Abstract
The invention discloses an axial-flow type prefabricated pump station which comprises a tank, a flow stabilization plate, a shaft and an axial flow pump. The lower end of the shaft is fixed to the central position of the tank through the flow stabilization plate, and the axial flow pump is fixed to the central position of the lower end of the shaft. Thus, when the prefabricated pump station runs, because the axial flow pump is installed at the central position of the tank and the shaft is installed at the central position of the flow stabilization plate, stress is uniform, and the tank cannot be subjected to partial impact loads or fatigue rupture; besides, the integration level of the pump station is higher, and the service life of the pump station can be prolonged because of reasonable working condition and load arrangement.
Description
Technical field
The present invention relates to a kind of integrated prefabricated pumping plant, for fields such as rainwater-collecting discharge, sewage liftings in plumbing and sewage treatment project.Pumping plant is for water extraction is for potential energy and pressure energy, solves and originates without the sole power of the problems such as the irrigation and drainage under gravity flow conditions, water supply and Water Resource Adjustment & Distribution.Integrated prefabricated pumping plant also can be applicable to the storm-water drainage in flood season of Jiu Cheng old town, to make up the congenital deficiency of low-lying physical features that old town exists in planning and designing, drains the rainwater of alluvial fast, prevents urban waterlogging.
Background technique
Integrated prefabricated pumping plant is few with its floor space, high integration, construction period are short, high-efficiency environment friendly and the plurality of advantages such as cost-saving and be more and more subject to the favor in market.
Integrated prefabricated pumping plant traditional is in the market all adopt scroll casing type proof submersible sand discharging pump as main lifting means, as shown in Figure 1, is centrifugal structure due to what adopt, and it is specific is that flow is less, and lift is higher.Simultaneously, because of its specific structural type, consider the needs of maintenance, and pipeline flowing, promote the side that water pump can only be arranged on tank body, tank body can be caused thus to be subject to eccentric tilting moment F, such long-time running, by causing the local fatigue of tank body excessively to damage, affect working life and the use safety of equipment.And can dead angle be formed at tank body periphery, cause mud to deposit.Therefore, designing and developing rational in infrastructure, the safe and reliable integrated prefabricated pumping plant being suitable for large discharge, the use of low lift occasion, is the real problem being badly in need of at present solving.
Summary of the invention
technical problem:the invention provides the prefabricated pumping plant of a kind of axial flow that can solve the problem, can avoid prefabricated pumping plant in the course of the work local fatigue be out of shape play, the enough producing balanced forces of each bearing part potential energy.With reach equipment can for a long time normal safe use object.
technological scheme:the prefabricated pumping plant of axial flow belonging to the present invention, its core component is as lifting device with the lifting means-employing guide-vane axial-flow pump of axial flow enhanced feature or mixed flow pump, comprise tank body, stabilier, pit shaft and axial-flow pump, described pit shaft lower end is fixed on described tank body central position by stabilier, and described axial-flow pump is fixed on described pit shaft lower center position.
In the perforate of described tank body top center, described pit shaft is fixed on described tank body by fastening flange base; Live with flange cap seal above described pit shaft.
Described pit shaft is connected with outlet pipe, and the position of described outlet pipe can be determined according to designing water gauge size that is high and tank body.
Described tank body and described stabilier size and the model of described axial-flow pump, the diameter of pit shaft are selected according to the design technology parameter of pumping plant and traffic requirement.To realize different demands.
The prefabricated pumping plant of a kind of axial flow of the present invention, can avoid prefabricated pumping plant in the course of the work local fatigue be out of shape play, the enough producing balanced forces of each bearing part potential energy.With reach equipment can for a long time normal safe use object.
Accompanying drawing explanation
Fig. 1 is integrated prefabricated pump station structure figure traditional in the market;
Wherein, 1 ' is tank body, and 2 ' is axial-flow pump, and 3 ' is pressure piping, and 4 ' is guide rod, and 5 ' is intake pipe, and 6 ' is outlet pipe, and 7 ' is mounting hole.
Fig. 2 is the prefabricated pump station structure figure of axial flow of the present invention;
Wherein: 1 is tank body, 2 is stabilier, and 3 is axial-flow pump, 4 be pit shaft, 5 is fastening flange base, 6 for outlet pipe, 7 is pit shaft blind flange, and 8 is intake pipe.
Embodiment
The prefabricated pumping plant of axial flow, by former be arranged on pumping plant tank body side, be replaced by as the former scroll casing type proof submersible sand discharging pump of lifting means the guide-vane axial-flow pump 3 being arranged on tank body central position, be fixed on flange base 5 by pit shaft 4, realize water outlet by outlet pipe 6.
During concrete use, suitable tank body 1 and the model of stabilier 2 size and guide-vane axial-flow pump 3 is selected according to the design technology parameter of pumping plant and traffic requirement, determine the diameter of pit shaft 4, in the top center perforate of prefabricated pumping plant tank body 1, pit shaft 4 is installed, pit shaft 4 is fixed on tank body 1 by fastening flange base 5, and the top blind flange 5 of pit shaft 4 seals, and pit shaft 4 lower end is fixed on described tank body 1 central position by stabilier 2.Axial-flow pump 3 adopts the mounting type automatic coupling of suspending type to be fixed on pit shaft 4 lower center position.Outlet pipe 6 is connected on pit shaft 4, determines that water pipe 6 is arranged on the position (top or inside) on tank body 1 according to designing water gauge size that is high and tank body 1.Direction and the position of water pipe 6 according to requirements can be adjusted with on-the-spot pipeline flowing.When needing maintenance, pit shaft blind flange 7 can be opened, be lifted out axial-flow pump 3, install, overhaul conveniently.When the apparatus is in operation, because axial-flow pump 3 and pit shaft 4 are arranged on the central position of tank body 1, uniform force, tank body 1 is connected with pit shaft 4 by stabilier 2, and as shown in the figure, water outlet flow-shape is stablized.Tank body 1 can not be subject to impulsive load and the fatigue ruption of local.And dead angle and mud alluvial can not be produced.
Meanwhile, because prefabricated pumping plant is in order to quick effluent, be generally applied to large discharge, the occasion of low lift, and this is also the maximum feature of axial-flow pump 3, can reduce number of devices, saves pumping plant investment and operating cost.Tank body 1 and stabilier 2, axial-flow pump 3, pit shaft 4 and fastening flange base 5, outlet pipe 6 and pit shaft blind flange 7 integral installation, make the level of integration of pumping plant higher, and rational operating mode and load are arranged, can extend pumping plant working life.
The foregoing is only preferred embodiment of the present invention, and be not used to limit substantial technological context of the present invention, substantial technological content of the present invention is broadly defined in the right of application, any technology entities that other people complete or method, if with application right define identical, also or a kind of change of equivalence, be all covered by being regarded as among this right.
