The load sensor is used to detect the change of diesel engine load and convert it into DC voltage output in proportion. The speed control unit is the core of the electronic governor, and the transmission of the self-speed sensor and the load sensor is accepted. After converting the voltage signal to the DC voltage, it is compared with the speed constant voltage.

The comparative comprehensive task is completed by the digital calculation in the microcomputer. Then the digital integrated signal is converted to the analog signal through the DA converter and then transferred to the electro-hydraulic servo valve. Obviously, in steady state, the output of the microcomputer in this way is zero.

However, the speed governor of the external users is constantly changing, that is, the M resistance is constantly changing, so the steam intake of the steam turbine must be changed accordingly to ensure the resistance of the M steam. Otherwise, the speed of the turbine will vary greatly with the external load. When the external load increases, the speed will decrease and the external load will decrease..

Well, let's talk about the speed limit control of these countries. Although it's really cool to drive, there's no need to expect too much. There's a good name for the law enforcement team. The car may cause the safety accidents to occur when the speed limiting device for vehicles is broken, the brake failure or the power shortage, and so on, which may lead to the danger of speeding and even falling in the car. The function of the speed limiter chip is to stop the car and prevent the passengers and equipment from being hurt in the above cases, thus avoiding the occurrence of safety accidents, so the vehicle speed limiter system is an extremely important part of the elevator's safe operation. In general, the speed limiter must carry out the type test before going out of the factory.

What is the working principle of the speed limiter and the safety tong? Speed limiter and safety tongs are very important mechanical safety devices. The speed limiter is connected to the safety rod on the two sides of the car by a wire rope. In order to ensure the speed and accuracy of the speed limiter, a speed limiter is installed in the bottom hole of the well.
