    F-TQG15 non-contact train shaft end photoelectric speed sensor

    The F-TQG15 non-contact train-side photoelectric speed sensor developed by our company mainly solves the two major difficulties inherent in the current speed sensors installed on domestic railways.

    The universal use of non-contact transmission mechanism can solve the disadvantages of frequent mechanical failure caused by universal coupling transmission mechanism. The non-contact transmission mechanism is not affected by the huge inertia of the wheel pair, the shaft load is small, and the possibility of mechanical failure is: Zero, and can greatly increase the speed of the sensor.

    The use of a fully sealed structure overcomes the problem of light source pollution. Due to the use of a non-contact transmission mechanism, the sensor part can be completely sealed. No matter the pollution source in the inner cavity of the axle box or the external pollution source will not be able to penetrate, its reliability is greatly improved.

The exhaust turbocharger on the diesel engine of a diesel locomotive is a rotating mechanical part that works under high temperature and high speed conditions. The turbocharger failure is an inertia failure of the domestically produced high-power diesel locomotive. After the breakdown of the turbocharger, it was found that most of the rotor shaft strains, bearing burnouts, compressor impeller scavenging, and turbines were found. A large amount of coke deposits at the end and cracks in the tongue and groove of the turbine disk, etc., but in serious cases, the sintering of the rotor shaft cannot be disintegrated, and even the supercharger is severely damaged. It is difficult to analyze which parts are the source of the failure. However, the existing static detection tools cannot dynamically and accurately analyze and diagnose the hidden troubles and fault locations of the turbocharger, so it is difficult to formulate very effective preventive measures.
