Background technology
Employed in the market rotary viscosity measuring instrument is when test testing liquid viscosity; All needing in advance liquid to be heated to assigned temperature measures then at once; In such measuring method; Be accomplished to from heating and begin to measure, the temperature of testing liquid can change, and can have temperature deviation.Especially drawing temperature when needs, needs heat testing liquid repeatedly during the viscosity change curve from 30 ℃ to 60 ℃, time-consuming effort again, and temperature also has deviation, thus the accuracy that causes measuring is relatively poor.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of can be constant, the stable alternating temperature viscosity measurement system of testing liquid temperature in the control survey process continuously.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of stable alternating temperature viscosity measurement system; Comprise: testing liquid is deposited vessel; Said testing liquid is deposited vessel inside and is provided with and is used for heating element and temperature sensor that testing liquid is directly heated; This system also comprises the output signal of accepting temperature sensor, and according to the switching of this signal controlling heating element electricity, with the temperature stabilization of testing liquid in the temperature controller of setting value.
Through such design, the temperature of temperature sensor senses testing liquid also feeds back to temperature controller, and temperature controller is controlled as follows: when this feedback temperature is lower than design temperature, heat, promptly switch on to heating element; And when this feedback temperature is higher than this design temperature, heating element outage, entering keeping warm mode, thus the temperature stabilization that can make testing liquid promptly can be realized the constant control of testing liquid temperature in desired set value.And through heating element is heated testing liquid directly, constantly; Then can obtain continuous temperature change value; Under this condition, testing liquid is measured continuously; Then can obtain continuous viscograph, promptly can realize testing liquid temperature in the control survey process continuously corresponding to continuous transformation temperature.
Said heating element be in the shape of a spiral shape from the bottom around resistance wire to the top.
Annular spiral arrange to make to the heating of testing liquid sooner, more even.
Said testing liquid is deposited the vessel outside and also is provided with heat-insulation layer.
The setting of heat-insulation layer, the distributing to external world of reducing the heat of testing liquid obtains temperature control consistently more easily.
Said heat-insulation layer is that thickness is the asbestos of 10mm.
Said temperature controller is the temperature controller of closed-loop control.
The utility model compared with prior art has following advantage and beneficial effect:
The stable alternating temperature viscosity measurement system of the utility model; Be provided with and be used for heating element and temperature sensor that testing liquid is directly heated through deposit vessel inside at testing liquid; Native system also comprises temperature controller simultaneously; Temperature controller is accepted the output signal of temperature sensor, and according to the switching of this signal controlling heating element electricity, with the temperature stabilization of testing liquid in setting value.The situation that temperature controller is compared with design temperature according to the temperature that temperature sensor fed back, the break-make of controlling heating element is electric, thus the temperature stabilization that can make testing liquid promptly can be realized the constant control of testing liquid temperature in desired set value.And, then can realize the temperature of testing liquid in the control survey process continuously through heating element is directly heated testing liquid continuously.
Description of drawings
Fig. 1 is the structural representation of the stable alternating temperature viscosity measurement system of the utility model.
Embodiment
Below, describe with reference to the embodiment of accompanying drawing the utility model.
As shown in Figure 1; The stable alternating temperature viscosity measurement system of the utility model comprises: testing liquid is deposited vessel 1; Depositing vessel 1 inside at testing liquid is provided with and is used for testing liquid (shown in the cross dash area of figure) heating element 2 and the temperature sensor 3 that directly heat; Testing liquid is deposited vessel 1 external packets and is wrapped with heat-insulation layer 5, and preferred thickness is the asbestos layer of 10mm here.Native system also comprises temperature controller 4; The ST-801S-96 temperature controller of preferred here closed-loop control; Its input end is connected with temperature sensor 3, and output terminal is connected with heating element 2, here; Temperature controller 4 is accepted the temperature signal of the feedback of temperature sensor 3; And according to the switching of this signal controlling heating element 2 electricity, promptly temperature controller 4 through following control procedure with the testing liquid temperature stabilization in setting value, when the feedback temperature of the output of temperature sensor 3 is lower than design temperature, heating element switched on and heats; And when this feedback temperature was greater than or equal to this design temperature, to heating element outage, entering keeping warm mode, thereby the temperature stabilization that can make testing liquid promptly can be realized the testing liquid accuracy control over temperature in desired set value.
As shown in the figure, preferred heating element is for to deposit vessel 1 inwall along testing liquid, and to the spiral resistance wire of layout of peristome annular, its material is Cr20Ni80 from the bottom.
In the concrete measuring process; Can be cooled at first testing liquid put into testing liquid and deposit vessel 1 below the minimum measurement temperature of liquid to be measured 2 energisings of temperature controller 4 control heating elements earlier to indoor temperature through air-conditioning; Directly testing liquid is heated; After it arrives predetermined measurement temperature, the rotating rod 6 of rotary viscosity tester is put into testing liquid, carry out the measurement of viscosity; In measuring process; The testing liquid temperature variation that the factors such as heat interchange of carrying out owing to testing liquid and surrounding environment cause is when (departing from setting value); The situation that temperature controller can be compared with design temperature according to the actual temperature that temperature sensor fed back; Come the switching electricity of corresponding control heating element, thereby the temperature stabilization that can make testing liquid is in desired set value.In addition, can also heat to be measured liquid continuously, thereby measure the viscosity change curve under the continuous temperature change condition, promptly can draw temperature and viscograph continuously according to the needs of actual measurement.
To sum up; Native system can the electronic settings temperature; Through resistance wire testing liquid is directly heated, adopt asbestos to be incubated, the stirring theory through rotational viscosimeter makes the testing liquid temperature even; With temperature sensor senses Temperature Feedback numerical value temperature controller, temperature controller is controlled heating system according to value of feedback.
Certainly the stable alternating temperature viscosity measurement system of the utility model also can do like down conversion: promptly temperature controller also can be selected other model; The material of heat-insulation layer also can be selected other insulation material; Heating element also can be other form, for example can be straight rod, U-shaped rod etc., and its coiling mode and Material Selection also can be other.Such conversion all drops within the protection domain of the utility model.
