Diesel generator on diesel governor's classification

Diesel generator set governor classification ① mechanical governor mechanical governor system by corresponding with the diesel engine operating speed rotation Flyweight, Flyweight centrifugal force generated during rotation when the unit automatically adjusts the speed of change the size of the oil pump inlet, so as to achieve the purpose of automatically adjusting unit speed. Figure 2.3 is the principle of centrifugal full speed governor Fig. Position of the mobile operating handle to change the spring tension, so that pulling force and thrust rod pendulum suffered in the new equilibrium position, while changing the pump rack position, so that the diesel engine is adjusted to the desired speed, and automatically stable at this speed. Typically, speed mechanical governor system of diesel generator sets with increasing loadings will slightly decrease, automatic speed range of ± 5%. When the unit with a rated load, speed unit substantially 1500rpm rated speed. ② electronic governor electronic governor is a control engine speed controller. Its main functions are: to keep the engine at idle speed can be set; the engine operating speed can be maintained at a preset speed without being affected by changes in the load. Electronic governor mainly by the controller, speed sensors, actuators, composed of three parts: an engine speed sensor is a variable reluctance electromagnet, which is mounted on the flywheel housing flywheel ring above. When the teeth of the ring gear from below by the electromagnet will generate an alternating current induction (a tooth to produce a cycle). Signal with a preset value electronic controller compares the input and sends a correction signal to the actuator or maintain signal; and a controller can be a variety of adjustments, you can adjust the idle speed, running speed, sensitivity and stability of the controller , start fuel quantity, engine speed acceleration; actuator is an electromagnet, it converts the control signal from the controller to the control force. The controller transmitted to the control signal actuator pass through a linkage to the fuel injection pump control rack. ③ speed EFI EFI unit by the electronic control module (ECU) for diesel engines on a variety of information on the engine range of the sensor detects a diesel engine to control the fuel injector, regulates fuel injection timing and fuel injection amount, so that the diesel engine in top working condition. The main advantage of EFI Speed: Through the injection timing of the injector, high-pressure fuel injection quantity and injection pressure electronically controlled diesel engine can achieve optimal mechanical properties; precise control of the fuel injection quantity by the ECU, diesel engine normal operation fuel consumption decreased, more economical; lower emissions, in line with EURO emission standards for non-road combustion engine; through data communication lines can be connected to an external dashboard, special diagnostic tool, easier to install, increasing the detection point of failure, and easier troubleshooting.
