Plate and frame oil purifier is a commonly used mechanical filtration equipment, mainly used to remove solid impurities and moisture from oil. Its technical indicators are an important basis for measuring equipment performance and work efficiency. The following are the main technical indicators of plate and frame oil purifiers:
- Flow rate: usually expressed in liters per minute (L/min) or cubic meters per hour (m³/h), indicating the amount of oil processed per unit time.
- Common range: 50 L/min to 500 L/min.
- Processing volume: The total amount of oil processed in a single time, usually in liters (L) or cubic meters (m³).
- Filtration accuracy: refers to the minimum particle size that the oil purifier can filter, usually expressed in microns (μm).
- Common range: 1 μm to 50 μm.
- High-precision oil purifiers can reach less than 1 μm.
- Filtration level: According to the filtration accuracy, it is divided into coarse filtration, medium filtration and fine filtration.
- Rated working pressure: The pressure range of the oil purifier during normal operation, usually expressed in megapascals (MPa) or bar.
- Common range: 0.3 MPa to 0.6 MPa.
- Maximum working pressure: The highest pressure that the equipment can withstand. Exceeding this pressure may cause equipment damage.
- Material: Usually high-strength plastic, cast iron or stainless steel.
- Quantity: The number of filter plates and filter frames determines the filtration area and filtration efficiency.
- Common number: 10 to 30 pairs.
- Size: The size of the filter plate and filter frame affects the amount of oil processed at a single time.
- Common size: 200 mm × 200 mm to 600 mm × 600 mm.
- Material: Wood pulp filter paper, synthetic fiber filter paper or mixed filter paper are usually used.
- Filter accuracy: The accuracy of the filter paper directly affects the filtering effect.
- Common accuracy: 1 μm to 50 μm.
- Replacement frequency: Regularly ｒｅｐｌａｃｅ according to the degree of oil contamination and the amount of filtration.
- Power: The power of the motor driving the oil pump, usually expressed in kilowatts (kW).
- Common range: 0.75 kW to 7.5 kW.
- Voltage: Usually 220V or 380V, selected according to the equipment model and regional standards.
- Applicable oil temperature: The oil temperature range that the oil purifier can handle.
- Common range: 10°C to 80°C.
- Heating function: Some oil purifiers are equipped with heaters to reduce oil viscosity and improve filtration efficiency.
- Dehydration efficiency: the proportion of water that the oil purifier can remove for water-containing oil.
- Common range: 90% to 99%.
- Dehydration method: remove water by adsorption on filter paper or heating evaporation.
- Dimensions: length, width and height of the equipment, usually expressed in millimeters (mm).
- Weight: the overall weight of the equipment, usually expressed in kilograms (kg) or tons (t).
- Noise level: the noise level when the equipment is running, usually expressed in decibels (dB).
- Common range: ≤75 dB.
- Sealing performance: The sealing performance of the equipment directly affects the filtering effect and the risk of oil leakage.
- Automation level: Some high-end equipment is equipped with an automatic control system, which can realize automatic filtering, automatic slag discharge and other functions.
- Oil type: Applicable to transformer oil, lubricating oil, hydraulic oil, turbine oil, etc.
- Oil viscosity: The viscosity range of oil that the equipment can handle, usually expressed in centistokes (cSt).
- Overload protection: The equipment is equipped with an overload protection device to prevent motor damage.
- Pressure protection: The equipment is equipped with a pressure gauge and a safety valve to prevent excessive pressure.
Summary
The technical indicators of the plate and frame oil purifier include filtration capacity, filtration accuracy, working pressure, filter plate and filter frame specifications, filter paper performance, motor power, working temperature, moisture removal capacity, equipment size and weight, etc. When selecting equipment, these indicators should be comprehensively considered according to actual needs (such as oil type, pollution level, processing volume, etc.) to ensure that the equipment can operate efficiently and stably.
