(1) The sealing ring is adjusted, the tightness of the air extraction barrel cover and the air extraction water barrel is checked, the manual air inlet valve is closed, and then the power supply is connected;
(2) When the intelligent detection controller detects that the water level in the air extraction water barrel is lower than the upper limit through the first water level sensor, the water discharge electric ball valve is closed, the air inlet electric ball valve is opened for air inlet, the water inlet electric ball valve is opened for water inlet, and if the water level reaches the upper limit, the original state is kept to be not working;
(3) When the intelligent detection controller detects that the water level in the air extraction water bucket reaches the upper limit through the water level sensor I, the water discharge electric ball valve is kept closed, the air inlet electric ball valve is closed, the water inlet electric ball valve is closed, and the vacuum pump is started to pump air;

(5) When the intelligent detection controller detects that the water level in the water storage barrel is higher than the upper limit through the second water level sensor, the air inlet electric ball valve is closed, and the water discharge electric ball valve is closed;
(6) In order to meet the geotechnical penetration test requirement, namely the water temperature needs to be higher than the set temperature, wherein the set temperature is 3-4 degrees higher than the air temperature, the intelligent detection controller is connected with the indoor air temperature sensor through a temperature data line to detect the indoor air temperature, the intelligent detection controller is connected with the water level sensor II through a water storage barrel water level meter detection line to detect the water temperature of the water storage barrel, and when the water temperature in the water storage barrel is lower than the set temperature, the heater is started to work; when the water temperature in the water storage barrel is higher than the set temperature, the heater stops working;
(7) The airless water in the water storage barrel is controlled by an external controller to control a pressurizing pump, so that the airless water in the water storage barrel is supplied to a position where water is required to be added in a permeation test;
(8) And (3) returning to the step (2) to restart airless water production when the intelligent detection controller detects that the water level in the air extraction water barrel is lower than the lower limit through the first water level sensor.
