Description
Technical field
The present invention relates to a kind of water pump that especially is used in pond, garden and hydrobiose zone.
Background technique
In the reality in this field pump use always, they have the radially active wheel of motor driven, make water to be aspirated with 90 ° angle of yaw deflection.Thereby pump makes the requirement in corresponding layout become rationally, therefore must carry out about 90 ° deflection usually.Though this water pump produces quite high discharge pressure, has relatively little delivery volume.If realize big delivery volume with this pump, so essential power consumpiton is very high.
Summary of the invention
Therefore the objective of the invention is to, realize a kind of water pump that has the efficient of improvement in view of delivery volume.
The invention provides a kind of water pump that is used in pond, garden and hydrobiose zone, comprise a pump case with feed-water end and waterexit end, a driven pump wheel is set in pump case, pump wheel constitutes the diagonal flow type active wheel of the shrouding disc with taper basically, feed-water end and waterexit end are provided with like this, make current Inbound and current outgoing direction be perpendicular to one another basically, and runner vane have an aerofoil profile profile.
By the pump wheel that adopts to constitute the diagonal flow type active wheel of shrouding disc with taper basically, flow by active wheel guiding diagonally, and the less angle of deflection of comparing with the radial-flow type active wheel.Therefore the deflection loss keeps less and efficient is more favourable when carrying big water quantity.The pump of Gou Chenging has following advantage like this, promptly carries the water of more volumes in less pressure.Therefore preferably this pump is used in the filter plant, the little pressure of there, but high volume flow is essential.Consume much smaller power by pump of the present invention than above-mentioned known pump by the efficient of improving with radial-flow type active wheel.Compare with pump also and can obviously constitute more compactly by pump of the present invention with its big volumetric efficiency with traditional active wheel.In order to obtain identical volume flow, the diameter of conventional operation wheel must be big 1.5 times.Compact structure form by pump of the present invention also allows especially cheap manufacturing, because only need relatively little instrument, especially injection moulding tool.
The blade seamed edge of the front of runner vane extends along diagonal.
The blade seamed edge of the front of runner vane is parallel to water (flow) direction ground and extends.
The blade seamed edge of the front of runner vane and the in-profile of pump case constitute a seal clearance.
Seal clearance is arranged in the transition region between feed-water end and the waterexit end.
The shrouding disc of pump wheel has the end of the back of a blade-like.
The shrouding disc of pump wheel has a through hole in the awl point.
The shrouding disc of pump wheel has 80 ° to 100 ° cone angle.
Pump wheel is a moulding, and has at least one by other materials especially metal ring that constitute, die casting.
The waterexit end is arranged on the upside of pump case in central authorities basically.
Description of drawings
Other advantage and details are obtained by the form of implementation of describing in each accompanying drawing of explained later, wherein:
Fig. 1 presses water pump of the present invention with the form demonstration of longitudinal section,
Fig. 2 manifests the pump wheel of the pump of Fig. 1 with the form of the exploded view of perspective.
Embodiment
The water pump of describing have a pump case 1 with one with its motor casing that is connected hermetically 2, they constitute total housing of pump each other.Pump case 1 has a feed-water end 3 and a waterexit end 4, and this waterexit end preferably is arranged on the upside of pump case in central authorities.Inside in pump case 1 is provided with the pump wheel 5 that constitutes the diagonal flow type active wheel between feed-water end 3 and waterexit end 4.This pump wheel is had an X-rayed the ground expression in Fig. 2.
The form of implementation of describing is especially favourable, because the blade seamed edge 8 of the front of runner vane 9 extends along diagonal, the surface that is parallel to water (flow) direction 7 and is parallel to shrouding disc 6.Therefore runner vane 9 can adapt to the profile of fixed pump housing 1, makes them constitute seal clearance 10 at there.In this special structural type, also can be implemented in narrow seal clearance 10 between the pump wheel 5 of fixed pump housing 1 and rotation with the standard of tolerance of member.Thereby this causes little internal leakage stream and the efficient of the hydraulic pressure that causes improving.Pump can constitute especially compactly, if seal clearance 10 is arranged in the transition region between feed-water end 3 and the waterexit end 4.
The pump of the form of implementation of describing is optimized in view of its flow characteristic and its work quietness, and wherein runner vane 9 has the aerofoil profile profile
And the shrouding disc 6 of pump wheel 5 has the end 13 of the back of a blade-like.This external pump wheel 5 meet the good following realization of Flow Distribution in the stream, promptly runner vane 9 meets the inflow direction ground orientation that stream seamed edge 14 is substantially perpendicular to the water feed-water end 3 in.
Center at the awl point of the shrouding disc 6 of pump wheel 5 preferably is provided with a through hole 15 or a hole, and it is used for cooling and ventilation purpose.
Especially at an easy rate pump wheel 5 can create moulding.In order to optimize sealing and sliding properties, be used as the metal ring of supporting base in this preferred injection moulding together.Metal ring 16 form with exploded view in Fig. 2 shows in the back of work wheel shaft 17, still is arranged on the inside of work wheel shaft 17 in the member of finished product.Be bearing on the electric motor 18 by metal ring 16 pump wheels 5, it drives this pump wheel rotatably.
Because its compact structure mode, its high transfer efficiency and its are suitable in this little power consumpiton to mainly first-class for the recycle pump in following use field, continuous service is necessary in these use fields by water pump of the present invention.Can realize tangible energy-efficient with respect to traditional pump.
