The Relevance Of Hydraulic Filters In The Functionality Of Hydraulic Systems

March 24, 2022

If you own any manufacturing facility, plant, or factory, you probably felt incredibly proud as you have watched the colossal machinery and equipment unwavering carry out their cumbersome duties with utmost devotion and unrivalled energy. However, things often turn bitter when your loyal machinery begins to twitch or tremble slightly. The latter is obviously not a good sign for any industrialists. It signifies the upcoming losses in the form of machinery downtime and the resulting losses. We will read about the relevancy of hydraulic filters.

Wise men are often heard saying that instead of curing an illness from the surface, delve deeper into its core and uproot the problem to eradicate it permanently. Hence, when your machinery gives up and production halts, instead of simply fixing the issue at hand, find out exactly what led to the problem.

As top-rated suppliers of premium quality oil filtration systems and hydraulic filter carts, we believe the problem most likely lies in your machine’s hydraulic system. Most of the time, a malfunctioning hydraulic system is the main culprit behind the profits you forego as a result of a machine’s downtime. Hence, the first step is to understand why a hydraulic system stops working.

Although the subject may sound a bit technical, we shall use this blog to systematically explain a hydraulic system and the relevance of hydraulic filters in their proper functioning straightforwardly.

What Is A Hydraulic System?

In simple terms, a hydraulic system is a complex integration of various components such as hoses, pipes, valves, etc., to pressurize non-compressible fuel to generate energy. We wouldn’t be wrong to say that it drives fuel-powered machinery (also known as hydraulic machinery) to perform the required task repetitively. In physics and other disciplines, you may hear that hydraulic systems work as per Pascal’s Law.

These machines are used in all industries that demand high power density due to their relatively low costs and longer lifespan. Hence, hydraulic systems are primarily found in heavy equipment used in various heavy industries like construction, manufacturing, etc. From digging to drilling, lifting heavy loads, and even turning a shaft, hydraulic machinery performs a vast range of functions.

Through proper care and maintenance, you can even increase the lifespan of the said machinery. Evidently, such colossal machinery and equipment may look unshakably and hard to stop. However, a few particles of sediments or even water droplets may halt them. Research has revealed that fuel contamination accounts for up to 75% of hydraulic system failure.

To this end, many people believe that selecting the most expensive fuel is sufficient to overcome this issue. However, it is wrong to simply assume that expensive or the right type of fuel lacks contamination.

How Contaminants Enter The Hydraulic System

Contamination in any form is a hydraulic system’s biggest enemy. It can enter the system in numerous ways, including:

Contaminants That Come With New Machinery

These are contaminants that are unintentionally left in the hydraulic system during the manufacturing and assembling process. They could be anything from dust to metallic particles.

Impure Fluids

The oil that finds its way into the system may also contain dust, debris or even water droplets. These seemingly harmless elements are actually the major reason behind many machine breakdowns. Although the oil may be clean after it is manufactured, it may become contaminated during transportation, storage, or usage stages.

Repair And Maintenance

Regular machine inspection, repair, and maintenance processes may also introduce external contaminants into the system.

Contamination Resulting Internally

Like any other mechanical device, a hydraulic system is also susceptible to wear and tear. Hence, the internal deterioration of the components may cause small particles of the metal to enter the system and disrupt its functionality.

How To Keep The Hydraulic System Contamination-Free

• Use only the best quality of oil and ensure it is as least decontaminated as possible.
• Abide by the exact specifications when adding fluid/oil into the system.
• Regularly perform fluid contamination tests to ensure that it is clean.
• Make use of a suitable hydraulic filter cart to filter the oil regularly.
• While fixing the system, make sure the hydraulic hoses are correctly connected.
• Always try to fix leaks as soon as feasible.
• Ensure that your team uses standard Beta 1000 elements in all filter enclosures and replace them as needed.
• Attach a premium quality breather to the reservoir.
• The area surrounding the reservoir must be kept tidy.

Evidently, the use of oil filters and proper maintenance are an obligation for the proper functioning of a hydraulic system.

FAQs:

1. Why are hydraulic filters essential in a hydraulic system?
Hydraulic filters play a critical role in maintaining system efficiency and longevity. They remove contaminants like dirt, metal particles, and sludge from hydraulic fluid, which can otherwise cause wear, corrosion, and potential failure of system components. Clean fluid ensures smooth operation and extends the lifespan of the equipment.

2. What types of contaminants do hydraulic filters remove?
Hydraulic filters are designed to eliminate various contaminants, including solid particles (dust, dirt, metal shavings), water, and sludge. These impurities can accumulate over time, leading to reduced system performance, increased wear, and potential system breakdown.

3. How often should hydraulic filters be replaced?
The replacement interval for hydraulic filters depends on factors like system usage, operating environment, and the manufacturer’s recommendations. However, regular inspection and maintenance are crucial. Replacing filters on time helps prevent clogs and ensures optimal fluid cleanliness, protecting the hydraulic system.

4. What are the consequences of neglecting hydraulic filter maintenance?
Neglecting hydraulic filter maintenance can result in contaminated fluid circulating through the system, causing damage to critical components such as pumps, valves, and cylinders. This can lead to reduced efficiency, unplanned downtime, and costly repairs or replacements. Proper filter maintenance is essential to avoid these issues.
