The full degas system of a kind of chromatogram high-performance total analysis on-Line Monitor Device of the present invention, its structural feature is; It comprises that oil strain returns oil system, online air content detection system, described oil strain returns oil system and comprises the oil circulation system, degassing tank, stirrer, storage tank, the stirring parts of described stirrer stretches in the degassing tank, described oil circulation system comprises cylinder, vacuum pump, the logical hydraulic fluid port of cylinder is connected with the end of oil-out up and down of transformer by oil line pipe, described vacuum pump is connected with the blow vent end of cylinder by oil line pipe, the blow vent end of cylinder also is connected with the carrier gas air-channel system by oil line pipe, the logical hydraulic fluid port of described cylinder also by oil line pipe respectively with degassing tank, storage tank is connected, the outlet of degassing tank is connected by oil line pipe with vacuum pump, the outlet of degassing tank is also by oil line pipe communication with carrier gas air-channel system, each oil line pipe is provided with solenoid valve, described online air content detection system is to comprise that oil strain returns the stirrer in the oil system, degassing tank, the outlet of degassing tank also is connected with pressure transducer and gas extractor by oil line pipe respectively, and each oil line pipe is provided with solenoid valve.
The full degas system of this structure, in use, two pipelines are connected to the end of oil-out up and down of transformer, utilize the cylinder in the full degasser, stainless-steel tube by connecting V2 and transformer is among the transformer oil suction cylinder space A, by the stainless-steel tube that connects V4 and transformer the transformer oil among the cylinder space A is returned in the transformer again, carried out this operation and once be the circulation primary oil sample, can be according to the number of times that how much comes Control Circulation that calculates dead volume.It is quantitative just to carry out oil sample after circulation is good, again fixed measured oil sample is sent into the degas chamber processing that outgases, differential pressure pick-up detects air content in the oil according to the pressure differential before and after the oil-feed, the gas of deviating from enters gas extractor, and the gas collection ball is again operating in the subsequent handling of the gas introducing monitoring device of deviating from.
Described gas extractor is a kind of gas collection ball, and the gas collection ball is connected with six-way valve.
Behind gas extractor, set up six-way valve, the gas of deviating from can be changed over to earlier and carry out in the six-way valve quantitatively, reach a certain amount of after, it is changed in the follow-up post piece-rate system again and separates.
At the storage tank top oil level switch is set.
At the storage tank top oil level detecting switch is set, when for several times or oil several times when being drained in the storage tank, oil level reach a certain height, and oil level switch will detect signal, then oil is sent back among the cylinder space A again, carries out follow-up operation.
Be provided with grease proofing device between degassing tank and the pressure transducer
Grease proofing device is set, can prevents that a small amount of oil that carries in the gas from damaging pressure transducer.
The objective of the invention is to realize by following approach.
In sum, the present invention has following advantage compared to existing technology:
1. per minute of the present invention is once capable of circulation, according to in-line volume calculation clean cycle number of times, the dead oil that just can finish pipeline in several minutes cleans, simpler compared with the external ebullator loop structure of traditional usefulness, circulation is with effective and rapid, simultaneously more saved ebullator, not only saved cost, and avoided because of the caused various faults of ebullator.Whole monitoring device compact conformation, the characteristics that price is low.
2. the oil strain of chromatogram high-performance total analysis on-Line Monitor Device of the present invention returns oil system, adopted and directly returned the method that oil combines with oil extraction, after returning oil earlier, again remaining oil sample is entered in the storage tank, after running up to some Deng the oil in the storage tank, it is sent back among the cylinder space A again, carry out follow-up operation.Therefore the present invention can avoid remaining oil sample to stay the ill effect that causes in the degassing tank, can improve to detect quality, prolong chromatographic column serviceable life, prolong transformer oil and use the time.
3. air content degasser of the present invention owing to set up pressure sensing gas, therefore can be measured the air content in fuel-displaced.
