Many rotating machines in thermal power plants are driven by motors, such as: fans, water pumps, oil pumps, coal conveying belts, electric valves and the like. The number of the on-site motors in the factory is large, most motors are free of winding temperature measuring points and temperature protection, a motor cooling fan cover is fixed on a motor body through three bolts, when the motor runs, due to equipment vibration, moisture rust, acid-base sulfur-containing gas corrosion and the like, the fixing bolts of the cooling fan cover are broken frequently, the cooling fan cover and the cooling fan are in collision and abrasion, blades of the cooling fan are broken, a motor cooling system loses cooling effect, the motor is at high temperature, and a motor stator is damaged in insulation and burns. And hidden danger is brought to the safe and stable operation of the motor.
Thus, some problems arise as follows:
(1) Although the motor cooling fan increases the motor running time, the failure rate increases year by year;
(2) The motor cooling fan cover falls off, so that the motor is burnt, and the economic loss is increased year by year;
(3) After the motor cooling fan cover is detached, the fan runs to throw the fan cover off, so that unsafe accidents of objects striking people are easily caused;
(4) In some oil system and hydrogen system areas on site, sparks are generated due to falling off of the cooling fan cover and collision and grinding of the fan and the motor, so that potential safety hazards such as deflagration and explosion are increased;
(5) The motor is burnt out because of the cooling fan cover drops and leads to the motor insulation, will cause the unable normal operating of each system such as coal, water, vapour, oil of power plant, will directly threat the safety of unit when serious, causes the generating set non-to stop, brings huge economic loss for the enterprise production.
