For these reasons, here is a look at these parts.

· Auto- pull Element removal tabs

These tabs exist to assist in safe extraction of the filter element when you open the filter housing.

This is crucial when you are replacing the filter element.

· O- ring seal

The o- ring seal is an outer round seal that is normally dark in color and of rubber material.

The function of this component is to restrain the contaminants from bypassing the filter element under normal operation.

· Center steel tube

This is the innermost component of your filter elements whose composition usually is metal.

It functions as a protective layer by offering the necessary support that the inner parts of the filter elements require.

This prevents the inner parts from collapsing.

· Perforated protective cage

At the top and bottom end of the filter element, you will find around protective cage.

The function of this cage is to offer stability to the supporting tube as well as the inner components of the filter element.

· Proprietary Cushion layer

The function of this component is to offer support for the element and protection when you are handling it during replacement and cleaning.

· Mesh layers

The mesh layer offers a flow channel for the oil which ensures there is uniform flow.

The mesh layer goes a long way in extending the life of the filter element thereby reducing the operating cost.

· Pleats

The function of these pleats is to hold the contaminants from your oil which ensures that the oil is clean.

The number of pleats depends on the thickness of your oil.

How Filter for Wind Turbines Works

With the knowledge of the components of a filter element, you can now go ahead and understand how this device works.

Even though it may appear complicated, the truth is that the working principle of this device is pretty simple.

Here is how it works.

The oil enters the filter through the bottom inlet flowing from the inside to the outside and into the filter element.

In the filter element, the creases hold back the contaminants available on the oil as it flows.

As it flows outside the filter element, the contaminants flow to the bottom of the filter element.

The process continues until when clogging occurs on the creases of the filter element.

Clogging causes a drop in pressure of the oil which in turn affects the quality of filtration of your oil.

When this happens, you need to either clean up your filter element or with time; you will have to replace it with a new one.

Factors to Consider in Choosing Wind Turbine Filter Elements

Let’s agree that you cannot just walk int the market and select any filter element for your wind turbine.

Whichever filter element that you choose, you need to ensure that it perfectly fits your wind turbine and that it functions efficiently.

So, what are these factors that you need to consider when selecting a filter element for your wind turbine?

Turbine oil filter system

Here are the answers to this question.

1) Degree of filtration

We must agree that in what you will find in the market are different filter elements with varying capabilities of filtration.

The choice of which filter element will depend on the level of filtration that you want for your turbine.

The degree of filtration of your turbine filter depends on the optimum working level of your turbine.

This means that if you want finer filtration, you will have to pick a filter element that has finer mesh.

A proper filter element for your turbine is one whose degree of filtration enables your turbine to work efficiently and effectively.

2) Maintain low-pressure drop

One thing that you need to avoid is allowing the pressure of the oil to drop.

No matter what, the pressure needs to be constant to ensure that the turbine, as well as the gear, works efficiently.

One of the ways that you can maintain the pressure of the oil is by selecting a turbine filter element that has the right pressure ratings.

3) Wind turbine filter element construction

What is the design of the filter element?

This is a key consideration when selecting a filter element for your turbine.

The design of your filter element is generally regarding the height, the length, and the width.

These dimensions need to fit the space on your filter.

Therefore, the design of the filter element is a consideration for selecting a filter element for your filter.

4) Efficiency ISO 16889

Not all the wind turbine filter elements will offer the desired effect that you need for your turbine.

There are some brands which are not that effective in ensuring that your turbine works efficiently.

As such, efficiency needs to be a factor of consideration when selecting a wind turbine filter element for your turbine.

As a basic rule, ensure that the effectiveness of your turbine filter element is ISO 16889: Beta >1000 certified.

Also, you need to ensure that its efficiency is at least 99.9% of the total flow of the oil in the turbine.

5) Quality standards

There are many turbine filter elements in the market. However, not all these filter elements meet international standards.

You, therefore, need to be very careful when selecting a filter element for your turbine.

Always ensure that the filter element that you select for your turbine filter meets the relevant quality standards.

This will ensure that the filter element that you choose offers you durable and quality service.

6) Fluid compatibility

Another critical element of your consideration when selecting a wind turbine filter element is checking on the compatibility of your fluid.

As you may know, filters and by extension filter elements have a wide range of applications.

As such, you have different types of filter elements such as an air filter element, the oil filter element, and water filter element.

You, therefore, need to pick a filter element that will be compatible with the filter of your turbine.

Also, ensure that the oil of your turbine is compatible with your filter element.

This is concerning the viscosity of the fluid.

7) Working temperature range

Your choice of filter element needs to fit the temperature range of your turbine.

The gear and the turbine frequently generate heat during operation which varies depending on the size of the turbine.

The composition of the filter element usually are materials which can easily get damaged when exposed to a temperature above a given limit.

You, therefore, need to ensure that you select a filter element that can work properly on your turbine filter.

Typically, there is a label indicating the range of the temperature that a given filter element can handle.

8) Working pressure range

The flow of the oil in your turbine filter is normally at a given pressure which ensures that there is proper filtration of your oil.

This pressure can lead to tearing of your filter element due to the force.

It is, therefore, necessary that you select a filter element that can withstand the pressure of the oil during filtration.

Different filter elements have different pressure range which you can check on the filter element.

To ensure compatibility, the pressure range of the filter and that of the filter element needs to be the same.

Wind Turbine Filter Element Replacement

With time, your filter element attracts all forms of impurities present in your oil clogging it up.

Even if you clean it up, the efficiency of its working keeps deteriorating.

At some point, impurities will find their way into crucial parts of your engine and by extension your turbine.

If this persists, the productivity of your engine is much affected.

To prevent this, you need to replace the filter element of your turbine filter once it gets clogged up.

Several signs can indicate that you need to replace the turbine filter element.

They include the following:

· Cracking of the end caps

The ends of your filter are of plastic which means they are vulnerable to any chemical reaction that may occur within the filter.

When the reaction takes place, these ends start cracking leading to your filter element becoming ineffective.

When you start noticing the cracks, it is a higher time you replace your filter element

· The creases flatten out

Another indication that its time that you replace the filter element of your turbine is when the creases flatten out.

The primary cause of this flattening is clogging of the filter element which makes filtration ineffective.

To maximize filtration, always ensure that you replace the filter element once you notice flattening of the creases.

· The reduced oil flow rate

When the flow rate of your oil slows down, then it is time that you replace your filter element.

Clogging of the filter element is the leading cause for this which prevents the oil from flowing.
