General steps for designing a hydraulic system

The design steps of the hydraulic system are in strict order, and each step is often interspersed with each other.

The general step is to clarify the design requirements. It is necessary to clarify the purpose of the hydraulic system and design the hydraulic system according to the actual use needs of the customer.

Clarify the design requirements;Determine the executive components; draw the system condition diagram; determine the working pressure; determine the executive component scheme; draft the hydraulic schematic diagram; calculate the main parameters; select the hydraulic pump; select the hydraulic components; select the motor; calculate the hydraulic auxiliary parts; verify the system performance; draw a work diagram; prepare technical documents.

Clarify the design requirements and analyze the working conditions; formulate the schematic diagram of the hydraulic system; calculate and select hydraulic components; draw work diagrams and prepare technical documents. In the actual design work, the above steps are not fixed. For simple systems, some steps are often omitted or merged.

Design content Design calculation (4 days) Calculate the working conditions according to the given parameters, determine the main parameters of the system, formulate the schematic diagram of the hydraulic system to select hydraulic components, and analyze and verify the main performance of the hydraulic system.Draw drawings (3 days) a) Draw a schematic diagram of the hydraulic system; b) Draw a hydraulic cylinder assembly diagram.

General design work can be carried out by referring to the following steps. 1) According to the design basis and the action requirements of the load mechanism, the design scheme is preliminarily determined: cylinder structure form, installation method, connection method, etc.

Hydraulic system working schematic diagram

1. Its working principle is as follows: the hydraulic pump is driven by an electric motor and absorbs oil from the fuel tank. The oil flows into the hydraulic pump through the oil filter. The oil flows from the inlet low pressure to the pump outlet high pressure in the pump chamber. In the state shown in Figure 1-2 (a), it enters the left cavity of the hydraulic cylinder through the opening and stopping valve, throttle valve and reversing valve, and pushes the piston to move the workbench to the right.

2. The secondary piston is a one-way action structure. Under the action of hydraulic oil, the piston power extends, and the plunger retracts by its own weight when returning; the three-stage piston is a two-way action structure. Under the action of hydraulic oil, the third-level piston force extends and retracts. The lifting cylinder is equipped with three oil ports, PP2 and P3.

3. The working principle of the hydraulic system is to useThe liquid transfers energy, the liquid is pressed into the pipeline through the hydraulic pump, and the liquid is pressed into the hydraulic cylinder or hydraulic motor through the control of the valve to drive the mechanical movement. The workflow of the hydraulic system is as follows: the liquid is extracted and compressed by the hydraulic pump from the fuel tank and enters the pipeline.

4. Hydraulic system fast forward-work forward-fast retreat schematic diagram: The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission system and hydraulic control system.

5. Hydraulic schematic diagram What is the principle and working process of the hydraulic system? Many hydraulic novices know half of it. Today, through a few simple pictures, I will take you to understand the hydraulic transmission system step by step.(1) First of all, you have a fuel tank containing hydraulic oil, and the hydraulic oil is provided for the pump.

6. Hydraulic schematic refers to the graphic symbol used to express the interrelationship, working principle and working performance between various hydraulic components of the hydraulic transmission mechanism.

Determine the system scheme, formulate the hydraulic system diagram

Formulate the hydraulic system diagram. After the hydraulic system scheme is determined, you can select the relevant hydraulic basic circuit and configure the auxiliary circuit (or auxiliary components) to form the hydraulic system. General picture. To achieve the same work task, a variety of different hydraulic system diagrams can be formulated, and then analyzed and compared to select an optimal hydraulic system.

Determine the form of hydraulic actuator; 2) Conduct condition analysis to determine the main parameters of the system;3) Formulate a basic plan and a schematic diagram of the hydraulic system; 4) Select hydraulic components; 5) Verify the performance of the hydraulic system; 6) Draw a work diagram and prepare technical documents.

The working principle of the hydraulic system is to use the liquid to transfer energy, press the liquid into the pipeline through the hydraulic pump, and press the liquid into the hydraulic cylinder or hydraulic motor through the control of the valve, thus driving the mechanical movement. The workflow of the hydraulic system is as follows: the liquid is extracted and compressed by the hydraulic pump from the fuel tank and enters the pipeline.

The content of designing a hydraulic transmission system is to clarify the working requirements of the hydraulic transmission system, which is the basis for the design of the hydraulic transmission system, which is proposed by the user department in the form of a technical task book. Formulate a diagram of the hydraulic transmission system.

What aspects does the hydraulic system design involve?

A complete hydraulic system that can work normally should consist of the following five main parts: Power device: It is a device that supplies pressure oil to the hydraulic system and converts mechanical energy into hydraulic energy. The most common is the hydraulic pump. Actuator: It is a device that converts hydraulic energy into mechanical energy.

The overall layout and process requirements of the host, including the type of host movement completed by hydraulic transmission, the type and model of hydraulic actuator that may be used in mechanical design, the position of the actuator and the size range of its space, the degree of automation required, etc.

Hydraulic liquid (hydraulic medium): the working medium in the hydraulic system, usually using liquids such as oil as a medium for transmitting force and energy.Hydraulic pump: Responsible for converting mechanical energy into hydraulic energy and pushing liquid into the system through pressure.

What are the requirements for hydraulic system design?

6 Draw work drawings and compile technical documents; 7 Requirements for dustproof, explosion-proof, cold-proof, noise, safety and reliability; 8 Requirements for efficiency, cost and other aspects. Design steps The design steps of the hydraulic system are carried out in strict order, and each step is often interspersed with each other.

Customers' requirements for product functions and services must be met. Engineering machinery provides customers with not only the functions of the product, but also the after-sales service that supports these functions. Therefore, in the design process, it should not only target the different functional characteristics of the product, but also make the product have good maintenance convenience.

The requirements for the hydraulic system are primary and secondary safety pressure regulation protection, which meet the pressure control requirements of opening the door and closing the door to open the fluid-controlled one-way valve respectively, and play a role in safety protection. Direction control realizes the opening and closing of the door. In this function, the function of eliminating the change of direction shock is set to make the gate open and stop smoothly.

The function of the working medium used in the hydraulic press is not only to transmit the pressure, but also to ensure that the working parts of the machine are sensitive, reliable, long-life and less leakage.

Setting an energy accumulator in the hydraulic circuit can effectively absorb vibration, and setting up a damper near the vibration site can also effectively reduce the system vibration.

Suitable for drilling process requirements. ( 4) Number of hydraulic pumps: It is rare for hydraulic power head rock core drilling machines to choose a hydraulic pump.Generally, 3 hydraulic pumps are selected to form 3 independent hydraulic systems, namely the rotation and lifting system; the feed and auxiliary action system; and the mud pump system.
