Embodiment 1

[0024] This embodiment discloses a lubricating oil film level measuring instrument, which is suitable for performing each method step described in the present invention, so as to achieve expected technical effects. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment.

[0025] According to a preferred embodiment, see figure 1 , 2 , the lubricating oil film level detector may include a capacitive sensor 2 arranged in the oil tank 1 , a measuring module 3 connected to the capacitive sensor 2 and a processor 6 connected to the measuring module 3 . Preferably, the measurement module 3 may also include an operational amplifier and an analog-to-digital converter. Since the output signals and their differences generated by different lubricating oil compositions are very small, they can be amplified by a DC amplifier circuit, and then converted into digital ...

Embodiment 2

[0037]This embodiment may be a further improvement and / or supplement to Embodiment 1, and repeated content will not be repeated here. This embodiment also discloses a method for measuring the oil film level of lubricating oil, which can be realized by the lubricating oil film level measuring instrument of the present invention and / or other replaceable components. For example, the method of the present invention is realized by using each component in the lubricating oil film level tester of the present invention. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments may serve as supplements to this embodiment.

[0038] According to a preferred embodiment, a method for determining the level of lubricating oil film, the method may include: using a capacitive sensor 2 arranged in the oil tank 1 and a measurement module 3 connected to the capacitive sensor 2, wherein the measurement module 3 may inclu...

Embodiment 3

[0053] This embodiment may be a further improvement and / or supplement to Embodiment 1, 2 or their combination, and repeated content will not be repeated.

[0054] In this embodiment, an optional process of measuring the oil film level of gasoline engine oil is taken as an example.

[0055] Continuously short press the confirmation button 3 times;

[0056] The interface displays gasoline engine oil, diesel engine oil, transmission oil and hydraulic oil;

[0057] Select the gasoline engine oil product by touching the buttons up, down, left, and right;

[0058] Press the confirm button;

[0059] The words please put in synthetic oil appear;

[0060] Use a glass rod or a pipette to drop 3-4 drops of calibration oil whose oil film level is selected as 100% into the oil tank;

[0061] Press the confirm button;

[0062] The words in calibration appear;

[0063] After the calibration is completed, the words "Calibration Complete" will appear, and the words "Please put in the bas...

Abstract

The invention relates to a lubricating oil film level tester and a test method thereof. The tester includes a capacitance sensor arranged in an oil tank and a measurement module connected to the capacitance sensor. The measurement module includes a processor configured to is: Obtain the first measured value ε for the first medium representing the lowest oil film level min , to obtain a second measurement ε for the second medium representing the highest oil film level max , to obtain the third measured value ε of the third medium measured by the capacitive sensor x , calculate the oil film level of the third medium and feedback it to the user through visual and / or auditory means, where the first measured value ε min , the second measured value ε max and the third measured value ε x They are proportional to the first dielectric coefficient of the first medium, the second dielectric coefficient of the second medium, and the third dielectric coefficient of the third medium, and the proportional ratios are the same. The third medium is unused lubricating Oil.

Description

technical field [0001] The invention relates to the field of lubricating oil detection, in particular to a lubricating oil film level measuring instrument for quickly measuring lubricating oil composition, structure and other microscopic characteristics and oil film level and a measuring method thereof. Background technique [0002] At present, the lubricating materials used to ensure the normal operation of mechanical equipment are basically prepared from Class 5 base oils released by the American API. Type 5 base oils include mineral oils for Type 1-3 oils, polyalphaolefins for Type 4 oils, and base oils other than Type 1-4 base oils (synthetic hydrocarbons, esters, ethers, silicone oil, etc.). The production process of Class 1 base oil is basically based on physical processes without changing the hydrocarbon structure, and the quality of the produced base oil depends on the content and properties of the ideal components in the raw material. Therefore, the performance of...
