Abstract
The utility model discloses a pocket type infrared motor oil detector. The pocket type infrared oil detector is mainly characterized in adopting an infrared detection circuit to detect the impurity content in motor oil; adopting a moving river table to directly display the impurity content in motor oil. The utility model with the advantages of simple structure, low cost, high reliability, and little error is particularly suitable for detecting the quality of the motor oil used for engines.
Description
The utility model relates to a kind of pocket infrared ray machine oil detector.
At present, the method for people's discrimination machine oil quality mainly contains these two kinds of observation method of naked eye and instrument detecting methods.Though observation method of naked eye is simple, personal error is big, poor reliability; The instrument detecting method is than the observation method of naked eye good reliability, and error is little, but needs to be equipped with a large amount of detecting instrument and full-time tester and place, and the instrument use is complicated, and the test duration is long, brings difficulty also for applying of instrument detecting method.
The purpose of this utility model provides a kind of simple in structure, with low cost, easy to use, good reliability, the pocket infrared ray machine oil detector that error is less, to take into account the advantage of observation method of naked eye and instrument detecting method, improve the ratio of performance to price of machine oil detecting instrument.
The utility model adopts the oil film detection method, and the absorbance of its machine oil is:
Absorbance=KMD
In the formula: K-coefficient M-impurity concentration D-oil film thickness
And oil film thickness is:
D=K
2· (d)/(W) ·P
In the formula: d-impurity granularity, W-pressing plate weight, P-engine oil viscosity
By above two formulas as can be known, when engine oil viscosity changes when little, absorbance is proportional to impurity concentration and impurity granularity.So we can think that absorbance and impurity concentration and impurity granularity are linear.
Based on the utility model of above-mentioned theory design, adopt opto-electronic conversion, linear amplification, meter reading directly shows the impurity content of tested machine oil.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 cuts open figure for master of the present utility model looks;
Fig. 2 cuts open figure for the office of overlooking of the present utility model;
Fig. 3 is an electrical schematic diagram of the present utility model.
Referring to accompanying drawing, the utility model is made up of microswitch 1, test board 2, top board 3, infraluminescence pipe 4, moving river table 5, infrared receiving tube 6, lower house 7, circuit board 8, sponge 9, stacking battery 10, upper shell 11 etc., the upper surface of described upper shell 11 has display window, moving river table 5 is housed in the window, the side has the detection slot, is plugged with the sample that is made of check-out console 2 and top board 3 in the slot and transplants a cutting; In the upper and lower correspondence that detects slot infrared receiving tube 6 and luminotron 4 are housed, microswitch 1 is equipped with in the termination; In upper shell 11, circuit board 8 and stacking battery 10 also are housed by holder; Be bonded with sponge 9 at lower house 7 corresponding to stacking battery 10 positions; Last lower house 11,7 is connected as a single entity by screw.
Principle of work of the present utility model is as follows: in the detection that will scribble sample machine oil transplant a cutting to insert detects slot, and when touching microswitch 1, detector is started working.By infrared transmitting tube D
2The infrared light of launching after tested plate 2 and oil film to be measured and top board 3 by infrared receiving tube D
1Receive, be transformed into behind the electric signal by adjustable resistance W
1Send into by integrated circuit (IC)
1And IC
2The amplifier that constitutes carries out linear amplification, exports corresponding electric signal then and drives moving river table M, makes the needle deflection on its dial plate, demonstrates the reading of representing the impure amount of machine oil.
Using method of the present utility model is as follows: at first extract sample out and transplant a cutting from upper shell 11, take away top board 3 from test board 2, one droplet machine oil to be measured is instiled in the middle of test board 2, gently top board 3 is covered on oil droplet then, sample is transplanted a cutting to insert detect in the slot, and slightly firmly the sample cutting is inwardly pushed away, make microswitch 1 action, connect the detector circuit, and then make river table 5 needle deflection, treat that pointer gets final product reading after stablizing on the dial plate.
The utility model is simple in structure, with low cost, dependable performance, detection error are little, is specially adapted to the quality of detection of engine with machine oil.
