Some knowledge points of pneumatic tools

Pneumatic tools have been rapidly applied and developed in all walks of life. In the face of pneumatic tools themselves, they also have their own shortcomings, and there is no perfect object. But relatively speaking, the existence of any object has its advantages. Therefore, we should make good use of its advantages and strive to improve the disadvantages of pneumatic tools.
Advantages of pneumatic tools:
(1) As the working medium of pneumatic transmission, air is inexhaustible and convenient. It is directly discharged into the atmosphere after use, and will not pollute the environment.
(2) Good adaptability to work environment. The pneumatic transmission system is safe and reliable in harsh environments such as flammable, explosive, dust, radiation, strong magnetism, vibration and impact.
(3) The air viscosity is small, and the flow resistance is small, which is convenient for the centralized supply and long-distance transmission of media.
(4) The pneumatic control acts and responds quickly, and can reach the required pressure and speed in a short time.
(5) The manufacturer of pneumatic ratchet wrench believes that the pneumatic components are simple in structure, easy to process, long in service life, high in reliability, and easy to realize standardization, serialization and generalization.
The manufacturer of pneumatic ratchet wrench believes that the disadvantages of pneumatic tools are:
(1) Due to the high compressibility of the air, the movement speed of the cylinder is easy to change with the change of the applied load, and the stability is poor, which has a great impact on the position and speed control.
(2) At present, the pressure level of the pneumatic system (generally less than 0.8MPa) is not high, and the total output is not large.
(3) Since the working medium (air) has no lubricity, measures must be taken to lubricate the system with oil.
(4) The noise is loud, so it is generally necessary to install muffler.
Pneumatic tools mainly use the energy of compressed air provided by the air compressor as the power to make them work. In the early stage, most of China's pneumatic tools were imported from abroad, and the price was generally high. With the development and improvement of domestic technology, the price of pneumatic tools is reduced, and the after-sales service is more perfect. Customers can buy at ease.
Compared with electric tools, pneumatic tools also have many advantages. For example, under the same output power, pneumatic tools are lighter and more convenient to carry. Pneumatic tools are easier to maintain and can be used as long as the air source is connected; Pneumatic tools have strong water resistance, even if immersed in water, they will not be as deadly as electric tools. The adjustment of the pneumatic speed and output power of the tool is simple and can be easily controlled by the air supply valve. Pneumatic tools can save energy, reduce costs, have long service life and high safety.
In the future, the research and design of pneumatic tools will mainly meet the requirements of electronics, machinery, food, medicine, textile, chemical and other industries. The industrial automation equipment produced will develop towards high quality, high precision, pollution-free and long service life. At the same time, in order to improve production efficiency, the demand for high-speed and high-output pneumatic components will increase. In addition, mechatronics technology is the trend of industrial development. The mechatronics pneumatic system operated by microcomputer is becoming more and more popular, and the pneumatic components are also developing in the direction of low power consumption, miniaturization and lightweight.
