What are Major Components of a Hydraulic Filter Element?

The major components of the hydraulic filter include:

hydraulic filter element structure

hydraulic filter elelment structure

Customized hydraulic filter you need to know the structure

*Center or Inner Tube Support

Most hydraulic applications have a large pressure differential across its elements

Therefore, it has an inner tube support to increase the resistance of the hydraulic filter elements

* End Plate

These are zinc coated or stainless steel sheets in a variety of shapes to hold the tubular filters.

All hydraulic filter elements have two endplates, one at the top and the other at the bottom.

* Tube Filter Filtering Material

This is the main filtering material with a number of pleats to increase the surface area and efficiency of filtration.

You can get a hydraulic filter with different tubular filters such as

* Adhesives

Most hydraulic filter element have epoxy adhesives which bonds the inner cylinder, tubular filter, and end plates together, According to the requirements of some filter elements, SINFT uses special adhesives, and the working environment can adapt to the high temperature of 300 ℃.

* O-Ring

The O-rings act as seals between the filter body and the upper end plates.

You will get an O-ring package according to the hydraulic filter element part number.

* Fin Tube

This is an aluminum alloy tube where the notched wire wraps around and forms a cylinder.

How Does a Hydraulic Oil Filter Element Work?

Hydraulic Oil Filter Element Work?

The SINFT® hydraulic filter elements work based on specific principles including ?

1)Pressure Filtration

The filtration principle relates to filters that are in pressure lines and deliver the ultimate protection for fittings that are downstream.You can use the pressure flow to your advantage by adding filters with ratings of around 2 micrometers or maybe less.In the case of high flow velocities, you may experience a decrease in the effectiveness of the filters. This will be as a result of disturbance to the particles within the filtration trap. Pressure filtration is the most expensive mode of filtration due to high installation and maintenance cost he high cost comes as there is a need to purchase high-quality hydraulic filters to withstand the high pressure.

2)Return Filtration

The principle of the return line for filtration follows the following philosophy: In case the reservoir, fluid, and anything that enters the reservoir have been filtered then it will continue to be clean. Fortunately, you can depend on the return line that makes it possible to force fluid through finer filters. The filters can be as fine as 10 micrometers to trap any form of contaminant in the fluid. In this case, the fluid pressure is not very high and will not interfere with the design of the filter or housing. It will, therefore, make it one of the most economical filtration processes.

3) Return-line Filtration

This is the process of filtering fluids in the hydraulic container in a totally different circuit. It relieves the filters in the main flow of heavy filtration and increases system availability. This will, in turn, lead to a decrease in the cost of operation.

4) Suction Filtration

Suction filtration is the process of separating solids from a solid, liquid mixture with an aim of retaining the solid. It uses the principle of vacuum filtration to separate the solids from the solid-fluid mixture.For instance, crystallization process depends on suction filtration to separate the crystals from the fluid.

What are the Meanings of "Micron" and "Mesh" for Filtration?

micron and mesh

The units for measuring the size of the wire mesh are in terms of the number of mesh per inch.

Implying that, if there are 5 meshes, then within one inch there are 5 gaps.

The size of mesh openings differs according to the wire diameter of the wire mesh even for the same number of mesh.

A micron, on the other hand, is a measurement unit that represents a millionth of a meter.

It is also the ability of a fluid filter to remove the contaminants depending on the size of the particles.

So, the smaller the micron rating of a particular filter, the higher the efficiency of the filter.

What is a Hydraulic Oil Filter Efficiency?

micron and mesh

Filter efficiency is the ability of a hydraulic filter to trap contaminants within the filter element. It is a ratio of particles that a filter element cantrap over the number of particles in the upstream fluid. You can be able to determine the efficiency of the hydraulic filter just by counting the number of downstream particles. You can also tell filter efficiency depending on specific particle size ranges or the total number of particles of all sizes.

What is a hydraulic oil filter beta rating?

SINFT® hydrauclic filter element Beta rating describes the efficiency of a filter in the retention by looking at the particles retained within the filter.describes the efficiency of a filter in the retention by looking at the particles retained within the filter.

Beta rating is often a subscript number for the micron size being considered. Larger beta rating is an indication of a good hydraulic filter with a more efficient particle retention rate. For instance, β4μ means the beta rating for the filter at 4 microns. It also denotes how efficiently 4 micron particles are removed by the hydraulic filter element.

What is the Difference between Absolute and Nominal Ratings?

A measure of the pore size in the filter media is expressed as either 'Nominal' or 'Absolute'.

It also refers to the efficiency of the hydraulic filter element.

Nominal is a standard element of efficiency that depends on surface filtration.

Nominal rating is the percentage of particles of given sizes that hydraulic filters can capture.

For instance, 12 microns at 92% means the filter will remove 92% of particles of 12 microns in size.

Absolute rating, on the other hand, is a high element of efficiency that depends on a higher depth of filtration.

Absolute rating refers to the removal of all particles at a given micron size.

That is, 25-micron absolute means 100% of particles of size 25 microns or greater will be captured.

Absolute and Nominal

Beta rating describes the efficiency of a filter in the retention by looking at the particles retained within the filter.

Larger beta rating is an indication of a good hydraulic filter with a more efficient particle retention rate.

Beta rating is often a subscript number for the micron size being considered.

For instance, β4μ means the beta rating for the filter at 4 microns.

It also denotes how efficiently 4 micron particles are removed by the hydraulic filter element.

What does ISO Code Mean?

You can measure oil cleanliness in terms of ISO1046

This can be equal to or larger than 4, 6, or 14 microns in diameter.

Each ISO code represents a particular range of particle counts.

For example, ISO code 19/17/14 means that:.

*Particles of diameter greater than or equal to 4μ have ISO code 19.

*Diameter that is greater than or equal to 6μ have ISO code 17.

*Diameter that is greater than or equal to 14μ have ISO code 14.
