Embodiment 1

[0020] A gas station oil gas recovery comprehensive tester, such as figure 1 As shown, including the chassis base, front panel, battery pack, keyboard circuit board, main control board, LCD display, pressure sensor, flow sensor, the pressure sensor is connected to the gas pipeline of the flow meter sensor interface through the pressure sensor interface, and the flow rate The sensors are connected in series into the gas pipeline of the flowmeter sensor interface, and the connected gas pipeline is seated on the bottom plate of the battery pack of the instrument through the bracket; the instrument circuit board, instrument display circuit board, and instrument key circuit board are installed on the front panel of the chassis frame Paste the nameplate of the instrument on the upper cover, pass the air outlet of the air pipeline of the flowmeter sensor interface through the reserved opening on the right cover, and install the gas outlet at the air outlet of the air pipeline of the f...

Embodiment 2

[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 ...

Abstract

The invention relates to an oil gas recovery comprehensive tester for a gas station, and mainly solves the problems of inconvenience in carrying and low detection speed in the prior art. The inventionprovides an oil gas recovery comprehensive tester for a gas station. The tester comprises a case base, a front panel, a battery pack, a keyboard circuit board, a main control board, a liquid crystaldisplay screen, a pressure sensor and a flow sensor, the pressure sensor is connected to a flowmeter sensor interface gas circuit pipeline through a pressure sensor interface, the flow sensor is connected into the flowmeter sensor interface gas circuit pipeline in series, and the connected gas circuit is seated on a bottom plate of an instrument battery pack through a support; and the instrument circuit main board, the instrument display circuit board and the instrument key circuit board are arranged on the front panel of the case frame. By adopting the technical scheme, the problems are better solved, and the oil gas recovery device can be used for oil gas recovery of a gas station.

Description

technical field [0001] The invention relates to a comprehensive tester for oil gas recovery at a gas station. Background technique [0002] In today's society, the volatile gases emitted by gas stations have a greater impact on the urban environment, because there are organic components containing a lot of oil, such as benzene, toluene, xylene, ethylbenzene and other hydrocarbons, and most of these organic substances have been It is recognized as harmful to the human body; in addition, the unsaturated hydrocarbons containing a large proportion of oil in the volatile gas of oil and gas will undergo physical and chemical reactions with nitrogen oxides in the air after being irradiated by ultraviolet rays, forming photochemical smog and the greenhouse effect, which will destroy the ozone layer , has a great pollution effect on the ozone layer, and photochemical smog is also one of the important causes of smog. The volatilization of oil and gas will also cause the surrounding ai...
