electric to mechanical speedometer
Electronic speedometers are more accurate and sensitive than mechanical ones, and have better readability and visibility. Especially when driving at night, the backlight design of the electronic speedometer allows the driver to see the speed data more clearly. The mechanical speedometer requires manual calibration, and is easily affected by factors such as ambient temperature and terrain, and is prone to errors. With the continuous development of science and technology, electronic display technology can fully meet the accuracy requirements of automobile speedometers, so the use of mechanical speedometers can only be regarded as a kind of nostalgia or pursuit of tradition. If you want to have a better driving experience and more accurate vehicle speed data, please choose an electronic car speedometer.
1. After the generator is started, it needs to adjust the speed to achieve a stable rated speed. Only by ensuring the stability of the generator speed can the output voltage and frequency be guaranteed.
2. Mechanical governor does not need power supply, only electronic governor needs power supply.
3. According to the requirements of SOLAS, if the emergency generator is equipped with an electronic governor, a set of independent battery packs shall be provided for the electronic governor, which is different from the starting battery of the emergency generator. Therefore, the emergency generator with electronic speed regulation needs to be equipped with two sets of battery packs. The principles of mechanical speed regulation and electronic speed regulation are actually very simple.
4. The speed of the generator changes with the size of the accelerator. Just like a car engine, the speed of the accelerator is high, and the speed is low. Therefore, whether it is mechanical speed regulation or electronic speed regulation, it is ultimately controlled by the generator throttle. Achieved. I have only come into contact with one kind of mechanical speed regulation, which is a device similar to a swing ball on the rotating shaft of the generator. Different rotating speeds will produce different centrifugal forces, just like the prayer wheel in the hands of lamas. The faster you shake, the bigger the angle of the two pendulum balls will be. The throttle of the generator can be adjusted by the angle of the pendulum balls. Electronic speed regulation is simpler, there is a speed sensor, and the servo motor is controlled to drive the rack according to the speed signal to control the throttle.
