is leakage or bending. The storage tank for storing the coagulant is also the equipment that should be checked before starting the machine. The daily inspection is mainly to observe whether there is ice or damage. During the regular inspection, a small sample should be taken for sample analysis to determine whether the coagulant is abnormal.
