The use method of the gas replacement and detection device is as follows: firstly, calibrating a nitrogen analyzer (measuring range: 70% -99.99%; precision: 98-99.99 + -0.03% N)2) The method comprises the steps of respectively connecting a test pipeline with external atmosphere and pure nitrogen (an inflation gas source) after starting up and stabilizing for 3 minutes, turning a knob of a nitrogen analyzer to a calibration gear, and observing whether a test result is 79 percent (the content of nitrogen in the air) and a nominal value of the gas source. In the manual mode (the control switch on the operation panel is turned to manual operation in advance), a vacuum pumping switch is turned on, and a vacuum pump operation indicator lamp is turned on; when the pressure in the box body is lower than the lower limit of the pressure, the pressure gauge feeds back data to the PLC, and the PLC sends out an instruction to stop the operation of the vacuum pump; opening a nitrogen filling switch to fill nitrogen into the box body, feeding back data to the PLC by the pressure gauge when the pressure in the box body is higher than the upper limit of pressure, and sending an instruction to the solenoid valve to cut off the gas filling pipeline by the PLC to stop filling gas; when the purity and pressure of the nitrogen in the box body both meet the index requirements, the 'standard reaching indication' lamp is lightened to prompt the completion, and the manual vacuum-pumping and nitrogen-filling operation is stopped.
In the automatic mode (the control switch on the operation panel is turned to the automatic state in advance), the start button is pressed, and then the automatic running indicator lamp is turned on. Need not artificial intervention among the whole automatic operation process, PLC controller and each sensor cooperate jointly, accomplish bleeding, aerify and pressure, nitrogen gas purity test, the adjustment in the box automatically, stop automatically up to the back of reaching standard, light "indicating to reach standard" lamp is accomplished in order to indicate simultaneously. If the stop button or the scram button is pressed during the period, the operation is automatically stopped, and the indicator light is turned off. In the pressure fine adjustment stage at the end of the automatic mode, as the gas in the box body has a balance and stability process during inflation and air exhaust, the standard-reaching indication lamp can be turned on or off for a while and can be stabilized after a short time of minutes.

The principle that the roll angle of the tank body is fixed to be 90 degrees every time is as follows: each hoop and the corresponding bracket are connected through two connecting and fixing plates 3-8 with 90-degree included angles and locked by bolts, 4 screw holes are uniformly distributed on the hoop along the circumference, the bolts must penetrate through the 4 screw holes to lock the hoop and the bracket through the connecting and fixing plates, and the tank body is limited to be fixed and locked only by integral multiples of 90 degrees once per rotation.
In practice, after the storage and transportation container (the tank body is fixed in the container) is transported or stored for a period of time after the gas replacement is finished, the rolling operation is often required, and the specific operation is as follows: firstly, removing 4 groups of fixed seat assemblies on a box body, then integrally pulling a tank body and a support frame vehicle to slide out of the box body through a movable guide rail and a stranded cable frame vehicle, removing a hoisting shaft and a bolt on a connecting and fixing plate, installing a rolling handle on a clamp, rotating the rolling handle to drive the tank body to rotate 90 degrees, aligning a screw hole on the connecting and fixing plate with a screw hole on the clamp, installing the bolt to lock the clamp and a bracket (the tank body is also locked), and removing the rolling handle; after the tank body is rolled, the lifting shaft is installed, the tank body is pulled to slide into the box, the fixing seat assembly is installed to seal the box door, and the gas replacement and detection device is used again for gas replacement. The tank body has specific requirements on rolling: firstly, rolling the tank body for 4 times along a certain direction, wherein the rolling is carried out for 90 degrees each time; then the tank body is rolled for 4 times in sequence along the opposite direction, and the tank body is rolled for 90 degrees each time; and finally, repeating the operations of the first step and the second step. This rolling is done to counteract or eliminate axial displacement of the can body. After the tank body is filled and rolled, the tank body needs to be subjected to gas replacement and detection operation, but the gas in the tank needs to be checked in a sampling mode in the transportation or storage process, and once the nitrogen content or the pressure is unqualified, the gas needs to be pumped or inflated immediately until the nitrogen content or the pressure is qualified.
