Technical field
The utility model relates to a kind of technology in sensing fluid flow field, specifically a kind of small pipeline for micrometeor
In, such as the traffic probe sensing device and its monitoring system of machine tool lubrication oil circuit.
Background technique
Good lubrication between all kinds of lathe movable parts is an important factor for influencing machining accuracy and lathe service life.Lathe
In process, need that rubbing between movable part could be made to providing lubricating oil incessantly between each slide unit of lathe
It wipes coefficient and maintains normal level.Therefore the lubricating oil fuel feeding situation in time in monitoring lathe lubricating system is most important.At present
Have no the automatic monitoring technical of micrometeor in the small pipeline for lubricating oil.
Utility model content
The utility model In view of the above shortcomings of the prior art, proposes that a kind of micrometeor detects sensing device and its prison
Examining system realizes mobility judgement inspection by the additional heat that liquid in detection microtubule is accumulated in the environment of specific setting
It surveys, the popularity for significantly improving accuracy and real-time compared to existing pressure detecting and using.
The utility model is achieved through the following technical solutions:
The utility model relates to a kind of traffic probe sensing devices, are set to special inside cavity, comprising: shell with
And it is fixedly installed on the intracorporal ceramic heating plate of shell and temperature-sensitive device, in which: between shell and ceramic heating plate and temperature-sensitive device
It is fluid to be measured between shell and cavity inner wall equipped with high-temperature insulation filler.When fluid is in flow regime in cavity,
The heat and the heat taken away of fluid generated by ceramic heating plate makes to detect intracorporal temperature, and to be substantially at dynamic constant, works as pipeline
Fluid stays cool in cavity when blocking, since the heat accumulation that ceramic heating plate generates will be so that temperature-sensitive device be examined
Rising sharply for temperature is measured, carrying out numberical range monitoring or the monitoring of change rate range by the signal that exports to temperature-sensitive device both can be with
Conversion obtains the flow regime of fluid in pipeline.
The utility model is further to a kind of monitoring system, comprising: source of lubrication, oil valve and as needed several
The above-mentioned traffic probe sensing device being arranged in parallel, in which: traffic probe sensing device is set on the output pipe of oil valve
Anywhere and by signal output line independent export monitoring information.

Connection.
Sealing ring 2 is preferably provided between the shell 3 and cavity 1.
The insulation filler 6 material small using high temperature resistant deformation coefficient, is realized by process for filling colloid.
When fluid is in flow regime in cavity, can be constantly carried away by the flow by the heat that ceramic heating plate issues
It is basic to maintain the flat perseverance of dynamic.When fluid stays cool in cavity, since heat accumulation enables temperature-sensitive device to detect
The variation of temperature, carrying out numberical range monitoring or the monitoring of change rate range by the signal exported to temperature-sensitive device can both convert
Obtain the mobility of fluid in cavity.
As shown in Fig. 2, a kind of flow monitoring system being related to for the present embodiment, comprising: the pump oil system as source of lubrication
