Description
The utility model relates to a kind of viscosity measurements device, and especially the automatic detection device of petroleum products kinematic viscosity belongs to the technology of instrument and meter field.
Kinematic viscosity is an important quality index of petroleum products, presses the GB/T265 standard, during the oil viscosity labor measurement, often adopts the Pin Shi glass capillary tube viscometer.Because the special construction that two balls chamber of Pin Shi viscosity meter links, liquid level photoelectric detecting method in the past can't utilize this viscosity meter to do automatic measurement.Therefore, the automatic kinematic viscosity instrument that the past makes all adopts special Ubbelohde viscometer or other viscosity meter to replace the Pin Shi viscosity meter.Adopt the specific viscosity meter, this is for the demarcation of viscometer constant, the regular evaluation in the viscosity meter use, and the replacings after viscosity meter damages etc. all bring many troubles.In addition, because the depth difference of oil product color to be measured, all there is certain problem in original photoelectricity liquid level checking method in sensitivity, reliability, aspect repeated.
In order to overcome the defective that prior art exists, the utility model provides a kind of common Pin Shi viscosity meter that utilizes, the kinematic viscosity automatic detection device with higher sensitivity, reliability.
The utility model is achieved through the following technical solutions: the utility model is by the Pin Shi viscosity meter, fixed mount, thermostatic bath, the photoelectricity liquid level detection system, microprocessor controller, formations such as testing result output unit, wherein the photoelectricity liquid level detection system comprises the photometer head that two fiber switchs are housed, light-emitting component and photoelectric apparatus also are housed in the photometer head, every fiber switch is furnished with pair of optical fibers, every pair of fibre-optic end links with light-emitting component and photoelectric apparatus respectively, two pairs of light transmitting fibers are separately fixed in optical fibre frame and the following optical fibre frame, two pairs of fibre-optic other ends are two pairs of optical fiber gauge heads, are closely attached on respectively on the Pin Shi viscosity meter glass tube outer wall, following level detection scale mark place.
For making testing result accurate, angle preferably is an angle of 90 degrees arrangement between every pair of fibre-optic two optical fiber gauge heads.The Pin Shi viscosity meter also has position regulator in the utility model, promptly going up optical fibre frame is loaded on the portable plate, on the fixed mount corresponding on the optical fibre frame place, fixed head is housed, between fixed head and the portable plate movable screw is housed, by adjusting movable screw, portable plate is moved forward and backward, so that optical fiber gauge head is closely attached on Pin Shi viscosity meter glass tube outer wall level detection scale mark place.
Because the utility model adopts common Pin Shi glass capillary tube viscometer, and has position regulator, can adapt to the different outside dimension of Pin Shi viscosity meter, this is for the demarcation of viscometer constant, regular evaluation in the viscosity meter use, the replacing after viscosity meter damages etc., all very convenient.Because angle is an angle of 90 degrees arrangement between every pair of optical fiber gauge head, just testing result is not subjected to the influence of different colours oil product liquid level, has eliminated the deviation and the mistake that cause because of oil product color difference and has surveyed.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural representation of Pin Shi viscosity meter in the utility model;
Accompanying drawing 2 is the utility model one-piece construction synoptic diagram;
Accompanying drawing 3 is Pin Shi viscosity meter scale mark (a, a b) synoptic diagram in the utility model;
Accompanying drawing 4 is that every pair of optical fiber gauge head angle is arranged synoptic diagram in the utility model;
Accompanying drawing 5 is put the adjusting gear structural representation for optical fiber chord position on the utility model.
As shown in Figure 1, on the upper bearing plate 2 of Pin Shi viscosity meter, photometer head 1 is housed, two fiber switchs are housed in the photometer head 1, be i.e. fiber switch 1 and fiber switch 2.Light-emitting component and photoelectric apparatus also are housed in the photometer head 1, every fiber switch is furnished with pair of optical fibers, every pair of fibre-optic end links with light-emitting component and photoelectric apparatus respectively, two pairs of light transmitting fibers are separately fixed in optical fibre frame 5 and the following optical fibre frame 6, two pairs of optical fiber gauge heads are respectively by last, following optical fibre frame is fixed and is close to Pin Shi viscosity meter glass tube outer wall level detection scale mark place, common Pin Shi viscosity meter glass tube outer wall all indicates, following scale mark, use a among Fig. 3, b represents on the Pin Shi viscosity meter, following scale mark, wherein scale mark a place is positioned at the place that links, the two ball chambers of Pin Shi viscosity meter glass capillary, and scale mark b place is positioned at below pair ball chambers.As shown in Figure 4, angle is that 90 degree are arranged (Fig. 4) between two optical fiber gauge heads, can make testing result not be subjected to the influence of oil sample color like this.Because glass capillary tube viscometer during fabrication, physical dimension has certain error, cause easily between optical fiber gauge head and the kapillary outer wall slit is arranged, so optical fibre frame 5 places on correspondence on the fixed mount, fixed head 3 is housed, link by movable screw 9 between the portable plate 8 of fixed head 3 and equipped upward optical fibre frame 5, by be connected and fixed movable screw 9 between plate 3 and the portable plate 8 of adjustment, the optical fiber chord position is put with profile to be done suitably to adjust, make optical fiber gauge head be close to glass capillary outer wall scale mark place, to improve detection sensitivity, also adapt to the needs of viscosity meter replacing simultaneously.
Be the course of work of the present utility model below: as shown in Figure 5, survey the fixed mount 7 of the Pin Shi viscosity meter 4 of oil sample being equipped with, link in the insertion high precision constant temperature bath and with negative pressure pump, microprocessor controller, printer.Behind the oil sample constant temperature 20 minutes, with upwards suction of oil sample, during through the b scale, fiber switch 2 detects signal, sends into microprocessor controller by microprocessor controller control negative pressure pump.Shading when liquid level arrives a, microprocessor controller is received signal, and negative pressure pump stops after 1 second of delaying time, and this moment, liquid level surpassed scale mark.After negative pressure pump stopped, liquid level began to descend, when dropping to a scale, and the work of microprocessor controller control timer, when liquid level was reduced to the b scale, timing stopped immediately automatically.Be exactly that oil product flows through the certain diameter time capillaceous at a certain temperature during this period of time.So repeat four times, average, remove maximum deviation, surplus three test periods are averaged again, multiply by viscometer constant, as a result printout.
