Abstract

This pump is the fluid pump relevant with axial-flow pump and centrifugal pump.In the past motor and impeller separately, blade is contained on the pump shaft that rotor drives and constitutes impeller, wheel rotation produces centrifugal force or lift conveyance fluid.And this invention is integrated motor and impeller, by stator coil and inboard blade is arranged, and the outside is made up of the cylindric solid of rotation that the excitation material of excitation effect constitutes, and has cancelled pump shaft.Do the rotor rotation with solid of rotation, the acting in conjunction of blade and cylinder produces the lift conveyance fluid.

Description

1, affiliated technical field:
This pump is and axial flow, the relevant fluid pump of Centrifugal water pump in the past.
2, the structure of pump integrating and description of use:
Rotary pump in the past generally is made up of major components such as pump case, impeller, suction chamber, pumping chambers, and wherein suction chamber or pumping chamber are installed stator sometimes.There are the following problems for such pump:
(1) need to be equipped with motor, motor and impeller can not be made of one.
(2) device area is big, uses inconvenient.
(3) complete sets of equipment cost height.
(4) impeller easily stops up, and must reequip when solid, foreign matter are arranged.
(5) big to the influence of pump proper functioning during inspiration gas.
(6) viscous force between pump case inwall and fluid is big.
The invention of pump integrating has solved the problems referred to above.Simple and compact for structure, easy to use, it is little to the influence of pump proper functioning that foreign matter, gas are sneaked into the back, and the effective radius of coil and excitation body increases the corresponding increase of opplied moment relatively.
That is to say, rotary pump in the past, the centrifugal force or the lift conveyance fluid that utilize the impeller of rotation to produce, impeller by pump shaft by motor drives.And this invention is integrated motor and impeller, by stator coil and inboard blade is arranged, and the garden tubular solid of rotation that the outside is made of the excitation material of excitation effect is formed and cancelled pump shaft.Rotate as rotor with solid of rotation, the acting in conjunction of blade and solid of rotation produces the lift conveyance fluid.
In the accompanying drawing, Fig. 1, Fig. 2, Fig. 3, Fig. 4 are respectively planimetric map, sectional arrangement drawing, left view, the housing A-A sectional drawing of pump integrating electric motor with vane wheel.
In the accompanying drawing, Fig. 1, Fig. 2 have illustrated the formation of this invention. The outside is housing and stator coil, and inside is rotary body. The rotary body outside is the excitation part, and the inside one deck is the casing play as rotary body, and this layer is connected with the blade of excitation part and inboard. There are the bearing of the rotary body skeleton that is overlapping and the sealing device that seals in the rotary body two ends. Pump housing both ends are suction chamber and pumping chamber.
Under the alternating current effect, produce magnetic force, rotary body rotates, and the blade of rotary body produces lift and carries fluid.
Each several part is described below one by one:
(1) housing C: the solid of rotation that is both ends open.Inwall has the fixed coil device, and device form is various.Housing has the cable extending port, and the outlet port seals not flowing water, and the housing two ends have the attachment hole and the garden arc boss that connect suction chamber and pumping chamber to play supporting role to overlap bearing.Outside the arc boss of suction side, have and stop that bulge loop is to bear the opposition of bearing.Garden arc boss and stop that bulge loop all is parts of housing.
(2) stator coil J: identical with the coil of general motor, be fixed on inner walls, sealed insulation also has cable (K) to be connected with external power.
(3) solid of rotation (E, F, H 1, H 2):
Solid of rotation is made skeleton F with metal garden tube, inlays excitation material E outward, in connect blade, Placement is regardless of.Can be that garden tube skeleton is fixed with the garden jacket casing that the excitation effect is arranged together.The inner blade of solid of rotation is divided into lift force blade H 2Guide vane H 1, their shape is all similar to axial-flow pump, and the way that available welding or screw connect is fixed on the solid of rotation inwall, and the dense degree of its established angle and blade size, blade, the group number of blade are decided on use condition.
(4) bearing: be enclosed within the solid of rotation two ends, rotating body for supporting, suction side thrust-bearing L, extrusive edifice guide bearing I, bearing is fixed by the garden arc boss on the housing.
(5) sealing: in bearing and solid of rotation, solid of rotation and housing, each solid of rotation joint, the cable tail hole is located all must take seal approach, in order to avoid water enters the space between housing and the solid of rotation, influences the running effect of pump.G is a seal arrangement.
(6) insulation: the coil in the pump housing must insulate, in order to avoid electric leakage.
(7) suction chamber D and pumping chamber B: be the prolongation pipe that is connected on the housing two ends.
(8) adjust ring M: play the role of positioning.
Operation instruction: the same at pump operation before-image general fluid pump, allow it be full of fluid earlier.As required, change the size and the established angle of blade, increase and decrease group number.Can use by general pump, also can make usefulness such as deep-well pump, submersible pump, or use as the pipeline booster pump of general water pipe.

Claims (2)

1, this pump is the pump integrating electric motor with vane wheel relevant with axial-flow pump and centrifugal pump, and it is by solid of rotation (E, F, H 1, H 2), stator coil (J), suction portion (D), ejection portion (B), housing (C), bearing (I, L), seal arrangement formations such as (G), it is characterized in that:
A, with solid of rotation as rotor, stator coil is connected as a single entity motor and impeller as stator,
B, solid of rotation are by the interior side-entry blade (H of garden tubular solid of rotation skeleton (F) 1, H 2), outside edge excitation material (E) is formed,
The surrounded of c, solid of rotation the stator coil that is fixed on the housing, and when connecting ac power supply, promptly the driven rotary body rotates.
2, according to claim 1, the impeller of pump integrating electric motor with vane wheel is by dress blade H in the tubular skeleton F of garden 1, H 2Constitute.
