LYC series high-efficiency impurity removal oil filter

LYC series two-stage filtering and impurity removal oil filter is a device used to filter and purify oil and remove impurities. The following is its relevant introduction:

1. Working principle

Two-stage filtering process:

First-stage filtration: mainly used to intercept larger particles of impurities, such as metal debris, large particles of dust, etc., to prevent these large particles of impurities from damaging the subsequent fine filtration links or clogging the filter element too quickly, and play a role in preliminary filtration and protection.

Second-stage filtration: further remove smaller particles of impurities and possible residual water, etc. After the second-stage fine filtration, the oil reaches a higher cleanliness requirement and meets the equipment operation standard for oil cleanliness.

Pressure filtration method: usually adopts a motor-driven gear pump and other methods to apply a certain pressure to the oil, so that the oil is forced to pass through various levels of filters under pressure to ensure the efficiency and effect of filtration.

2. Structural composition

Filtration system:

Coarse filter: generally installed at the oil suction port, as the front end of the first-stage filtration, used to filter out larger particles of impurities, protect the oil pump and extend the service life of the whole machine.

Two-stage fine filter: It is the core component for two-stage filtration and impurity removal. According to different precision requirements, the appropriate filter element material and filter aperture are selected to achieve different degrees of filtration effect. For example, the first-stage fine filter can filter out larger particle impurities, and the second-stage fine filter can filter out fine particles or water.

Power system:

Motor: Provides power for the oil filter and drives the oil pump to operate. Its power is selected according to factors such as the model of the oil filter and the processing flow.

Oil pump: Such as gear pump, it has the characteristics of low noise, strong self-priming ability, and smooth operation. It is responsible for extracting oil from the oil tank and delivering it to the filtration system.

Protection device:

High-pressure pipeline overflow protection device: When the pressure in the pipeline exceeds the set value, the overflow protection device is turned on to prevent excessive pressure from causing damage to the hydraulic system and ensure the safe operation of the equipment.

Thermal relay protection: Overload protection for the motor. When the current of the motor exceeds the rated value due to excessive load, the thermal relay will operate to cut off the power supply of the motor to prevent damage to the motor.

Other parts:

Housing: The quick-open structure allows operators to quickly and easily open the upper cover when they need to replace the filter element or perform equipment maintenance, without the need for any tools, which improves work efficiency.

Control panel: Pressure gauges and other instruments are usually installed on it to continuously indicate the operating status of the system, such as pressure values, etc., and to display the degree of contamination of the filter element, so that operators can promptly understand the working status of the equipment and determine whether the filter element needs to be replaced.

3. Technical parameters

Flow parameters: Different models of LYC series oil filters have different rated flow rates, the most common of which are 32L/min, 50L/min, 63L/min, 100L/min, etc. The appropriate model can be selected according to the actual use scenario and the demand for oil treatment volume.

Pressure parameters:

Rated pressure: Generally around 0.6MPa, some models may be different.

Initial pressure loss: Usually ≤0.02MPa. The lower the pressure loss, the less obstruction the oil filter has to the flow of oil during the filtration process, and the lower the energy consumption.

Filtration accuracy:

Coarse filtration accuracy: The common coarse filtration accuracy is 100μm, which is used to intercept larger particle impurities.

First-level fine filtration accuracy: There are usually different grades such as 10μm, 20μm, 40μm, etc. to choose from, which is determined according to the requirements for oil cleanliness.

Second-level fine filtration accuracy: Common ones are 3μm, 5μm, 10μm, etc., which are used to further remove tiny particles and impurities.

Motor parameters: The power of the motor also varies with different models, such as 0.75kW, 1.1kW, 2.2kW, etc. The power size is related to the processing capacity and work efficiency of the oil filter.

4. Application field

Industrial field:

Power industry: Used for filtering and purifying lubricating oil and insulating oil of steam turbines, water turbines, transformers and other equipment in power plants, removing impurities and moisture in the oil, ensuring the normal operation of the equipment, and extending the service life and maintenance cycle of the equipment.

Metallurgical industry: Filter hydraulic oil and lubricating oil in the hydraulic system and lubrication system of rolling mills, continuous casting machines and other equipment in steel plants to prevent impurities from causing wear and failure to the hydraulic components and lubricating parts of the equipment.

Chemical industry: Filter various oils in the chemical production process, such as heat transfer oil in reactors and lubricating oil in compressors, to ensure the cleanliness of the oil and the continuity and safety of chemical production.

Mechanical manufacturing field:

Machine tool industry: Used in the hydraulic system and guide rail lubrication system of various machine tools to filter impurities such as metal chips and abrasive particles in the oil, improve the processing accuracy and stability of machine tools, and reduce the maintenance cost of equipment.

Engineering machinery industry: Filter hydraulic oil and transmission oil of engineering machinery such as excavators, loaders, cranes, etc., to adapt to the harsh working environment of engineering machinery, and prevent hydraulic system failures and mechanical parts damage caused by oil contamination.

Transportation field:

Automobile industry: In the process of automobile manufacturing and maintenance, it is used to filter automobile engine oil, transmission oil, brake fluid, etc. to improve the performance and reliability of automobiles.

Aerospace field: High-precision filtration of aircraft fuel, hydraulic oil, lubricating oil, etc. to meet the strict requirements of aviation equipment for oil cleanliness and ensure flight safety.
