It sets, it is characterized in that: described device includes circulating detection pattern and acyclic detection pattern；
The oil sample storage section uses unique piston cylinder operator, and grease chamber is divide into upper part and lower part, and two parts are all sealings,
The support axis center of Piston spacer plates is connected with oil pocket lower part, and under circulating working mode, oil is flowed out from lower part solenoid valve F3, by
This support shaft returns to oil pocket, and this endless form is suitable for the constancy of volume of oil, and concentration can deaerate because of the equipment of detection, examine
Survey is that concentration slightly declines；Oil pocket top is controlled for acyclic operation with pressure, and acyclic method of operation mark oil concentration is constant,
Oil stream after detection enters above cavity, does not mix with sample；
The oil sample cyclic part can be such that oil gas in grease chamber is sufficiently mixed using circulation governor impeller C, guarantee oil dissolved gas content
Stabilization, extend the time of storage；Whole system is in storage in the stabilization for guaranteeing sample condition under confined conditions；
It is described to include the following: by the process of the automatic control system of core of ARM7
Oil inlet: using nitrogen oxygen synthesis gas to clean upper lower oil chamber before storage oil sample, when starting oil inlet, oil is entered by oil outlet,
Oil return opening opens solenoid valve F3 first to sky at this time, and solenoid valve F2, which is in, opens three-way magnetic valve first interface and three-way magnetic valve
The mode of third orifice, the state of three-way magnetic valve second interface choke-out, solenoid valve F1 are opened, and air pump B does not work；When
When oil return opening does not have bubble, switching solenoid valve F2 state opens three-way magnetic valve second interface and three-way magnetic valve third interface
The mode of connection, three-way magnetic valve first interface closure；Oil will push piston at this time, when displacement sensor, which detects, reaches the upper limit
Oil storage stops oil inlet；Solenoid valve F2 and solenoid valve F3 is closed when stopping, starting air pump B, solenoid valve F1 is to open at this time,
Air pump pressurization stops air pump B, and closed electromagnetic valve F1, guarantees when pressure sensor E detection pressure reaches 0.2Mpa
Oily room pressure is stablized；
Circulation: when store equipment be transported to scene when, detection before is first recycled, when by being run with oil circuit opposite direction into
Row circulation, a small amount of bubble of spilling is mixed into oil, guarantees the concentration of dissolved gas of oil sample, with the standard allotted in laboratory
Concentration is consistent；
Circular flow mode detects: after connecting pipeline at the scene, user's point hits control control flow, when starting the cycle over operation order,
Stop the operation of circulation governor impeller C, open solenoid valve F3 and solenoid valve F2, opens three-way magnetic valve first interface and threeway electromagnetism
The mode of valve third orifice；Solenoid valve F1 and air pump are according to the feedback signal of pressure sensor control and regulation upper piston area
Gas pressure guarantees grease chamber internal physical ambient stable；It is of less demanding that endless form detection is suitable for concentration variation, it is desirable that when long
Between run the scene of detection；
Acyclic method of operation detection: after connecting pipeline at the scene, user's point hits control control flow, starts acyclic operation order
When, stop the operation of circulation governor impeller C, open solenoid valve F3 and solenoid valve F2, opens three-way magnetic valve second interface and threeway
The mode of solenoid valve third orifice；Oil after detection degassing enters oil pocket top by solenoid valve F2, not mixed with crude oil sample
It closes, guarantees oil sample concentration, pressure is equally controlled by solenoid valve F1 and air pump；Acyclic mode is detected to be become suitable for concentration
Change and requires the scene high, long-time is not required to detect；
Oil extraction: user's point hits control control flow, and when starting oil extraction order, the pressurization for opening solenoid valve F3 and air pump B will be oily
The oil discharge of room lower part stops pressurization when displacement sensor D detects oil level 0, and oil outlet is closed with the nitrogen oxygen for being used to clean
It is connected at gas, clicks and continue, solenoid valve F1 closure opens the three-way magnetic valve second interface and threeway electromagnetism of solenoid valve F2 at this time
The mode of valve third orifice, top oil is drained；When displacement sensor D detects that top reaches maximum after 10s, open
The mode of unlatching the three-way magnetic valve first interface and three-way magnetic valve third orifice of solenoid valve F2, using gas cleaning oil
Internal gas is discharged for room, after a certain period of time, closes solenoid valve F2, opens solenoid valve F1 and air pump for piston and is pushed into 0 oil
Oil extraction process is completed in position.
