Abstract
The utility model belongs to the improvement of a water pump. A motor long shaft fixed on a pump body is provided with a centrifugal impeller in the pump body, a rotating impeller and a despinning disk in sequence in a penetrating mode. Compared with existing water pumps, the utility model has the advantages of compact structure, low rotation speed, low noise when working, large flow quantity, low failure rate and long service life and is suitable for the conveyance of various fluids.
Description
The utility model belongs to the improvement of water pump.
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.
The purpose of this utility model is the 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 utility model is: motor (1) major axis that is fixed on the pump housing (2) is coated with the pump housing (2) interior centrifugal impeller (3), propeller runner (4), racemization dish (5) successively.The major axis tail end that motor (1) extends in the pump housing (2) is supported on the anti-friction bearing (6).
The utility model is compared 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 utility model.
Fig. 2 is the propeller runner structural representation in the utility model.
Fig. 3 is the partial sectional view of Fig. 2.
Fig. 4 is the racemization dish structural representation in the utility model.
Fig. 5 is the plan view of Fig. 4.
Centrifugal impeller of the present utility model (3) is centrifugal water-wheel radially; Propeller runner (4) is illustrated in figure 2 as the wheel body that is provided with vane sheet (10) between outer shroud (8) and wheel hub (9); 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.
