The materials used in manufacturing hydraulic oil filters vary based on cost. While metal products are also quite effective, they cannot be used with all types of filters because some hydraulic fluids are not compatible with certain metals. In addition, cellulose or filter paper can also be used as hydraulic oil filter material, but its service life is short and requires frequent replacement.

Although fiberglass filter materials cost more than filter paper, they are often used in depth filters and are more effective and do not need to be replaced as frequently. Be especially careful if you are considering switching to fiberglass from other material types.

And hydraulic oil filter options are not limited to material type and construction, there are also ratings and size issues. If the flow rate of the hydraulic oil filter is too fast, the contaminants will not be effectively removed. If the flow rate is too slow, the hydraulic filter may clog quickly. Therefore, the working pressure must be within the range that the system can withstand. This is particularly important because the components of the hydraulic system are precision mechanisms.

The maintenance of hydraulic systems has very high requirements for industrial oils, such as hydraulic oil, transformer oil, turbine oil, refrigeration oil, lubricating oil, anti-fuel oil, etc. These oils will be mixed with some impurities due to various reasons during use, mainly including mechanical impurities, metal particles and moisture. These impurities will cause accelerated corrosion, increase mechanical wear, reduce work efficiency, worsen oil quality, shorten the service life of equipment, and in serious cases may cause oil circuit blockage and cause production accidents. Therefore, it is important to choose the most appropriate filter element assembly.

In addition, most of the filter element is made of fiberglass filter material, which is then folded into a corrugated shape, and finally a frame and end cap are added.

What needs special reminder is the harm caused by using the filter element for too long: insufficient oil return after blockage leads to an increase in exhaust temperature, shortening the life of the oil and oil separator; insufficient oil return after blockage and insufficient lubrication of the main engine, resulting in serious damage to the main engine life. Shortening; after the filter element is damaged, the unfiltered oil contains a large number of metal particles and impurities entering the main engine, causing loss of the main engine. Therefore, the filter element must be checked frequently and replaced frequently to avoid damage to the main unit.

The quality of hydraulic oil has a great impact on the working performance of the hydraulic system and is the source of many failures. In order to prevent oil pollution, installing a hydraulic oil filter at an appropriate location can intercept contaminants in the oil and keep the oil clean.

The filter replacement cycle of construction machinery will be determined according to the specific use environment, operating load and manufacturer's recommendation. The general rule is to follow the user manual or maintenance guide provided by the equipment manufacturer.

If the construction machinery works in dusty and polluted environment, the filter element may need to be replaced in a shorter period.

Some manufacturers will suggest replacing the filter element according to the working hours, such as every 500 working hours.

Check the filter element regularly for damage and dirt accumulation, so that the replacement time can be determined more accurately.

If your machine starts to show problems such as reduced power or fuel efficiency, this may be a signal that the filter element needs to be replaced.

Some operators choose to carry out machine maintenance and filter element replacement in certain seasons, such as spring and autumn.

However, without specific instructions, a relatively safe general guide is to replace the filter element every year or after each working season.

However, the most important thing is to refer to the recommendations of machinery manufacturers, and always observe and check the condition of the filter element, so as to replace it immediately when there are any signs of performance degradation.

Don't wait for the filter element to completely fail before replacing it, because it may cause irreversible damage to your machine.
