Embodiment Construction

[0032] Referring to Fig. 2 and Fig. 3, the capacitor has a pair of pole plates, that is, the M pole plate 13 and the N pole plate 14, wherein the M pole plate 13 is installed on the M base 11 correspondingly, and the N pole plate 14 is correspondingly installed on the N base Seat 12. The reference capacitor A and the sampling capacitor B are set to be exactly the same in shape and plate parameters.

[0033] Referring to Fig. 1, on the same threaded base 4, an airtight container 1 and a through-hole container 2 with an oil hole 3 are arranged side by side, the reference capacitor A is arranged in the airtight container 1, and the sampling capacitor B is arranged in the through-hole container 2 Among them, each of the two capacitors has an electrode connected to the sensor shell, one electrode of the reference capacitor A shown in Figure 1 is connected to the sensor shell through a wire 7, and the other electrode leads to the outside of the sensor. This structural form The sens...

Abstract

The invention provides a random detection method and a detection sensor of the performance of engine lubricating oil, which is characterized in that the invention is provided with a reference capacitor A and a sampling capacitor B, respectively; the capacitors have the same pole plate parameters, and are in the same ambient temperature; the initial sample is taken as the media of the reference capacitor A, and the lubricating oil to be detected is taken as the media of the sampling capacitor B; an electronic circuit is used to detect the difference value of the capacity of the reference capacitor A and the capacity of the sampling capacitor B; an alarm is given when the difference value of capacity reaches the set value. The invention can give an alarm immediately when the moisture content in grease exceeds the limit and the lubricity of the grease degrades.

Description

technical field [0001] The invention relates to a lubricating oil performance detection device for a fuel engine and a gas engine. More specifically, it is a device that can track and detect when the water content of lubricating oil increases or other reasons cause the performance of lubricating oil to decline. Background technique [0002] Fuel engines and gas engines generally choose whether to change the lubricating oil according to the mileage or running time. Although, the user can actively check the oil level and color of the lubricating oil to determine whether there is a lack of oil and whether the water content of the lubricating oil exceeds the standard. However, according to the user's experience, it can only be found when the lubricating oil has a large water content or poor performance. For smaller water content, it is difficult to find. [0003] As we all know, water has a great influence on oil, which can accelerate the oxida...
