Railway Fuel Multi-Stage Purification
A Southwest Railway Bureau Group Co., Ltd. is responsible for railway transport within and around the province. As a radiation center facing South Asia and Southeast Asia, its diesel locomotives play a key role in cross-national transport and heavy-haul transport in mountainous areas.
The Railway Bureau faces challenges of diversified flow rate demands and complex environments in fuel management:
Fueling efficiency bottleneck: On busy route segments, locomotive station turnaround time is short, and traditional filtration equipment has insufficient flow rate. Forcibly increasing flow rate reduces precision, making it difficult to meet 50m³/h-level rapid fueling demands.
High altitude and humid conditions coexist: The climate is complex, with rainy and humid mountainous conditions affecting fuel stability, and the high-altitude environment imposes higher requirements on the pumping and sealing performance of the filtration system.
Locomotive power safety: Diesel locomotives demand high fuel cleanliness when climbing heavy-haul grades in mountainous areas. Fine impurities causing power loss may trigger safety hazards.
Dispersed maintenance system: Due to scattered station locations, there is an urgent need for a highly reliable, easy-to-maintain standardized equipment system to reduce cross-regional maintenance costs.
Jingyuan provided the Railway Bureau with a staged configuration customized purification solution:
Differentiated flow rate strategy:
50m³/h custom skid: Using ultra-large-volume housing and multi-stage parallel technology to meet hub station rapid supply.
12m³/h custom equipment: Meets the daily purification needs of distributed stations, ensuring consistent fuel quality across the entire line.
Polymer Rigid Composite Membrane: Using Jingyuan® polymer rigid composite membrane, leveraging the oleophilic-hydrophobic properties of the membrane material, it efficiently intercepts particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear, transparent, and meets cleanliness standards.
Intelligent differential pressure control: Equipped with an intelligent differential pressure early warning system, accurately indicating filter cartridge status during high-intensity operations, ensuring uninterrupted fueling.
Reinforced design: Optimized electrical systems and anti-corrosion coatings for high-altitude environments, ensuring long-term stable equipment operation under harsh mountainous conditions.
The comprehensive deployment of 11 systems built a solid fuel safety barrier for the Railway Bureau. In particular, the application of the 50m³/h equipment effectively shortened single locomotive fueling time, improving the depot's turnaround efficiency. Depot data statistics show that after installing Jingyuan equipment, the average service life of diesel locomotive injectors was effectively extended, and the locomotive failure rate caused by fuel contamination decreased noticeably.
In the complex geographical environment of the Southwest, fuel cleanliness is critical to railway safety. Jingyuan's solution, especially the 50m³/h high-flow units, effectively met our dual demands for speed and quality. After deployment at 11 stations, the incidence of engine-related issues decreased noticeably. This is a key upgrade for our locomotive fleet.
