Oil Feed Line Assembly Industry knowledge
In high-pressure and heavy-load mechanical systems such as automotive gearboxes, industrial hydraulic gearboxes, and aero-engines,?stable oil delivery?is the core prerequisite for the continuous operation of equipment. However, the industry has long faced three major pain points: the scattered assembly of traditional pipelines is time-consuming and difficult to maintain; mixed high and low-pressure oil supply is prone to local pressure overload and oil leakage; the temperature and pressure resistance of pipelines is insufficient, and they are difficult to be compatible with multiple types of lubricating media, which directly affects the operational stability and service life of equipment.
As an integrated oil delivery unit, the Oil Feed Line Assembly precisely addresses the above industry challenges. With its modular structure, zoned oil supply design and other core technologies, it has become a core solution for high-reliability oil delivery in various fields.

1. Core Product Definition

The Oil Feed Line Assembly is an integrated pipeline unit that integrates core components such as?oil pumps, precision pipelines, sealed joints, and flow valves. It mainly undertakes the directional, quantitative, and constant-pressure delivery of lubricating oil or fuel in mechanical systems. As the "core vein" connecting power sources and lubrication/power components, it is widely applicable to various scenarios such as automotive transmission, industrial hydraulics, and aerospace power.

2. Core Differences Between Traditional Pipelines and Oil Feed Line Assembly

Comparison Dimension Traditional Split-type Pipeline Oil Feed Line Assembly
Assembly Method Scattered components are spliced on-site and require multiple adjustments Modular pre-integration, ready for immediate installation without secondary adjustment
Oil Supply Mode Single pressure circuit, prone to local overload High and low-pressure dual-chamber zoned oil supply, adapting to the differentiated needs of multiple components
Medium Compatibility Only suitable for specific oil products, pipeline replacement is required for replacement Compatible with mineral oil, synthetic oil, and special lubricating oil without pipeline modification
Leakage Risk Multiple joints are spliced with many sealing points and high risk Integrated formed pipeline with special seals, reducing leakage rate by more than 80%

3. Industry Application Scenarios

The product can cover the full-scenario oil delivery needs from civil industry to high-end equipment, including:
  • Automotive Field: Lubricating oil delivery for automatic gearboxes and turbocharging systems
  • Industrial Field: Heavy machinery hydraulic gearboxes and precision machine tool lubrication systems
  • Aerospace Field: Dual-path delivery of fuel and lubricating oil for small aero-engines


    Precisely Matching Industry Oil Delivery Needs

    The functional design of the Oil Feed Line Assembly fully meets the core demands of oil delivery in various fields, and each function is realized by its exclusive structure:
    1. Zoned Precision Oil Supply
      The product pump body adopts a?high-pressure chamber + low-pressure chamber?dual-chamber independent design. It can realize directional delivery according to the oil supply pressure requirements of different components in the system (e.g., the high-pressure chamber is suitable for power components, and the low-pressure chamber is suitable for lubrication components). This avoids the pressure imbalance problem of traditional single-loop oil supply and improves oil utilization efficiency.
    2. Multi-medium Compatible Delivery
      The inner wall of the pipeline is treated with special anti-corrosion and wear-resistant processes, which can be compatible with mineral-based lubricating oil, fully synthetic lubricating oil, and aviation-grade special lubricating media. It can adapt to the medium needs of different equipment without replacing the pipeline, greatly reducing equipment adaptation costs.
    3. Convenient Disassembly, Assembly and Maintenance
      Adopting a modular integrated design, core components such as driving gears, driven gears, and guide wheel mounts are pre-assembled into an integrated unit. On-site installation can be completed only by docking with equipment interfaces, and the components have high interchangeability. In case of failure, they can be replaced quickly, reducing the equipment downtime for maintenance by more than 60%.

      Key Technical Indicators and Industry Advantages of the Product

      The core performance of the Oil Feed Line Assembly has passed rigorous industry standard tests (such as ISO 4038 burst pressure test and ISO 16750-3 pulse life test). The specific indicators are shown in the table below:
      Performance Indicator Product Parameter Industry Standard Requirement Performance Advantage
      Temperature Resistance Range -40℃~180℃ -20℃~120℃ Adaptable to extreme high and low-temperature working conditions, such as automotive transmission systems in alpine regions and hydraulic equipment beside high-temperature industrial furnaces
      Pressure Resistance Level High-pressure chamber ≤35MPa, low-pressure chamber ≤10MPa General pipeline ≤20MPa Meets the high-pressure oil supply needs of aero-engines and heavy hydraulic equipment without pressure attenuation
      Pulse Life ≥1 million pressure cycles ≥500,000 cycles Far exceeds industry standards and is suitable for industrial equipment scenarios with high-frequency start-stop
      Sealing Performance No leakage for 1000h under 35MPa pressure No leakage for 500h under 20MPa pressure Adopting integrated formed sealed joints to completely solve the leakage problem under high-pressure working conditions
      Adaptable Pipe Diameter φ10~φ80 φ15~φ60 Covers more specifications of equipment interfaces with stronger adaptability

      Frequently Asked Questions (FAQ)

      1. Q: Can this product be adapted to turbocharging systems of different brands of automobiles?
        A: Yes. The product adopts a standardized interface design, and the pipeline has a multi-diameter adaptability of φ10~φ80. It can dock with oil interfaces of turbocharging systems of different brands by replacing special joints. At the same time, the dual-chamber oil supply design can precisely match the high and low-pressure oil needs of the turbocharging system.

      2. Q: What sealing points should be paid attention to during installation?
        A: Two points should be noted during installation: first, ensure that the sealing gasket at the joint matches the working condition (pressure-resistant gaskets for high-pressure chambers and oil-resistant gaskets for low-pressure chambers); second, a pre-pressure test should be carried out after pipeline docking (it is recommended to hold pressure at 50% of the rated pressure for 30 minutes first), and then put into formal use after confirming no leakage.

      3. Q: What treatments are required when switching between different oil products for the product?
        A: Due to the full oil compatibility of the product, there is no need to replace the pipeline when switching oil products. Only simple flushing of the pipeline interior (circulating flushing with new oil for 2-3 times) is required to complete the medium switching, avoiding performance attenuation caused by mixing different oil products.

      4. Q: What is the regular maintenance cycle of the product? Which components need to be checked key?
        A: The maintenance cycle under normal working conditions is 6000 hours, and it is recommended to shorten it to 4000 hours under high-frequency start-stop or extreme working conditions; during maintenance, it is necessary to focus on checking the integrity of sealed joints, the sensitivity of pressure regulating valves, and whether there is corrosion or wear on the inner wall of the pipeline. If component aging is found, the modular unit can be directly replaced without overall disassembly of the machine.
