Description
Technical field
The utility model provides the online oil liquid monitoring sensor of monitoring device field application.
Background technology
Lubricating oil in use for some time, especially large scale equipment and oversize vehicle, due to introduced contaminants intrusion and
Oxidation itself, cohesion, hydrolysis and the reason such as decompose, oil product will go bad, additive losses, oily viscosity, acid number, impurity contain
The physicochemical properties such as amount, moisture will send out change, and performance can decline, if being continuing with rotten oil, be deposited in oil
Thing drastically increases, and the service behaviour of equipment declines, and parts wear aggravation even results in system and occurs catastrophe failure.Conversely, such as
Fruit renews oil in the case of oil is used normally, will result in the wasting of resources.Therefore, in order to avoid above mentioned problem, just having must
The behaviour in service of lubricating oil is monitored in real time, the degree of metamorphism of oil is weighed by certain Monitoring Data, it is determined that reasonably
Change oil opportunity.
At present in engineering in use, being mainly monitored using off-line technology to performance, the state of oil, the oil of collection in worksite
Sample is sent to the test that physical and chemical index is carried out after monitoring center and abrasive grain content is determined, and conventional instrument has kinematic viscosity measure
The analytical instrument such as instrument, naphthaometer, mechanical admixture analyzer, moisture teller, these instruments have measuring accuracy height, test
The standard compliant advantage of method, but there is following deficiency：
（1）It is bulky, it is only suitable for carrying out off-line analysis in laboratory environment, is not suitable for the test of online or field assay；
（2）Process from spot sampling to laboratory need to take a long time, and be unsatisfactory for the requirement of real-time；
（3）Instrument cost is high, also high to maintenance and operation technical requirements, is not suitable for field monitoring.
The content of the invention
In order to realize oil liquid monitoring, the utility model provides online oil liquid monitoring sensor.The sensor passes through exhausted
Edge oil pipe outer surface sets battery lead plate, and by setting of the battery lead plate on insulation oil pipe, monitoring oil stream capacitance variations value solves oil
The technical problem of liquid on-line monitoring.
The utility model solves the scheme that is used of technical problem：
Shangyang battery lead plate and upper negative electricity pole plate, lower anode electrode plate and lower negative electrode are respectively equipped with insulation oil pipe two sections
Battery lead plate.
Shangyang battery lead plate and upper negative electricity pole plate constitute a pair of electrodes plate；
Lower anode electrode plate and lower cathode electrode plate constitute a pair of electrodes plate；
Shangyang battery lead plate and lower positive plate are staggered in 90 °.
Gap is left between battery lead plate；
Radome is housed on the outside of insulation oil pipe.
Sensing line is connected on every a pair of battery lead plates；
Shangyang battery lead plate and lower positive plate are staggered in 90 °.
The radome is cylindrical shape, is covered on the outside of insulation oil pipe.
Good effect, the utility model can be achieved the effect that after：（1）Monitored on-line by fluid, can and
When understand in the pollution situation with fluid, as sealing ring, cleaner fail, and handle and repair in time the reason for analysis oil contamination
Just, failure is made to eliminate in bud.
（2）Monitored on-line by fluid, grasp is reasonably changed oil opportunity, become " changing oil on schedule " mode into " Change oil according to oil quality ",
Manpower, financial resources, material resources are saved for factory.It is demonstrated experimentally that being monitored using contamination level of oil liquid can make the drain period of fluid extend 2 times
More than.
（3）Monitored on-line by fluid, according to the change of metal worn particle content, the working condition of equipment is made and tentatively sentenced
It is disconnected, accomplish Predictive Maintenance and actively repair, so as to extend machine service life and failure time interval, improve reliable
Property and reduction maintenance cost.
（4）By detecting the analysis and accumulation of data, trend analysis is progressively set up, efficiency and the judgement of analysis result is improved
Accuracy rate.
Suitably as online oil liquid monitoring sensor device application.
Brief description of the drawings
Fig. 1 is the utility model electrode arrangement states figure；
Fig. 2 is the utility model battery lead plate expanded view；
Fig. 3 is that the utility model electrode sets vertical view state figure.
In figure, 1. insulation oil pipes, 2. Shangyang battery lead plates, 2.1, upper negative electricity pole plate, 3. times anode electrode plates, negative electrode under 3.1.
Battery lead plate.
Embodiment
According to the figure, Shangyang battery lead plate 2 and upper negative electricity pole plate 2.1, lower anode are respectively equipped with the insulation two sections of oil pipe 1
Battery lead plate 3 and lower cathode electrode plate 3.1.
Shangyang battery lead plate and upper negative electricity pole plate constitute a pair of electrodes plate；
Lower anode electrode plate and lower cathode electrode plate constitute a pair of electrodes plate；
Gap is left between battery lead plate；
Radome is housed on the outside of insulation oil pipe.
Sensing line is connected on every a pair of battery lead plates.
Upper anode plate is staggered with lower 90 ° of positive plate.
The radome is cylindrical shape, is covered on the outside of insulation oil pipe.
It is of the present utility model to use：
Insulation oil pipe is linked on oil piping system, battery lead plate is arranged by design requirement, battery lead plate is by sensing line and prison
Survey between device connection, pole plate and form capacity effect, according to the change detection value of capacitance, judge cleannes oily in oil pipe, according to
It is secondary to judge whether oil is dirty, it is dirty that what degree arrived.
Feature：
Because battery lead plate is two sections, and it is staggered, so sensing equilibrium to oil circuit online monitoring data, is conducive to extracting
Oily capacitance in oil circuit, judges the clean-up performance of oil, when clean-up performance drops to setting value, monitoring device is pointed out, certainly
It is fixed whether to change fresh oil.
Oil described in the utility model is the liquid lubricant of motion state.
Two pairs of the present utility model semicircle pole plate alternating expression capacitance sensors, regard lubricating oil change in dielectric constant as oil
Liquid deteriorates monitoring index.Decline and be not easy to the traditional oils such as cleaning so as to avoid sensitivity caused by pole plate accumulation of pollutants
The drawbacks of liquid monitors capacitance sensor.The sensor just can know the dirt of fluid by monitoring the change of fluid dielectric constant
Dye and decay situation.
