Industrial lubricating oil filtration equipment parameters

Industrial lubricating oil filtration equipment parameters

Industrial lubricating oil filtration equipment is used to remove particulate pollutants, moisture, gas and oxidation products in the oil, extend the life of the oil, and ensure the stable operation of the equipment. The following is a detailed introduction to the classification, working principle, selection recommendations and mainstream brands of industrial lubricating oil filtration equipment.

Key selection parameters

When purchasing industrial lubricating oil filtration equipment, you need to pay attention to the following core parameters:

1. Filtration accuracy (μm)

- Coarse filtration: 10~50μm (suitable for pre-filtration).

- Fine filtration: 1~10μm (suitable for gear oil, hydraulic oil).

- Ultra-fine filtration: ≤1μm (suitable for precision bearings, turbine oil).

2. Flow rate (L/min)

- Small equipment: 20~100 L/min (single-machine lubrication system).

- Medium-sized equipment: 100~500 L/min (centralized lubrication system).

- Large equipment: 500~2000 L/min (steel plants, power plants).

3. Water removal capacity

- Ordinary equipment: ≤100ppm (coalescence separation type).

- High-efficiency equipment: ≤50ppm (vacuum dehydration type).

4. Applicable oils

- Mineral oil/synthetic oil (PAO, ester oil).

- High viscosity oil (such as gear oil) needs to be heated to reduce viscosity.

5. Automation level

- Manual type: economical, suitable for small-scale maintenance.

- Fully automatic type: with PLC control, suitable for continuous operation.

Typical application scenarios

| Industry | Applicable equipment type | Main functions |

|----------------|-----------------------------|--------------------------------------|

| Electricity | Vacuum oil filter | Turbine oil dehydration, particle filtration |

| Steel | Centrifugal oil filter | Metal chip separation of rolling mill lubricating oil |
