​The function of the hydraulic system is to increase the force by altering the pressure. A complete hydraulic system consists of five components: power elements, actuating elements, control elements, auxiliary elements (accessories), and hydraulic oil. Hydraulic systems can be classified into two types: hydraulic transmission systems and hydraulic control systems. Hydraulic transmission systems mainly function to transfer power and motion. Hydraulic control systems aim to make the output of the hydraulic system meet specific performance requirements (especially dynamic performance). The hydraulic system commonly referred to is mainly the hydraulic transmission system.

The influence of air on custom hydraulic systems and the protection measures Under normal circumstances, the proportion of air in hydraulic oil is 6-8%. Due to the decrease in pressure, air can escape from the hydraulic oil. At the same time, the bursting of air bubbles causes cavitation in hydraulic components and generates noise. If this situation occurs frequently and severely, it will make the hydraulic system work unstable, thereby reducing the efficiency of the operation.

Measures to ensure the normal operating temperature of the customized hydraulic system: 1. When the set value of the pressure control valve is too high, the working pressure should be reduced to minimize energy loss. 2. When the hydraulic pump and its connection points leak, causing volume loss and resulting in heat generation, the connections should be tightened and the seals strengthened. 3. When the fuel tank volume is small and the heat dissipation conditions are poor, the fuel tank volume should be appropriately increased. In cases where necessary, a cooler should be installed.

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.
