How Does Water Ingression Harm Hydraulic Filter Carts?

How Does Water Ingression Harm Hydraulic Filter Carts?

Water contamination has been an issue in hydraulic filter carts since the day they were employed in industrial equipment.

As a matter of fact, every fluid that has any type of temperature change or water as part of its operational process is susceptible to water and many other types of contamination in its system.

Though hydraulic filter carts play an important role in protecting your equipment from damage, the effects of water ingression, if not dealt with on time, can be very damaging and can lead to expensive repairs.

The best way to avoid water contamination in hydraulic filter carts is by buying them from certified industrial oil filter suppliers.

But the real challenge is to first understand realistically how dry your system should be as a standard and how you can keep the system within that specification. If you are able to master this, then you will never face water ingression issues in your hydraulic filter carts.

In this blog post, we will talk in detail about how water ingression harms hydraulic filter carts.

The Main Problem

The ingression of moisture is unavoidable in any type of machine or equipment that uses lube oil or hydraulic.

However, there are certain types of fluids that make it harder for the water to emulsify or dissolve into the system. But still, it is a big problem that needs to be dealt with on time. Otherwise, it will have the chance to cause ultimate degradation and irreversible damage to your system.

Mitigating water ingression in your system from the start is believed to be significantly easier and results in lower costs as compared to repairing a system that has already been saturated or damaged.

There are many additional challenges posed by the conditions, applications, and environment that make it more difficult for industrialists to deal with water contamination.

If you want to protect your system, you will not only have to limit the effects of the water on the life cycle of your machine but also have to handle different forms of water in the oil, such as dissolved, free, and emulsified states.

There are many filtration systems for different purposes, and there is no one filtration system that fits all applications.

Water contamination can cause premature failure on the moving parts of your equipment, leading to lower productivity and consecutive failures. So by focusing on control, you can protect your equipment from premature failure.

Different Form Of Water

Here are the different forms of water that are usually present in your equipment’s system:

Dissolved Moisture

Dissolved moisture is the lowest form of water contamination in lubricating oil. This type of moisture is derived from the ambient, air, and humidity solely interacting with the lubricating oil over time. Typically, the more additives the oil contains, the more hygroscopic the oil will become.

However, this form of moisture does not greatly affect the viscosity or compressibility of the oil, but if not dealt with on time, it can spread within your system and cause serious damage to it.

Emulsified Moisture

If the equipment is left unchecked, the dissolved moisture will continue to increase within your system until it reaches a saturation point. At that point, any added water will precipitate out as emulsified micro droplets.

These emulsified micro droplets are like the mayonnaise you put in your sandwich. This form of moisture is created by continuous heating, churning, and high pressurization of water into the oil. The saturation point of all lubricants and hydraulic filter carts is different.

Free Moisture

This is the type of moisture that is neither emulsified nor dissolved with the oil sample but remains in a separate and distinct liquid phase. Free moisture is never incorporated into the oil and usually originates from leaks and condensation. It is usually denser than oil. Therefore it settles to the bottom of most engines or just forms a thin film over the metal components of your equipment.

Factors That Influence The Effectiveness of Oil Filtration

Factors That Influence The Effectiveness Of Oil Filtration

We have emphasized the importance of oil filtration for industrial machinery and plants time and again in our informative blogs. Oil contamination is the biggest enemy of proper machine functionality. Surely, the first thing that comes to many people’s minds when they hear the word contamination is dirt and debris. However, even a seemingly harmless droplet of water is considered a contaminant. In fact, water is relatively more dangerous to a machines’ well-being than other contaminants.

As a result, professional oil filtration system suppliers work hard day and night to innovate filtration systems that maximize the effectiveness of decontamination efforts. However, the latter is easier said than done. Freeing the hydraulic oil of the smallest water particles is not as simple as sieving tea leaves from tea. The success of this challenging operation is dependent upon many factors. The latter is what many industrialists fail to comprehend.

From time to time, we meet many manufacturing facility owners who complain of the ineffectiveness of their oil filtration efforts despite investing in high-quality oil filtration systems and filter carts. While quality is one of the factors that impact oil filtration success, it is not the sole determinant of the latter. Thus, industrialists and factory owners must devote equal attention to other factors as well.

In order to help you achieve the best decontamination results, this blog post will discuss the factors that affect the efficiency of oil filtration.

The Performance And Quality Of Oil Filtration Systems And Filter Carts

To be honest, we can’t accurately pinpoint the ineffectiveness of oil filtration to a single variable because it is practically difficult to hold other variables in one position and test a single factor. However, recommendations based on a rough examination are possible. In this regard, the first crucial and most obvious factor that affects oil filtration efficiency is the performance of the oil filtration systems and filter carts themselves.

Undoubtedly, the performance and quality of these devices will primarily depend upon the supplier’s reliability and your decisions. Some industrialists make the mistake of simply considering the price and neglecting quality when purchasing a portable filtration system or filer cart. This decision might seem lucrative in terms of short term savings but proves quite expensive when the need for frequent repairs and unplanned replacements arise.

If you are not cautious enough, these filters may even damage your machinery and reduce their lifespans. This happens when a poor quality filtration system fails to clean the oil, which ultimately finds its way into the machine and hinders its operations.

Therefore, you must always concentrate on the quality rather than the price when purchasing oil filtration systems. Similarly, consider the following when purchasing an oil filter:

  • Capture efficiency
  • Dirt retaining capacity
  • Flow rate
  • Filter media

Temperature, Viscosity, And Flow Rate

Now let us delve deeper into technical filtration terms. The effects of temperature and flow rate on filtration have been tested numerous times. When we speak of filtration, the idea is to force the oil through a barrier to trap contaminants. The amount of oil that passes through a filter at a specific time is known as the flow rate. Now, oil viscosity and temperature are interdependent and directly impact the flow rate.

When the temperature increases, the oil’s viscosity (thickness or resistance to filtration) increases. In turn, less viscous oil has a higher flow rate and can be easily filtered. However, extremely high temperatures result in the severe thinning of oil which causes it to lose its lubricity.

Thus, it is essential to find an optimal balance between temperature, flow rate, and oil viscosity.

Bypass Valve Cracking Pressure

This factor is also commonly known as pressure drop. The latter is the air pressure reduction yielded by a filter. The bypass valve setting of a filter determines this pressure.

Accordingly, filters with a higher pressure drop are more effective than those with a lower valve cracking pressure. Hence, pressure drop has a great impact on oil filtration efficiency.

Soot

Soot diminishes the quality of anti-wear additives in oil. Many experts argue that Standard 40-micron, surface-type, full-flow filters are ineffective in removing soot particles from the oil. When this soot concentration exceeds 3.5%, the whole aim of preventing machine wear through oil filtration is lost.

FAQs:

  • What are the key factors affecting oil filtration effectiveness?
    Several factors impact oil filtration, including the type of filter media, the viscosity of the oil, system pressure, flow rate, and the particle size of contaminants. Selecting the right combination ensures optimal filtration performance.
  • How does oil viscosity impact filtration efficiency?
    High-viscosity oils can reduce the flow rate through the filter, leading to inefficient contaminant removal, while low-viscosity oils flow more easily, enhancing filtration. It’s essential to use filters designed for the specific viscosity of the oil being used.
  • Does system pressure influence filtration performance?
    Yes, system pressure directly affects the flow rate of oil through the filter. High pressure filter systems may require robust filter housings and high-performance media to handle the stress and maintain filtration efficiency.
  • Why is filter media selection critical for effective oil filtration?
    The filter media determines the ability to capture and retain contaminants. Options like cellulose, synthetic, and wire mesh media offer varying levels of filtration efficiency and durability. Choosing the correct media ensures the removal of particles while maintaining proper oil flow.

FAQs:

  • What role does particle size play in oil filtration effectiveness?
    The particle size directly impacts the filter’s efficiency. Filters with finer media can capture smaller contaminants, but they may also restrict oil flow. Selecting a filter that matches the system’s cleanliness requirements and operational needs is critical.
  • How does oil contamination level affect filtration performance?
    High contamination levels can overload the filter, reducing its efficiency and lifespan. Regular monitoring and timely filter replacements help maintain filtration performance and prevent clogging.
  • Does temperature impact oil filtration effectiveness?
    Yes, temperature influences oil viscosity, which affects its flow through the filter. High temperatures can lower viscosity, improving flow but potentially reducing filtration precision. Low temperatures increase viscosity, slowing flow and straining the filter.
  • Why is proper filter placement important for effective oil filtration?
    The location of the filter in the hydraulic or lubrication system determines its effectiveness. For example, suction filters protect the pump, while return line filters clean oil before it re-enters the reservoir. Correct placement ensures maximum contaminant removal and system protection.

How To Detect Oil Contamination In Your Equipment

How To Detect Oil Contamination In Your Equipment

Heavy industrial equipment is used daily to perform a billion tasks and if it is not in good condition then it will adversely affect your machines and your business.

Oil contamination is one of the biggest reasons for industrial equipment failure that can only be avoided by using hydraulic filter carts and oil filters.

Oil filters act as a barrier to stop all the dust debris and other contamination from entering the oil in your machinery.

So if you want to protect your machinery from oil contamination then make sure that you buy your hydraulic filter carts and oil filters from a certified hydraulic filter carts supplier.

Also Read: Different Types Of Oil Filters And Their Function

Oil contamination is a common issue but detecting oil contamination in your equipment is not that simple.

But with the help of regular analysis of your equipment, you can find the potential maintenance issues in your machine and can fix them before they become huge problems.

In this blog post, we will talk in detail about the tests that are done during basic oil analysis and what these tests can tell you about the condition of your machinery.

Fourier Transform Infrared (FTIR) Spectroscopy

FTIR ( Fourier Transform Infrared) spectroscopy is one of the most powerful tools used for oil analysis.

During FTIR each molecule of machine oil absorbs infrared radiation at different wavelengths.

By passing all your oil molecules through infrared radiation you can examine the output and can make a thorough analysis of your machine’s oil makeup.

This will help you find out how much fuel, soot, water and other contaminants are present in your system.

You can use this data to formulate a course of action to minimize the spread of those contaminants in your machine’s system.

The FTIR spectroscopy will also allow you to evaluate the number of helpful antioxidants in your oil system and will help you make sure that your equipment oil does not become oxidized to a harmful level.

Spectrochemical Analysis

Another method that is used to determine the makeup of chemicals in your equipment’s oil is spectrochemical analysis.

The main focus of this test is on the metals, the oil is excited into vapor form. Every metal that is tested creates a different wavelength of light while exiting so you can get an accurate picture of the number of metals present in your equipment’s oil.

During this test, there are two primary types of metal that we are concerned with. The first one is the wear metals that enter your equipment itself as it degrades.

By tracking these metals with the spectrochemical analysis you can find the rate at which multiple parts of your equipment are wearing out.

The second type of metal found in this analysis is the contaminant metals. Tracking these types of metals will help you find out if dust, dirt, coolant or other contaminants are entering your equipment at alarming levels.

Moreover, if your equipment processes materials that contain metals daily then with the help of spectrochemical analysis you will be able to find out how much of those metals are entering into your equipment.

Ferrous Wear Concentration

The spectrochemical test comes with a drawback as it can not detect particles that are large in size.

But don’t worry you can conduct the ferrous wear concentration test to find the exact number of metals present in your equipment’s oil.

Ferrous wear concentration is another useful tool that helps to determine the health of your equipment’s oil at any given time and also tells the wear rate of your machinery.

Final Word

Industrial equipment and machinery go through a lot of oil contamination, so to avoid oil contamination you should use oil filters.

Moreover, the aforementioned tests will help you detect the amount of oil contamination in your equipment and will help you stop contamination before it turns into a catastrophe.
