Explosion-proof 8-Ton Battery Accumulator Locomotive for Coal Mine

Explosion-proof 8-Ton Battery Accumulator Locomotive for Coal Mine

What factors will affect the braking effect of battery electric locomotives?

There are two main factors affecting the braking effect of battery electric locomotives, one is the braking device itself, and the other is the size of the adhesion coefficient.

If the brake device is not in place. For example, the screws, nuts or brake shoes are seriously worn and not replaced in time; or the suspenders, connecting rods or push rods are skewed and not repaired in time.

The coefficient of adhesion has a great influence on the magnitude of the adhesion traction force. The adhesive traction not only determines how much cargo the battery electric locomotive can pull, but also determines the maximum braking force of the battery electric locomotive. Therefore, if the adhesion coefficient is low, the braking force of the battery electric locomotive is also low, and the braking effect is naturally not good. When driving, you can first use the sand spreading device to assist the braking of the battery electric locomotive, and then check the specific reasons for the low adhesion coefficient after parking. For example, there is a lot of oil on the wheels and tracks, or the battery electric locomotive is overloaded and so on.

The above are some common reasons for the poor braking effect of battery electric locomotives.

7. Proving factory online-visiting

Mining Locomotive test
1.Before Running the locomotive,carry out gear debugging, lighting, gear, and brake adjustment etc.To ensure the normal operation of the locomotive.
2.Carry out a tensile test before leaving the factory to ensure the load performance of the locomotive meets the standard. Our design standards generally exceed the national standard by 10%-20%.
3.Carry out different type running test before leaving the factory to ensure the performance and normal operation of the whole locomotive. It can adapt to various harsh conditions under simulated working conditions.

Motor test
The motor has to go through many inspection procedures before leaving the factory, and each motor has to be carried out with load running experiments.
Explosion-proof motors are carried out with water pressure test.
All the test of motor is to ensure that can adapt to harsh working conditions.

1. A good feedback of our lithium battery locomotive from a client of Latin America
2. In order to solve the exist problems of lead-acid batteries. More than 30 lead-acid battery electric locomotives in this large mining were changed into lithium battery electric locomotives, which improved the work enthusiasm and production efficiency of employees, reduced costs,and more environment-friendly.
3. The mining rock drill car designed by Sunward Co., has a small size and simple structure, so the space for placing the lithium battery on the body is very limited.
According to the limitation size, our company design a lithium power supply power plan, which
perfectly solves the problem of lithium power supply space.
In order to adapt to the special industrial and mining environment and improve transportation efficiency, a batch of 2.5-ton lithium battery electric locomotives are designed to Myanmar Clients.
