As shown in Figures 1 and 2, lubricating oil metal fillings detection device provided by the invention, including metal fillings acquisition equipment and survey
Measure circuit.Metal fillings acquisition equipment includes an insulation crust 11 and the N number of sheet metal 12, N being installed in insulation crust 11
>=3, in the present embodiment, the quantity of sheet metal 12 is 9.It is parallel to each other between 9 sheet metals 12, and its spacing is according to metal fillings
Size is set, and in the present embodiment, the spacing between sheet metal 12 is 0.4mm.Flow direction is connected in insulation crust 11 parallel to metal
The lubricating oil of piece 12.Measuring circuit includes the power supply 21, current measurement module 22 and the N+1 resistance 23 that are sequentially connected in series, i.e. 10 electricity
Resistance 23.In the present embodiment, current measurement module 22 is ammeter, and the prevention of resistance 23 is 1k Ω, and the voltage of power supply 21 is 5V.
A conducting wire 24 is drawn between each two adjacent resistor 23, the other end of each wire 24 is connected with a sheet metal 12, that is, leads
The quantity of line 24 is identical with the quantity of sheet metal 12.
The operation principle of the present invention is as follows：
As shown in Figures 1 and 2, in the lubricating oil containing metal fillings is according to Fig. 2 direction shown in arrow out of insulation crust 11
When the sheet metal 12 in portion flows through, metal fillings can be intercepted by sheet metal 12, and several adjacent sheet metals can be by metal in sheet metal 12
Bits conducting, corresponding resistance 23 are shorted, total resistance value in measuring circuit are caused to become smaller, is measured in current measurement module 22
Electric current increases.According to the current value that current measurement module 22 measures, the quantity for the resistance 23 being shorted can be calculated, so as to judge
The number for the metal fillings that sheet metal 12 is captured gone out.22 detected current value of current measurement module is bigger, then the gold that device is captured
It is more to belong to bits.
When metal fillings is closely sized to or during more than gap 0.4mm between sheet metal 12 in lubricating oil, metal fillings is easily golden
Belong to piece 12 to intercept.
When on sheet metal 12 without metal fillings, electric current that current measurement module 22 measures for 5V/ (10 × 1k Ω)=
0.5mA.When having a small amount of metal fillings on sheet metal 12, and only so that a pair of of sheet metal 12 in ferromagnetic metal piece 12 turns on,
A corresponding resistance 23 is shorted, and the electric current that current measurement module 22 measures is 5V/ (9 × 1k Ω)=0.56mA.
When metal fillings so that N number of resistance 23 is shorted, the electric current that current measurement module 22 measures is 5V/ [(10-N) × 1k
Ω]。
When metal fillings is all filled in whole gaps in sheet metal 12, share 8 resistance 23 and be shorted, only remaining 2 resistance
23 are not shorted, and the electric current that current measurement module 22 measures is 5V/ (2 × 1k Ω)=2.5mA.
In conclusion the current range that current measurement module 22 measures is bigger to electric current between 2.5mA, is measured in 0.5mA,
Show that the metal fillings captured in lubricating oil metal fillings detection device is more.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, all should by the change or replacement that can be readily occurred in
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using the scope of the claims as
It is accurate.
