Background technique
Pump turbine is a kind of fluid machinery of way traffic, both can make water pump and draw water, and can do the water turbine generating again, has peak-clipping and valley-filling in electric power system, and functions such as phase modulation frequency modulation are to safeguarding power grid security and stable playing an important role.Mixed flow pump water wheels unit is one of its modal unit form.
The flow passage components of conventional mixed flow pump water wheels unit generally comprise spiral case, stator, francis turbine runner and draft tube.Pump turbine needs way traffic, and spiral case compiles water that runner pumps discharged to the upstream under pumping operation mode, and the next water with the upstream of generating operation mode is introduced runner.Because the restriction of spiral case self structure form, the very difficult while is satisfied two kinds of operating mode needs preferably, has the big and phenomenon such as asymmetric that flows of energy loss.Simultaneously, the structure of spiral case is complicated, has also brought certain difficulty for design and construction.
In addition, the motor generator set of conventional mixed flow pump water wheels unit is used the space separately, by transmitting energy than the long pass moving axis, causes pump turbine group overall space utilization ratio not high during the device operation, and construction cost is bigger.
The model utility content
Goal of the invention: it is well-balanced that the purpose of this utility model provides a kind of water flow inside, simplicity of design, the bulb type mixed flow pump water turbine that space availability ratio is high.
Technological scheme: for achieving the above object, a kind of bulb type mixed flow pump water turbine of the present utility model comprises: there are the frame of water inlet and water outlet, the inner housing that the centre is provided with motor generator set in front and back, form the water route chamber between described frame and the described inner housing, described generator is connected with a runner through main shaft and stretches into described chamber near the water outlet place; Described chamber is positioned at both sides and is provided with some fixed guide vanes, and described chamber is provided with some movable guide vanes near the runner place.
The utility model is in order to realize utilizing better the space, and described inner housing water inlet end is tip-shape, and described frame is provided with unique opening, and the sidewall of frame and inner housing is arc, and water outlet end is plane, forms the water route chamber of bulb type.
The power line of described motor generator set stretches out this water turbine surface through inner housing, fixed guide vane, frame successively.
Described movable guide vane is installed in the described chamber and can rotate around the axis, and axle direction and water (flow) direction are perpendicular.Described movable guide vane plays water conservancy diversion and regulates flow; Fixed guide vane plays a part to connect and water conservancy diversion.
Beneficial effect: a kind of bulb type mixed flow pump water turbine of the present utility model utilizes the bulb type chamber to replace spiral case, water flow inside flows symmetrically, more easily satisfy the needs of pump turbine two-way working, manufacture and design simple, motor generator set is installed in the inner housing of runner top, the space availability ratio height can be reducingd the construction costs.
