The function of the oil filter element
In the field of construction machinery, the oil filter element is a key component that ensures the long-term stable operation of the engine. Its core functions can be summarized as follows:
High-efficiency impurity filtration
Intercept metal debris, dust, carbon deposits and gummy contaminants in the engine oil to prevent them from wearing out precision components along with the circulation of the lubricating oil. High-quality filter elements can filter particles as small as 30 microns (about one-third the diameter of a human hair) , while high-performance models can even remove over 99% of impurities larger than 100 microns , significantly reducing abnormal wear and tear of core components such as crankshafts, pistons, and turbochargers.
Extend the life of engine oil and engine
Clean engine oil can slow down the oxidation rate and extend the oil change cycle from the regular 5,000 kilometers to 8,000-10,000 kilometers . At the same time, stabilizing the formation of the oil film can reduce the frictional resistance of moving parts , prevent sludge from blocking the oil passage or scratching the bearing, and directly extend the interval between major engine overhauls .
Ensure the stability of the lubrication system
Extreme working conditions are dealt with through a dual-valve design (such as bypass valves and check valves) : when the filter element is clogged, the bypass valve automatically opens to maintain the oil circuit pressure and prevent cylinder pulling accidents caused by interrupted oil supply
; When the machine stops, the check valve blocks the oil return flow to ensure immediate lubrication when it is restarted.
Optimize energy efficiency and operational performance
A clean lubrication system can reduce frictional energy consumption, decrease power loss and indirectly improve fuel economy . Experiments show that a failed filter element can cause 25% of contaminants to re-contaminate the new engine oil , while regular filter element replacement can maintain stable oil pressure and prevent abnormal increase in engine load .
Special requirements for construction machinery
For the high-dust working conditions and continuous operation characteristics of equipment such as excavators and loaders, the filter element should have:
Enhanced filter material : high-temperature resistant synthetic fiber filter paper (resistant to oil temperatures above 120℃)
Reinforced structure : Anti-vibration design of the metal shell to prevent weld cracking
Large dirt-holding capacity : deep gradient filtration technology extends the maintenance cycle
Maintenance suggestion : Under normal working conditions, replace the filter element every 500 hours or 8,000 kilometers. In dusty construction sites, it should be shortened to 300 hours, and it must be replaced simultaneously with the engine oil to avoid cross-contamination between new and old oil.
