PU220 Series Solenoid Valve

According to the regulations of safety regulations for small coal muffler mine, the mine explosion-proof trackless rubber car must be equipped with mine explosion-proof monitoring system to effectively monitor the various indicators of the trackless rubber car. Once it exceeds the standard, it will immediately make a reaction action, which requires sound and light alarm, and stop operation as required, so as to ensure the safe use of explosion-proof trackless rubber car. A new generation of in vivo tumor spectrometers can be used for noninvasive detection of living tumors. It has the advantages of small structure, moderate price, easy to use and convenient for early diagnosis of cancer. The device mainly includes the connection of light source and optical fiber system, the processing of optical fiber transmitter, the realization of in vivo detection transmission system, and the software and hardware facilities of spectrum acquisition and signal processing for tumor in vivo spectral detection. Compared with pathological section analysis and endoscopic observation analysis, the spectral detection of tissue samples in vitro is realized, and the excellent muffler sign of tissue is identified, so that doctors can fully rely on this equipment for diagnosis. In the motor control technology, the application of single chip microcomputer replaces the traditional analog PWM control, which makes the control more accurate and flexible, and adds various display functions, such as speed, mileage, intensity, etc. with appropriate sensors, the closed-loop control and synchronization can be realized.
