Model of hydraulic turbine of haing electric machinery finishs check to experiment in Switzerland

17 ％ , the average efficiency that increase advantageous position is 93.

25% , runner has excellent stability. Hydraulic turbine of compose skin beach develops a purpose to finish, make this company is in 200 meters of head paragraph obtained a model the has world banner level excellent model runner that highest efficiency exceeds 95% , the Luo Sang that finish is indifferent experiment, also proved scientific research of hydraulic turbine of company of haing electric machinery develops the actual strength that competes with the market and reliable reputation. In Feburary 2004, haing electric machinery obtained beach of skin of black river compose with technical advantage the high peak of flow with 5 600 made of baked clay million the production contract of hydraulic turbine, contract forehead is close 400 million yuan. This is afterwards 3 gorge after 700 sign made of baked clay unit this company bear make most the hydraulic turbine of high capacity. As the joyance that win the bid, pressure also followings sb's heels and come. The first, a few big companies that have competitive actual strength domestic and internationally all participated in contend, very tall to requirement of index of hydraulic turbine technology, haing report confidential obtains a project to must be on the technology have an advantage, be about to be taken out have international the tall parameter of advanced level. If the efficiency of model runner wants,be in 94.

5% above, especially the average efficiency increasing advantageous position of the model should be achieved 92.

93% , the hydraulic turbine that develops namely all should have very high efficiency talent to reach these target inside power station moving limits, have very good stability even additionally. The 2nd, because use, is not to have runner to bid, after winning the bid, want to pass design analysis and model test to achieve inside very short time beforehand fictitious index, haing electric machinery once index of short of hypothesis, not only market image can be affected, and can be fined. The 3rd, the achievement of research undertakes except the hydraulic testing stand in haing electric machinery check experiments besides, even abroad indifferent testing stand undertakes checking and accept an experiment finally. Look from above tripartite face, want to complete the development of this project, technical difficulty is great, the requirement is strict, cannot give the error of a bit. To finish this job, set of haing electric machinery great tackle key problem the project undertakes developing, in summary runner of model of 3 gorge right bank develops the base of experience, mastered hydraulic turbine of 200 meters of head through elaborate design and analysis the rule of hydraulic design, through strict quality control produced Gao Shuiping's block mould test facilities and runner, obtained the performance data with hydraulic turbine accurate model through scientific test. Through two rounds development, obtained the hydraulic turbine that contented contract asks finally, and 2004 the preliminary check that stage of I of Gao Shui head will finish the hydraulic turbine in haing electric machinery to owner and each respect expert attend in November experiments, each index achieves a requirement in the round. Subsequently entire model test plant carries international of mulberry of Swiss the name of a river in Shaanxi and Henan provinces is indifferent lab, what by Switzerland on the independent testing stand with accepted international experiment expert of Luo Sang undertakes test test will have positive result is final check and accept, obtained delectable result.
