Method and instrument for detecting oil gas recovery system of gas station

Abstract

The invention relates to a method and instrument for detecting an oil gas recovery system of a gas station, in particular to an oil gas recovery detecting method and an intelligent detecting instrument, wherein the detecting method comprises the step of detecting the tightness, the liquid resistance and the gas liquid ratio of the oil gas recovery system of the gas station according to the programmed sequence by adopting a flow and pressure matching mode, and the detection data is automatically saved and can be printed on the spot or transmitted to a computer; and the intelligent detecting instrument comprises an anti-explosion circuit system and a closed gas path system, wherein the anti-explosion circuit system comprises a power supply source, a Roots flow sensor, a digital pressure sensor, a display screen, an input keyboard, a single chip microcomputer processing module, a data memory, a printer interface, a data transmission interface and the like, the closed gas path system comprises a flow sensor, a pressure sensor, a pipe fitting, a flexible pipe and a quick joint, and the circuit system and the gas path system are matched with a panel to be integrally installed in a box body. The detecting method of the invention is distinct, flexible, simple and convenient; and the detecting instrument of the invention has compact structure and perfect functions and can be carried, used, maintained and repaired simply and easily.

Description

technical field [0001] The invention belongs to the detection method and the equipment of the realization method of the oil gas recovery system of the gas station, and particularly relates to the programmed, standardized, automatic and intelligent detection of the airtightness, liquid resistance and gas-liquid ratio of the oil gas recovery system. Background technique [0002] With the rapid development of economy and society, the number of automobiles and gas stations in my country is increasing day by day. The pollution problem of gas stations has been widely valued by the society. The oil and gas spilled during vehicle refueling and oil transportation will damage the environment and waste resources. become an urgent problem to be solved. Oil and gas recovery transformation of gas stations is the general trend and is imperative. Oil and gas recovery at gas stations is divided into two stages: oil collection and oil delivery, which are called the first and second stages of ...
