CRE048CD1 Replace Hydraulic Oil Filter

1. What harm can low-quality hydraulic oil filters cause to equipment?

Cleaning is the primary issue when hydraulic oil enters the hydraulic system for operation. Hydraulic pollution is not the dirty phenomenon that people imagine at a glance, but rather the seemingly clean oil that is actually filled with thousands of pollution particles. The filtering effect of low-quality hydraulic oil filter element is poor, and it cannot effectively prevent dirt and other impurities from entering the hydraulic system. If small impurity particles enter the hydraulic system, they will scratch the hydraulic pump (high-precision plunger pumps are commonly used on excavators, wear causes increased clearance, hydraulic pressure cannot rise, and thus work weakly), block the valve, block the oil port, and cause machine failure.

2. How to determine whether hydraulic components are damaged by regularly inspecting and replacing hydraulic oil filter elements?

When replacing the hydraulic oil filter element, please check if there are metal particles or debris at the bottom of the filter element. If there are copper or iron chips, it indicates that the hydraulic pump, hydraulic motor or valve may be damaged or about to be damaged. If there are rubber particles, it indicates that the hydraulic cylinder seal is damaged.

3. The difference between fiberglass products and ordinary hydraulic filter paper

Some of our company's products are made of fiberglass materials with higher filtration accuracy. Compared with ordinary hydraulic filter paper (ordinary wood pulp filter paper, limited by the thickness of its wood pulp fibers, the filtration accuracy is limited, while fiberglass has finer fibers, so it can achieve higher filtration accuracy), fiberglass materials have higher filtration accuracy and stronger resistance to strong pressure.
