Sumitomo hydraulic return oil filter element with good quality and good property made of imported materials easy to clean and easy to install to protect the machinery

 

The hydraulic oil filter element is marked on the product sample or nameplate of the manufacturer as the nominal filtration accuracy, but not the absolute filtration accuracy. Only the value measured through the test can indicate the filtration capacity of the filter. The hydraulic oil filter element should also meet the requirements of pressure loss (the total pressure difference of the high-pressure filter is less than 0.1PMa, and the total pressure difference of the return oil filter is less than 0.05MPa), so as to ensure the optimization of flow rate and filter element life. So how should we choose the hydraulic oil filter element correctly?

 

1. Filtering accuracy

 

First of all, according to the needs of the hydraulic system to determine the cleanliness level of the used stains, and then according to the cleanliness level of the table to select the filter filter accuracy. The nominal filtration clarity of the hydraulic oil filter element commonly used in construction machinery is 10 m. Hydraulic servo valve (with 3 m filter element) 16/135 hydraulic proportional valve (with 5 m filter element) 18/1510 general hydraulic components (>10MPa) (with 10 m filter element) 19/1620 general hydraulic components (<10MPa) (with 20 m filter element)

With nominal filtration precision can not truly reflect the cartridge filter ability, therefore, often in under the test conditions prescribed by the filter can be big hard spherical particle diameter as its absolute filtration precision, which directly reflects the new filter filter ability in the early evaluation of hydraulic oil filter is the most important criterion by ISO4572-1981 - e (multipass test) to determine the beta, namely through the oil standard test powder were mixed with multiple loop filter, the oil inlet and the ratio of the number of particles on either side of the oil outlet.

 

2. Flow characteristics

 

The flow rate and pressure drop of the filter element through the oil are important parameters of the flow rate characteristic. The flow rate characteristic test should be conducted according to the iso3968-91 standard to draw the flow rate and pressure drop characteristic curve. Under the rated oil supply pressure, the total pressure drop (the sum of the pressure drop of the filter shell and the pressure drop of the filter core) should generally be less than 0.2mpa. Oil viscosity test: 60to20Cst low flow turbine :0℃ 60lt/min high flow turbine :0℃400lt/min

 

Judge the quality of hydraulic oil filter element, these knowledge you need to understand

The filter element

 

3. Strength of filter element

 

The rupture - impact resistance test shall be carried out in accordance with iso2941-83 standard. When the filter element is damaged, the sharp drop pressure difference shall be greater than the specified value.

 

4. Flow fatigue characteristics

 

The fatigue test shall be conducted in accordance with ISO3724-90 standard. The filter element must undergo a fatigue test of 100,000 cycles.

 

5. Test the adaptability of hydraulic oil

 

According to iso2943-83 standard, the pressure flow bearing test should be carried out to verify the compatibility of filter material to hydraulic oil.

 

Filtration ratio b ratio refers to the ratio of the number of particles larger than a given size in the fluid before filtration to the number of particles larger than a given size in the fluid after filtration. Nb= number of particles before filtration Na= number of particles after filtration X= particle size.

Generally speaking, the present deformation is likely because the hydraulic oil filter overload things conditions of formation, if say the disorder of the hydraulic oil filter time is 2000-2500 hours, then in the era of the filtering result is good, if cross this time, can affect filtration consequences, formation pressure difference is too high, will be real-time stop replacement
