Factors causing insufficient traction in mining locomotives

Insufficient traction in mining locomotives can be attributed to various factors. Understanding these factors is crucial for identifying and addressing the underlying issues to ensure optimal performance. Here are some of the key factors:

1. Deterioration of the speed regulator: When the speed regulator deteriorates, it can lead to a lower voltage output, resulting in reduced traction force.

2. Faulty current transformers: The performance of current transformers plays a critical role in accurately measuring and controlling the current flow. A faulty current transformer can affect the traction capabilities of the locomotive.

3. Severe degradation of the filtering capacitors: The filtering capacitors are responsible for maintaining stable power supply and reducing electrical noise. When these capacitors severely deteriorate, it can impact the traction force of the locomotive.

4. Malfunctioning control drive box (ND300): The control drive box is a crucial component in managing the locomotive's traction and speed control. Any malfunction or defect in this component can result in reduced traction performance.

5. Defective IGBT modules: The Insulated Gate Bipolar Transistor (IGBT) modules are responsible for controlling the power flow in the locomotive's traction system. Defective IGBT modules can lead to insufficient traction force.

6. Faulty electric motor: The electric motor's performance directly affects the locomotive's traction capabilities. A faulty motor can result in reduced power output and traction force.

7. Poor welding of track return lines: Inadequate welding of the track return lines can cause disruptions in the electrical circuit, leading to a decrease in traction force.

Identifying and rectifying these factors requires a systematic approach, including regular inspections, maintenance, and timely replacements of faulty components. By addressing these issues promptly, mining locomotives can maintain optimal traction performance, ensuring efficient and safe operations.

It is essential to consult with experts and follow manufacturer guidelines for troubleshooting and resolving traction-related issues in mining locomotives. Proper maintenance and adherence to best practices will contribute to the overall productivity and longevity of the locomotive fleet.

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.
