In the western part of Georgia, there is an old Pelton power plant built in 1950's, with rated capacity 12Mw, that is 3 sets of 4000Kw pelton turbine unit. Rated water head is198meter, and water flow is 2.1cums per unit. The runners adopted welding structure. Even though it has been repair weld every two or three years till 2008, it wears and tear severely and the inner surface of the buckets are rough and uneven with many breach on the edge. Of course it debases the output efficiency.
Our company supplied 2 sets of whole pace casted stainless steel runner and forged shaft to replace the old ones. After commissioning, we cheerfully see that the unit efficiency improved more than 5%. Surly, people of the power plant are very happy to see that also and in 2009 they ordered other 2 sets of same runner and shaft again.
Our quality control is following CE requirement, and other related international standards. This sample tells us that, we not only supply the whole unit but spare parts.
