According to usage, mine fans can be divided into two types, one is used as the main fan, the other is used as an auxiliary fan. Of course, it can also be used for ventilation in other environments. Our common mine fan models are K40, K45, and so on, which are better performance fans. The performance of mine fan does not mean that it will not have problems in the process of use, and when the general fault is large, the mining fan will stop directly, so when we use the mine fan, the sudden shutdown shows that there is a fault.
A series of problems have occurred in the operation of Coal Mine Fan, induction fan, and roof fan. Attention should be paid before and after closing. Before the mine fan stops, it enters the small load to stop processing, and then closes the inlet and outlet valves. In the case of forced oil bearings, oil is supplied to the bearings before the spindle is completely stopped. After the aircraft using the cooling water bearing stops, the cooling water valve must stop. For the mine fan transporting harmful gas, attention should be paid to the leakage of shaft parts, and measures should be taken to prevent the loss of gas to the environment. For the mining fan transporting high temperature gas, the gas temperature in the car shell is lower than 100 ℃, so it must be continued.
Of course, axial fans,Centrifugal Fan, induction fans, roof fans and other equipment do not need to stop for a long time. In this way, the rusty parts of the machine should be coated with proper amount of lubricating oil and other rust agents. Countermeasures should be taken for motors and other electrical equipment. The preparation time should not be ignored.
The problem of sudden shutdown of coal mine main fan must be paid attention to. After all, it is used under the mine, so the safety of mine fan is very important. In order to prevent it from failure, regular maintenance must be carried out, and the use method should be correct.
