FST-RP-938781Q Hydraulic Oil Filter Element:
This type of the filter is used in 70 / 70 ECO series of Parker high pressure pipeline filters. The filter element is made of stainless steel woven mesh with high temperature, high pressure and chemical stability. It also reduces the pressure difference of filter core and makes the filter element have high filtration efficiency and stability. The price of the product has a competitive advantage. The inherent strength of the Filter Material and both sides have strong structural support, allowing a wide range of pressure fluctuations. The inherent strength of the material of the filter element and the strong structural support on both sides of the filter element allow a wide range of pressure difference fluctuations.
The inherent strength of the filter material and both sides have strong structural support, allowing a wide range of pressure fluctuations. according to different requirements, we can use stainless steel mesh, sintered felt filter and so on. The filtering accuracy can be selected from 1 to 50 microns and so on.
Characteristics and advantages:
The filter element of 938781Q series instead of PARKER has the same size and can completely replace the original product and achieve the original filter effect.
This type of filtration material is widely used in chemical, food and beverage, mining and pharmaceutical industries. With its square hole, high flow rate and relatively large filtration area, stainless steel mesh filter experienced relatively low pressure drop in the filtration process. The inherent strength of the filter material and both sides have strong structural support, allowing a wide range of pressure fluctuations. according to different requirements, we can use stainless steel mesh, sintered felt filter and so on. The filtering accuracy can be selected from 1~50 microns and so on.
(1) A new filter material is made for the filter element. The multi-layer filtration structure ensures the ability of separation of high contamination and dirty pollution, uniform texture, corrosion resistance and fatigue resistance.
(2) Innovating longitudinal joint technology and perfectly joining the end of filter material, especially under different loads, the effective value can prevent suspended particles from entering the filter zone from the dirt area.
(3) In the operation of filter element, the static electricity can be derived below the safe value, and the continuous formation of black carbon or the formation of silt oil can be excluded.
(4) Used the stainless steel wire mesh and sintered fiber medium, low resistance and large dust capacity.
(5) Germany imported composite filter folding machine to increase the effective filter area.
(6) Oil and temperature resistant cyclopropyl resin adhesive. The seal is firm.
(7) Thickened steel plate skeleton. Strong pressure drop resistance.
(8) To leave the factory after passing the inspection. The quality is reliable.

FST-RP-938781Q filter element instead of PARKER hydraulic Oil Filter element execution standard:
ISO2491 filter-rupture resistance experiment:
The test of resistance to rupture of filter element belongs to the strength test of the filter element itself. The filter element is generally subjected to external force by the pressure difference limit after carrying the dirt in the filter shell. The inner skeleton is the main support of the filter layer under the limit pressure difference of the filter element, and the collapse of the skeleton will lead to the collapse of the filter layer.
ISO2492 filter element structural integrity experiment:
The significance of the requirement of the integrity of the filter element structure, the filter material is very good, the filter material is broken or made incomplete in the process of making the filter element, the incomplete phenomenon mainly manifests in: the filter material is damaged, the end cover is not glued strictly, the filter material butt joint is not strict and solid. It will greatly affect the original filtering accuracy.
ISO2493 filter element the compatibility betwee material and liquid experiment:
The compatibility test between filter element and working fluid is mainly a validation test of the properties of raw materials used in the process of making filter elements, such as compatibility with petroleum, water diol, water-oil emulsion and liquid with high water content. PTFE seals are standard configurations and can be used in conjunction with industrial phosphate, diesters and specific synthetic materials.
ISO3726 filter element experimental method of the end load:
The end load test of the filter element mainly tests the ability of bearing the axial mounting force, the strength, the axial load, the flattening strength and so on.
ISO3724 filter element the determination of fatigue characteristics:
The test of the fatigue characteristics of the filter element is the test of the life of the filter element. The filter element works in the hydraulic system, withstanding the reciprocating and alternating fluid flow of the system and the pressure impact of the working flow. Under this impact, if the filter element has accumulated pollutants and established a greater pressure difference, then the pressure of the filter layer withstanding the fluid flow will be greater.
ISO3968 filter element determination of flow characteristics and the pressure difference:
The pressure drop flow characteristic is usually an assessment of the filter, but in fact, it mainly evaluates the flow rate and resistance of the filter core. Of course, in the design of filter assembly, there are flow and
bypass problems in the channel design of the shell. But after all, it is not the main problem, the main problem is the filter, so the standard mainly checks the filter, not the filter.
