The maximum diameter rotor of the Harbin Electric Electric Development Tibetan area realizes the "zero -match weight"

Recently, the completion ceremony of the first unit of the water turbine of the Batang Hydropower Station was successfully held at the Harbin Pattop Wheel Machining Base in Harbin Power in Ganzi Prefecture, Sichuan Province. The first turntable manufacturing of the "zero -match" boutique manufacturing by Harbin Electrical Machinery Factory Co., Ltd., which is independently developed by the Harbin Electric Co., Ltd., has achieved the "zero -allocated weight" boutique manufacturing, and contributes Harbin power to helping the creation of a national large -scale landscape water storage demonstration base.

The maximum diameter rotor of the Harbin Electric Electric Development Tibetan area realizes the "zero -match weight"

In January 2019, Harbin Electric obtained the development contract of 3 water turbines in Batang. After more than 3 years of R & D, design, and careful manufacturing of 10 months, the first turntable was officially completed. It successfully passed the acceptance and perfectly achieved the "zero -all".

The first unit water turbine rotor, with a maximum diameter of 7.7 meters, 4.82 meters high, and a total weight of 215 tons. It is currently the largest mixed -flow wheel in the system in the Tibetan area. All the welded seams of the Batang spinning wheels are 112 meters. After welding, the inspection is qualified once. After the exquisite processing, all measurement indicators meet the standard requirements; Zero -match "Boutique manufacturing.

The rotor is the core component of the water turbine that converts the energy of water flow into mechanical energy. It is compared to the "heart" of the water motor unit. A state of manufacturing of the remnant unbalanced torque marks the high level of manufacturing in terms of overall balance.
