Abstract
The present invention belongs to the improvement of a water pump. A long shaft of a motor fixed on a pump body orderly penetrates through a centrifugal impeller, a rotating impeller and a despin disk. Compared with the existing water pump, the present invention has the advantages of compact integral structure, low rotating speed, low noise during working, large flow quantity, low failure rate and long service life, and is suitable for conveying various kinds of liquid.
Description
Technical field
The invention belongs to the improvement of water pump.
Background technique
People common water pump, constitute by the centrifugal impeller in the pump housing and the pump housing usually.During use, the motor drives centrifugal impeller is realized the conveying of liquid, rotating speed height when its major defect is pump working, and noise is big, and fluid flow is little, is easy to be out of order, and working life is short.
Summary of the invention
The objective of the invention is shortcoming at above-mentioned existence, provide a kind of when making pump working noise little, the compound water pump that fluid flow is big.
Technological points of the present invention is: a kind of combined pump, have the motor and the pump housing, it is characterized in that: be fixed on motor 1 major axis on the pump housing 2 and be coated with centrifugal impeller 3, propeller runner 4, racemization dish 5 in the pump housing 2 successively, the major axis tail ends that motor 1 extends in the pump housing 2 are fixed on the anti-friction bearing 6, and centrifugal impeller 3 is centrifugal water-wheel radially; Propeller runner 4 is for being provided with the wheel body of vane sheet between outer shroud and wheel hub; Racemization dish 5 is for having the sheet disk of a plurality of open-works, and its cylindrical place is a threaded body.
The present invention compares with existing water pump, its compact overall structure, and rotating speed is low; Noise is low during work, and flow is big, and rate of fault is low, long service life; Be applicable to the conveying of various liquid.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the propeller runner structural representation among the present invention.
Fig. 3 is the partial sectional view of Fig. 2.
Fig. 4 is the racemization dish structural representation among the present invention.
Fig. 5 is the plan view of Fig. 4.
Embodiment
Centrifugal impeller 3 of the present invention is centrifugal water-wheel radially; Propeller runner 4 is illustrated in figure 2 as outer shroud 8 and 9 wheel bodys that are provided with vane sheet 10 of wheel hub; Racemization dish 5 is for having the sheet disk of a plurality of open-works 7, and its cylindrical place is a threaded body.
During installation, penetrate centrifugal impeller on the pump housing built-in motor axle, propeller runner successively and all connect with key or screw, the racemization dish be by screw thread or screw at pump housing inner bottom part, keep and the less gap of propeller runner, anti-friction bearing is loaded on the inner bottom surface of the pump housing, is used for the supporting motor axle.
During use, motor drives centrifugal impeller and propeller runner rotate, and carry liquid by propeller runner and centrifugal impeller; The racemization dish that is fixed on the pump housing is used to eliminate rotating vortex, guarantees working pressure, augmented flow and flow velocity.
The extension mode that connects the pump housing adopts and is threaded, and also can adopt form connections such as flange.
