What are the performance indicators of oil purifiers?

The performance indicators of the oil purifier are important parameters to measure its filtering effect, operating efficiency and service life. Understanding these indicators will help you choose the right oil purifier and optimize its operation. The following are the main performance indicators of the oil purifier:

1. Filtration accuracy

- Definition: The minimum particle size that the oil purifier can filter, usually in microns (μm).

- Significance: The higher the filtration accuracy, the stronger the ability of the oil purifier to remove tiny impurities.

- Common range: 1μm, 3μm, 5μm, 10μm, etc., ｓｅｌｅｃｔ according to equipment requirements.

2. Flow rate

- Definition: The volume of oil processed by the oil purifier per unit time, usually expressed in liters/minute (L/min) or cubic meters/hour (m³/h).

- Significance: The larger the flow rate, the faster the oil purifier processes the oil.

- Influencing factors: oil viscosity, filter element clogging degree, pump power, etc.

3. Working pressure

- Definition: The pressure inside the system when the oil purifier is running, usually expressed in megapascals (MPa) or bar.

- Significance: Working pressure affects filtration efficiency and filter life.

- Common range: 0.1-0.6MPa (depending on the type of equipment).

- Significance: The lower the cleanliness, the cleaner the oil.

- Target value: Depending on the equipment requirements, it is usually required to reach NAS 1638 level 6 or higher.

- Significance: The ability of the oil purifier to remove water from the oil, usually expressed in ppm (parts per million).

- Significance: The stronger the dehydration capacity, the better the oil purifier can treat water-containing oil. - Common range: can reduce water content to less than 100ppm (or even lower).

6. Degassing capacity

- Definition: The ability of the oil purifier to remove air and other gases from the oil, usually expressed as a percentage of gas content.

- Significance: The stronger the degassing capacity, the lower the gas content in the oil, avoiding cavitation and unstable equipment operation.

- Common range: can reduce gas content to less than 0.1%.

7. Processing viscosity range

- Definition: The range of oil viscosities that the oil purifier can handle, usually expressed in centistokes (cSt).

- Significance: Oils of different viscosities require different filtration parameters and equipment configurations.

- Common range: 10-400cSt (depending on the type of equipment).

8. Heating power (if applicable)

- Definition: The power of the oil purifier heater, usually expressed in kilowatts (kW). - Significance: Heating power affects oil temperature control, which in turn affects filtration efficiency and dehydration effect.

- Common range: 3-30kW (depending on the equipment model).

9. Vacuum degree (if applicable)

- Definition: The vacuum degree of the vacuum oil purifier during dehydration and degassing, usually expressed in Pascals (Pa) or millibars (mbar).

- Significance: The higher the vacuum degree, the better the dehydration and degassing effect.

- Common range: -0.08MPa to -0.098MPa.

10. Filter element dirt holding capacity

- Definition: The total amount of impurities that the filter element can hold, usually expressed in grams (g).

- Significance: The higher the dirt holding capacity, the longer the service life of the filter element.

- Influencing factors: filter element material, filtration area, oil contamination degree, etc.

11. Operating Noise

- Definition: The noise level generated by the oil purifier when it is in operation, usually expressed in decibels (dB).

- Significance: The lower the noise, the quieter the equipment runs and the less impact it has on the environment.

- Common range: 60-80dB (depending on the type of equipment).

- Significance: The total power of the oil purifier motor and pump, is usually expressed in kilowatts (kW).

- Significance: The higher the power, the greater the processing capacity of the equipment, but also the higher the energy consumption.

- Common range: 1-30kW (depending on the equipment model).

- Common range: 1-30kW (depending on the equipment model).

- 13. Equipment Weight and Size

- Definition: The overall weight and dimensions of the oil purifier.

- Significance: Weight and size affect the ease of transportation, installation and movement of the equipment.

- Common range: Weights range from tens of kilograms to several tons, and the dimensions vary depending on the model. 14. Automation degree

- Definition: The automation control capability of the oil purifier, including automatic start and stop, automatic drainage, automatic alarm and other functions.

- Significance: The higher the automation degree, the easier the operation and the less manual intervention.

- Common functions: PLC control, touch screen operation, remote monitoring, etc.

15. Service life

- Definition: The expected service life of the oil filter under normal use and maintenance.

- Significance: The longer the service life, the better the economic efficiency of the equipment.

- Influencing factors: material quality, design rationality, maintenance, etc.

Summary

The performance indicators of the oil filter include filtration accuracy, flow rate, working pressure, cleanliness, dehydration capacity, degassing capacity, processing viscosity range, heating power, vacuum degree, filter element dirt holding capacity, operating noise, power, equipment weight and size, degree of automation and service life. These indicators jointly determine the filtration effect, operating efficiency and scope of use of the oil filter. When selecting and using the oil filter, these performance indicators should be comprehensively considered according to specific needs and working environment to ensure that the equipment can operate efficiently and stably.
