2.35MPA Steam Turbine And Generator,
3000kw Steam Turbine And Generator,
2.35MPA steam turbine generator
This series of turbines can simultaneously supply electric power and steam for industry usage. Both heat and electric load can be adjusted. It is especially suitable for self-support power stations and district central heat power stations in chemical, textile, sugar and paper making enterprises, where certain electric power is needed and heat load should be adjusted.
Steam turbine electric control system:
The whole electronic control system includes:
3.1 Speed regulation performance: the speed regulation system adopts DEH speed regulation mode, the controller will set the steam turbine speed and the actual speed comparison calculation, output 4 ~ 20HA control signal to the electronic actuator, in order to control the action of the actuator, to achieve speed regulation on the spot.The controller can also receive the 4 ~ 20HA analog signal transmitted by the upper computer, and connect it with the DCS system by manually switching on the spot to realize remote control.Requirement governor selected control module and other electrical instrument components should be used today's most advanced, responsive adjustment, no load fluctuation.
3.2 Speed regulation range 0 ~ 6000r/min.Tripping speed is 110% of the rated speed or set according to user requirements.The speed regulation system to ensure that the installation size and the buyer's site consistent;
The vibration, tile temperature and other operating parameters meet the relevant national standards.
Vibration amplitude of steam engine ≤0.03mm (vibration amplitude of fan ≤0.03mm)
Turbine bearing oil return temperature (Ċ) ≤65.
3.3 Turbine safety protection (overspeed protection)
(1) The turbine must be equipped with a mature and reliable emergency security system to prevent overspeed.The operation value is 110 ~ 112% of the rated speed, and the reset speed should be higher than the rated speed.The emergency security device is also provided with a reliable action indicator and a test device for the operation of the emergency security device that can be moved.
(2) The steam turbine is also provided with an additional overspeed protection device, whose operating speed is 110 ~ 112% of the rated speed.
(3) The tripping system of the emergency security system has interlock protection to prevent the steam turbine from suddenly re-entering steam.
(4) the time from the operation of the emergency guard to the complete closure of the main steam valve should be less than 1 second.
(5) The steam turbine unit is respectively installed on the operating platform of the unit control room and on the place of the steam engine with manual emergency shutdown operation device.
