Concrete Logistics Fuel Purification
A Liaoning concrete company is an enterprise serving local large-scale infrastructure projects. The company owns 60 concrete mixer trucks, equipped with HPCR engines that demand high fuel quality, representing typical precision power assets.
The enterprise encountered equipment reliability issues while pursuing fuel cost optimization:
Fuel quality fluctuation: The diesel purchased by the enterprise has fluctuating quality, containing relatively high levels of mechanical impurities and gums.
Damage to high-precision engines: The HPCR system is sensitive to impurities. Micron-level impurities in the fuel cause frequent wear and seizure of injector nozzles.
High repair costs: Frequent replacement of injector nozzles and fuel circuit components generates high repair costs, undermining the cost optimization efforts.
Affected delivery schedules: Vehicles frequently return to the plant due to fuel system failures, reducing concrete delivery capacity and creating breach-of-contract risks.
A 10m³/h diesel purification system was installed on the outbound fueling line of the company's own fueling station:
Multi-stage purification: Given the high impurity content in the fuel, the system employs high-flow, high-precision staged filtration to effectively intercept mechanical impurities and gums.
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 dispensed fuel is clear, transparent, and meets cleanliness standards.
Flow rate matching: The 10m³/h flow rate matches the dispensing speed of the fleet's internal fueling machines, ensuring that 60 mixer trucks can be refueled without additional queuing.
By introducing the Jingyuan purification system, the enterprise achieved a balance between "cost optimization" and "equipment safety." The cleanliness of purified diesel improved significantly, and the engine failure alarm frequency decreased markedly. Currently, the injector nozzle replacement frequency for the 60 mixer trucks has dropped to the normal maintenance range, and the annual savings on repair costs effectively cover the equipment investment, achieving good economic returns.
Managing a fleet of 60 mixer trucks involves high costs. To control expenses, we purchased diesel with fluctuating quality, but this led to extensive injector nozzle damage. Since installing the Jingyuan 10m³/h system on the station's fueling line, the cleanliness of fuel from the dispensing nozzle has significantly improved. Our repair orders have been drastically reduced, and the mixer trucks can now operate normally on construction sites.
