In hydraulic systems, the “channels” are often overlooked — yet hydraulic hoses are in fact the critical link through which hydraulic fluid is pumped, passes through valves, drives actuators, and then returns to the reservoir. Like blood vessels, they carry hydraulic medium, endure pressure shocks a

In hydraulic system design and maintenance, there are two groups of components that frequently appear, yet are easy to confuse: first, the “check valve” versus the “pilot-operated check valve”; and second, the “external-gear pump” versus the “internal-gear pump.” Understanding their structures, oper

In many hydraulic systems, one of the most frustrating failures is when a hydraulic motor stops turning.It’s easy to assume that the motor itself is broken—but in most cases, the problem lies elsewhere in the hydraulic system.This article will help you fully understand why an old hydraulic motor fai

In hydraulic systems, the hose-to-equipment interface faces high pressure, temperature swings, vibration, and corrosion. The connection must stay leak-free and mechanically strong. That’s why the crimp fitting—a permanent, machine-crimped connector—plays a critical role in building reliable hose ass

Hydraulic cylinders are a vital power component in countless machines. They convert the energy of pressurized hydraulic fluid into controlled linear motion.If you operate equipment that relies on hydraulics, understanding the structure of the hydraulic cylinder is essential for correct maintenance a

In our previous article, we discussed the hydraulic pump system and its overall working principle. To briefly review, a hydraulic system is a power transmission technology that uses fluid as the medium to transfer energy. It converts the mechanical energy from an electric motor into fluid energy, wh

The viscosity of hydraulic oil is the lifeblood of any hydraulic system. It’s not only about being “thick or thin”; it determines how oil flows and forms a lubricating film under different temperatures and pressures, thereby influencing system efficiency, reliability, and service life.1) What Is Hyd

Here is a polished English version of the article:Hydraulic systems are everywhere—from excavators and lifting platforms to engineering machinery. But when a “hydraulic leak” occurs—that is, hydraulic fluid ending up where it shouldn’t—the consequences can be far more serious than just a puddle on t
