Abstract
The utility model discloses a survey viscosity measurement appearance of spheroid at the intraductal speed that falls with infrared photoelectric sensor, when the spheroid through upper and lower probing point, infrared photoelectric sensor sends the detection signal respectively to trigger automatic counter, make it begin to count or stop counting, the counter with the pulse number input speed/viscosity converter of record between two standard pulses, again through latching decoding drive arrangement and display device automatic demonstration viscosity number.
The device can directly display the viscosity value, thereby being capable of continuously measuring the viscosity of a large batch of oil samples, being convenient for automatically monitoring the operation condition of the equipment and improving the measurement precision.
Description
The utility model relates to a kind of oil viscosity surveying instrument, relates in particular to a kind of falling ball viscometer.According to statistics, at present existing more than 200 kind of viscosity meter can be divided into by principle: as the rotary viscosimeter of tubule viscosity meter of your moral (Ostwald) viscosity meter of Oswald, Wu Bieluote (Ubbelohole) viscosity meter, Saybolt (Saybolt) viscosity meter, Redwood (Redwood) viscosity meter, Engler (Engler) viscosity meter, Ford cup (Ford Cup) viscosity meter, Zan En (Zahn) viscosity meter and so on and so on; Also have falling ball viscometer, vibration viscometer, ultrasonic viscometer or the like in addition.
Usually measure the kinematic viscosity of fluid more than the people with capillary viscosimeter, this viscosity meter is subjected to artificial factor bigger, thereby measuring error is big, and it is not high to measure viscosity, and is especially more restricted when measuring dark fluid or contaminated fluid.In addition, the kapillary made from glass is " U " shape, ruptures easily and be not easy to clean.When measuring the fluid of the unknown trade mark, often need test of many times to select suitable kapillary and just can measure qualified viscosity data, thereby increased the workload of measuring greatly, cause the very big waste of human and material resources.And the instrument volume is big, and specialized laboratories must be arranged, and can not directly measure at the scene.
British patent document GB1491865 discloses a kind of the utilization and has measured the falling ball viscometer that the speed of fall of bead in fluid measured fluid viscosity, it is made up of viscometer tube, the stainless steel ball that is loaded in the pipe, and inductive coil is equipped with in the upper and lower part that centers on the viscometer tube outer wall.During measurement, charge into testing liquid in the viscometer tube, when stainless steel ball induces first detectable signal during by the upper induction coil position, first display device demonstrates this signal, simultaneously time set picks up counting, and when stainless steel ball induces second detectable signal during by inductive coil position down, second display device demonstrates this signal, timing simultaneously stops, thereby can obtain the viscosity of fluid to be measured.But this device can not directly show the viscosity number of fluid to be measured, therefore is not easy to continuous coverage oil sample viscosity in enormous quantities, also is not easy to the equipment situation is monitored automatically.
Task of the present utility model is that a kind of device of measuring oil viscosity will be provided, this device can with the movement velocity of measured spheroid in tested fluid as calculated conversion equipment be directly changed into viscosity and show.
The device of finishing above-mentioned task comprises: an inclination (or vertical) is provided with and is filled with the container of fluid to be measured, be loaded on the spheroid in the container, the proportion of spheroid is measured spheroid for two and is tumbled (or free-falling) optical sensor (A, B) to the fixed position greater than the proportion of fluid to be measured.Reception is by the impulse controller of the detectable signal of optical sensor output, by the automatic counting circuit that full sized pules triggered and the speed/viscosity converter of impulse controller output, the decoding drive unit and the display device of the output signal of receiving converter.
Device described in the utility model can directly show viscosity number, thereby can continuous coverage oil sample viscosity in enormous quantities, is convenient to the equipment operation situation is monitored automatically, and has avoided the influence of human factor to measured value, has improved measurement viscosity.
Below in conjunction with accompanying drawing the utility model is described in detail, wherein:
Fig. 1 represents oil viscosity measuring instrument schematic diagram of the present utility model;
Fig. 2 is an oil viscosity measuring instrument block diagram of the present utility model;
Fig. 3 is an oil viscosity measuring instrument circuit diagram of the present utility model;
Referring to Fig. 1 and Fig. 2, at material such as glass by the oil resistant erosion, pack in the container 1 that plastics etc. are made etc. and to survey oil sample 2, the shape of said vesse can be right cylinder, rectangular parallelepiped or multiple edge body, put into spheroid 3 in the container 1, this spheroid is by the material such as the glass of oil resistant erosion, steel or other metal are made, the proportion of spheroid is greater than waiting proportion of surveying fluid, container lean is provided with, the big I of its longitudinal axis and horizontal angle α changes in 1 ° of-90 ° of scope, container upper end is covered by end cap 4, on tilt container, a certain position, bottom (sensing point) is equipped with two infrared photoelectric sensor (A respectively, B), when the last sensing point of spheroid 3 processes, infrared photoelectric sensor A exports first detectable signal, this signal is delivered to impulse controller 21, by the first full sized pules flip-flop number 22 of impulse controller 21 outputs, counter 22 begins counting.When spheroid 3 during through sensing point down, infrared photoelectric sensor B exports second detectable signal, and this signal is delivered to impulse controller 21, triggers counter 22 by second full sized pules of impulse controller 21 outputs, and counter 22 stops counting.Counter 22 triggers the calculating pulse with two full sized puless and latchs the speed of flowing to/viscosity converter 23, and through decoding drive unit 24, display device 25 shows viscosity number automatically again.Other slave part is a count pulse generator as 16 among Fig. 2, and 17 is modulation pulse generator, 18 expression power drive, and 19 expression synchronizing signals, 20 expression demodulations by filter, 15 expression shapings are amplified.
