Dawn hydraulic oil filter element LH0240D010BN/3HC model

The following introduces the hydraulic oil filter element from multiple aspects:

Definition and Function

The hydraulic oil filter element is a key component in hydraulic systems, mainly used to filter pollutants in hydraulic oil, such as metal particles, dust, rubber impurities, etc. By removing these impurities, the cleanliness of hydraulic oil can be ensured, the wear, corrosion, and failure of hydraulic components can be reduced, and the reliability and service life of hydraulic systems can be improved.

Common types

1. paper filter element

• featureMade by folding filter paper, it has high filtration accuracy and can effectively intercept small particles; Relatively low cost and easy replacement.

• Application scenariosWidely used in general industrial hydraulic systems, such as machine tools, construction machinery, etc.

2. Stainless steel sintered filter element

• featureMade by sintering stainless steel powder, it has high strength, high temperature resistance, corrosion resistance, and good filtration performance and pollutant holding capacity; Can be cleaned and reused.

• Application scenariosSuitable for hydraulic systems with high filtration requirements and harsh working environments, such as metallurgy, mining and other industries.

3. Chemical fiber filter cartridge

• featureHigh filtration accuracy, strong oil flow capacity, and low pressure loss; Good chemical stability, not easily affected by additives in hydraulic oil.

• Application scenariosCommonly used in precision hydraulic systems, such as aerospace, electronic equipment, and other fields.

4. Metal mesh filter cartridge

• featureSimple structure, affordable price, and large oil flow capacity; The filtering accuracy is relatively low.

• Application scenariosGenerally used as a coarse filter, it is used for the oil suction port of hydraulic systems to protect key components such as oil pumps.

performance metrics

1. filtration accuracyThe minimum particle size that the filter element can filter out, usually expressed in micrometers (μ m). The higher the filtering accuracy, the smaller the particles that can be filtered out. For example, in some precision hydraulic systems, filter cartridges with a filtration accuracy of 3 μ m or even higher may be required.

2. Pollutant carrying capacityThe mass of pollutants that the filter element can hold before reaching the specified pressure difference. The larger the pollutant holding capacity, the longer the service life of the filter element, and the longer the replacement cycle.

3. pressure lossThe pressure drop generated when hydraulic oil passes through the filter element. The smaller the pressure loss, the better the oil flow capacity of the filter element, and the smaller the energy loss of the hydraulic system.

4. filtration efficiency: Indicates the filtering ability of the filter element for particles of different sizes, usually expressed as a percentage. For example, a filtration efficiency of 99% means that the filter element can filter out 99% of particles of a specific size.

Select key points

1. System RequirementsSelect the appropriate filter element based on the working pressure, flow rate, temperature and other parameters of the hydraulic system. For example, in high-pressure systems, it is necessary to choose a filter element with good pressure resistance performance; In high-temperature environments, it is important to choose filter cartridges that are resistant to high temperatures.

2. filtration accuracyDetermine the appropriate filtration accuracy based on the precision requirements and working conditions of the components in the hydraulic system. Generally speaking, a coarse filter with lower filtration accuracy can be used for the suction port of the oil pump, while a fine filter with higher filtration accuracy needs to be used for the return port of the system and the inlet of important components.

3. installation dimensionsEnsure that the installation dimensions of the filter element match the housing of the filter, including parameters such as outer diameter, inner diameter, height, etc. If the size does not match, it may cause the filter element to be unable to be installed or sealed tightly, affecting the filtration effect.

4. Brand and QualityChoose filter cartridges with reliable brand and quality to ensure their performance and service life. You can refer to the usage experience and evaluation of other users to choose products with good reputation.

Maintenance and replacement

1. regular inspectionRegularly check the working status of the filter element and observe whether there are any blockages, damages, or other issues on the surface of the filter element. It is possible to determine whether the filter element needs to be replaced by observing the differential pressure gauge of the filter. If the differential pressure exceeds the specified value, it may indicate that the filter element is clogged and needs to be dealt with in a timely manner.

2. Cleaning or replacementFor washable filter cartridges, such as stainless steel sintered filter cartridges, regular cleaning can be performed to remove surface contaminants. But the cleaning frequency should not be too many, so as not to affect the performance of the filter element. For non washable filter cartridges, such as paper filters, they should be replaced promptly when they reach the end of their service life or when the filtering effect significantly decreases.

3. correct installationWhen replacing the filter element, ensure that it is installed correctly and sealed properly to avoid leakage. At the same time, attention should be paid to the installation direction of the filter element. Some filter elements have specific installation requirements and must be installed according to the instructions.
