In figure: 1-Test Host, 2-coupon pallet, 3-temperature sensor I, 4-touch-screen, 5-temperature sensor II.
Embodiment
Below in conjunction with Figure of description, the invention will be further described:
As shown in Figure 1, a kind of pipe thermal conductivity tester, comprise Test Host 1, described Test Host 1 arranges touch-screen 4, touch-screen 4 operates for carrying out when heat conductivility is tested and controls, touch-screen 4 is provided with on-test button, off-test button, arranges button, refresh button, history curve button, statistical conversion button, real-time status button, system illustrate the buttons such as button, convenient operation, described Test Host 1 top is equipped with a pair coupon pallet 2, for placing sample tubing, Test Host 1 is gone back set temperature sensor I 3 and temperature sensor II 5, power module and control module for providing power supply is set in Test Host 1, described temperature sensor I 3 is signal with temperature sensor II 5 and control module and is connected, wherein temperature sensor I 3 is connected with sample tubing, temperature sensor II 5 is placed in the surrounding environment of sample tubing, described sample tubing one end sealing, other end termination is equipped with internal thread, described temperature sensor I 3 is equipped with the externally threaded sealing plug of band, sealing plug and sample tubing termination are by screw thread compact siro spinning technology, sample tubing is built with zero degree medium, this zero degree medium is the salt solution of 0 DEG C, also can be other similar media, this temperature sensor I 3 is for the temperature of tested media, due to the heat transfer effect of temperature, heat trnasfer can be carried out by sample tubing between zero degree medium and environment in sample tubing, until internal and external temperature is identical, time length needed for temperature variation, judge the heat conductivility good job of this sample tubing,
By adopting pipe thermal conductivity tester of the present invention to test tubing heat conductivility, concrete grammar comprises the steps:
1) Test Host 1 is placed in isoperibol, is generally 20-25 DEG C, be energized to Test Host 1, treat that touch-screen 4 is started shooting complete, enter operation interface, touch experiment stop button, confirm normal halted state;
2) by zero degree medium, be generally salt solution or other media of 0 DEG C, pour in the sample tubing that sealed one end, temperature sensor I 3 to be inserted in sample tubing pipe and screwing hermetic, again sample tubing is placed on the coupon pallet 2 of Test Host 1, temperature sensor II 5 to be put in below coupon pallet 2 and knocking in air, input the information of the title of this sample tubing, specification, numbering, checker at touch-screen 4 Interface Options frame respectively, and preserve;
3) on touch-screen 4 interface, on-test button is pressed, because medium temperature is different from environment temperature, according to heat transfer effect, in medium, temperature can slowly rise, last identical with environment temperature, temperature sensor I 3 and temperature sensor II 5 start temperature variation and the variation of ambient temperature of measuring zero degree medium in sample tubing respectively, record two groups of temperature datas and display two temperature curves, and display record time on-test, identical with environment temperature in the temperature of zero degree medium, article two, when temperature curve overlaps, press off-test button and terminate test, the display record off-test time, obtain simultaneously and show the total time number of test,
4) test period when two temperature curves obtained by step 3) overlap, judge the heat conductivility of tubing, the heat conductivility of time longer explanation sample tubing is poor, its good heat conductivity of time short explanation.
In process of the test, can also proceed as follows, press on-test button, on-test, also records data and display curve, display record time on-test, presses off-test button, the display record off-test time, obtain simultaneously and show the total time number of test; Press and arrange button, the display data query time period arranges interface, can arrange the time period of the data that will inquire about; By refresh button, show the data of the time period arranged; Press history curve button, the temperature curve of time period has been established in display; By arbitrfary point on curve, the time of display arbitrfary point, pipe interior temperature, environment temperature; Press statistical conversion button, can by the statistical conversion that inquires to USB flash disk; Press real-time status button, get back to operation display interface; The system of pressing illustrates button, and display operates, arranges teachings book.
The tester of designed, designed of the present invention, it is made up of two temperature sensors, the Test Host of band touch-screen, coupon pallet, and its structure is simple, easy to operate, easy to maintenance, and production cost is low, is suitable for suitability for industrialized production application; By the heat conductivility of this tester test sample tubing, the problem that the plastic pipe product heat conductivility solving existence at present cannot be tested, make that enterprise can facilitate in process of production, science, intuitively testing product performance, technique has filled up domestic blank, is suitable for applying.
