The leakage problem of the loader's hydraulic system is the result of multiple comprehensive influences. It is not possible to simply, traditionally and passively strengthen the seal, but to systematically eliminate the root cause of the leakage and take effective measures to control it. Proceed from the factors affecting the leakage of the hydraulic system, and take reasonable measures to minimize the leakage of the hydraulic system. Especially in the process of use, the personnel engaged in the management, operation and maintenance of the loader should strengthen their sense of responsibility, based on prevention, and minimize the leakage of the loader's hydraulic system.

Due to the humidity of the working environment and other factors, it may cause external water to enter the hydraulic system. The water will react with the hydraulic oil to form acidic substances and sludge, reducing the lubricating performance of the hydraulic oil, accelerating the wear of the components, and the water will also cause the control valve. The valve stem is rusted, making the control valve difficult to operate and scratching the seals, causing leakage.

Internal control, external control, internal leakage and external leakage of electro-hydraulic directional valve Electro-hydraulics do not separate families. Those who engage in hydraulics may not necessarily be proficient in electrical. Those who engage in electrical must understand hydraulics! Machinery, whether hydraulic or electrical, must master the necessary knowledge, such as machining, turning, milling and grinding machines, tolerance matching, plasma laser line cutting, welding, and so on. But today I want to explain a little knowledge of an electromagnetic directional valve, which is also a problem encountered during a recent project.
