YD923SK series digital electronic speed control system is a kind of device which can control the speed of power machinery such as diesel engine, gasoline engine, gas engine and so on. Because 16-bit microprocessor is used as the main control chip, besides the control of speed, power and torque can be limited and controlled, especially for the control of smoke emission and surge of turbocharger during sudden load change of turbocharged diesel engine and the monitoring of unit working condition. Therefore, this device is not only a digital electronic governor, but also a real one. Engine control system. Considering the different needs of users, the products are divided into ordinary type and enhanced type at present. The ordinary type is based on enhanced type, which simplifies some functions of the control system. Its control accuracy and characteristics are no difference, can be all kinds of internal combustion engines to achieve full speed control, start and maximum oil limit in order to prevent rapid increase in starting speed and smoke.

 

 

 

2. product characteristics

 

The device is composed of a controller, an actuator, a speed sensor, a power supply, a control panel and a special connecting conductor. The actuator is mounted on the engine and connected to the engine oil control mechanism through the lever and spherical joint on the output shaft. The speed sensor is mounted on the engine shaft speed measuring device, such as the flywheel gear ring. The controller can be installed as far away as possible from the actuator, or it can be installed at the appropriate position of the engine through the shock absorber.

 

 

3. product specifications

The system is equipped with LZ series of different actuators, which can be suitable for medium and high speed diesel engines with control power of 300 ~ 8000KW and rated speed of 750 ~ 2300 rpm. The electronic control device uses 24V DC power supply, in addition to the enhanced DC24V power supply, DC110V.

 

Since the maximum angle of the output shaft of the actuator can reach 75 degrees, it is especially suitable for the power machinery with nonlinear throttle and power relationship, such as gasoline engine or gas engine, whose working fluid is regulated by butterfly valve.

The system adopts RS422 serial communication interface, so it is convenient to modify the control parameters and display the dynamic and static process online through computer or handheld terminal (the total length of communication cable is not more than 1200 meters).
