[0037] (1) Airtightness and liquid resistance detection
[0038] Let's take the detected data of Jiujiang Yunshan gas station as an example:
[0039] Stop before the start of the test, all gasoline tankers are not allowed to refuel, and the diesel engine can work normally.
[0040] Close the return air pipeline valves under all gasoline dispensers, select the dispenser farthest from the oil tank line as the leak detection dispenser, and connect the pipeline with copper adapters to the detection port under the dispenser to ensure that the upper Tight airtight, the other end of the pipeline is connected to the outlet port of the oil vapor recovery tester.
[0041] Then connect the static grounding wire of the steel cylinder, and connect the other end of the copper braided static grounding wire to the static electricity removal sheet of the fuel dispenser to eliminate static electricity.
[0042] Connect the nitrogen pipeline, and connect the other end of the nitrogen pipeline ...
