Vacuum oil purifier and plate oil purifier are two common oil filtration equipments, which have significant differences in working principle, applicable scenarios and functional characteristics. The following is a detailed comparison between the two:
| Oil purifier type | Working principle |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | Use the vacuum environment to lower the boiling point of water, evaporate the water and gas in the oil, and remove solid particles through precision filtration. |
| Plate oil purifier | Filter the solid particles in the oil through filter paper or filter cloth, and use the compression effect of the filter plate and filter frame to achieve filtration. |
| Oil purifier type | Main functions |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | 1. Efficiently remove water and gas. <br>2. Remove solid particles. <br>3. Suitable for purifying oil products with high water content. |
| Plate oil purifier | 1. Mainly removes solid particles. <br>2. Suitable for oil products with more solid pollutants. |
| Oil purifier type | Applicable oil products |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | Oil products that need to remove water and gas, such as turbine oil, insulating oil, hydraulic oil, and lubricating oil. |
| Plate oil purifier | Oil products that need to remove solid particles, such as lubricating oil, gear oil, and hydraulic oil. |
| Type of oil purifier | Filtration accuracy |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | Usually 1-10μm, combined with precision filtration, high-precision purification can be achieved.|
| Plate oil purifier | Usually 5-30μm, suitable for coarse filtration and medium-precision filtration.|
| Type of oil purifier | Processing capacity |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | Strong processing capacity, suitable for large-scale continuous operation.|
| Plate oil purifier | Moderate processing capacity, suitable for small and medium-scale operations. |
| Type of oil purifier | Equipment structure |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | Including vacuum pump, heater, precision filter, condenser and other components, the structure is relatively complex. |
| Plate oil purifier | Including filter plate, filter frame, filter paper or filter cloth, clamping device and other components, the structure is relatively simple.|
| Type of oil purifier | Operation and maintenance |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | The operation is relatively complex, and components such as vacuum pump, heater and filter need to be maintained regularly. |
| Plate oil purifier | Simple operation, maintenance mainly involves replacing filter paper or filter cloth, cleaning filter plates and filter frames.|
| Type of oil purifier | Cost |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | The equipment cost and operating cost are high, suitable for occasions with high requirements for oil purification. |
| Plate oil purifier | The equipment cost and operating cost are low, suitable for occasions with limited budget or low purification requirements.|
| Type of oil purifier | Applicable scenarios |
|----------------|-----------------------------------------------------------------------------|
| Vacuum oil purifier | 1. Power industry (steam turbine, water turbine, transformer, etc.). <br>2. Petrochemical industry (compressors, pumps, etc.). <br>3. Manufacturing industry (hydraulic systems, gearboxes, etc.). |
| Plate oil purifier | 1. Machinery manufacturing industry (lubricating oil, gear oil, etc.). <br>2. Mining industry (hydraulic oil, lubricating oil, etc.). <br>3. Small and medium-sized factories. |
| Comparison items | Vacuum oil purifier | Plate oil purifier |
|------------------|------------------------------------------|--------------------------------------|
| Working principle | Vacuum dehydration + precision filtration | Filter paper or filter cloth filtration |
| Main functions | Removal of moisture, gas and solid particles | Removal of solid particles |
| Applicable oils | Turbine oil, insulating oil, hydraulic oil, etc. | Lubricating oil, gear oil, hydraulic oil, etc. |
| Filtration accuracy | 1-10μm | 5-30μm |
| Processing capacity | Strong | Moderate |
| Equipment structure | Complex | Simple |
| Operation and maintenance | Complex | Simple |
| Cost | High | Low |
| Applicable scenarios | High purification requirements (such as power and petrochemical industries) | General purification situations (such as machinery manufacturing and mining industries) |
- Choose a vacuum oil purifier:
- If the oil contains a lot of water and gas, and the purification accuracy requirements are high.
- Applicable to industries such as power and petrochemicals that have strict requirements on oil quality.
- Choose a plate oil purifier:
- If the oil is mainly contaminated by solid particles, and the purification requirements are not high.
- Suitable for cost-sensitive industries such as machinery manufacturing and mining.
Through the above comparison, you can choose the appropriate oil purifier type according to your specific needs. If you are not sure how to choose, you can consult the oil purifier supplier or professional technicians for advice.
