- The main pipeline must have an inclination of 1 ° ~ 2 ° for the drainage of condensate in the pipeline.
- The pressure drop of the pipeline must not exceed 5% of the pressure of the air compressor, so it is better to use a larger pipe diameter when piping.
- The branch pipeline must be connected from the top of the main pipeline, to prevent the condensed water flowing into the working machine. The air outlet pipeline of the compressor should add a check valve.
- When installing compressors in series, we should add a ball valve (or an automatic drain valve) at the end of the main pipe for condensation discharge.
- If there are air tank and dryer behind the compressor, the ideal piping should be compressor + air tank + front filter + dryer + other filters. In this way, the air tank can filter out part of the condensed water, and it also has the function of reducing the temperature of the compressed air. The lower temperature and less water content can reduce the load on the dryer or filter.
- If the system uses a large amount of air in a short time, we should install an air tank as a buffer, it can reduce frequent loading and unloading times, can reduce the number of control element actions, can maintain the reliability of the compressor’s operation. Generally, we can select an air tank with a capacity of 20%.
- Minimize the use of elbows and various valves in the pipeline to reduce pressure loss.
- The ideal piping system is that the mainline surrounds the entire plant so that two-sided compressed air can be used at any position. For example, when the air consumption of a branch line increases, the pressure drop can be reduced. Arrange appropriate valves on the ring-shaped trunk line for maintenance and cutting purposes.
