In the field of heavy machinery and electric power industry, the thin oil station is the core unit of the lubrication system, and its filtering performance is directly related to the operating efficiency and life of the equipment. The thin oil station lube oil filter ZNGL02010501 has been designed and optimized in multiple dimensions for the working conditions of large flow and low resistance, achieving the comprehensive goal of high reliability and low maintenance cost.

1. Structural design optimization: from double-barrel parallel connection to modular quick-change mechanism

The traditional thin oil station filter element often causes frequent downtime maintenance due to the single-barrel structure, while the lubricating oil filter element ZNGL02010501 adopts a double-barrel parallel filtration system, and realizes “non-interruption switching” through the linkage design of the pressure balance valve and the reversing valve. The core advantages of this structure are:

Redundant fault tolerance: When the pressure difference of one side of the filter increases due to the accumulation of pollutants, the system automatically switches to the spare filter to avoid the main engine shutdown;

Low torque reversing valve design: By optimizing the valve body flow channel and the sealing surface accuracy, the switching operation torque is reduced by 40%, reducing the intensity of manual intervention;

Modular quick-change interface: The filter element adopts a snap-on installation structure, combined with a standardized sealing ring (nitrile rubber or fluororubber), which can be replaced within 5 minutes, greatly shortening the maintenance time.

This type of design not only solves the problem of oil circuit fluctuations when switching traditional filters, but also reduces turbulent resistance by reducing local flow velocity.

2. Material innovation: composite filter material and gradient filtration technology

In large flow scenarios, the pollution capacity and air permeability of the filter material are key contradictions. The lube oil filter element ZNGL02010501 adopts a metal mesh-glass fiber composite structure, and achieves performance breakthroughs through the following innovations:

Gradient filter layer design: the outer layer is a 60-mesh stainless steel metal mesh to intercept large particle impurities; the middle layer adopts a high-density glass fiber layer to adsorb fine particles; the inner layer is provided with a guide support skeleton to reduce flow resistance;

Compressive strength optimization: through the metal skeleton winding process, the filter material can still maintain structural stability under 21MPa high pressure, avoiding flux attenuation caused by fiber layer collapse;

Improved temperature resistance: the glass fiber layer is treated with silane coupling agent, and the operating temperature range is extended to -20℃~100℃, which is suitable for the operating conditions of the northern cold and high temperature units.

3. Fluid dynamics optimization: from guide structure to intelligent bypass mechanism

In order to reduce the flow resistance under large flow, a 45° oblique guide groove is processed on the inner side of the end cover of the thin oil station filter element ZNGL02010501, so that the oil forms a vortex when entering the filter element, and is evenly distributed to the entire filter surface to avoid local blockage. The multi-layer diffusion filter layer adopts an asymmetric pore distribution strategy. The porosity of the outer filter material is 70%, which decreases to 50% layer by layer inward, achieving graded interception of pollutants and reducing the overall flow resistance.

4. Sealing and reliability design: from static matching to dynamic compensation

Under high-pressure pulsating conditions, sealing failure is the main reason for the decline in filter element performance. The optimization measures for lube oil filter ZNGL02010501 include:

The three-lip sealing structure made of fluororubber material compensates the gap through elastic deformation when the temperature fluctuates, and the leakage rate is less than 0.01mL/min;

Laser welding is used to replace traditional argon arc welding, and the weld strength is increased by 30%, eliminating the risk of high-pressure oil penetrating the weld;

By simulating the 6-level vibration environment of mining machinery, the internal support structure of the filter element is optimized.

The design optimization of the ZNGL02010501 filter element reflects the deep combination of functional requirements and engineering practice: continuity is guaranteed through a double-tube redundant structure, the contradiction between filtration accuracy and flow resistance is balanced with material innovation, and energy efficiency is improved by fluid dynamics analysis. This series of improvements enables the product to demonstrate significant advantages in thin oil stations in power plants, metallurgy and other fields, setting a new benchmark for the reliability of lubrication systems for heavy equipment.
