Shift to sample states.
When oil plant conveying device is as shown in embodiment 3 or 4, sample states then need include the first triple valve advance
It is access between hydraulic fluid port and the interior series connection mouth of group, and, it is access between the rear oil inlet and sampling oil export of the second communicating valve.
The application method of oil analysis system in the utility model embodiment, oil plant conveying device used or oil plant point
Analysis system has carried out corresponding scheme in embodiment 1 to embodiment 5 and has recorded, the advantageous effect of the utility model embodiment
Derivation.
Oil analysis system, the oil plant conveying device of oil analysis system and the user that utility model embodiment provides
Method is equipped with the second line segments in each sampling branch, and the second line segments are connected to filter, under non-sampled state, third
Line segments are in off state, and the sampling oil plant conveyed in real time from sampled point via the first line segments after the filter may be used
To be discharged along the second line segments, the sampling oil plant allowed in this way in filter maintains real-time update, that is, will not in filter
Retain residual oil plant when last progress oil analysis；
Third line segments are opened by flow control component, can be made when needing to carry out oil analysis via above-mentioned setting
The sampling oil plant of real-time update is delivered to via third line segments in pretreatment unit in filter；As seen from the above, pass through
The utility model can make the sampling oil plant before filter keep update in real time, to be effectively reduced previous sampling oil
The residual quantity in the pipeline of oil plant conveying device is expected, so that carrying out entering adopting for oil analysis instrument when oil analysis every time
Sample oil plant is consistent with the sampling oil plant acquired in sampled point, avoids the mixing with residual oil plant, and then also just improve
Precision of analysis when oil analysis.
Further, in the present invention, flow control component can also be set to including the first triple valve and the two or three
Port valve, and the valve control unit for controlling the two triple valves pass through valve control in this way, when being sampled
The break-make of unit processed controls, and can the sampling oil plant in each sampling branch be delivered to pretreatment unit respectively；Meanwhile may be used also
The gas generated in pipeline is discharged via waste oil outlet with being controlled by the break-make of valve control unit, to further
Precision of analysis when improving oil analysis, and be also avoided that in pipeline because there are the pressure caused by gas is different
Often.
Further, in the present invention, it sets flow control component to include the first triple valve, the second triple valve and
Three triple valves can be multiplexed waste oil outlet, while not influencing its discharge waste oil function, also by increasing third triple valve
Thus to access detergent line, so as to which cleaning solution by reversely pressurizeing, can be conveyed to carry out clearly pipeline into pipeline
It washes, the impurity from residual oil plant and the pipeline equipment that can further remove in oil plant conveying device pipeline, with into one
Precision of analysis when the raising oil analysis of step.
The apparatus embodiments described above are merely exemplary, wherein the unit illustrated as separating component can
It is physically separated with being or may not be, the component shown as unit may or may not be physics list
Member, you can be located at a place, or may be distributed over multiple network units.It can be selected according to the actual needs
In some or all of module achieve the purpose of the solution of this embodiment.
Through the above description of the embodiments, those skilled in the art can be understood that each embodiment can
It is realized by the mode of software plus general hardware platform, naturally it is also possible to pass through hardware.Based on this understanding, above-mentioned technology
Scheme substantially in other words can be expressed in the form of software products the part that the relevant technologies contribute, the computer
Software product can store in a computer-readable storage medium, such as ROM/RAM, magnetic disc, CD, including some instructions to
So that computer equipment (can be personal computer, server either network equipment etc.) execute each embodiment or
Method described in certain parts of embodiment.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
