Metering Device for Industrial Lubrication Systems

Product Specifications

Technical details and manufacturing context for Metering Device

Definition

A metering device is a critical component within an industrial lubrication system responsible for accurately measuring and regulating the precise amount of lubricant delivered to specific points, such as bearings, gears, or slides. It ensures optimal lubrication, prevents over- or under-lubrication, and contributes to system efficiency and equipment longevity. The device operates by creating a controlled restriction or using a positive displacement mechanism (e.g., piston, gear, or diaphragm) to measure a specific volume of lubricant per cycle or unit time. It is typically actuated by system pressure or an external control signal to dispense the measured quantity. Available materials include stainless steel, brass, and engineering plastics. Key parameters include a flow rate range of 0.1–10 L/min, operating pressure of 1.0–1.6 MPa, accuracy class ±2.5% (ISO 1328), temperature range -20–80 °C, viscosity range 10–500 cSt, electrical supply 24 V DC ±10%, output signal 4–20 mA, ingress protection IP65–IP67 (IEC 60529), material 316L (ASTM A240), connection size G1/4–G1 (ISO 228-1), and weight 1.2–2.5 kg. These values are reference ranges; verify model-specific data with the manufacturer. The device is suitable for various industrial applications where precise lubricant dosing is required. It is not a standalone product but a component integrated into larger systems. Proper selection depends on system demand, operating conditions, and compatibility with the lubricant. Always consult the supplier for detailed specifications and installation guidelines.

Working Principle

The metering device operates by creating a controlled restriction or using a positive displacement mechanism (e.g., piston, gear, or diaphragm) to measure a specific volume of lubricant per cycle or unit time. It is typically actuated by system pressure or an external control signal to dispense the measured quantity. The device ensures that each lubrication point receives the exact amount of lubricant required, preventing waste and ensuring optimal performance. The working principle is based on the physical displacement of lubricant, which is independent of pressure fluctuations, providing consistent dosing. The device may be adjustable to vary the output volume, depending on the system's needs. It is designed to operate within specified pressure, temperature, and viscosity ranges to maintain accuracy. The device's internal components are made from materials that resist corrosion and wear, ensuring long service life. The metering device is a passive component that relies on the system's pressure or an external signal to function, making it reliable and easy to integrate into existing lubrication systems.
