Focusing on improving efficiency & benefit and reducing cost, QNP has introduced and digested advanced and mature aerodynamic and thermodynamic design technology from abroad, and has provided steam turbine flow path expansion and efficiency improvement for many power plants. Practice has proved that steam turbine flow path expansion is an important means to improve unit efficiency and safety and reasonably prolong unit service life.
The company has a strong technical team to carry out research and development of steam turbines, generators and compressors
QNP steam turbine uses optimized high-efficiency blade profile, meridian plane profile and clearance of each stage to improve the steam path structure, and uses optimized seal and high speed to improve the energy conversion rate. Advanced DEH system, TSI system and ETS system are used to monitor and protect the operation process.
QNP generator optimizes electromagnetic field, air path and rotor structure, which makes the generator more efficient, simple to maintain and longer in service life.
The product selection and technical scheme calculation of QNP compressor can be carried out according to customer's needs, and the best solution is provided to customers. Compared with other similar products, the efficiency is improved by 5%, and the benefits are maximized for users.
QNP products adopt modularized design, which has the advantages of high efficiency, small dimension and light weight.
Three-dimensional design and transformation of condenser is carried out to reduce the difference of heat transfer end, improve the vacuum degree of exhaust steam and effectively improve the economy of unit. The unit is transformed from water cooling to air cooling.
QNP has provided the transformation service for many power plants to change the extraction condensing unit into extraction back pressure unit, having accumulated rich transformation experience. QNP can do deep transformation of various types of small and medium-sized steam turbine units, so as to improve the steam supply capacity of existing units and the thermal efficiency of power plants, and obtain the best transformation effect with minimum changes.
The main contents are as follows:
1) Steam turbine expansion and transformation: By optimizing the design of steam inlet passage of steam turbine flow path, the area of flow path is increased, and the capacity of steam inlet and exhaust of the unit is improved, so as to enhance the functional capacity of the unit and increase the economic benefit.
2) Generator expansion and transformation. The capacity of the generator can be improved by reducing the internal losses of the generator, increasing the heat-resistant grade of the insulating materials and strengthening the ventilation and cooling without changing the volume, speed and voltage grade of the generator.
