Banduo Hydropower Station is located in Banduo gorge, Xinghai County, Hainan Tibetan Autonomous Prefecture, Qinghai Province. The control basin area above the dam site is 107520 square kilometers, the normal pool level of the reservoir is 2760 meters, and the total storage capacity is 15.35 million cubic meters. It has daily regulation performance.


Bando hydropower station on the plateau
Banduo hydroproject is mainly composed of concrete dam on the left bank, flood gate, riverbed type power station powerhouse, concrete auxiliary dam on the right bank, switch station and external traffic road. The maximum dam height is 78.72m. The grade of the project is class II large (2), and the permanent main buildings such as water retaining, flood discharge, water diversion and power generation are class II. The average annual power generation is 1.412 billion kwh.


Micro special pin sensor
The cooperation project between Weite and Banduo power station is the repair of the grabbing beam, including the grabbing beam hydraulic pump station and the threading pin displacement sensor. The waterproof sealing junction box, deep-water navigation plug and pin penetration sensor included in the underwater signal transmission solution of hydraulic grab beam independently developed by Weite company are all made of 316L all stainless steel. From material selection to production, there are strict controls. Through strict flaw detection and monitoring, the underwater pressure can reach 7MPa, with strong anti-interference ability, good sealing performance, impact resistance and corrosion resistance, It can meet the requirements of severe environment such as water depth of 200 meters and high temperature and low temperature.


Abb1.5kw variable frequency motor selected for the motor transformation of the pump station
The oil tank of the hydraulic pump station is made of 10mm thick carbon steel and designed and manufactured according to the pressure of 7MPa. The imported sealing ring and double-layer seal are adopted to improve the sealing material of the oil cylinder. The oil tank is provided with oil filling hole, oil drain hole and observation hole.
The gear pump adopts Parker gear pump with large flow, high pressure and high power. The pump has the advantages of small leakage and high volumetric power, and is widely used in medium and low pressure hydraulic systems.


The electromagnetic control hydraulic valves in the pump station are arranged on an integrated valve block, which is located on the oil tank. The pressure resistance of the hydraulic oil filter and the strength of the filter element meet the technical requirements, and the filtering accuracy is 20 & mu; m. Meet the cleanliness requirements of the system for oil quality.


The most reliable test of underwater products is the launching test. Lift the products installed in place into the water and soak them for more than ten hours before testing the function of the pin. This process is the most test of the sealing of underwater products. If the product is flooded, there will be abnormalities when the pin is worn or returned, and even the 380V short circuit will be caused. The consequences can be imagined.


After several days of immersion, many sets of grabbing beam products installed by Weite in Banduo Hydropower Station can still be worn and returned normally. They have successfully passed the underwater test and won the approval of customers.
Whether in the Yellow River basin or the Yangtze River Basin, whether in the South or the north, whether in the plateau or the plain, Weite has been working hard to solve the pain and difficulties of customers.
