Braking System: The Safe Guarantee Of Electric Mine Locomotives

Coal mine electric locomotive operating method can be summed up to start, stop, speed, reversing, braking. Among them, the braking system played a crucial role in the entire coal mine locomotives. The braking force of the car is an artificial resistance to slow down or stop the running train. Underground electric locomotives are generally only locomotives have braking devices, tub no brake device, so the train braking force can only be considered by the locomotive braking. So, how can we better control the speed of the electric car to ensure safe driving it? 

The stepless speed regulation drive is used with the driver controller and speed governor. It can make the diesel engine smoothly raise, decelerate and stabilize at a given speed so as to achieve the purpose of stepless speed regulation. In the coal mine electric locomotive company to use this device in stepless speed locomotive, stepless speed locomotive is a 5 tons of electric locomotives, 5 tons of electric locomotives, general type, safety type, explosion-proof special type three. There are two kinds of speed regulation. Stepless speed regulation locomotive Main characteristic: The whole machine structure is reasonable, explosion-proof performance is reliable, start smooth, save energy consumption. Organic speed control locomotive is the use of battery strings in parallel, the motor string and parallel and magnetic field weakened. Speed regulation for the 7 level, the car starting a more smooth, no significant impact. Explosion-proof and reliable performance, good quality, simple structure, easy maintenance, welcomed by users. I supply the company’s 5-ton battery locomotives small-scale compact locomotives and traction traction is strong and features, with the tonnage of DC motor traction motor vehicle 1.5 times. Reasonable structure and layout, safe and reliable driving operation, maintenance and other characteristics of small. At the same time frequency converter also has undervoltage, overvoltage, overheating, overcurrent, speeding and other protection functions, and brake deceleration charging function and full speed control and electrical braking functions. To maximize the use of locomotive safety, reduce or even avoid the occurrence of security incidents. Of course, in order to be able to use coal mine electric locomotives for a longer period of time, regular maintenance and repair of the brake system is also very important, in each succession before using the electric locomotive, to check it, check the brake system parts damage and Wear, once found damaged parts, must be replaced, because the brake is reliable to determine the safe driving. In the relaxed state, the brake shoes should be placed in a concentric position with the tires to prevent the braking system from tilting in the vertical plane. According to the size of the brake shoe wear to adjust the screw at the lower end of the connecting rod, so that the brake shoe and wheel gap between the maintenance of 2-3 within the range, so that you can quickly brake. The brake screw bearing and pin connection every five days will be coated with oil. - See more at: http://www.chinamachine-export.com/7410#sthash.U42xR7mm.dpuf
