What is the impact of digital valve governor
2021-03-24 12:03:17
Impact digital valve governor is designed for impact turbine generator developed a new type of governor. Digital valve mechanical hydraulic servo system with electrical control part, constitute the impact of digital valve governor. In general, the current impact governor adopts the most advanced direct-coupled adjustment method without a linkage mechanism and the governor directly controls the injection needle relay to adjust the unit frequency and load, and the deflector does not participate in the adjustment function. Only when the unit speed suddenly increased by 10% (this value can be arbitrarily set), the deflector is quickly put into and cut off the jet; when the speed is lower than the set value, the deflector returns to the initial position. For multi-nozzle impact generator, the needle injection and withdrawal by the electrical control section based on load and needle position automatically controlled. Depending on the number of nozzles, one set or several sets of digital valve servo system are used to control one or several sets of spray needle relay, one or several sets of spray needle relay can all be put into automatic or manual operation at the same time, Requires any combination of its mode of operation. Automatic, manual operation can be smoothly switched to each other. The governor is equipped with hardware and software that interface with the computer monitoring system. High-performance and high-quality imported original electrical components, high standards of configuration, low oil requirements, can fully guarantee the power station to achieve unattended (or less vigilance) requirements. Features and Features 1. Adopt independent hydraulic control circuit to control the nozzle and deflector respectively 2. No lever to improve the precision of the speed regulation system 3. With fail lock function 4. Adapt to multi-nozzle control system 5. Working pressure: 2.5 /4.0/6.3MPa
