Customized hydraulic systems can be classified into transmission systems and hydraulic control systems based on their operational characteristics, and into open systems and closed systems according to the circulation mode of the fluid. The design of a hydraulic system generally refers to the design of a hydraulic transmission system. This is because there is no essential difference in structure and working principle between hydraulic transmission systems and hydraulic control systems.

Common Faults of Gear Oil Pumps in Customized Hydraulic Systems and Several Main Methods for Their Elimination The common faults and troubleshooting methods of hydraulic gear oil pumps during the operation of the hydraulic system mainly consist of the following 6 points

In order to extend the service life of hydraulic components and ensure the reliable operation of the hydraulic system, it is a practical and feasible approach to control the contamination level of the hydraulic oil within a certain limit. The pollution control of hydraulic oil mainly focuses on two aspects: one is to prevent contaminants from entering the hydraulic system; the other is to remove the contaminants that have already entered the system.

Let's analyze the causes and solutions of noise generation in the hydraulic system from four aspects. 1.Air intrusion 2. Poor quality of the hydraulic pump or hydraulic motor 3. Improper adjustment of the directional valve 4. The relief valve is unstable.

When designing and laying out pipelines in the hydraulic station system, one should first base it on the hydraulic schematic diagram and comprehensively consider all the connected components, hydraulic systems, three-way joints, and flanges required. The pipeline materials used must have clear initial basis based on the original data. For pipelines with unknown data, they are not allowed to be used.

The disassembly, cleaning and testing of hydraulic components. The hydraulic components are prone to rusting and contamination during transportation or storage. Even new hydraulic components cannot completely eliminate all residual dirt. Uncontaminated hydraulic components should not be disassembled, but they need to undergo functional testing and quality inspection. After the hydraulic system is cleaned, the installation of the hydraulic system is completed. Try to move the system before confirming the pipelines. Perform a cycle of cleaning. The normal operation of the hydraulic system requires extremely strict cleanliness standards. Ensure that the hydraulic pipelines, pipes, valve groups and tanks are clean and free of dirt. Also ensure that the cleanliness of the hydraulic oil meets the requirements.
