Description
Technical field
The utility model is related to industrial detection technical fields, are continuously supervised more specifically to a kind of pipe type oil water mixing
Survey device.
Background technology
Oil evaluation carries out oil pumping during the making a big purchase in large quantities of base oil, it is necessary to out of canning cart and in oil storage tank and unloads
Vehicle, and in the market in fluid transit link there are shady deal, a small number of evil mind businessmans can add water to make up the number into oil tank, and such oil is known as
Water filling oil.Therefore it is universal phenomenon to have water in oil tank, and each emptying, which has to pass through " steady oil control water " this operating instruction, to be prevented
Only accident occurs.
In order to find that oil is impregnated in water in transportational process in time in emptying in time, some new sensing technologies are answered
With there are mainly two types of methods for currently used on-line monitoring：First, utilize microwave attenuation principle, i.e., at microwave frequencies, water
Dielectric constant is more much higher than other substances, and most of substances are after containing moisture, and dielectric constant all can substantially increase, and microwave exists
Attenuation will increase when being transmitted in this medium, and the moisture content of material is can be obtained by by the attenuation for examining microwave.But this
Kind technology is in many aspects up for further perfect, and also generally existing testing result precision is relatively low at present, volume is big and uses
The deficiencies of complicated, therefore be not yet applied in emptying process monitoring；Second is that using capacity measurement principle, i.e., it is situated between using water and oil
Electric constant is different, and when water is mixed into machine oil, the dielectric constant of this mixed liquor and pure oil are significantly different, by the mixed liquor of wet oil
It is compared with the dielectric constant of pure oil, draws the capacitance of different value, then handled by circuit signal, it is aqueous that oil can be obtained
Rate score.This method since capacitance change is small, electrode plate structure design sampling area it is too small and must reach over to liquid measure and
Cause inconvenient for use, measurement inaccuracy.
《Technology of instrument and meter and sensor》One kind is discussed in (the 5th phase in 1996) " sensing probe of capacitance sensor "
Drum type brake capacitor plate structure is to form capacitor by two semi-circular cylindrical electrodes being close to outside circular non-metallic pipe, so
In use, the tested fluid contact of probe pole plate discord, when the fluid dielectric constant flowed through in nonmetal pipeline changes, is visited
Head capacitance changes therewith, can thus monitor the whether mixed water of oil for flowing through pipeline.Because capacitance type sensor self capacity value with
And capacitance variations value is all very small, the capacitance of capacitance sensor is generally pF grades, the so small capacitance of measurement, while it is desirable to
This small capacitance increment is detected by the measuring circuit specially designed, and has very big limitation to electrode plate structure design,
Two opposite necessary very littles of distance between polar plate, oil pipe road diameter is caused, which to be generally less than 10mm, could meet this test condition.
Such result is exactly oil pipe road diameter very little, it is impossible to meet the continuous monitoring of live emptying process, therefore also not obtain
Application well.
Through retrieval, Chinese Patent Application No.：2008200386948, the applying date：On August 18th, 2008, invention and created name
For：Electric impedance type crude, this application discloses a kind of electric impedance type crude, including being fixed on oil transportation
Secondary instrument outside pipeline disposes telemetry circuit in secondary instrument, and anchor ring excitation electrode pair is fixedly mounted in pipeline road, encourages electrode
To two electrodes between pipeline road in be fixedly mounted measuring electrode pair, telemetry circuit pumping signal output termination excitation electricity
It is extremely right, the sampling access port of the signal output termination telemetry circuit of measuring electrode pair.During work, impedance type crude oil water containing analysis
The pumping signal output terminal of instrument generates output voltage letter to excitation electrode pair output pulse current, at this time measuring electrode to being energized
Number, the signal is directly proportional to by the oil-water media impedance of pipeline road, and oil-water media impedance directly depend on it is therein
Moisture content, therefore measuring circuit can draw crude oil water content accordingly.But this application structure is complex, still can be further
Optimization.
