Pneumatic vs. hydraulic drives

2024-10-28

In the field of automation, pneumatic drives and hydraulic drives have different applications and performance characteristics. Pneumatic drive systems are commonly used in industrial fields such as petrochemical, natural gas processing, mining, etc., especially in harsh environments or where rapid operation is required. Hydraulic drive systems are used for heavy duty industrial valves, such as steel mills, large dams, ships, etc., especially where high torque output is required. In this article, we will take the motor as an example to introduce the difference between the two.

1.Pneumatic drive motor

(1) Principle of operation: ① Air supply: the air motor needs to be connected to an air source, usually a compressed air source. Compressed air is piped to the air inlet of the air motor. ② air supply: the air motor needs to be connected to an air source, usually a compressed air source. The compressed air is piped to the air inlet of the air motor. ③ Air supply: The air motor needs to be connected to an air source, usually a compressed air source. The compressed air is piped to the air inlet of the air motor. ④ Air supply: The air motor needs to be connected to an air source, usually a compressed air source. The compressed air is piped to the air inlet of the air motor. ⑤ Air supply: The air motor needs to be connected to an air source, usually a compressed air source. The compressed air is piped to the air inlet of the air motor.

(2) product features: volume, light weight, suitable for more compact industrial equipment; does not produce sparks, completely explosion-proof, high fire resistance; to solve the problem of burnt motor; more suitable for high temperature, humidity, dust and other harsh environments such as industrial and mining use; through a simple pneumatic regulator or flow regulator valve can be realized stepless speed and torque change; can be used for a long time and will not be damaged; self-cooling effect, can be used in high temperature occasions. It has self-cooling effect and can be used in high temperature environment.

2. Hydraulic drive motor

(1) Working principle: hydraulic drive system uses hydraulic oil as the working medium, through the hydraulic cylinder or hydraulic motor drive valve. Hydraulic motor working principle is that the hydraulic oil through the control valve into the cylinder, the formation of pressure difference between the two sides of the cylinder, the pressure difference to promote the drive shaft rotation, the hydraulic energy into mechanical energy.

(2) Product features: ① Flexible arrangement, can be easily and flexibly arranged according to the needs of various components. ② Small size, light weight, small motion inertia, fast response speed. ③ Wide range of speed regulation: a wide range of stepless speed regulation can be realized. ④ High degree of automation, easy to realize the automation of the machine, and after combining with the electric control part, higher degree of automatic control can be realized. ⑤ High manufacturing precision is required and the price is expensive. It is not easy to find out the reason when it breaks down, and the use and maintenance require a high level of technology.
