  How to disassemble the broken axle of the wheel of a mine electric locomotive   The maintenance of the broken motor axle is a tricky thing for most small and medium mines. Because the assembly of the axle and the shaft is an interference fit, it is difficult to disassemble and disassemble intact and maintain accuracy.   1. Disassembly of the axle The matching interference between the motor wheel shaft and the wheel shaft is large. If a large press is used to force the broken shaft remaining in the shaft to be forced out, it is easy to destroy the wheel shaft size. Moreover, small and medium-sized mine repair plants generally do not have large presses. . In order to facilitate the disassembly of the shaft without damaging the size of the wheel, and to ensure the accuracy and roughness of the wheel, drilling can be used. The specific operation is as follows: Use a drill bit with a price of 18-22~, drill three holes side by side along the diameter direction at the outer shaft end of the

  What is the principle of hydraulic braking   for  the mine electric locomotive ?   Hydraulic oil serves as the carrier of hydraulic braking to transmit force and movement. The use of hydraulic oil can not only complete the work but also maintain and maintain the working parts, which can extend the life of the parts. The working pressure of the hydraulic system is higher than that of the pneumatic system. Under the condition of reaching the same working force, the required hydraulic cylinder diameter is smaller than that of the pneumatic system.   In an explosion-proof electric locomotive with tight space, a smaller space requirement can be more conducive to the placement of components. Because the system is closed, the hydraulic system is less likely to be affected by environmental factors and is relatively stable. The above is the principle of hydraulic braking for the mine electric locomotive. For more to want know, please add my Linkedin ： https://www.linkedin.com/in/sunnlocomotiv

 What are the bake methods of the battery locomotive or trolley locomotive? Basically, there would be three brake types in the mining battery or trolley locomotive. The are Mechanical brake,  Hydraulic brake and air bake. In XIANGTAN YUTONG, 1.5-2.5T: Mechanical Brake;(every locomotive has this basic one) 3-5T:Hydraulic Brake; ≥6T：Air brake.

                    R esistance control VS   IGBT control of  mine electric locomotives     Resistance  and IGBT control are two common speed control methods used in non-coal mine electric locomotives. The main differences of them are working methods, mechanical wear, energy-saving effects, maintenance costs, etc. Details are as follows:   1) Working mode : Resistance is a mechanical speed control method, which controls the speed of the vehicle by changing the resistance value (gear speed control). It has the characteristics of long life, but the maintenance rate is high because the contacts are easy to burn out; while the  IGBT uses the module to control the speed (step-less speed regulation), built-in electronic horn and   control switches for front and rear light, energy-saving and power-saving, e asy to operate, long service life;   2) Mechanical wear: When the electric locomotive uses resistance, there are many wear points , such as the controller , brake shoes, motor and gearbox
