Example 1:
when the P action is smaller than the P rating, the action pressure is lower than the rating pressure, that is, the air source needs to be supplemented, and the pressure of the default P air supply is greater than the P action, so that the pressure can be supplemented by itself due to the pressure difference, that is, the pressure control air pump 10 does not need to be started, and the air flow direction is as follows: the supplementary air source storage device 1 → the low pressure pipeline 4 → the pressure supplementing pipeline 6 → the action constant pressure air source supply device 2.
Example 2:
