Lubricating oil filter device selection method

Lubricating oil filtration systems are primarily used to remove impurities (such as metal particles, dust, moisture, and oxidation products) from lubricating oil, extending oil life and protecting equipment. How should you choose a lubricating oil filtration system based on the filtration principle and application scenario?

Key Factors in Lubricating Oil Filtration System Selection

1. Contamination Type:

- Solid particles → Mechanical/Magnetic/Electrostatic Filtration.

- Moisture → Vacuum/Coalescing/Adsorption Filtration.

- Oxidation Products → Activated Carbon/Centrifugal Filtration.

2. Filtration Fineness:

- Standard Equipment: 10-50 μm.

- High-Precision Equipment: 1-5 μm (e.g., aviation hydraulic oil).

3. Flow Rate Requirements: 

Small flow rates (<100 L/min) can be handled with a portable system, while large flow rates require an online system.

4. Maintenance Cost: 

Frequency of filter element replacement, energy consumption, and manual cleaning requirements.

Typical Applications

- Construction Machinery: Centrifugal + Magnetic Filter (to address metal wear).

- Power Industry: Vacuum Dehydration + Precision Filtration (for turbine oil maintenance). - Food Industry: Stainless Steel Cartridge Filters (FDA-compliant).

- Marine: Coalescing and Separation (for treating lubricating oil contaminated by seawater).

Depending on specific needs, various filtration technologies can be combined (e.g., "magnetic + centrifugal + vacuum" three-stage filtration). For critical equipment, online monitoring (particle counting, moisture testing) is recommended to optimize maintenance cycles.
