The hydraulic system schematic diagram is a difficult point for many people to start the hydraulic industry. It takes a lot of work to fully understand a schematic diagram.

1. Study the relevant books that you can find within your ability. For many people who study hydraulic technology courses, the content of the books they use is relatively old and classic, so they need to be supplemented with materials.

2. Understand electro-hydraulic control technology. Many people have a better understanding of hydraulic transmission, but electro-hydraulic control technology is not. The current hydraulic system has requirements on these two aspects, such as proportional valve, high-speed switching valve, servo valve and other hydraulic control contents, all need to be deeply understood.

3. Understand the theoretical knowledge of construction machinery, and now the book of construction machinery hydraulic technology. Most of the content comes from samples and instructions for use, and the necessary analysis is lacking, so it takes extra time to understand. Furthermore, it is necessary to overcome the differences between hydraulic technology and construction machinery hydraulic terms. For example, the one-way steady flow valve is actually a constant flow valve.

1. With the development of hydraulic technology component technology, the application field continues to expand. Now many hydraulic component graphic symbols cannot keep up with the development. Therefore, in daily work and study, you must learn to collect and summarize.

2. The new and unconventional symbols of manufacturers are constantly appearing. Nowadays, the "new symbols" on the oil circuit diagram of many hydraulic systems are troublesome even for hydraulic veterans. At this time, it is necessary to analyze its functions as a whole, find unconventional laws from the samples, and help complete the work.

Only by understanding the principle of the main engine can we analyze and understand the schematic diagram of the hydraulic system in a more organized manner. If the system is more complex, it can be analyzed according to the following methods.

1. First, split the oil circuit diagram into three parts: actuator, oil source, and control, and understand the work and requirements of the actuator.

2. To figure out the oil source, there are also three major blocks - single pump or multi-pump, quantitative or variable, single supply or confluence. Start with the actuator, find the oil source pump, and clarify the corresponding relationship.

3. Analyze the control part of the pump and actuator chain.

If you do anything without practical experience, it will be nothing on paper. If you want to understand the schematic diagram of the hydraulic system, it is most obvious to go to the field to inspect the system. Learning summary methods in one practice is more useful than reading hundreds of books.
