Abstract
The utility model relates to an axial-flow type motor pump. A rotor shaft of the utility model is hollow; the inner wall of a water lifting head on one end of the rotor shaft is provided with a blade wheel, and the other end is provided with a connection member; the periphery of the water lifting head is provided with a protective cover on a casing. The utility model integrally combines a motor and a pump; the utility model can be used as an electric generator and can also be used as the pump, and the utility model takes the place of the existing various centrifugal pumps for a submersible pump, a pipeline pump, a blower, marine power, etc. The motor pump has the advantages of simple and compact structure, less material consumption, use efficiency improvement, convenient installation, use and maintenance, etc.
Description
The utility model relates to a kind of power source of electromechanical integration.Be suitable for flowing in the occasion that object is carried and the object that needs to flow is used as power.
At present, the power equipment that the object that is used for flowing is carried generally all combines (as submersible pump, blower fan etc.) by independent motor and centrifugal pump or blade.This kind equipment is loosely organized, consumption material is many, the inconvenience maintenance, and can't cool off, send a telegraph the utilization efficiency decline of machine to motor.
The purpose of this utility model is intended to overcome above-mentioned shortcoming, and the inventor links together machinery and power, a kind of compact structure is provided, saves raw material, improves utilization efficiency, electric axial flow machine pump easy to maintenance.
The purpose of this utility model is to realize like this: be made up of housing, stator, rotor, rotor shaft, bearing and seal ring.Its rotor shaft center has through hole, and this rotor shaft one end has the water lift head, the other end has link; Water lift head inwall has impeller, has the safety cover on housing around the water lift head.
Impeller is an aial flow impeller.
The stator coil two ends seal with seal ring.
Housing of the present utility model, stator, rotor, bearing, rotor shaft are to make by existing electric motor structure principle design, just the rotor shaft transformation of the way are quill shaft.After the stator coil energising, magnetic field is driven and is sailed rotor motion, and rotor drives quill shaft and rotates and drive water lift head, impeller rotation, and fluid is carried to the other end from an end of quill shaft, plays the function of pressurization, water lift, thereby has realized the purpose of this utility model.
The utility model is owing to improve a little on the basis of existing motor, dexterously motor and pump are combined, it can be made small hydro generator and use, can make pump again uses, all kinds of centrifugal pumps that replace existing submersible pump, pipeline mounted pump, blower fan and power peculiar to vessel etc. to use, have simple and compact for structure, volume is little, consume that material is few, good heat dissipation effect, raising utilization efficiency and be convenient to advantages such as installation, transportation, use.
Below in conjunction with accompanying drawing the utility model embodiment is elaborated:
Fig. 1 is a kind of structural representation sectional view of the utility model.
Referring to Fig. 1: form the submersible pump structure by housing 1, stator coil 2, rotor 3, rotor shaft 4, bearing 5, rubber seal 6, flange plate 7, safety cover 8, water lift head 10, aial flow impeller 9.Stator coil 2 is fixed on the housing 1, and rotor 3 is supported in the housing 1 by rotor shaft 4, and rotor shaft 4 is bearing on the housing 1 by bearing 5, and the seal ring 6 at sealed stator coil 2 two ends also is installed between rotor shaft 4 and the housing 1.Through hole has been opened at rotor shaft 4 centers; the one end fixedly is equipped with by the silk mouth water lift head 10 is housed; fixing on water lift head 10 inwalls (connecting or casting with screw) has impeller 9; that water lift head 10 outsides have is fixing (screw connects or the casting) safety cover 8 (also can claim vacuum chamber) on housing 1, rotor shaft 4 the other ends have flange plate 7 as link (flange plate and this end are that screw or silk mouthful or cast is connected).
Bearing 5 of the present utility model adopts standard ball rolling bearing (thin 200 series); Water lift head 10 also can be made one with rotor shaft 4; Be used for submersible motor and the Ordinary Centrifugal Pumps motor does not need radiating structure; For the ease of pressurization, on rotor shaft 4, can establish a plurality of aial flow impellers; Flange plate 7 also can be silk mouthful (consider when pump uses that pipeline does not rotate with rotor shaft 4, need to adopt one do not transmit change the joint of turning round and pipeline being connected with rotor shaft and communicating and get final product).
Output flow of the present utility model and pressure can be controlled by rotor 3 speed governing, and the impeller distribution and the quantity that also can change in water lift head 10 or the rotor shaft are carried out flow and pressure adjustment.
During use, plug in, rotor shaft 4 makes that the impeller 9 in the water lift head 10 sucks fluid from outside, and exports from the other end by rotor shaft 4 inwalls under the drive of rotor 3, can finish the conveying of fluid, replaces existing all kinds of pumps.
