Application Case-Yanka Pumping Station

 

Project Overview>>>

Yanka Pumping Station is located in the urban area of Jingzhou City. It undertakes the task of drainage in urban areas, pumping urban waterlogging water to the lower reaches of the river bend in Shashi, Yangtze River. It is located in the subtropical monsoon humid area, with rain and heat in the same season, distinct seasons, abundant rainfall, sufficient light, mild climate, long frost-free period, and suitable for the growth of crops such as grain, cotton, and oil. It has superior climate conditions for agricultural development. The average annual rainfall is 1079.7mm, of which the rainfall from April to October accounts for 79.2% of the whole year. The annual average evaporation is 1285.5mm, the frost-free period of the year is 255d, and the average relative humidity is 80%. The drainage standard is that the urban area of Shacheng, Baolian District and Shashi Farm will be eliminated after 24 hours of heavy rain for 24 hours in 20 years. In the Cenhe District, there will be 24 hours of heavy rain and 24 hours of drainage in the Cenhe District. The gong field area reached 10 years, one day, one day, heavy rain, and three days to the depth of the crop. The flood control standards on the outer river side are the same as those on the Jingjiang embankment. The design flow rate of the pumping station is 55m/s, 6 mixed-flow pumps are selected, and 6 1800kW mixed-flow water pump motor units are installed in the pump room.

 

Yanka Pumping Station is a rear layout scheme. The main buildings of the pumping station include the main pumping room, installation room, auxiliary workshop, substation, trash rack (bridge), inlet pond, diversion channel, outlet box culvert and outlet channel. The project is a large (2) type project such as II. The flood gates and dike-crossing buildings are level 1 buildings, the remaining main buildings are level 2, and the secondary buildings are level 3.

Application Case-Jiepai Hub

 

Project Overview >>>

The Jiepai Water Control Project consists of ship locks, control gates, pump stations and Puhe control gates. Jiepai hub pump station is a bidirectional pumping station with a design flow of 300m/s. It is equipped with 9 sets of X-shaped bidirectional flow channel open hydraulic full-adjustable vertical axial flow pumps. The stand-alone design flow rate is 33.4m/s, supporting 2000kW vertical synchronous motor, rated voltage 10kV. The control gate is provided with 5 holes, a single hole is 16m wide, the total net width is 80m, and the maximum discharge and discharge flow is 745m/s. The ship lock is a class VI ship lock, the length of the lock chamber is 180m, the width of the lock chamber and the door is 16m, the threshold depth is 3.0m, the design ship type is a 100t class cargo ship, and the check ship type is a 300t class cargo ship. Puhe Gate is located on the Pu River on the north side of the Jiepai Junction, 500m away from the New York City of the Jiepai Junction. It is a control project under water system adjustment. The net width is 18m and there are three holes.
