The cleaning method and steps of the hydraulic oil filter element, how to replace the filter element

Hydraulic oil filters can remove contaminants from hydraulic systems that cause 80% of system failures, reducing the cost of running hydraulic systems by preventing system downtime and frequent wear of parts due to contamination, protecting hydraulic system components such as fittings, hoses, valves, pumps, etc.) from contamination that could otherwise cause damage. Depending on the micron rating, hydraulic filters can remove very small (barely visible) contaminants. Reduce the frequency of system maintenance and component replacement, ensuring hydraulic systems are safe and clean.

Are hydraulic oil filter parts cleanable?

Yes, the hydraulic components are washable. You can only clean screen elements and fiberglass elements. The paper material is not cleanable and you will replace it as soon as it becomes clogged.

How do I clean cleanable components? How many times can you clean?

Cleans cleanable elements, including wire mesh and metal fiber elements, for up to 5 cleanings.

How to clean the filter screen

You can use different cleaning methods to clean the screen by following the steps below.

Step 1: Soak the Wire Mesh Hydraulic Filter

First, you need to remove the wire mesh element from the hydraulic press. The most common way to clean screen elements is to wash in a clean solvent. In addition to a clean solvent, you can also use a hot soapy ammonia solution. Then you need to deepen and soak the hydraulic filter in a solvent or solution to soften the contamination.

Step 2: Remove Contaminants

Use a soft-bristle brush to remove contaminants that may be adhering to the screen elements. Brush lightly for a while and make sure nothing is left on the silkscreen elements. Do not use wire brushes or abrasive materials of any kind, they will damage the mesh elements.

Step 3: Rinse the Elements

After that, you will rinse the screen elements with clean water. You can soak it in clean water or use a hose to splash clean water over the filter element.

Step 4: Dry the Components

You can ventilate the wire mesh elements to allow them to dry. You can also blow dry the mesh elements with clean air to remove water. Alternatively, you can use the more expensive ultrasonic cleaning method. In this case, you will need to place the wire mesh filter element in the ultrasound device for a while. After that, you will remove the silkscreen element and replace it for reuse. This method is also applicable to metal fiber elements. Although the cost is a bit high, it is more convenient and saves you a lot of time and effort.

What is the service life of the hydraulic filter element?

The service life of a hydraulic filter element depends on different variables. In order to calculate the length of service life, some factors you need to know include: the dirt content or cleanliness of the hydraulic filter element, the dirt intrusion rate of the hydraulic system, the dust holding capacity of the filter element. The higher the quality of the hydraulic filter element, the higher the dirt adsorption capacity. This means it will hold more dirt for a longer period of time and last longer. You can clean or replace the filter element whenever it becomes clogged. On average, you should be able to replace the filter element after 6 months for better efficiency.

Should I change the hydraulic filter regularly?

If you are changing the filter element on schedule, you may have changed the hydraulic filter too late or too early. A lot of money will be wasted if hydraulic filter elements are replaced early. That means you’ll be replacing them before all their dust-holding capacity is used up. In case you change them too late, especially after a filter bypass, you run the risk of increasing particles in the oil. More particles in the system can be extremely dangerous to machine components. It will silently reduce the life of every component in the hydraulic system. Repairs and replacements will cost you more time in the long run. Therefore, when all the dirt holding capacity of the filter is used up, but before the bypass valve opens, the filter should be replaced. You will need a mechanism to monitor the pressure drop or restriction of flow through the filter element. When the hydraulic filter element reaches this point, the mechanism will alert you. However, the best solution is to continuously monitor the pressure drop across the filter.

How to replace the hydraulic filter?

When the filter reaches a set pressure drop or becomes clogged with contamination, you need to replace the hydraulic filter element. To ensure continuous and optimal filtration performance, you need to replace the hydraulic filter by following these steps:

Step 1: Take the hydraulic press offline

First, you must ensure that the hydraulic system is offline. You will reduce the chance of injury and create an adequate work environment. Allow the system to cool down for a while before proceeding with the replacement procedure.

Step 2: Drain and drain the hydraulic filter housing

At this stage, you will remove the hydraulic filter housing to expose the hydraulic filter. After that, you will drain all hydraulic oil from the system to avoid unnecessary spillage.

Step 3: Replace the hydraulic filter

Remove the hydraulic oil filter cap and remove the used hydraulic filter element. Install the new hydraulic filter element in place. Check and install cover gasket to reseal hydraulic system. Bring the hydraulic system back online and continue the filtration process.

The above are the cleaning and cleaning methods and steps of the hydraulic oil filter element. During the daily use of the filter element, it should be cleaned regularly to prolong the service life of the hydraulic filter element. Of course, for the hydraulic oil filter element that has exceeded its service life, the hydraulic oil filter element should be replaced in time for the normal use of the equipment. The steps and methods for replacing the filter element are described above, and I hope it can help you.
