Popular Science: Automatic Pressure Control Switch Acts Smart, Controls Pressure
Posted by thylertao on April 5th, 2019
When our bicycle tires are flat, we need to use an inflatable device to inflate the tires. Previously, artificial inflators were used, but now more and more bicycle repair points have electric air pumps. We just need to press the head of a long pipe on the air nozzle of the bicycle and it will fill up in a few seconds. Sometimes when we are inflating, we are frightened by the sudden sound of a motor. A closer look reveals that the other end of the pipe is connected to a pneumatic compressor. We inflate with a tube to make the pressure in the pressure vessel of the air compressor decrease. The motor of the air compressor is started to ensure the pressure of the gas in the container. But we didn't see anybody start up the compressor! Why does the air compressor work by itself? In fact, there is no mystery, but there is an automatic pressure switch on the air compressor to control the power supply of the motor of the air compressor.
