YZP crane motor is composed of stator frame, winding and insulation material, rotor, bearing and end cover on both sides, which is relatively simple. it has that characteristic of large overload capacity, high impact toughness, wide speed regulation range, stable operation and the like, and is suitable for the frequency conversion speed regulation transmission device of the hoisting equipment and the metallurgical auxiliary industrial equipment which operate in short time or intermittently, start and brake frequently and rotate positively and reversely, have overload and obvious vibration and impact; With high-precision sensors, high-precision closed-loop operation can be achieved.
YZP crane motor damage, the vast majority of maintenance workers are not fine daily inspection caused by, as long as adhere to the daily maintenance, can avoid these unnecessary trouble. Check the size and change of working current of YZP lifting motor during daily patrol, and see if there is water seepage and dripping around, which will cause low penetration of motor insulation and burn down.
It also depends on whether there are items that affect the ventilation and heat removal environment around the YZP lifting motor; Check whether the fan end cover, fan blade and motor outside are too dirty and must be cleaned; To ensure its cooling heat removal effect. Listen to the operation of the YZP lifting motor sound is abnormal, can use a screwdriver or listening stick and other auxiliary tools, close to the motor on both sides to listen.
If often listen, not only can find YZP lifting motor and drag equipment bad vibration, even internal bearing oil more and less can judge, so as to make timely add bearing oil or replace bearing corresponding countermeasures. With the arm model YZP lifting motor around the temperature, in the case of a good premise, the temperature at both ends will generally be less than the temperature of the middle winding section. If the overall temperature of the YZP lifting motor is high, it is necessary to solve the problems of load, equipment and ventilation of the motor in combination with the working current.
When the YZP crane motor stops working, it is necessary to measure the phase-to-ground or phase-to-phase insulation resistance with insulation meter frequently, and compare with the test results of last month, so as to find the insulation defects in time. If the insulation defects are found, bake it with drying lamp to improve the insulation, so as to avoid burning the motor due to low insulation penetrating the winding.
