Selection factors of plate and frame oil purifier

Plate and frame oil purifier is a common oil filtration equipment, mainly used to remove solid particle impurities in oil products. Its selection needs to consider multiple factors to ensure that the equipment can meet specific filtration needs. The following are the key factors for selecting plate and frame oil purifier:

1. Oil characteristics

- Oil type:

- Determine the type of oil to be filtered (such as lubricating oil, hydraulic oil, gear oil, etc.).

- Viscosity:

- The viscosity of the oil affects the filtration efficiency and the selection of the oil purifier. High viscosity oil may require a larger filtration area or higher pressure.

- Operating temperature:

- The operating temperature range of the oil determines the material of the oil purifier and the temperature resistance of the seal.

2. Filtration requirements

- Filtration accuracy:

- ｓｅｌｅｃｔ the appropriate filtration accuracy (such as 1μm, 5μm, 10μm) according to the purification requirements of the oil.

- Processing volume:

- ｓｅｌｅｃｔ a suitable flow rate (such as L/min or m³/h) according to the processing volume of the oil.

- Type of contaminants:

- Determine the type of major contaminants in the oil (such as solid particles, water, etc.). Plate and frame oil purifiers are mainly used to remove solid particles.

3. Equipment performance

- Filter area:

- The larger the filter area, the higher the filtration efficiency. ｓｅｌｅｃｔ the appropriate filter area according to the viscosity of the oil and the concentration of contaminants.

- Working pressure:

- The working pressure range of plate and frame oil purifiers is usually 0.1-0.6MPa. ｓｅｌｅｃｔ the appropriate working pressure according to the viscosity and filtration accuracy of the oil.

- Filter plate and filter frame material:

- Common materials include cast iron, stainless steel and polypropylene (PP). ｓｅｌｅｃｔ the appropriate material according to the corrosiveness of the oil and the operating temperature.

- Filter paper or filter cloth:

- ｓｅｌｅｃｔ the appropriate filter paper or filter cloth material according to the filtration accuracy and oil characteristics.

4. Degree of automation

- Manual operation:

- Manual plate and frame oil purifiers are low-cost, but the operation is more cumbersome.

- Semi-automatic operation:

- Semi-automatic oil purifiers have some automation functions (such as automatic pressing of filter plates), which makes operation more convenient.

- Fully automatic operation:

- Fully automatic oil purifiers have functions such as automatic pressing and automatic slag unloading, which are suitable for large-scale continuous operation.

5. Equipment size and mobility

- Equipment size:

- Choose the appropriate equipment size according to the on-site space.

- Mobility:

- If the oil purifier needs to be moved frequently, choose a mobile device with wheels.

6. Power requirements

- Power type:

- Choose the appropriate power type (such as 220V, 380V) according to the on-site power conditions.

- Power:

- Choose the appropriate power supply according to the power requirements of the equipment's heating, pumping and other functions.

7. Environmental conditions

- Ambient temperature:

- When used in extreme temperature environments, choose equipment with strong adaptability and high stability.

- Humidity:

- When used in high humidity environments, choose equipment with good moisture resistance.

8. Brand and service

- Brand:

- Choose a well-known brand of oil purifier to ensure the quality and performance of the equipment.

- After-sales service:

- Choose a supplier that provides comprehensive after-sales service to ensure equipment maintenance and technical support.

9. Budget

- Equipment cost:

- Choose a suitable oil purifier according to the budget, balancing performance and price.

- Operating cost:

- Consider the operating costs such as the energy consumption of the oil purifier and the frequency of filter paper or filter cloth replacement.

Plate and frame oil purifier selection steps

1. Determine the type and characteristics of the oil:

- Understand the viscosity, operating temperature and pollutant type of the oil.

2. Determine the filtration requirements:

- Determine the filtration accuracy, processing volume and main pollutants.

3. ｓｅｌｅｃｔ equipment performance:

- Choose the appropriate filtration area, working pressure and material according to the filtration requirements.

4. Consider the degree of automation:

- Choose manual, semi-automatic or fully automatic equipment according to the operation requirements.

5. Consider equipment size and mobility:

- Choose the appropriate equipment size and mobility according to the site conditions.

6. Check power requirements:

- Make sure the equipment power matches the site power.

7. Consider environmental conditions:

- Choose equipment that adapts to the site environment.

8. Choose brands and services:

- Choose well-known brands and perfect after-sales service.

9. Evaluate budget:

- Choose the right equipment according to the budget.

The selection of plate and frame oil purifiers needs to comprehensively consider factors such as oil characteristics, filtration requirements, equipment performance, degree of automation, equipment size, power requirements, environmental conditions, brand services and budget. Through reasonable selection, the oil purifier can be ensured to operate efficiently and stably to meet the needs of oil purification. If you are not sure how to choose, you can consult the oil purifier supplier or professional technicians for advice.
