Description

A kind of vortex pump configuration

Technical field

The utility model relates to a kind of water pump more particularly to a kind of whirlpool pump configurations.

Background technique

As shown in Figure 1, Figure 2, Figure 3, Figure 4, at present traditional peripheral pump be by a ring-like parallel fluid channels 2 are arranged in the pump housing 1, The speedup pressurization of liquid is realized by wheel rotor 6 after front cover 4 by the axis 3 of motor 5.The rotation of impeller 6 can generate liquid from Mental and physical efforts, because impeller 6 is the multiple tooth shape in two sides, two sides respectively has multiple teeth 62, and rotation enables liquid to be continuously improved in runner 2 Flow velocity, while runner inner wall namely Vortex pump runner sagittal plane 12 to the pump housing 1, form very high impact friction.Separately because of vortex Impeller of pump 6 is that pressure-raising, the tooth 62 on 6 two sides of impeller are separated by impeller interval face 61 section by section by two drive of the faces R 63 liquid, because This liquid, which can not be reached, efficiently promotes area of passage, while because the vibration that two sides is separated by the not parallel generation to be formed also consumes centainly Power influences the flow and lift of peripheral pump, makes its inefficiency.

Utility model content

The utility model provides a kind of whirlpool pump configuration, the purpose is to solve the disadvantage that the prior art, reduces flow loss, Effective discharge and lift are improved, is improved efficiency.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of whirlpool pump configuration, the pump housing including sequential connection, pump front cover, motor, the axis of motor pass through after pump front cover The fixed impeller in end, impeller are located at the pump housing and pump in the blade wheel chamber between front cover, it is characterised in that: the pump housing has the pump housing of annular Runner, pump front cover have the pump front cover runner of annular；Blade wheel chamber has blade wheel chamber's water inlet and blade wheel chamber's water outlet；It is set on impeller There is the flowing hole of a circle circumference uniform distribution, the side wall of each flowing hole is equipped with the overcurrent tooth of protrusion.

Overcurrent tooth is arc overcurrent tooth, and arc overcurrent tooth is arc-shaped on the section parallel with impeller end face, is impeller In the bending shape that the low centre in both sides is high on the vertical section in end face.

Overcurrent tooth is straight overcurrent tooth, and straight overcurrent tooth is linear on the section parallel with impeller end face, is leaf Take turns bending shape high in the low centre in both sides on the vertical section in end face.

Blade wheel chamber's water outlet intersects with pump housing runner afterwards along the axially extending of water outlet.

The utility model has the beneficial effect that

The utility model impeller shape does not have middle septal surface, and liquid can run through impeller, newly-designed impeller overcurrent tooth The shape of arc triangle or straight type triangle preferably can adequately drive lifting liquid area of passage, be promoted section by section.Water is pumped out The runner at the mouth of a river is expanded to close to blade wheel chamber's water outlet, makes liquid after the speed-raising of pressure-raising section by section directly quickly through until water pumps out The mouth of a river avoids forming runner inner wall high-strength impact friction, improve efficiency to reduce loss.

Specific embodiment

In order to illustrate more clearly of the technical solution of the utility model, attached drawing needed in description will be made below Simply introduce, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention, for this field For those of ordinary skill, without creative efforts, it can also be obtained according to these attached drawings other implementations Example.

As shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10:

The Vortex pump of the utility model includes the pump housing 7 being linked in sequence, pump front cover 9, motor 5, before the axis of motor 5 passes through pump In the fixed impeller 8 in end after lid 9, impeller 8 is located at the pump housing 7 and pumps in the blade wheel chamber between front cover 9, and the pump housing 7 has the pump of annular Body runner 73 (namely runner of pump outlet), pump front cover 9 have the pump front cover runner 91 of annular；Blade wheel chamber has blade wheel chamber Water inlet 72 and blade wheel chamber's water outlet 71.

Impeller 8 is equipped with the flowing hole 80 of a circle circumference uniform distribution, and the side wall of each flowing hole 80 is equipped with the overcurrent tooth of protrusion.

Part of the impeller 8 except flowing hole 80 is impeller outer ring 83.

For overcurrent tooth there are two types of form, a kind of overcurrent tooth is arc overcurrent tooth 81, as shown in Figure 11, Figure 12, Figure 13, Figure 14, Arc-shaped such as Figure 14 on the section parallel with 8 end face of impeller of arc overcurrent tooth 81, on the section vertical with 8 end face of impeller In the high bending shape such as Figure 13 in the low centre in both sides.

Another overcurrent tooth be straight overcurrent tooth 82, as shown in Figure 15, Figure 16, Figure 17, Figure 18, straight overcurrent tooth 82 with Linear such as Figure 18, is on the vertical section in 8 end face of impeller high in the low centre in both sides on the parallel section in 8 end face of impeller Bending shape such as Figure 17.

The overcurrent tooth position of both shapes preferably can adequately drive and wear in the flowing hole 80 for directly running through impeller 8 The lifting liquid area of passage for crossing flowing hole 80, is promoted section by section.

The utility model by blade wheel chamber's water outlet 71 along water outlet it is axially extending after can intersect with pump housing runner 73 as scheme 9, also the runner of pump outlet is expanded to close to blade wheel chamber's water outlet 71, keeps liquid directly fast after the speed-raising of pressure-raising section by section Speed passes through until pump outlet 71, avoids forming runner inner wall high-strength impact friction, improve efficiency to reduce loss.
