Abstract
The utility model discloses a temperature and rotor speed monitoring system for a high speed refrigerating large capacity centrifuger. The temperature and rotor speed monitoring system for the high speed refrigerating large capacity centrifuger comprises a temperature sensor arranged in a centrifuger body, a rotate speed sensor arranged at a rotor and a digital display tube arranged on the shell of the body, as well as a central processor, an alternating current motor driver and an electromagnetic valve. The temperature sensor is connected with the central processor through a temperature signal processing module, the rotate speed sensor is connected with the central processor through a rotate speed signal processing module, the central processor is connected with the digital display tube, the electromagnetic valve and the alternating current motor driver, and the alternating current motor driver is connected with an alternating current variable frequency motor. According to the temperature and rotor speed monitoring system for the high speed refrigerating large capacity centrifuger provided by the utility model, the sensor can detect the temperature and rotate speed quickly and accurately, the central processor can effectively process the temperature and rotate speed information, and the 0.8-inch high brightness digital display tube can intuitively and observably remind operators.
Description
Technical field
The utility model relates to freezing big capacity centrifuge temperature of a kind of high speed and rotor speed monitoring system.
Background technology
Just as most plant equipment, centrifuge all has requirement definitely in when work to temperature and rotor speed, when temperature and rotating speed surpassed centrifuge on prescribe a time limit, centrifuge just might break down.Be out of order for fear of machine, real-time monitoring system is essential.Yet some present centrifuges are not to adopt sensitive temperature sensor thermometric; Rotor speed then adopts methods such as mechanical location switch, supersonic sounding to detect; Above-mentioned test mode is slow in reacting, and is also inaccurate, can not make a response to overtemperature and hypervelocity in time.
The utility model content
The purpose of the utility model is to solve the deficiency of prior art, but a kind of quick temperature measurement is provided and tests the speed, can Intelligent treatment the freezing big capacity centrifuge temperature of high speed and the rotor speed monitoring system of information.
The purpose of the utility model realizes through following technical scheme: freezing big capacity centrifuge temperature of high speed and rotor speed monitoring system; It comprises the temperature sensor that is arranged in the centrifuge body, is arranged on the speed probe at rotor place and is arranged on the digital display tube on the body fuselage; And central processing unit, alternating current motor driver and magnetic valve; Temperature sensor is connected with central processing unit through the processes temperature signal module; Speed probe is connected with central processing unit through the tach signal processing module, and central processing unit is connected with digital display tube, magnetic valve and alternating current motor driver, and the alternating current motor driver is connected with alternating-current variable frequency motor.
The described digital display tube of the utility model adopts 0.8 cun high brightness charactron.
The beneficial effect of the utility model is: sensor can detect temperature and speed conditions fast and accurately, and central processing unit is treatment temperature and rotary speed information effectively, and 0.8 cun digital display tube of high brightness can more observably be reminded operating personnel.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described: be as shown in Figure 1; Freezing big capacity centrifuge temperature of high speed and rotor speed monitoring system; It comprises the temperature sensor that is arranged in the centrifuge body, is arranged on the speed probe at rotor place and is arranged on the digital display tube on the body fuselage; And central processing unit, alternating current motor driver and magnetic valve; Temperature sensor is connected with central processing unit through the processes temperature signal module; Speed probe is connected with central processing unit through the tach signal processing module, and central processing unit is connected with digital display tube, magnetic valve and alternating current motor driver, and the alternating current motor driver is connected with alternating-current variable frequency motor; Described digital display tube adopts 0.8 cun high brightness charactron.
During use; When temperature or rotor speed surpass the upper safety limit value in detecting body; Central processing unit just cuts out alternating-current variable frequency motor through the alternating current motor driver, makes centrifuge quit work, and central processing unit is also controlled the closed electromagnetic valve feed tube; The charactron of central processing unit control simultaneously display digit 2 or 6 representes that this shutdown is because organism temperature or rotor speed have surpassed the upper safety limit value.
