Abstract

The utility model relates to a vision all automatic motion viscosity detector for testing motion viscosity for petroleum products and other liquid. Computers and relevant software are adopted to be connected with a programmable logic controller (PLC) and control the operation of instruments. The artificiality inspections are replaced by cameras. The current position of test samples is shot and input into computers synchronously. The viscosity number of test samples are automatically calculated and stored in computers. A U-shaped curved Pinkevich capillary viscometer is replaced by the vertical capillary viscometer. Therefore, compared with the existing motion viscosity detectors, the vision all automatic motion viscosity detector has high automaticity and convenient operation, and is easy to test comparatively.

Description

The full-automatic kinematic viscosity analyzer of a kind of vision
One, technical field:
The utility model relates to the full-automatic kinematic viscosity analyzer of a kind of vision.
Two, background technology:
Departments such as petrochemical complex usually carry out the kinematic viscosity test to oil product and other fluent meterials, all will use viscosity determinator.The existing viscosity determinator overwhelming majority is manual conventional instrument, minority manufacturer has developed the robot that utilizes photoelectricity or thermal sensing element test samples mobility status, conventional instrument is got from the sample dress, and kapillary is corrected to a series of processes such as sample testing, cleaning and all needs manual operations.In the test process of viscosity number, the operator will hand stopwatch, observes the sample mobility status, starts repeatedly, stops stopwatch, and writing time, result of calculation so just makes very inconvenience of operation.Moreover because everyone observing response ability is different, even same individual also changes in the observation of different time, varying environment, the inaccurate situation of test result will appear like this.When cleaning instrument, operating personnel contact organic solvent for a long time, and are also influential to health of human body.
Automatic detection instrument with the photovalve manufacturing, because photovalve and annex thereof are installed in the outer wall of viscosity meter, hidden viscosity meter expansion and timing groove fully, be unfavorable for paired observation test, the viscosity meter that this instrument adopts mostly and standard-required be not inconsistent.
Automatic detection instrument with the thermal sensing element manufacturing, its thermal sensing element is installed in Pin Shi viscosity meter inwall, though energy is the test samples flowing time accurately, but because these elements must be immersed in the thermostatic bath that iknsulating liquid is a medium, after a period of time, oxidation can take place insulating medium makes and darkens, if untimely replacing can cause element testing malfunctioning, then operating cost can be very big often to change medium.
In addition, the Pin Shi capillary viscosimeter that existing instrument is adopted is two ends length thickness asymmetric " U " type glass tube, a long and thin upper lateral part has two expansions, the graticule place of promptly pick up counting " a " point and termination timing " b " point, and the bottom is a kapillary.Owing to form fluid column when liquid passes through " U " type kapillary, offset the gravity P right side that its right-hand member down moves, cause the viscosity number generation error of same sample, the more important thing is that self-reacting device adopts this viscosity meter to clean quite difficulty.
Three, summary of the invention:
The utility model is in order to overcome the drawback of existing analyzer and capillary viscosimeter, a kind of full-automatic kinematic viscosity analyzer of vision that meets national standard, automaticity height, easy operating, is convenient to contrast test is provided, and supporting with it vertical capillary viscosimeter.
The utility model is made up of computing machine and related software, photoelectric detection system, sample bench, jacking gear, sample cup, vacuum pump, oil pumping solenoid valve, thermostatic bath, emptying solenoid valve, vertical capillary viscosimeter, camera, micro pump, solenoid purge valve, cleaning agent tank, air pump, air blowing solenoid valve.It is characterized in that being equipped with in the thermostatic bath a plurality of vertical capillary viscosimeters, the relative set internal diameter is respectively 0.4,0.6 as required, and 0.8,1.0,1.2,1.5,2.0,2.5,3.0,3.5,4.0,5.0, the viscosity meter of 6.0mm, the middle part of viscosity meter is manufactured with the different expansion of a plurality of volumes.Camera places a side of thermostatic bath, and the sample mobility status in the aligned perpendicular capillary viscosimeter carries out image acquisition, and imports computing machine immediately, draws the test duration, calculates the kinematic viscosity value.
The beneficial effects of the utility model are:
1, can realize full-automatic selection, temperature control, viscosity test, cleaning and dry capillary viscosimeter.
2, improve the precision of sample testing time, reached 0.01 second.
3, avoided photovalve and thermal sensing element to detect caused drawback.
4, vertical capillary viscosimeter test expansion can increase N, has not only avoided the influence of fluid column pressure reduction to it effectively, and once can detect a plurality of samples, realizes the effect of a quite a lot of viscosity meter.
5, available tap water greatly reduces instrument operating cost as thermostatic medium.
6, can test Dark-colored Oil.
