Gold end cover excavator oil filter
Introduction to Gold End Cover Excavator Oil Filter
The golden end cap excavator oil filter is a core filtering component designed specifically for construction machinery. Its main body is made of metal end caps, usually galvanized steel or stainless steel, with high strength and corrosion resistance, and can withstand high temperature and high pressure environments. The interior of the filter element adopts multi-layer composite filter paper, which increases the filtering area through precision folding technology, and is reinforced with a metal mesh skeleton to enhance structural stability. The two ends of the filter are tightly connected to the engine lubrication system through rubber sealing rings, ensuring no leakage during the filtration process. Its design integrates the principles of full flow and split flow filtration. The main filter element is connected in series between the oil pump and the main oil passage, which can intercept more than 99% of particulate impurities. The dual protection mechanism of the bypass valve and overflow valve can ensure oil circulation under extreme working conditions and avoid engine damage due to lack of oil.
Characteristics of Gold End Cover Excavator Oil Filter
The core advantage of this filter lies in its efficient filtration and adaptability to extreme environments. The filter paper is treated with resin impregnation, which can maintain stable filtration performance in the temperature range of -40 ℃ to 150 ℃. Even if the oil viscosity changes dramatically, it can still maintain a flow rate of 10-15 liters per minute. The metal end cap undergoes anodizing treatment, forming a dense oxide layer on the surface, effectively resisting salt spray and oil corrosion, and extending its service life to over 5000 hours. The internally equipped reflux suppression valve can lock the oil in the filter element after the engine is turned off, instantly establish oil pressure during cold start, and reduce dry friction damage; The overflow valve can automatically open when the filter element is clogged, allowing unfiltered oil to circulate briefly and provide emergency lubrication for the engine. These designs achieve a filtration efficiency of 98%, far exceeding industry standards.
Golden end cover excavator oil filter usage range
The golden end cap oil filter is widely used in the engine lubrication system of various construction machinery, especially suitable for heavy equipment such as excavators, loaders, bulldozers, etc. In mining scenarios, its corrosion-resistant end caps can resist the erosion of ore dust and humid environments; At construction sites, high flow design can meet the high load operation requirements of engines, maintaining stable performance even after 20 hours of continuous operation. In addition, the filter is also suitable for scenarios that require long-term lubrication protection, such as diesel generator sets and marine power systems. Some high-end models have passed ISO 4548 international standard certification, with a filtration accuracy of up to 5 microns, which can intercept small impurities such as ferromagnetic particles, significantly reduce engine wear rates, extend overhaul cycles to over 3000 hours, and become key consumables for maintenance and upkeep of construction machinery.
