Introduction to the working principle of lubricating oil purifier

Lubricating oil purifiers play a key role in maintaining the operating efficiency and service life of various types of mechanical equipment. The equipment ensures the cleanliness of the oil by effectively removing contaminants such as dirt, particles, and water from the lubricating oil, thereby ensuring the normal operation of the engine and other mechanical systems.

By continuously maintaining the quality of the lubricating oil, the purifier can significantly reduce mechanical wear, reduce the friction coefficient, and inhibit the risk of corrosion, ultimately extending the service life of the equipment's core components.

Regular use of lubricating oil purifiers can not only improve the reliability of equipment operation, but also reduce operating costs by reducing maintenance frequency and preventing sudden failures, which fully demonstrates its important value in the industrial field.

Working principle of the lubricating oil purifier

The lubricating oil purifier achieves efficient purification through four key links: particle filtration, agglomeration, separation and oil drainage. The various systems work together to ensure the overall treatment effect.

Particle filtration system

As the first step of the purification process, the system uses a multi-stage filtration device to remove solid pollutants in the oil, including:

1. Dust impurities

2. Metal debris

3. Mechanical wear particles

Common filter types:

Mesh filter丨Drum filter丨Magnetic filter

Precision filtration can effectively prevent abrasive particles from scratching and wearing mechanical parts, and is the first line of defense for equipment protection.

Coalescing system

The oil, after preliminary filtration, enters the coalescence treatment stage, with the main functions:

√ Capture micron-sized water droplets through special coalescence elements

√ Promote the aggregation of small oil droplets to form large oil droplets

√ Significantly improve the subsequent separation efficiency

2. This process is particularly suitable for treating emulsified oil and can effectively break the oil-water mixing state.

Separation system

Dual separation technology is used in this stage:

Gravity sedimentation: Use the density difference between oil and water to achieve natural stratification

Centrifugal separation: Generate centrifugal force through high-speed rotation to enhance the separation effect

Professional centrifugal separators can achieve a water removal rate of more than 99%, ensuring the quality of the oil.

Oil drainage system

As the final treatment link, its core functions include:

→ Automatic monitoring of pollutant accumulation

→ Accurate control of the opening and closing of the sewage valve

→ Ensure that the separated substances are completely discharged from the system

The intelligent drainage design can completely avoid secondary contamination of the purified oil and ensure the continuous and stable operation of the system.

Application of lubricating oil purifier in light oil and turbine oil

In response to the special needs of different industrial scenarios, lubricating oil purifiers provide professional solutions for light oil and turbine oil systems to ensure that key equipment obtains the best lubrication protection.

Turbine oil purification solution

Given the characteristics of large rotating equipment such as gas turbines and steam turbines, professional oil purifiers provide:

Online moisture content monitoring function

Submicron particle filtration capability

Antioxidant protection system

Real-time oil quality analysis

Typical cases show that the use of professional purification solutions can extend the overhaul cycle of turbines by 30-40% and reduce annual maintenance costs by more than 25%.
