Description
Technical field
Densitometer weighing method pick-up unit of the present utility model belongs to the metering detection range.
Background technology
At present the densitometric detection method of glass system is mainly used direct comparison method, is that standard density meter and tested densitometer are placed in the density solution that configures, and the method by direct comparison obtains tested densitometric modified value, owing to density less than 650kg/m
3Strong, the less stable of density solution evaporation, and greater than 1800kg/m
3The difficult configuration of density solution, so this method mainly is applicable to density range at 650kg/m
3～1800kg/m
3Between densitometer detect, surpass this scope then be difficult to carry out.The patent No. is 201020601110.0, and denomination of invention is the utility model patent of " petroleum densitmeter calibrating installation ", has following defective:
1. use the height of vacuum pump control liquid level, because the liquid or the air influence that exist in the pump make that the level control (LC) accuracy is low, when pump starts, can the stability of liquid level be impacted, densitometer is rocked greatly.
2. when needs are adjusted the liquid level height, the liquid of constant temperature can flow into main graduated cylinder or auxiliary graduated cylinder again by vacuum pump, when liquid will certainly produce temperature fluctuation the process of flowing in pump, and the residual liquid in the pump also can influence temperature in the main graduated cylinder, and it is inhomogeneous to produce temperature.
3. when needing to adjust the height of liquid level, by opening or close the mode of vacuum pump, on one side the people need observe liquid level, Yi Bian operated vacuum pumps, complicated operation can be brought artificial malobservation into.
Along with the development of Xinjiang petroleum economics, oil measurement is more and more important, presses for a kind of less than 650kg/m
3Greater than 1800kg/m
3The densitometer pick-up unit.
Summary of the invention
The purpose of this utility model be to provide a kind of can be to less than 650kg/m
3With greater than 1800kg/m
3The isolated plant that detects of densitometer, its control mode is various, and is easy and simple to handle, but the data acquisition and processing (DAP) robotization is finished.
The purpose of this utility model is achieved in that densitometer weighing method pick-up unit is made up of constant temperature, lifting, control system three parts, be equiped with electric cabinet at framework table, be laid with Programmable Logic Controller, man-machine interface touch-screen, stepper motor driver and power supply in it, storing has the hoistable platform of the stepper motor of attaching troops to a unit, put electronic balance on this platform, electronic balance is connected with computer circuitry.Under framework table, put constant temperature water bath, put solution tank in the groove, difference splendid attire water and density solution in two grooves.Electronic balance is hung tested densitometer in the density solution of solution tank by messenger wire, and putting simultaneously in this groove has the standard density meter.Programmable Logic Controller is linked to each other with man-machine interface touch-screen circuit with stepper motor driver respectively.
This device drives the hoistable platform displacement because adopting the Controlled by Programmable Controller stepper motor by it, the moving high electronic balance upper and lower displacement of accuracy of holder, thus realized that tested densitometric multiple spot detects.By control step motor stride value, make the least displacement amount of hoistable platform can reach 5 microns, can make tested densitometric calibrating graticule accurately concordant with liquid level, thereby realize detecting more steadily, accurately.In this device solution tank the density solution level consistently, temperature constant, temperature evenly can be to less than 650kg/m
3With greater than 1800kg/m
3Densitometer precisely detect, easy and simple to handle, but the data acquisition and processing (DAP) robotization is finished.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is densitometer weighing method pick-up unit structural representation;
Fig. 2 is touch-screen, Programmable Logic Controller, stepper motor driver, stepper motor annexation synoptic diagram.
Legend: 1, computing machine, 2, electronic balance, 3, hoistable platform, 4, messenger wire, 5, tested densitometer, 6, the standard density meter, 7, constant temperature water bath, 8, solution tank, 9, framework, 10, man-machine interface touch-screen, 11, Programmable Logic Controller, 12, stepper motor driver, 13, stepper motor.
Embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: shown in Fig. 1-2, densitometer weighing method pick-up unit is by constant temperature, lifting, control system three parts are formed, table top at quadra 9 is equiped with electric cabinet, be laid with S7-200 PLC(CPU224xp in it) type Siemens Programmable Logic Controller 11, man-machine interface touch-screen 10, DM542A type stepper motor driver 12 and power supply, storing has ZXV (050-400) the MA01 type hoistable platform 3 of the stepper motor 13 of attaching troops to a unit, put AL204-IC type electronic balance 2 on this platform, the RS232 serial communication port of this balance is connected by Serial Port Line with serial ports of computers.Under framework 9 table tops, put the transparent RTS-5A type constant temperature water bath 7 in four sides, put solution tank 8 in the groove, splendid attire water in the constant temperature water bath 7, splendid attire alcohol in the solution tank 8.The winding device of electronic balance 2 is hung tested densitometer 5 in the density solution of solution tank 8 by messenger wire 4.Stepper motor driver 12 is linked to each other with A+, A-, B+, the B-terminal of stepper motor 13.Programmable Logic Controller 11 is linked to each other with stepper motor driver 12, man-machine interface touch-screen 10 circuits respectively.
During detection, standard density meter 6 is immersed in the density solution of solution tank 8, measure the density value of this solution, the solution stirring apparatus that is carried by constant temperature water bath 7 guarantees that trough inner water body temperature field is even, and the split type refrigeration system that this groove carries stirs a temperature recycle design in addition on the motor of Cai Yonging, guarantee constant temperature water bath 7 frictions, keep water body constant temperature, thereby make density solution constant temperature in the solution tank 8, realized that solution density is stable.General densitometric adjacent two scale division distances are all identical, adjust the height of tested densitometer 5 when needs, when making its next calibrating graticule concordant with liquid level, configure the shift length of hoistable platform 3 in advance at touch-screen 10, this distance is the next one calibrating graticule of tested densitometer 5 and the distance of liquid level.Under the situation of automatic mode, behind the click start button, stepper motor 13 drives hoistable platforms 3 displacements, and when this platform 3 arrived the shift length of setting, stepper motor 13 stopped automatically, and it is namely concordant with liquid level that the next one of tested densitometer 5 is examined and determine graticule at this moment.The collection of electronic balance 2 weighing values, calculating and raw readings generate and finish automatically by computing machine 1.
