Description
Technical field
The invention belongs to oil pipeline detection technique field, specifically a kind of oil transportation station pipeline oil product leak detecting device
And method.
Background technology
Pipeline is a kind of economic convenient means of transportation, has unique advantage in oil and natural gas conveying,
Outstanding behaviours is safe efficient, low consumption.Oil transportation station and long-distance oil ＆ gas pipeline are the aortic important components of China's energy,
Strategic position is particularly significant.Pipeline point more than long lines, because the particularity of use environment, degree of aging are different, plus inevitable
Corrosion, wear and the factor such as artificial destruction, pipe leakage occurs again and again.Especially leaked in the place such as flange connections
Probability it is bigger.The leakage of pipeline not only influences normal life, causes energy waste and economic loss, and by defeated Jie of institute
The danger and contaminative of matter, once accident occurs can also cause to the pollution of environment and huge life and property loss, therefore
Leak detection is an important pipeline fault detection technique.Leakage point has randomness, uncertainty.Monitoring oil product is let out at present
Leakage mode has：（1）Manual inspection, manually sees whether there is leakage point；（2）Gas detection sensing is set up in unit area
Device, principle is volatile substance after detecting gasoline, diesel oil leakage.
Manual inspection：Because leakage point has randomness, uncertainty, by artificial observation, workload is big, and omission point is more,
Can not in time, accurately find pipe leakage point.Gas detection sensor detection mode：Because of sensor detection is gasoline, bavin
The volatile substance of oil, because pipe laying environment is generally outdoor, is influenceed, gasoline, the volatilization of diesel oil by weather conditions such as wind and rain
Material is easily dispelled, and especially the volatility of diesel oil is extremely weak, gas detection sensor can not in time, accurately detect and let out
Leakage, and gas detection sensor is only able to detect pipeline and leaks, it is impossible to further detect leakage point, when detecting pipe
, it is necessary to by manually looking for leakage point when road is leaked.
