Can the air pump be converted into an air compressor?

Safety valve is used to relieve pressure and prevent explosion. If you want a pressure of 5 kg, set it to 5.5 kg and open the safety valve. There is no problem with the modification. You need to install a pressure switch, otherwise you don't know how much pressure will stop. In addition, pay attention to the connection of pipe threads. It is better to search the drawings of air compressor system than to draw a tiger with a cat. Although the machine is small, we should pay attention to safety.

The pipe thread is the joint thread connecting your air pump pipeline with the air storage tank, and the pressure switch of the safety valve should be connected to the air storage tank with the thread. You can weld a pressure vessel yourself, inflate it after welding, and soak it in water to see if there is any leakage. You are not afraid of ugliness. The key is safety.
