The connection principle and characteristics of pneumatic quick connector
The connection principle of pneumatic quick connector Under the action of pneumatic air pressure, the annular expansion generated by the inclined surface sealing ring of the pipe joint during the forward movement of the movable sleeve makes the sealing part inside the joint closely fit on the pipe wall, and the sealing part inside the joint is tightly attached to the pipe wall, and the gap between the pipe wall and the joint is A large friction force is formed to prevent the joint from being punched out due to the action of pressure, so as to realize the quick connection of the pipeline.

Selection conditions for quick connectors
1. The type and temperature of the fluid (please select the quick connector of the body material and the sealing material suitable for the type and temperature of the fluid) Depending on the fluid, the suitable body material and seal material are different. For example, quick connectors are air. Steel is recommended, and brass or stainless steel is recommended for water.

1. The air is easy to obtain and the working pressure is low, and the used air can be discharged on the spot without the need for recycling pipes. 2. The gas viscosity is small and the flow resistance loss is small, which is convenient for centralized gas supply and long-distance transportation.

Air pressure and classification of tire pressure gauges
If the air pressure is too low, it will increase the tire contact area and accelerate the shoulder wear. If the air pressure is too high, the tire cord will be excessively stretched and deformed, the elasticity of the carcass will decrease, and the load on the car during driving will increase.

Precautions during the use of pneumatic tools
If you want to use the air tool for a long time, then you have to maintain it to prolong the service life of the air tool. 1. Correct use of lubricating oil In order to maintain the best working performance of the air tool, it is best to add one to two drops of special oil for air tools before each use of the tool, which is very critical to the service life of the air tool.

Hardware tool knowledge: maintenance and maintenance of pneumatic tools
Six basic points of pneumatic tool operation and maintenance 1. Correct replacement gas supply system: The inlet pressure at the tool inlet (non-air compressor outlet pressure) is generally 90PSIG (6.2Kg/cm^2). Too high or too low will damage the performance and life of the tool. The air intake must contain sufficient lubricating oil, so that the air motor in the tool can be fully lubricated (you can place a white paper at the exhaust of the tool to check whether there is oil stains, normally there are oil stains).

Future Industry Rising Stars: Five Development Trends of Pneumatic Tools
Throughout the hardware tool industry, hand tools are the most traditional, and power tools are less expensive and easier to control than air tools due to their excellent control and operability. However, with the continuous innovation of science and technology, pneumatic tools have gradually become a rising star in the hardware industry by virtue of their simple structure, convenient maintenance, low cost, and long service life of pneumatic components.
