Research on replacement optimization of belt conveyor drive device in Xinjing Mine
In view of the long service life of the driving device of Lunan partition belt conveyor in the main coal flow transportation system of Xinjing Mine,various problems often occur.Under the premise of ensuring the normal operation of the main coal flow transportation system,the driving device is replaced.According to the actual situation of Xinjing Mine,the optimization scheme was studied,and the replaced drive device was selected and analyzed.Finally,it was determined that the'permanent magnet direct drive electric drum+frequency conversion soft start'was used to replace the original drive device.The practice shows that the application effect of the replaced driving device in this design is good,and the installation and operation debugging of the equipment are completed by using the 3 d time of mine maintenance,which has no effect on the normal operation of the transportation system and ensures the safe and efficient mining of the coal mine.
