What is a pneumatic transmission comprehensive test bench?

The pneumatic transmission comprehensive test bench actually wants to talk about pneumatic transmission, not the test bench.

Because of the laboratory bench.

is standard, and pneumatic transmission we don't do, so the test bench.

I can explain.

Pneumatic transmission system is a technology that uses compressed air as the working medium to transmit energy and signals. It includes both drive technology and control technology. Pneumatic transmission technology (pneumatic technology for short) has developed rapidly and has penetrated into all fields of industrial production.

In particular, the transmission medium - air is convenient and pollution-free, so it is widely used in the textile, food, paper and electronics industries.

The working principle and composition of pneumatic transmission Pneumatic transmission is a form of transmission that uses compressor as the power source and compressed air as the working medium to transmit and control energy. Various components are composed of basic control loops with different functions, and several basic control loops are organically combined to form a complete pneumatic transmission system. Pneumatic transmission is to achieve a variety of production control.

Automatic control. One of the important means.

If you understand the working principle of a simple cylinder, you will understand the principle of pneumatic transmission.

Experience is for reference, thank you!

1. Machinery manufacturing industry. Including the clamping and handling of workpieces on the machining production line, modeling, tamping, and closing on the casting production line. In automobile manufacturing, automatic production lines for automobiles, automatic handling and fixing of car body parts, automatic welding, etc.

2. Electronic IC and electrical appliance industry. For example, it is used for the handling of silicon wafers, the insertion and soldering of components, and the assembly of household appliances.

3. Petroleum and chemical industry. The vast majority of automated processes that use pipelines to transport media are pneumatically controlled, such as petroleum refining and processing, gas processing, fertilizer production, etc.

4. Light industry food packaging industry. Including a variety of semi-automatic or fully automatic packaging production lines, such as wine, oil, gas canning, various food packaging, etc.

5. Robots. For example, assembly robots, painting robots, handling robots, wall climbing, welding robots, etc.

6. Miscellaneous. Such as vehicle braking device, door opening and closing device, particulate matter screening, torpedo missile automatic control device, etc.

3. The pneumatic device has simple structure, light weight, simple installation and maintenance, and is easy to use4. Good adaptability to the working environment, and can be safely and reliably used in flammable and explosive places

1. The pneumatic system has a large exhaust noise.

2. The working pressure is low, so the output force is small.

3. The working medium air itself has no lubrication, and it needs to be lubricated with oil4. The air is compressible, so the cylinder action speed is easily affected by load changes.

Here are just a few references.

Advantages: 1. It can achieve a wide range of stepless speed regulation in the process of operation.

2. Under the same output power, the hydraulic transmission device is small in size, light in weight, small in kinetic inertia and good in dynamic performance.

3. The hydraulic device works smoothly and has a small reversing impact, which is convenient for frequent reversing.

4. It is convenient to realize automatic working cycle and automatic overload protection, can achieve self-lubrication, and has a long service life.

5. Hydraulic components are standardized and serialized products, which are easy to design, manufacture and promote applications.

Upstairs is copied.

It is obviously copied (you can see it by looking at the last sentence, this question does not involve the advantages and disadvantages of hydraulic transmission). A complete hydraulic system, no matter how complex it is, consists of four parts (excluding hydraulic oil and other working media): power unit, actuator, control and adjustment device, and auxiliary device.

If you have any questions, you must answer the original, copy and report).

A complete copy of the hydraulic system consists of five raids.

Part composition, i.e., dynamic force element, actuator DU, control element, auxiliary element (accessory) and hydraulic DAO oil. The hydraulic system is mainly composed of five parts: power components (oil pump), actuators (cylinders or hydraulic motors), control components (various valves), auxiliary components and working medium.

1. Power element (oil pump) Its function is to convert the mechanical energy of the liquid into hydraulic pressure energy using the prime mover; It is the power part in the hydraulic transmission.

2. Actuators (cylinders, hydraulic motors) It is the conversion of the hydraulic energy of the liquid into mechanical energy. Among them, the oil cylinder does linear motion, and the motor does rotary motion.

3. Control components include pressure valves, flow valves and directional valves. Their function is to infinitely adjust the speed of the hydraulic motor according to the need, and to regulate and control the pressure, flow and flow direction of the working fluid in the hydraulic system.

4. Auxiliary components In addition to the above three parts, other components, including pressure gauges, oil filters, energy storage devices, coolers, pipe fittings and fuel tanks, etc., are also very important.

5. Working medium The working medium refers to the hydraulic oil or emulsion in various hydraulic transmissions, which realizes energy conversion through oil pumps and hydraulic motors.

Advantages and disadvantages of hydraulic transmission.

Hello friends! Upstairs is obviously copied (you can see by looking at the last sentence, this question does not involve hydraulic transmission.
