(6) Effect of surface hydrophilicity on sealing property The hydrophilicity of the surface affects the amount of leakage due to the characteristics of the capillary. When there is a thin film of oil on the sealing surface, it is necessary to increase the pressure of the water passing through the gap. Due to the good hydrophilicity of the metal surface, kerosene can easily penetrate the gap between...

In industrial valve systems, strainers are essential components for ensuring smooth fluid flow and protecting downstream equipment. However, when an oil strainer becomes clogged, it can lead to a series of issues, significantly impacting the system's stability and safety.   Common Causes of Oil Strainer Blockage (1) Excessive Impurities The working medium contains a large amount of particulat...

In hydraulic systems, lubrication systems, and even automotive engines, "clean oil" is the cornerstone of reliable operation. To filter out contaminants from oil, two common devices are used: oil filters and strainers. While often grouped under the umbrella term "filters" in Chinese, they serve distinct roles in engineering applications. This article dissects their differences across multiple dime...
