Supply various types of specifications of water turbine generator sets and technical transformation Chengdu Fusite Technology Co., Ltd. (formerly Sichuan Emei Machinery Factory) is a high-tech transformation of traditional power generation equipment technology development and production units, has a number of hydropower Senior engineer and sophisticated processing equipment.
The main supply of various types of specifications for hydro-generator units are:
1. Supply various types of specifications for hydro-generator sets and auxiliary equipment.
2. Solve the problem of insufficient reactive power of the unit by transforming the generator.
3. Supply and maintenance of accessories for water turbine generator sets. (Replacement and repair of components such as runners, vanes, front and rear covers, bushings and coils).
4. Rehabilitate the turbine and generator by replacing or repairing the turbine consumables and returning the generator insulation.
5. Unit capacity expansion and other technical consulting services. Our company cooperates with relevant institutes of water conservancy and hydropower science research institutes, research institutes, etc., adopts the most advanced technology at home and abroad, and uses computer to design. It has successfully transformed many hydropower stations across the country and is well received by users. We adhere to the tenet of serving the power station wholeheartedly, carefully designing, meticulously constructing and meticulously serving, and sincerely cooperate with the power station to make efforts to implement the efficiency improvement of the hydropower unit and improve the technical level and economic benefits of the power station. Among the many small and medium-sized hydropower stations that have been built in China, especially in the hydropower stations built before the 1980s, the conditions of the current conditions are limited, the turbines have poor efficiency, the turbines and generators are not matched, the models are improperly selected, and the manufacturing is limited. The low level of technology leads to poor quality of the unit. As the running time of the unit increases, the equipment ages seriously, affecting the safe operation and stable fullness of the unit, which seriously restricts the full utilization of water energy and fails to exert its due benefits. upgrade.
The power station can carry out the technical transformation of the unit capacity increase as follows:
1 Due to the aging of the equipment and the low level of manufacturing process, the output of the unit will not reach the rated power;
2 The actual operating water head of the power station does not reach the design water head, so that the unit output does not reach the rated power;
3 The output of the unit reaches the rated power, but the power station has more water in the flood season;
4 During the dry season, one unit is in low-load operation for a long time (less than 30% of rated power) or needs to store water for power generation.
Based on the experience of the transformation of many power station units, according to the specific conditions of the power station, under the condition that the flow components of the original unit are not changed, the following technical measures are generally adopted for the capacity expansion and transformation:
1 Replace the original runner with a technically superior runner to improve the performance of the turbine.
2 Improve the stator winding material of the generator, increase the cross section of the stator coil conductor, and increase the generator capacity.
3 other technical measures. After the above economical and practical technology to fulfill the capacity of the power station, 100% of the good efficiency, the general unit output can be increased by 10% to 20%, and some even 25% or more, the efficiency can be increased by 2% to 10% or more. We look forward to sincere cooperation to improve the technical level and economic benefits of the power station units with efficient technology.
If you and your customers need a complete set of hydroelectric generating units, please provide the parameters of “how many meters of design head (difference) and design of total flow rate per cubic meter per second” of the user hydropower station, we can choose the best turbine for you.
