Introduction
Steam Turbine Screw Air Compressor is driven by power supply from an industrial compressor, compress the air in an compressing cavity and then pressurize the conpressured air. They are primarily applied in power plants and steam reutilization industry, and can significantly improve the returns of enterprises for their energy conservation perfromance.
Take the application to power plants as example, the in-boiler high pressure steam is supplied to the steam turbine of the generating set to generate power to drive the power generator, and after that, the pressure of steam discharged from the steam turbine remains to be approximatedly 2 Mpa. Before the use of a steam turbine compressor, such steam is cooled by the cooler and then transported to boiler in the from of water. The steam turbine compressor, however, draws on the steam from the steam turbine to drive the compressor to generate compressed supplied to other equipment.
Product performance:
Steam turbine compressors are provided with excellent governing system which is based on german siemens technology and internationally cutting-edge. The governing system is safe and reliable, wide in regulating range, highly automatic, etc, able to realize remote automatic control of rotaional speed anf load and connect DCS system directly.
The bearing,both front and rear, of the steam turbine compressors are disposed in the inner oil tank and can be wiell lubricated and cooled, completely preventing the trouble of high oil temperature.
Speed govering valve: the speed govering is vital to normal operation of steam turbine conpressors, and if the speed govering valve works flexibly and its useful life in turn underlie critically the performance of the govering system. Through the improvement in its structure and processing trvhniques, the operating performance of the speed govering valve is made to be flexible, free of air leakage and have a long service life,etc.
The air compressor and the steam turbine are driven by a coupling. The output shafe of the steam turbine is directly connected to the bare compressor on the frame via a resilient coupling. The internal system of the compressor unit comprises air intake system, air regulating and protection system, cooling system, electric control system, safety and protection system, and all the components are installed onto the high-strength chassis.
Control system enables the air compressor to automatically regulate the capacity within a certain range to satisfy the requirments of users for changes in the qir flow.
PLC master controller manages and monitors the entire air compressor system, and for its simple man-machine interface, can well familiarize an operator with the specific operation status of the unit. In addition, this master controller has remote control function and relevant interface, thus enabling users to operate online and the management center to control a group of compressors at the same time.
