Usually, because of the long-term operation of the mine fan, its bearings will have a lot of heat due to the long-time rotation and mutual friction, so there will be a lot of heat, so the phenomenon of equipment high temperature is formed, and the bearing performance changes caused by high temperature, which is easy to cause bearing deformation. Therefore, how should we prevent this situation and make it more stable How about its operation?
When the fan of mine fan does not stop, it can rotate the propeller of the air mist fan, and appropriately extend the exhaust speed of the tail, so as to increase the negative pressure of the fan inlet at very low temperature. The operation instruction is determined by standard operation, and the technical parameters are strictly limited. It is used to measure the displacement and pressure regulation deformation of the C-1 pipe inlet of Keelung heat exchanger. When the exhaust measurement of the C-1 pipe inlet is less than 430 ° C, the negative gas of mine fan is strictly controlled.
When the live recording in the main station is not activated and can be activated immediately, the auxiliary transmission of mine fan is set. The fan slides at low temperatures to ensure uniform heating of the main optical axis. A contingency plan is needed to ensure a stable use of power outages. The combustion gas temperature sensor is added at the inlet of mine fan. After closing, the inspection door of the C1 cylinder shall be opened, forced cooling shall be stopped, and inspection shall be conducted at the same time.
For the long-term operation of mine fan, in order to ensure that its working state can meet the needs of the underground operation, we need to carry out flaw detection on it. At that time, there were many detection methods. You can choose the method according to your own situation, and you must use the time-consuming and labor-consuming but effective method.
