The utility model is characterized in that the test device also comprises a test sensor which is combined on the side surface of the base seat; the test sensor is formed in a mode that a peripheral circuit of the test sensor is composed of a sensor circuit controlled by an SCM circuit, a linear array CCD chip, an optical taking lens, an inverting amplifier, a dot array liquid crystal display, a keyboard, a storage, etc. When used for the dynamic test of lubricating grease points at dripping points of lubricating grease, the utility model has the advantages of high test precision, good repeatability and good reproducibility, and the automatic dynamic test of lubricating grease points at dripping points of lubricating grease is realized.
Description
Technical field
The utility model relates to the grease checkout equipment, particularly a kind of lubricant grease dropping point dynamic measuring instrument that is used for carrying out when lubricant grease forms the liquid oil droplet at a certain temperature detection of dynamic.
Technical background
Measuring method to the lubricant grease dropping point is to measure according to State Standard of the People's Republic of China GB4929-85 " lubricant grease dropping point determination method " at present, its method is to adopt easy device to heat, when oozing, grease, mainly has following shortcoming by eye manual observation:
Require experimenter's notice high concentration, otherwise can miss the moment that grease oozes, cause measuring error; The manual measurement degree of accuracy is poor, oozes when observing grease, writes down two temperature values again, can cause the temporal error of temperature survey, thereby influence measuring accuracy; The error of manual operation is big, and manual observation, record and operator have direct relation, even therefore to same instrument, and same sample, the error that standard allows reaches 7 ℃, and this scope is very wide, also will exceed this error in the practical operation in some is measured; The chance that manually-operated makes mistakes is many, oozes observation at grease, and any one link of temperature record is made mistakes, and experiment this time just fails, so conventional efficient is very low; Existing instrument repeatability is poor, and in the different experiments chamber, reproducibility error reaches 13 ℃ by the different operating person.Existing instrument functions of use is poor, according to the testing crew reflection, uses existing equipment to need to be equipped with two to three operating personnel at least, observes oil droplet and record temperature respectively.
In view of the prior art above shortcomings, the utility model provides a kind of sensor technology that utilizes to be lubricated the novel lubricating grease dropping point dynamic measuring instrument that drip of grease point dynamically detects, writes down testing result.
Summary of the invention
The technical scheme that the utility model is taked for achieving the above object is: detector comprises pedestal, magnetic agitating heating device, stirring rod, stauffer cup, test tube, thermopair; It is characterized in that: described detector also comprises a detecting sensor with the aggregate erection of pedestal side.Sensor is by the sensor circuit of single chip circuit control and comprise that line array CCD chip, optics pick-up lens, sign-changing amplifier, lattice lcd display, keyboard and storer etc. form its peripheral circuit and form; CCD chip and optics pick-up lens are fixed on the sidepiece of lubricant grease dropping point detection of dynamic sensor, and CCD chip and optics pick-up lens centrally aligned stauffer cup end opening should be focus point with the stauffer cup end opening.
Compared with prior art, adopting this method that lubricant grease dropping point oil droplet is carried out detection of dynamic has the following advantages: realized the dynamic auto detection of lubricant grease dropping point oil droplet; The accuracy of detection height; Good reproducibility; Repeatability is good, and keyboard and LCD is mutual in the employing microprocessor, can set surveyed area flexibly, adapts to the different oil droplet shapes of different oils lipid species.
