The Simulation During Start-up Transition of Bulb Type Tubular Pumping Station

In order to grasp synchronous motor starting process in the large-scale bulb type tubular pumping station, the parameter of dynamic capacity, equipment lifts, voltage, current, rotational speed along with the starts process time, the starting process theory of pump set was detailed analyzes and the simulation computation was carried on. From the pump system, using rigid body dynamics, hydrodynamics and hydraulic machinery complete characteristic theory, various kinds of dynamic characteristics of the pump system are analyzed and mathematic model during the start-up transition for large-scale tubular pump station is established. As to No.3 pumping station of Huai'an, different important parameters and their variation are announced through simulation during the start-up transition for large-scale tubular pump station, such as rotating speed, flow, delivery lift, torque and so on. The research results have important theory directive significance to tubular pump station design and reliable operation.
