The Complete Guide to Hydraulic Oil Filters

Hydraulic oil filters are essential in protecting components and systems from wear, dirt, and other damages. In this article, we look into the basics of hydraulic oil filters and explore its pros and cons. From types of filters to installation methods – get ready to know everything you need to know about hydraulic oil filters!

Introduction of hydraulic oil filters

As the name suggests, hydraulic oil filters are used in a variety of hydraulic systems to remove contaminants from the oil. These filters can be either inline or canister type, and they work by using a filter element to trap contaminants as the oil passes through.

Hydraulic filters need to be able to remove both particulate matter and water from the oil, as both can cause problems in hydraulic systems. The size of the particles that need to be removed will vary depending on the application, but generally speaking, most hydraulic oil filters are designed to remove particles down to around 5 microns in size.

Water is particularly problematic in hydraulic systems, as it can cause corrosion and other damage. It can also cause problems with the performance of the system, as water will not compress like air or oil. For this reason, it is important that any water present in the hydraulic system is removed before it has a chance to cause damage.

There are a few different types of hydraulic filters available on the market, each with its own advantages and disadvantages. Inline filters are typically less expensive than canister type filters, but they can be more difficult to install and maintain. Hydraulic canister filter or canister type filters tend to be more expensive up front, but they are often easier to install and maintain over time.

Types of Hydraulic Oil Filters

There are two types of hydraulic oil filters: return line and suction. Return line filters are located between the pump and reservoir, and suction filters are located between the reservoir and pump.

Return line filters remove particulates from the hydraulic fluid as it returns to the reservoir. Suction filters remove particulates from the hydraulic fluid before it enters the pump.

Benefits

Hydraulic oil filters improve the performance of your hydraulic system by removing contaminants from the hydraulic fluid. Contaminants can cause wear on components, reduced efficiency, and premature failure.

There are a few factors to consider when deciding when and how often to change the hydraulic oil filter, such as the type of system, operating conditions, and types of oil filter.

Type of System: The first factor to consider is the type of hydraulic system. If the system is used for mobile equipment, such as construction equipment or agricultural machinery, it is subject to more contamination than a stationary system. This is due to the fact that mobile equipment operates in more extreme environments and often picks up dirt and debris while in use. For this reason, it is recommended to change the hydraulic oil filter more frequently in mobile systems.

Operating Conditions: The second factor to consider is the operating conditions of the system. If the system is used in a dirty or dusty environment, it will require more frequent filter changes. This is because a dirty environment will cause the filter to clog more quickly. Conversely, if the system is used in a clean environment, such as a laboratory or factory setting, it will not need to be changed as frequently.

Type of Filter: The third factor to consider is the type of filter being used. There are two main types of filters – disposable and reusable. Disposable filters must be replaced when they reach their maximum capacity and can no longer effectively remove contaminants

What Are The Risks Associated With Not Changing the Oil Filter Regularly?

Engine oil will become too dirty, leading to increased wear and tear on engine components

Dirty oil can also cause clogged oil filters, resulting in decreased engine performance and shortened engine life.

In extreme cases, dirty oil can cause complete engine failure.

Changing your oil filter regularly is one of the easiest and most important ways to extend the life of your engine and protect your investment.

How Much Do Different Types of Hydraulic Oil Filters Cost?

Different types of hydraulic oil filters can cost anywhere from $5 to $50, depending on the size and capacity of the filter. For example, a small, inline filter for a home workshop might cost around $5, while a large, heavy-duty filter for an industrial application could cost $50 or more. The type of filter you need will depend on the specific hydraulic system you’re using.

In general, though, hydraulic oil filter can be divided into two main categories: full-flow filters and bypass filters. Full-flow filters are designed to filter all of the hydraulic fluid passing through the system, while bypass filters only filter a portion of the fluid. Bypass filters are typically used in systems where there is a high demand for Hydraulic power, such as in construction or agricultural machinery.

The cost of replacing your hydraulic oil filter will also depend on how often it needs to be replaced. In most cases, it’s recommended that you replace your filter every 6 months to 1 year. However, if your system is subject to heavy use or contamination, you may need to replace it more frequently.

Common Oil Filter Failures And Their Solutions

Common Oil Filter Failures And Their Solutions

Oil filters are responsible for supplying clean and filtered oil to your machine’s important components. Different types of oil filters perform different functions. They make sure that quality lubricants are being supplied to the essential parts of the machine so that it will work properly.

However, problems can arise with the filtration parts. Any problem with the oil filtration system of the machine can lead to bigger problems and lead to complete machine failure.

Therefore, knowing them in advance or conducting a regular machine analysis is necessary to avoid bigger filtration problems. Each filter also has a distinctive failure and detection method.

Therefore, you must be proactive at detecting such problems on time and take the right measures. Also, choose a company that offers quality filters and related products. Harvard Filtration offers filtration systems and filter carts with the most trusted and dependable portable hydraulic filtration systems.

This blog post highlights some common Oil Filter Failures and their solutions.

Fatigued Cracking

Fatigued cracking occurs when the filtration system is overworked. The operational stresses such as high pressure and violent cycle shifts can affect the filter’s weave and warp it.

This damage to the filter can make the oil flow bypass the filter and allow the contaminants to circumvent capture.

This process results in an increased particle count in the oil. This contamination can lead to the poor function of the machines and affect their longevity. Therefore, regular analysis and maintenance of the machines and their parts are necessary to ensure that everything is working as it should.

Plugging Or Blocking

Plugging is another common issue often dealt with when talking about filter failure. Filters can degrade over time when left to constantly work without an oil change or the proper maintenance. The risk of filter plugging further increases if the filter has worked for a prolonged period of time without any change or analysis. Some failure products, such as carbon sludge and varnish, appear. Contaminated filters can affect the oil flow and restrict the filtration process.

The process of oil analysis might not detect the plug failure. An increased pressure change across the filter is detected, which is a tell-tale sign of plugging. Because plugging is caused by the consecutive work of a filter and oil, changing the oil and filter can reduce this problem. Therefore, is it vital that you get your hands on some quality machine filters and related parts here.

Channeling

Channeling is a process where the filter weave or screen is bombarded with abrasive particles at high speeds. These particles are forced through the filter’s pores and become enlarged. They erode the filter material or lodge in the filter’s pores. It then forces itself through the filter and passes through the pores, thus expanding them.

Channeling can be detected by the oil analysis process, where you can count the large particles through the particle count test.

Media Migration

Media migration failure is somewhat similar to fatigue cracking, but in this case, the high-pressure transient ruptures destroy the filter. In the case of fatigue cracking, oil bypasses a warped filter media, whereas, in the case of media migration, the oil flows through the damaged filter.

The damaged filter fails to collect the contaminants and other particles. Moreover, as oil flows through the ruptured media, it collects the particles, increasing the contamination.

Media migration failure can be detected using regular oil analysis processes. Moreover, replacing oil and filters can also minimize media migration.

Final Thoughts

Oil filter failures can occur due to numerous reasons. The only thing that matters is regular oil analysis and maintenance. Checking the condition of your oil and filters and changing them on time will reduce such failures and keep your machines in good working condition.
