Tianjin mine explosion-proof power distribution box order custom explosion-proof motor bearing maintenance

The use and maintenance of the explosion-proof motor sliding bearing ( 4) Before the first start the motor, explosion-proof motor on the smooth, need to filling in the appropriate smooth oil bearing; About external loop oil motor, it is necessary to ensure oil supply system device debugging, the end of work. Choose appropriate smooth oil and the correct filling, is the key of the sliding bearing work, should refer to the following content: (1) smooth oil brand of choice. Any low foam and high quality mineral oils with good anti-aging ability, just can reach the requested smooth oil viscosity can be used. Smooth oil viscosity can be selected according to table 1. The commonly used smooth oil for L - TSA46 and L - TSA32。 (2) on the smooth, explosion-proof electric motor during fuel should guarantee the oil level height in the sliding bearing oil standard height of 1/2 - Between two thirds. About external pressure explosion-proof motor cycle oil, oil ring gear, used to prevent the external supply of circulating oil shortage, to ensure the safe operation of the equipment. Should pay special attention to: should regulate the pressure of bearing oil inlet, adhere to a certain flow, make the oil bearing internal stability in oil standard height of 1/2 - Between two thirds, beyond this level will form the bearing oil. 01 - Between 5 mpa, when stop gauge value will rise slightly. (3) with oil pool heater motor, if the motor used in the winter in the north, in the 1 h before starting, must turn the heater, and hour, pay attention to the oil pool of oil temperature, to ensure the oil temperature not to surpass 50 t. 1 bearing temperature monitoring in the explosion-proof motor operation, needs to stop monitoring the temperature of the sliding bearing, but should pay attention to not only by discriminant bearing down on the running state of bearing temperature, more important is bearing temperature change condition, often should check the bearing temperature change status and record, assuming that found the bearing temperature rise, and compared to before the numerical value of similar conditions are abnormal, must stop its reason and cleaning. * is allowed to use temperature of bearing, different industries have different requests, the relevant specification rules is not the same. But from a technical point of view, bearing * allows the use of temperature and the bearing alloy materials and casting processing quality, oil temperature measuring point position, smooth performance.
