Abstract
The invention discloses a multi-water outlet submersible axial flow pump. The multi-water outlet submersible axial flow pump comprises a pump body, and an axial section of an inner cavity of the pump body is harpoon-shaped; a vertically through central tubular inner cavity is formed in the middle inside the pump body; the bottom of the central tubular inner cavity is a water inlet; tubular water outlets are formed in the periphery of the middle section of the central tubular inner cavity and communicate with the interior of the central tubular inner cavity; a submersible motor is arranged at the upper section inside the central tubular inner cavity; the submersible motor is connected with an impeller through a rotating shaft; and the impeller is in the water inlet in the lower section of the central tubular inner cavity. According to the multi-water outlet submersible axial flow pump, the motor directly drives the impeller, a transmission structure of the axial flow pump is simplified, outlet water flow is increased, the cooling effect of the motor in water is better, and the service life of the motor can be prolonged.
Description
Technical field
The present invention relates to high efficiency drainage machinery field, and in particular to a kind of multi-outlet submersible axial-flow pump.
Background technology
With the development of society, agriculture cover, pool oxygen supplement, landscape feedwater, electroplating technology, and sewage treatment plant etc.
A little special trades turn over Water flow-path, are required for a kind of low lift, big flow, low energy consumption, easy to install, moveable high efficiency water
Pump.And at present in existing various water pump, entirely single outlet, though have the advantages that lift is high, used in some particular rows
Industry all has certain deficiency, and major defect is that energy consumption is big, flow is little, installation difficulty, using inconvenience.
The content of the invention
This is to be directed to the not enough of existing various water pump and for the demand of some specific industries using new purpose,
Devise one kind to be not only simple in structure, design ingenious, and flow is big, energy consumption is low.Noise is little, operate steadily, move user
Just multi-outlet submersible axial-flow pump.
To achieve these goals, a kind of multi-outlet submersible axial-flow pump of present invention design, including the pump housing, the pump
Intracoelomic cavity axial cross section is in harpoon shape, and the pump body central authorities are provided with central tubular inner chamber straight-through up and down, the central canal
Shape intracavity bottom is water inlet, and central tubular inner chamber stage casing periphery is evenly equipped with plural tubulose outlet and and central tubular
Inner cavity is connected, and tubulose outlet is arranged with cavity direction in central tubular in angle, intracavity epimere in the central tubular
Submersible motor is provided with position, the submersible motor is connected with impeller, and the centrally located tubular intracavity hypomere of impeller by rotating shaft
In water inlet, the direct impeller of motor simplifies axial-flow pump drive mechanism, and motor cooling effect more preferably, can be with water
Extend the service life of motor.
Further scheme is that the uniform outlet number of the central tubular inner chamber stage casing periphery is 2-4, is reduced out
The resistance of water, increases water flow, effective reducing energy consumption, and outlet is oblique sets up, and the bore of the outlet is identical.
Further scheme is that the inwall of the center cavity epimere is provided with convex tendon/step, and the submersible motor is put
Put or be fixed on convex tendon/step and be provided with gap with center cavity inwall so that current can constantly cool down motor.
Preferably, the impeller is axial-flow pump special impeller, and the impeller adapted multi-outlet pump housing water outlet efficiency is carried at double
Height, makes impeller rotate uniform force, makes pump operation steady, and arbor is not easy to wear.
Further, the water inlet bottom is provided with filter screen.
The beneficial effects of the present invention is：Overall structure is simple, installation, conveniently moving, and big with low lift, flow,
The characteristics of low energy consumption；Multiple outlets for arranging obliquely can reduce water resistance, consume when can effectively utilizes impeller be rotated
Discharge pressure in the horizontal direction, so as to increase water flow；And axial-flow pump special impeller is made, and operate steadily, arbor abrasion
Little, long working life, noise is low.
