The purpose of this utility model is to overcome the existing deficiency of measuring the lubricating oil analysis instrument of transmittance variation, detect control methods based on GB7607-87 appendix A " I. C. engine oil filter paper spot test method " and transmittance, improve the measurement lattice of analyser, a kind of mass-synchrometer that can detect middle-and-high-ranking lubricating oil is provided.
The utility model is achieved in that by cabinet, measurement lattice, light transmission piece, testing circuit, nixie display to be formed, the measurement lattice of design are square casings that electric light source and light sensor are housed on its two side relative position in opposite directions, in have movingly suit square core, be provided with the slip push pedal that is used for colourless light transmission piece and black transparent sheet location in the fuse, the push pedal back side is supported by the fuse inwall through spring, and push pedal and fuse two side are incident upon at electric light source on the light path position of light sensor and have the printing opacity through hole.
Light transmission piece is two rectangular plate making with colourless transparent material, wherein one of whole clearing is colourless light transmission piece, another piece is the black transparent sheet, on the surface, leave the circular photic zone, all the other coating thickness be the 0.03-0.20 millimeter every optical coating, the photic zone edge has annular store oil groove, and two light transmission piece can together be inserted between push pedal and the fuse inwall.
Testing circuit is by power circuit, zeroing circuit, transfer the full scale circuit, signal amplifier, A/D converter and nixie display are formed, wherein the output of light sensor connects the low input end of A/D converter through signal amplifier, at the input and the output terminal of signal amplifier and connect the partial pressure type of forming by resistance and potentiometer and transfer the full scale circuit, the output termination nixie display of A/D converter, power circuit is that civil power is divided into two groups after the transformer step-down, one group through rectification, filtering, connect electric light source after the voltage stabilizing, another group is through rectification, filtering, be divided into two-way after the voltage stabilizing, one the tunnel connects the partial pressure type zeroing circuit of being made up of resistance and potentiometer, the high input end of the output termination A/D converter of zeroing circuit, another road is a signal amplifier, and A/D converter and nixie display provide forward bias.
The quality of lubrication oil analyser of being made by above-mentioned design has following advantage: 1, the oil sample thickness that forms with light transmission piece is far smaller than the oil sample thickness of setting with cuvette, has improved the light transmission of detection light source, has improved measuring accuracy; 2, with light transmission piece respectively to sample oil with in the method for doing transmittance detection comparative analysis with oil to be measured, realized quality testing, the sensing range of the analyser that has enlarged to the middle-and-high-ranking lubricating oil that is added with property-modifying additive.The utility model can be used for the analyzing and testing of quality of lubrication oil such as the vehicles such as vehicle, boats and ships and mechanical industry.
