The tester for the dropping point of lubricating grease has the advantages of capacity of automatically detecting the dropping point of lubricating grease, high automation degree and small errors of detection, no need for waiting of cooling of a heating device, and improved detection speed.
Description
Technical field
The present invention relates to a kind of dropping point tester of lubricating grease.
Background technology
Assay method to grease dropping point is according to standard GB/T 4929-85 at present《Grease dropping point determination method》It is measured, is heated using oil bath, grease oozes dependence eye-observation, be primarily present following shortcoming：Automaticity is not high, and manual operation takes, error is high, the shortcomings of manual measurement poor accuracy.
Content of the invention
The present invention is directed to the shortcoming that prior art exists, and provides that a kind of error is little, the grease dropping point detector of full automation detection.
The present invention employs the following technical solutions：
A kind of dropping point tester of lubricating grease, including the detection case above pedestal, pedestal and control cabinet.Power switch, display screen and control process unit are provided with control cabinet；A circular hole is opened in detection box top on pedestal，And in tapping equipped with a ring support，It is tied with electromagnetic heating coil outside ring support、A stainless steel fat cup is placed in ring support，Fat cup is held up and fixing by 3 level supports of ring support inside bottom，Thermocouple is fixed on the circular hole size identical stopper that an external diameter is opened with detection box top，By stopper, thermocouple is fixed in the perforate of detection box top，Thermocouple is made to insert in ring support，And stretch in fat cup，Put a beaker in the underface of ring support and fat cup，Casing at detection case side with fat cup bottom equal height is coated with one section of reflecting layer，It is provided with height regulating rod near another side box body of detection case，Reflex laser sensor is arranged on height regulating rod，Reflex laser sensor can be launched simultaneously and receive laser reflection signal，This reflex laser sensor is connected with control process unit，Electromagnetic heating coil on ring support and thermocouple are all connected with control process unit，Control process unit is connected with display screen.
Described control process unit is for controlling heating power and the speed of electromagnetic heating coil, the signal transmitting of control record reflex laser sensor and reception, record electric thermo-couple temperature, and processing data and transmitting to display screen.
Described display screen is touch, for showing and realizing function to set, can be with design temperature, and displays temperature, display reflex laser sensor test case and consult test record.
The internal wall of described detection case is respectively mounted thermal insulation layer.
Described stopper is metal or quality of rubber materials.
Setting height(from bottom) on height regulating rod for the reflex laser sensor is installed according to the height that GB GB4929-85 requires, and that is, reflex laser sensor and the support vertical range of the ring support bottom holding up fat cup are 19mm.The shape of fat cup and size also make according to the size that GB GB4929-85 requires.
Beaker is used for connecing the lubricating grease from fat cup drippage in test process, can save wash number.
The present invention passes through the presetting initial temperature of touching display screen, heating schedule, then by control process unit so that electromagnetic heating coil, thermocouple and reflex laser sensor are started working.In grease dropping point continuous mode, realize automatically determining.
It is an advantage of the current invention that：Hold preparation of greases and be separated with the beaker receiving oil droplet, convenient cleaning, automatic detection can be carried out to grease dropping point, the sensitivity of detection is high, error is little, because electromagnetic heating coil only plays heat effect to fat cup, as long as the fat cup finishing experiment carries out changing can be tested it is not necessary to wait the cooling of heater next time, improve detection speed.

Specific embodiment
Below in conjunction with accompanying drawing 1, the present invention is described in further detail.
A kind of dropping point tester of lubricating grease, is provided with power switch 4, display screen 6 and control process unit 5 including on pedestal 1, the detection case 3 of pedestal 1 top and control cabinet 2, control cabinet 2；A circular hole is opened in detection box top on pedestal，And in tapping equipped with a ring support 10，It is tied with electromagnetic heating coil 9 outside ring support 10、A stainless steel fat cup 11 is placed in ring support 10，Fat cup 11 is held up and fixed by 3 level support 16 of ring support 10 inside bottom，Thermocouple 7 is fixed on the circular hole size identical stopper 8 that an external diameter is opened with detection box top，By stopper 8, thermocouple 7 is fixed in the perforate of detection box top，Thermocouple 7 is made to insert in ring support 10，And go deep in fat cup 11，Put a beaker 15 in the underface of ring support 10 and fat cup 11，Casing at detection case 3 side with fat cup 11 bottom equal height is coated with one section of reflecting layer 12，It is provided with height regulating rod 14 near another side box body of detection case，Reflex laser sensor 13 is arranged on height regulating rod 14，Reflex laser sensor 13 can be launched simultaneously and receive laser reflection signal，This reflex laser sensor 13 is connected with control process unit 5，Electromagnetic heating coil 9 on ring support 10 and thermocouple 7 all connect with control process unit 5，Control process unit 5 and display screen 6 connect.
During test, with single-point or wire is become to drip working as the lubricating grease adding in thermal grease cup, because the laser that reflex laser sensor transmitting terminal is transmitted into reflecting layer is blocked, the receiving terminal of reflex laser sensor does not receive reflected signal or signal is significantly decayed, temperature when grease oozes under now control process unit record, stop heating, data storage by data display over the display.Experiment terminates, and takes out thermocouple, presss from both sides out fat cup with clip, is reentered into next fat cup and gets started next test.The lubricating grease receiving in beaker changes beaker when will overflow, or lubricating grease is outwelled reuses after cleaning.
