Product representation

I. Review of products

The Donaldson filter element is a filtering product produced by Donaldson in the USA. As a well -known filter brand, Donaldson, thanks to its advanced technologies and strict quality control, makes this filter element widely used in the world. It can effectively filter impurities in all types of media, ensure stable operation of the equipment and extend its service life.

Work parameters

1 working environment: used for various working environments, such as acid fatty hydraulic oil, emulsion, water - glycol, general hydraulic oil, phosphate ester of hydraulic oil, and so on.

2. Material: It takes many types of high -quality materials, including fiberglass filter paper - BN, stainless steel, woven nets - W, wood mass of filter paper - P, stainless steel of sophisticated nets - V, etc. Various materials are suitable for various working conditions and various applications. Various materials are suitable for various working conditions and filtering requirements, for example, the filter paper made of fiberglass has high filtration accuracy and a strong muddy intake; Stainless steel has good corrosion resistance and mechanical strength.

3 working pressure: the operating pressure range is 21 bar - 210 bar, which can satisfy the needs of various pressure levels.

4. Working temperature: it can work normally in the temperature range -30 ℃ ~ +110 ℃, and can adapt to all types of harsh temperature conditions of the environment.

5 sealing material: a fluoride ring and nitrile rubber are usually used as sealing material, they have good oil resistance, resistance to aging and tightness to guarantee the absence of a cartridge leak in the working process.

6. Filtering: filtering accuracy covers 1, 3, 6, 12, 25 ...... μm and other levels that can be accurately selected in accordance with the actual needs to achieve effective interception of impurities of various sizes of particles.

7. The filtration coefficient: x ≧ 100, which means that it can effectively separate impurities from the working environment and significantly improve the cleanliness of the medium.

Thirdly, the characteristics of the structure

1. Minor filtering structure: the cartridge takes a multi -layer filtration design, various materials and the structure of the filter layer with each other, from rough to thin filtration, a layer by a layer, effectively removing the smallest particles in water, sediment, rust and other impurities to guarantee that filtered environment to achieve a high degree of purity of standards.

2. Support and protection: internal support and protection of the network is provided to increase the structural strength of the cartridge, so that it can remain stable and not easily deformed or damaged in harsh conditions of high pressure and high flow rate, thereby prolonging the service life.

3 The design with a small distance between the folds: this design helps to remove dust, which facilitates the removal of dust and other contaminants that adhere to the surface of the filter element, ensures the permeability and efficiency of filtering the filter element, and also reduces the problem of increased pressure drop due to clogging.

4 A uniform clearance of the filter material: provides 99% efficient filtration area and efficiency, makes filtering uniformly throughout the filtration area, reduces differential pressure on the filter element, increases the stability and reliability of filtration.

5. Strong connection: both end lids are connected to the filter material with metal or polyurethane end covers, which are technically formulated with special cartridge glue, with severe resistance to break, ensuring the integrity and tightness of the general structure of the cartridge.

Testing standard

1 Verification of the stability of the filter for the gap: in accordance with the ISO 2941 standard, to make sure that the filter element will not break when exposed to a certain pressure, which ensures its safe use in high -pressure media.

2. The structural integrity of the cartridge: is checked in accordance with the ISO 2943 standard to make sure that the structure of each part of the cartridge is tightly connected, without cracks, holes and other defects to ensure its normal filtration function.

3 Verification of compatibility of the filter element: also in accordance with the ISO 2943 standard, check the compatibility of the material of the filter element and the working environment with each other to avoid damage to the filter element or reduce the filtration effect due to the chemical effect.

4 Filtering characteristics: are tested in accordance with the ISO 4572 standard to clarify the filtration ability and effectiveness of the filter for impurities of various particles.

5. The characteristics of the differential pressure of the filter: are measured in accordance with the ISO 3968 standard to understand the change in the differential pressure of the filter at various flow speeds and provide recommendations for the design and operation of the system.

6. Testing the characteristics of the cost - differential pressure: also in accordance with the ISO 3968 standard, the dependence curve between the consumption and differential pressure is obtained as a result of the test to optimize the consumption and configuration of pressure in the system.
