Hydraulic System Design

Hydraulic system design
The design steps and design requirements of the hydraulic system The hydraulic transmission system is an integral part of the hydraulic machinery, and the design of the hydraulic transmission system should be carried out at the same time as the overall design of the main engine. When starting the design, we must start from the actual situation, organically combine various transmission forms, give full play to the advantages of hydraulic transmission, and strive to design a hydraulic transmission system with simple structure, reliable work, low cost, high efficiency, simple operation and convenient maintenance.


1) Determine the form of hydraulic actuator;

2) Analyze working conditions and determine the main parameters of the system;

3) Develop a basic plan and draw up a schematic diagram of the hydraulic system;

4) Select hydraulic components;

5) Performance checking calculation of hydraulic system;

6) Draw work diagrams and prepare technical documents.


1) Overview of the main engine: use, performance, process flow, operating environment, overall layout of the hydraulic power unit, etc.;

2) What are the actions to be completed by the hydraulic system, the sequence of actions and the interlocking relationship with each other;

3) Movement form and movement speed of hydraulic drive mechanism;

4) The size and nature of the load of each action mechanism;

5) Performance requirements for speed range, smoothness of motion, conversion accuracy, etc.;

6) Requirements for automation procedures and operation control methods;

7) Requirements for dust-proof, explosion-proof, cold-proof, noise, safety and reliability;

8) Requirements for efficiency and cost.
