The Single Line Lubrication System operates on a centralized supply principle, driven by a lubrication pump (electric, Hydraulic or pneumatic) that delivers lubricant to a single main pipeline. The lubricant is then distributed to each lubrication point through branch pipelines and metering valves. Each metering valve is pre-set to deliver a fixed volume of lubricant, ensuring that each lubrication point receives accurate and uniform lubrication. The system adopts a simple pipeline design, which not only reduces installation difficulty but also makes it easy to check and maintain, and can quickly locate faults when abnormalities occur.
Core Components
The system is composed of high-quality, durable components, all manufactured by Dingyi to meet global industrial standards. Key components include:
Single Line Injector/Metering Valve: Available in 1-6 outlet channels, with a metering range of 0--1.31cc per cycle; made of high-strength steel, with good sealing performance and wear resistance, suitable for long-term stable operation.
Lubrication Pump: Optional electric (10-30VDC/220VAC) or pneumatic (0.2-0.8MPa) or Hydraulic drive , ensuring stable lubricant supply even under high-pressure conditions.
Changeover Valve: Optional changeover valves, enabling seamless switching between lubrication circuits for multi-equipment or multi-point lubrication needs.
Control & Monitoring Accessories: Optional pressure switches, level sensors, and alarm devices, providing real-time monitoring of system operation and alerting for faults (e.g., low lubricant level, blockage).
Dingyi’s single Line Lubrication System is designed with a compact and simple structure, making it ideal for medium and heavy-duty equipment and scenarios where multi-point lubrication is required but installation space is limited. It is widely applied in various industrial fields, including:
•Construction Machinery: excavators, loaders, road rollers, forklifts, and small to medium-sized engineering vehicles — suitable for lubricating bearings, gears, and hydraulic components.
•Mining equipment: Large excavators, crawler cranes, large road roller..
•Industrial Equipment: Machine tools, small to medium-sized conveyors, compressors, pumps, and gearboxes — providing stable lubrication for key moving parts in factory production lines.
•Special Equipment: Small cranes, environmental protection equipment, and municipal engineering machinery — customized pipeline design to fit limited installation space and complex lubrication requirements.
Product Advantages
•Simple Structure & Easy Installation: Adopts a single main pipeline design, with fewer components, simple layout, low installation difficulty, and reduced pipeline material and construction costs.
•Easy Maintenance & Fault Location: The pipeline is simple and clear, convenient for daily inspection and maintenance; when a fault occurs, it can quickly locate the problematic lubrication point or component, reducing maintenance time and costs.
•Durable & Reliable: All components are made of high-quality materials, with strong corrosion resistance, wear resistance, and adaptability to harsh working conditions (high temperature, dust, vibration), ensuring long-term stable operation.
•Energy-Saving & Efficient: Low power consumption, automatic lubrication, reducing manual lubrication labor intensity, improving lubrication efficiency, and avoiding lubrication omissions.
•Customizable: According to customer needs, we can customize the number of lubrication points, metering volume, pump type, and pipeline length to match different equipment and application scenarios.
