How to choose the pneumatic fitting sizes according to demand?
Factors to consider when selecting pneumatic fitting sizes.
When selecting the pneumatic fitting sizes, a number of factors need to be considered, including pipe diameter, operating pressure and environmental requirements.
1. Pipe diameter:
The diameter of the pipe is the primary factor in selecting the pneumatic fitting sizes. Measure the inner and outer diameters of the fittings to ensure the selected pneumatic fitting match the fittings. Use an inner caliper to measure the inner diameter of the pipe fitting and an outer caliper to measure the outer diameter of the pipe fitting. According to the diameter of the pipe fitting, find the corresponding model of pneumatic fitting.
2. Working pressure:
The operating pressure of the pneumatic fitting is also a key factor to consider when selecting the size. Generally speaking, larger pneumatic fittings can handle higher pressures.
When working in a high pressure environment, the pneumatic fitting sizes should be selected to withstand the corresponding pressure. For example, when the working pressure exceeds a certain range, a smaller connector (such as 1/8 inch) may not meet the needs, and a larger connector (such as 1/4 inch or larger) is more suitable.
Therefore, it is necessary to refer to the pressure rating chart of the pneumatic fitting and select the appropriate pneumatic fitting sizes according to the working pressure.
3. Environmental requirements:
Environmental requirements also affect the pneumatic fitting sizes. For example, in an environment with limited space, you may need to choose a smaller pneumatic fitting to save space.
When quick connection and disconnection are required, quick connecting pneumatic fittings are a good choice. They usually have a small size and convenient operation.
Consider environmental factors such as the operating temperature of the pneumatic fittings, the corrosiveness of the medium, and select the fitting sizes and material that can adapt to these environments.
How to measure the pneumatic fitting sizes?
Measure the pneumatic fitting sizes is a critical step to ensure the correct selection and installation of fittings. The following is a detailed method for measuring the pneumatic fitting sizes:
1. Inner diameter measurement:
• Use an inner diameter caliper to insert into the inside of the pneumatic fitting and ensure that the caliper fits perfectly against the inner wall of the fitting.
• Read the inner diameter value displayed on the caliper. This value is the diameter size of the internal space of the pneumatic fittings.
2. Outer diameter measurement:
• Put the outer diameter caliper on the outside of the pneumatic fitting, making sure that the caliper fits tightly against the outer housing of the fitting.
• Read the outer diameter value shown on the caliper, which indicates the diameter size of the air fitting housing.
3. Thread size measurement:
• For pneumatic fittings with threads, use a thread gauge to measure the thread size.
• Insert the gauge tip into the threaded area of the fitting, making sure the gauge fits snugly against the fitting threads.
• Read the values of thread diameter and pitch shown on the thread gauge.
4. Notes：
• Ensure that measurements are made with tools that are highly accurate and have an appropriate measuring range.
• Be careful during measurement to avoid damaging the fitting or causing errors.
• Keep the fitting surface clean to ensure accurate measurement results.
