How to Design Hydraulic Circuit?

In the hydraulic transmission system, power is transmitted and controlled through the pressurized liquid in a closed circuit. Hydrostatic drive transmission is a method that uses pressurized liquid as a working medium to transmit, control, and distribute signals and energy. Generally, it should also include the generation and conversion of hydraulic energy. Therefore, the hydrostatic drive system is defined as a device or configuration that generates, transmits, controls, distributes, and converts hydraulic energy and signals through interconnected components and accessories such as piping and hydraulic hose with fitting. Among them, accessories are indispensable in general hydraulic transmission systems.

 

 

Hydraulic Circuit Diagram

According to the definition of automatic transmission hydraulic system, the hydraulic circuit diagram should be defined as the drawing of the hydraulic transmission system or its partial functions represented by prescribed graphic symbols. The part of the hydraulic transmission system can also be called a hydraulic transmission subsystem or subsystem.

 

In addition to the technical requirements specified by the hydraulic power transmission, the hydraulic circuit diagram should also have the following features.

 

1. The drawings of the hydrostatic drive transmission system or its parts are drawn or represented in accordance with the prescribed graphic symbols.

 

2. The liquid in the components, accessories and piping in the hydraulic circuit diagram can be pressurized, and the direction in which the pressure of the pressurized liquid acts on the movable part is clear. Movable parts include actuators. The actions of some movable parts such as pistons and piston rods in hydraulic cylinder can be repeated.

 

3. The hydraulic circuit diagram includes at least one of the functions of generation, transmission, control, distribution or conversion of hydraulic energy and signals.

 

4. The flow direction of the working medium in the unexcited state and the excited state of each element in the hydraulic circuit diagram is clear.

 

5. For the components and accessories or main components such as hydraulic brake hose fitting in the hydraulic circuit diagram, all the connected oil ports have clear symbols indicating the function of the oil ports.

 

The design of the hydraulic system should meet the technical requirements stipulated by the relevant standards. The performance parameters of the various components, accessories and piping in the hydraulic circuit diagram are mostly regulated by the relevant standards. These serve as the technical basis for the analysis and design of hydraulic power transmission systems and circuit diagrams, including design guidelines of superposition valves, cartridge valve hydraulic systems and circuit diagram.

 

The design and selection of hydraulic systems, hydraulic pumping stations and hydraulic components, such as reusable hydraulic hose fittings, piping and oil circuit blocks, include the design and selection of pressure control valves, flow control valves, directional control valves, and hydraulic cylinders.

 

 

Hydraulic systems and circuits are ever-changing and diverse. With the wide application of electric control, electric manipulation, electric modulation and digital components, more typical hydraulic systems and circuits are bound to appear.
