Detailed introduction of product materials
SP130E03B0BE belongs to the long cylinder high-pressure precision fiberglass filter element. The long cylinder structure requires higher requirements for the filter material, support skeleton, and end cap bonding process. It is necessary to avoid defects such as bending under pressure, collapse of the filter layer, delamination of the end cap, and fiber detachment of the long filter element to prevent fine fibers from entering the servo oil circuit and causing damage to the precision valve components.
-Filter material: Multi layer gradient ultra-fine resin cured inorganic glass fiber filter material, using long continuous folding molding process. The outer filter layer preferentially intercepts larger metal impurity particles, while the inner ultrafine glass fiber layer achieves precise capture of 3 μ m small particles. The filter material undergoes high-temperature impregnation and solidification treatment, and the fibers are firmly bonded to each other. Under long-term high-pressure oil flow erosion conditions, fiber peeling and detachment will not occur, preventing fine fibers from entering the oil circuit and causing secondary pollution. The gradient layered pollutant absorption structure allows impurities to accumulate in different filter layers, improving the shortcomings of high-precision filter cartridges with small pollutant absorption and rapid increase in pressure difference. The gradual increase in pressure difference rate effectively extends the service life of the filter cartridge.
-Internal and External Support Skeleton: Thickened punched galvanized carbon steel bidirectional support skeleton, designed with anti bending reinforcement for long tube filter elements, to enhance overall anti extrusion and anti bending capabilities, cope with high-pressure alternating impacts caused by frequent equipment start-up and shutdown, and prevent filter elements from being flattened, bent and collapsed by oil flow when the pressure difference increases. The skeleton adopts a high porosity design, which reduces the initial flow resistance of the filter element while ensuring mechanical strength, and does not interfere with the dynamic response performance of the servo oil circuit.
-Sealing parts: standard NBR nitrile rubber sealing ring, oil resistant and anti-aging, resistant to long-term immersion, swelling and deformation of hydraulic oil, ensure that the filter element and the end face of the filter seat closely fit, and prevent oil bypass short circuit. Support the upgrade of FKM fluororubber seals for special medium scenarios such as high temperature working conditions and phosphate ester fire-resistant oil.
-End cap and bonding process: Machine processed metal end caps, using high-strength two-component adhesives for hot pressing composite molding. The bonding strength between the filter material, skeleton, and end cap has undergone multiple cycles of pressure drop impact testing, and will not peel or crack under high-pressure alternating conditions. All assembly dimensions are 1:1 replica of the original factory standard, with precise disassembly and positioning of the long tube filter element, and smooth assembly on the machine.

We have established an independent factory inspection process for SP130E03B0BE long tube 3 μm precision filter cartridges. Each batch is sampled for pressure resistance testing, sealing testing, and filtration efficiency verification. We focus on controlling quality risks such as long tube filter cartridge delamination, skeleton bending, and fiber detachment to ensure continuous operation reliability on metallurgical and heavy industry sites. As a source manufacturer, we have cut the premium of multi-layer intermediaries for imported brands. We not only support single sample machine testing, but also undertake annual factory maintenance and large-scale bidding procurement for engineering projects. We can customize and upgrade filter and sealing materials according to the customer's on-site media, temperature, and pressure conditions.
Frequently Asked Questions (FAQ)
Q1: What is the reason for the rapid increase in pressure difference of this long tube precision filter element and how to handle it?
A: High precision filter cartridges are highly sensitive to pollutants, and a rapid increase in pressure difference indicates a large load of pollutants in the system; It is recommended to install a pre coarse filter in the front-end, regularly sample and test the oil contamination level, and replace the filter element in a timely manner when the pressure difference reaches 0.20MPa.
Q2: What are the precautions for selecting bypass valves for the SP130 series high-pressure filter?
A: The collapse pressure difference of the filter element is 21 bar, and the opening pressure of the filter bypass valve must be lower than the collapse pressure difference of the filter element; It is not recommended to rely on bypass valves for long-term operation of servo systems. Priority should be given to configuring differential pressure transmitters, and filter cartridges should be replaced in case of differential pressure alarms.
Q3: Can a large servo hydraulic system rely solely on this 3 μm filter element to ensure that the oil cleanliness meets the standard?
A: Cannot rely solely on a single filter element to maintain oil quality for a long time. It is recommended to adopt a graded filtration scheme, which combines coarse filtration before the pump, precision filter element of pressure pipeline SP130E03B0BE, and return oil filtration; Regular oil sample testing to control the generation of pollutants from the source.
