Choosing the right hydraulic filter is often not an easy task. Different industries and different components of the hydraulic system have their requirements and affect each other.

So how to choose the appropriate hydraulic filter? As a leading kubota l2250 hydraulic filter exporter, I'll tell you next.

Understand the oil viscosity

When selecting the filter element specification, one often overlooked fact is the oil viscosity. Viscosity has a great influence on the selection of filter element specifications. In the initial selection of filter element specification, the oil viscosity is often ignored.

As a result, the size of the filter element is too large, resulting in unnecessary high operating costs. Failure to understand the importance of oil viscosity may lead to too small filter element specification, too high-pressure drop, premature alarm of pollution transmitter, etc.

On the contrary, it is also possible that the filter element specification is too large, resulting in too high investment cost and operation and replacement cost.

Users need to clearly understand the hydraulic system and evaluate it's rated working temperature range so that the most accurate minimum temperature can be used as the basis for the selection of filter element specifications. Proper selection of the working temperature range can ensure that the filter element will not enter the bypass mode in advance and avoid excessive selection of the filter element.

Familiar with application conditions

The first and most important thing is to understand the performance requirements of the filter. When accurately calculating the filter specification, the performance requirements usually use the filter ratio β Value, the so-called β Value refers to the ratio of the number of particles larger than a certain size in the fluid at the inlet of the filter to the number of particles larger than a certain size in the fluid at the outlet of the filter. therefore β The higher the value, the higher the filtering efficiency of the filter. β The value can also be expressed as a percentage to indicate its efficiency, η= 1-1/ β.

Today's filter designs usually have higher contaminant capacity, longer life, and lower pressure drop.

For example, application conditions requiring high-performance filter elements are usually β If the value exceeds 1000, it means that 1000 particles enter the filter and only 1 particle flows out. In this case, the expression of filtration efficiency is 99.9%.

Generally, regular filter manufacturers have special documents that define filter performance according to the size of the filter element aperture. Therefore, a correct understanding of the application performance requirements can enable you to correctly select the filter element specification and ensure the good operation of the equipment.

Hydraulic system

Once you have established the specific performance requirements for the application conditions, you can correctly evaluate the hydraulic system. According to industry standards, the hydraulic components installed in the hydraulic circuit directly affect the type of hydraulic filter. Such an industry-standard is mainly the ISO cleanliness grade code, which helps us select the appropriate filter type.

The selection of filter needs to comprehensively consider the pollution carrying capacity, pressure drop, and economy of the filter element. If only the gear pump and directional valve are included in the circuit, they are relatively insensitive to pollution. Therefore, the filter with low-performance characteristics can meet its requirements. Knowing what kind of hydraulic components are suitable for what kind of filter and understanding how they affect the performance of the filter can save some unnecessary costs for long-term operation.

Check the flow through the filter

When selecting a filter, it is very important to carefully analyze the flow. It should be noted that the instantaneous flow may exceed the maximum flow of the pump.

The typical working condition is that in an accumulator circuit, the accumulator stores a certain amount of pressure oil. When the accumulator is released, the discharge flow will be superimposed on the pump flow, which greatly exceeds the discharge flow of the pump itself. The high-pressure filter after the accumulator circuit must take this into full consideration.

Underestimating the flow through the filter will increase the differential pressure of the filter element, which will eventually reduce the loop efficiency and increase the operation and maintenance costs.
