Today we introduce the problems encountered in the daily maintenance.
1, under normal circumstances, due to copper damage, iron damage and other reasons, the motor of paper making equipment will have a certain amount of heat in the daily operation process, with the increase of load and speed, the temperature will be higher and higher, and the bearing of the motor for a long time in a high temperature situation, will affect the service life of the motor.
2, the motor in the process of operation will produce a lot of heat, usually in order to heat will use wind blades for ventilation and cooling. However, in the process of ventilation, the dust in the air will adhere to the lubricating oil, which will affect the working performance of the lubricating oil. We can use the sealing method to isolate the lubricating oil from the outside world and reduce the impact of impurities on the bearing.
3, DC motor maintenance, DC motor can produce a wide range of stepless speed change, in the paper industry as a paper machine drag equipment to be applied, DC motor structure is more complex, maintenance requirements are relatively high, for the choice of brush and brush maintenance is more important, improper selection will have a greater impact on the motor. Under normal circumstances, the selection of brushes should be strictly in accordance with the surrounding speed of the commutator, brush current density and other indicators to choose, first select the type of brush, in combination with the rated voltage, current and operation mode of the motor to select the type of brush.
