The working principle of the 5 micron hydraulic oil filter is mainly based on its internal filter structure. The following is the detailed working process:
1. ** Pre-filtering stage **
- ** Coarse filter impurities ** : When the hydraulic oil containing impurities enters the filter, it will first pass through a layer of pre-filter device. This device usually uses a filter or filter layer with a large aperture, which can intercept the large particulate impurities in the hydraulic oil, such as metal shavings, dust, etc. This step is mainly to conduct a preliminary cleaning of the hydraulic oil, remove those impurities with large particle sizes that are easy to cause serious damage to the system, and reduce the burden for subsequent fine filtration.
- ** Protection of fine filter element ** : The pre-filter device also plays a role in protecting the subsequent fine filter element. Without this level of pre-filtration, a large number of large particulate impurities directly contact the fine filter element, which may lead to rapid blockage of the fine filter element, affecting its filtration effect and service life.
2. ** Fine filtering stage **
- ** High Precision intercept ** : The pre-filtered hydraulic oil will enter the fine filtration part of the core, where a 5 micron filter element is used. The filtration precision of the filter element is very high, and it can intercept the tiny particles in the hydraulic oil, including some small metal particles, colloid particles and so on. The material of the filter element is usually a special fiber material or filter paper, which has a complex fiber structure and tiny pores. When the hydraulic oil passes through, the impurity particles greater than 5 micmeters will be intercepted by the fiber and pores of the filter element, while the clean hydraulic oil can continue to flow through the tiny pores of the filter element.
- ** Deep filter mechanism ** : In addition to simple physical interception, some 5 micron filter elements may also use deep filter mechanism. In this mechanism, the internal structure of the filter element has a certain depth and level, and the impurity particles will continue to collide and deposit in the complex channel between fibers during the process of passing through the filter element, so as to further improve the filtration effect. This deep filtration can more effectively remove small impurities in the hydraulic oil and improve the cleanliness of the oil.
3. ** Output ** after purification
- ** Provide clean oil ** : after 5 micron filter element fine filtration of hydraulic oil, its cleanliness has been greatly improved, can meet the strict requirements of hydraulic system for oil cleanliness. These clean hydraulic oils are delivered to the various components of the hydraulic system to provide good lubrication and cooling for the key components such as hydraulic pumps and hydraulic valves to ensure the normal operation of the hydraulic system.
- ** Maintain system Performance ** : A continuous supply of clean hydraulic oil is essential to maintain the performance of the hydraulic system. If the hydraulic oil contains too much impurities, it will lead to the aggravation of hydraulic pump wear, hydraulic valve stuck and other problems, affecting the reliability and efficiency of the system. By continuously filtering impurities, the 5 micron hydraulic oil filter can ensure that the oil in the hydraulic system is always maintained at a high clean level, prolong the service life of the hydraulic system, and reduce the occurrence of faults.
In summary, the 5 micron hydraulic oil filter can effectively remove impurities in the hydraulic oil through three stages of pre-filtration, fine filtration and output after purification, providing clean oil to maintain the performance of the hydraulic system and extend its service life.
