Abstract
The utility model provides a closed medical centrifuge rotational speed measurement system which characterized in that: closed medical centrifuge rotational speed measurement system includes motor driver, test tube, pure water, tacho sensor, tachometry appearance, wherein: the pure water is placed in the in vitro, and motor driver drives the test tube and rotates, and tacho sensor fixes on the shell of medical centrifuge, and tacho sensor is connected with the tachometry appearance, the utility model discloses an advantage: do not change the original structure of medical centrifuge and survey the rotational speed of getting the medical centrifuge under normal operating condition, this system can make things convenient for, accurately measure the rotational speed to the measurement accuracy of rotational speed expects much, has stronger practicality and security.
Description
Technical field
The utility model relates to medical centrifuge tachometric survey field, particularly a kind of closed medical centrifuge speed measuring system.
Background technology
Medical centrifuge is the Special Equipment that the centrifugal force produced by High Rotation Speed is carried out quick separating to different factor in precipitation compounding substances, concentrates and purify, integrate machinery, electrically, the multidisciplinary scientific instrument such as biological chemistry, be widely used in the field such as health care, blood station (storehouse), pharmaceutical factory, biomedical engineering, animals and plants research.

This system have passed the checking of great many of experiments, demonstrates and all can meet measurement requirement in accuracy and robustness, well can be applied, therefore have important Social benefit and economic benefit in actual medical centrifuge tachometric survey.
Summary of the invention
The purpose of this utility model is the measurement in order to realize medical centrifuge rotating speed, and spy provides a kind of closed medical centrifuge speed measuring system.
The utility model provides a kind of closed medical centrifuge speed measuring system, it is characterized in that: described closed medical centrifuge speed measuring system comprises motor driver 1, test tube 2, pure water 3, tachogenerator 4, tachometer of measuring 5; Wherein: pure water 3 is positioned in test tube 2, motor driver 1 drives test tube 2 to rotate, and tachogenerator 4 is fixed on the shell of medical centrifuge, and tachogenerator 4 is connected with tachometer of measuring 5.
Further, described tachogenerator 4 is piezoelectric acceleration transducer, and described tachogenerator 4 is fixed on the shell of medical centrifuge by strong magnet.
Further, described tachometer of measuring 5 at least also comprises charactron and hummer, and described charactron shows the rotating speed of medical centrifuge in real time, and described hummer carries out alarm to the rotating speed of exception.
Advantage of the present utility model: do not change medical centrifuge original structure and measure the rotating speed of medical centrifuge in normal working conditions, this system can measure rotating speed easily and accurately, and the measuring accuracy of rotating speed requires high, has stronger practicality and security.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is a kind of closed medical centrifuge speed measuring system theory structure schematic diagram.
Embodiment
The utility model provides a kind of closed medical centrifuge speed measuring system, it is characterized in that: described closed medical centrifuge speed measuring system comprises motor driver 1, test tube 2, pure water 3, tachogenerator 4, tachometer of measuring 5; Wherein: pure water 3 is positioned in test tube 2, motor driver 1 drives test tube 2 to rotate, and tachogenerator 4 is fixed on the shell of medical centrifuge, and tachogenerator 4 is connected with tachometer of measuring 5.
Further, described tachogenerator 4 is piezoelectric acceleration transducer, and described tachogenerator 4 is fixed on the shell of medical centrifuge by strong magnet.
Further, described tachometer of measuring 5 at least also comprises charactron and hummer, and described charactron shows the rotating speed of medical centrifuge in real time, and described hummer carries out alarm to the rotating speed of exception.
Closed medical centrifuge speed measuring system measures the principle of work of rotating speed based on vibration acceleration sensor, pure water 3 is put in test tube 2, the quantity of general test tube is 2, symmetrical placement, strong vibrations are avoided to occur like this, the symmetrical test tube High Rotation Speed under the driving of motor 1 installed, tachogenerator 4 is fixed on medical centrifuge shell, test tube 2 with pure water 3 often rotates a circle generation two pulse signals, namely be actual speed by umber of pulse divided by 2, this actual speed signal is by amplifying, shaping and tracking filter are the pulse signal that can measure, the tachometer of measuring 5 ranging pulse signal period calculates the rotating speed of medical centrifuge, finally on charactron, show real-time rotate speed, if when occurring that the situation of rotary speed unstabilization or rotating speed arbitrarily fluctuate, hummer carries out alarm.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
