Drawing up the schematic diagram of hydraulic system

The formulation of hydraulic system schematic diagram design knowledge is more, the process is complex, need every step carefully and carefully, on the specific details of the method, Xiaobian for everyone summed up a few knowledge.

Hydraulic system diagram is the most important part of the whole hydraulic system design, and its quality will have a decisive impact on the entire hydraulic system. The proposed principle diagram of the hydraulic system of knowledge involved in a wide range, need all the comprehensive use of the use, the general method is: firstly, the basic hydraulic circuit should be selected according to the performance of specific action to choose, then the basic circuit with the necessary connection measures are combined into a complete hydraulic system. The development of hydraulic system diagram, should consider the following issues:

First, the choice of hydraulic circuit

1. first determine the main loop which determines the main performance of the main engine. The main hydraulic system, speed control and speed change is the main circuit.

2. and then consider other auxiliary circuits, such as the system with vertical moving parts to consider the balance loop, the system with multiple actuators should consider sequential action, synchronization and anti-interference circuit, etc..

3. at the same time should also consider saving energy, reduce fever, reduce impact, ensure the accuracy of the movement and other issues.

Two. Synthesis of hydraulic circuit

Hydraulic circuit synthesis is to select all kinds of hydraulic circuit put together, merging, finishing, and then add some necessary components or auxiliary oil circuit, so that it becomes a complete hydraulic transmission system. We must pay attention to the following points when doing this work:

Finally, the integrated hydraulic system should ensure that every action in its working cycle is safe and reliable, without interference;

As much as possible to improve the efficiency of the system to prevent system overheating;

Avoid unnecessary components as much as possible to simplify the system structure;

Standard components are used as much as possible to reduce the design of special parts;

As far as possible, the system is economical and reasonable, easy to maintain and detect.
