Railway Power Fuel Assurance
A Northeast Railway Bureau has jurisdiction over lines located at the northernmost part of China, spanning Heilongjiang, Inner Mongolia, and other provinces. As a major artery of Northeast railway transport, its operating environment faces harsh winter cold. This project aimed to upgrade the diesel supply system of its key locomotive depot.
In high-latitude, extreme-cold railway transport, fuel quality directly relates to transport safety:
Extreme cold operation challenges: Heilongjiang winter temperatures are extremely low, requiring equipment to operate stably under ultra-low temperature conditions and preventing pipe freeze-blockage caused by low temperatures.
Balancing high flow and precision: Locomotive single fueling volumes are large, requiring filtration equipment to maintain 40m³/h high flow while achieving micron-level filtration precision, which ordinary filter cartridges struggle to balance.
High-value asset risk: Modern diesel-electric locomotives are expensive, and injector pump wear caused by poor-quality diesel results in high repair costs and loss of transport capacity.
Large fuel turnover: The locomotive depot's daily fueling volume is large, requiring filters with high dust capacity to reduce operational interruptions from frequent cartridge replacement.
Jingyuan custom-developed a 40m³/h dedicated locomotive fuel purification system for the Railway Bureau:
High-flow structure: Using a parallel multi-cartridge large-capacity housing design, ensuring 40m³/h ultra-high flow at relatively low differential pressure without affecting locomotive fueling time.
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.
Customized cold-proof design: For the Heilongjiang climate, the equipment features enhanced low-temperature-resistant seals and cold-resistant reliability of the electrical system.
Staged filtration: Using multi-stage staged filtration to effectively intercept rust and suspended impurities generated during bulk fuel storage and transport.
Since the system was put into production, it significantly improved the fuel quality control level of the locomotive depot. The unplanned maintenance rate of locomotive injection systems decreased noticeably. The 40m³/h efficient purification capacity effectively meets the busy scheduling demands of the depot, achieving efficient fueling while ensuring fuel cleanliness, providing solid assurance for the safety and efficiency of high-latitude railway transport.
In the bitter cold of Heilongjiang, fuel reliability is the lifeline of locomotives. Jingyuan's 40m³/h system solved the dual challenge of high-speed fueling and fuel cleanliness. Since installation, fuel-related engine failures have decreased significantly, giving us more confidence in harsh winter operations.
