The utility model discloses an impeller blade design is the curved formula blade of turning over, can be under the condition that does not increase impeller outside diameter, can promote the flow and the lift of water pump by a relatively large margin, and on the other hand is close to the partly of impeller import limit wheel hub side owing to pruned, can increase the impeller inlet flow rate under the condition that the flow increases like this, reduces impeller import limit and to the impact of coolant liquid, has reduced energy loss.
Description
Technical field
The utility model relates to technical field of automobile, particularly relates to a kind of backward swept vane water pump.
Background technique
Existing engine water pump, impeller blade is helix shape, the tangent line in front side of vane outlet port and the angle of pump housing vortex chamber helix tangent line are acute angle, impeller blade outlet laying angle is less than 90 degree, interlobate runner is longer and unobstructed, water conservancy loss is less, is conducive to reducing the efficiency that air horsepower promotes water pump; And impeller inlet cincture shell side direction water sucking mouth extends, hub side liquid can be made ahead of time by the effect of blade, can cavitation be prevented.
Existing engine water pump impeller, when designing, if need the flow and lift significantly promoting water pump, must increase impeller outer circular diameter, but between engine air in unallowed situation, cannot significantly promote engine water pump performance.
Model utility content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, provides a kind of backward swept vane water pump, solves available engine water pump significantly cannot promote engine water pump performance between engine air problem in unallowed situation.
For achieving the above object, the utility model by the following technical solutions:
A kind of backward swept vane water pump, comprise the pump housing, belt pulley, shaft connecting bearing and water seal assembly, the described pump housing comprises housing and impeller, described impeller comprises wheel hub and some backward swept vanes, described backward swept vane is arranged on wheel hub, and the part of described wheel hub deflection impeller inlet is thinner than other parts, and described impeller is positioned at housing and is fixedly connected with the transmission shaft of shaft connecting bearing, described transmission shaft and belt pulley are coaxially arranged, and described water seal assembly is arranged between impeller and shaft connecting bearing.
Preferably, the external part of described transmission shaft is fixedly connected with belt pulley.
Preferably, between described transmission shaft with described belt pulley for interference fit is connected.
Preferably, described impeller is fixed with the mode by interference fit between shaft connecting bearing and is connected.
The beneficial effects of the utility model are:
1, impeller blade of the present utility model is designed to backward swept vane, when not increasing impeller outer diameter of a circle, can promote the flow and lift of water pump by a relatively large margin;
2, the utility model has been pruned a part for close impeller inlet cincture shell side, when flow increases, can increase impeller inlet flow further, reduce impeller inlet limit to the impact of cooling liquid.
3, transmission shaft of the present utility model and belt pulley, mode all by interference fit between impeller with shaft connecting bearing are fixed and are connected, and have structure simple, centering property is good, and bearing capacity is high, the load that can withstand shocks and the advantage little to the strength reduction of axle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front schematic view of the pump housing;
Fig. 3 is the 3-D view of the pump housing;
In figure: the 1-pump housing, 2-shaft connecting bearing, 3-belt pulley, 4-water seal assembly, 5-impeller, 6-blanking cover, 7-motor volute, 8-water outlet, 9-water intake, 51-backward swept vane, 52-wheel hub.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises for forming the pump housing 1 of volute chamber with motor volute 7, the pump housing 1 comprises housing and impeller 5, blanking cover 6 is positioned on housing, impeller 5 comprises wheel hub 52, be located at cover plate on wheel hub 52 and some backward swept vanes 51, backward swept vane 51 is arranged on wheel hub 52, and impeller 5 is installed in housing.This water pump also comprises belt pulley 3, shaft connecting bearing 2, water seal assembly 4, and impeller 5 is fixedly connected with by the mode of interference fit with the transmission shaft of shaft connecting bearing 2, and the mode that external part and the belt pulley 3 of transmission shaft are connected by interference fit is fixed connection.Transmission shaft and belt pulley 3 are coaxially arranged, thus will be located at the transmission of power of the motor of outside to impeller 5 by belt pulley 3, and are realized the pump water function of water pump by the rotation of impeller 5.Wherein, in order to avoid the water in water sucting cavity excessively leaks outside, water seal assembly 4 between impeller 5 and shaft connecting bearing 2, is provided with.
By other parts being thinner than wheel hub 52 that impeller 5 import cincture shell side part is cut in the utility model, impeller 5 inlet side can be reduced to the impact of cooling liquid, when pump intake 9 flow increases, energy loss can be reduced further.
The working principle of this model utility is: engine crankshaft belt wheel drives the belt pulley 3 of water pump complement to rotate, the belt pulley 3 of water pump complement drives water pump bearing and impeller 5 to rotate, cooling liquid in water pump supplies impeller 5 from water intake 9, because cooling liquid is thrown out of, pressure reduces in the center of impeller 5, cooling liquid in water tank is inhaled in impeller 5 through water intake 9 under the differential pressure action at unit fixed on water pump suction and impeller 5 center, realize the reciprocation cycle of cooling liquid, under the influence of centrifugal force cooling liquid is got rid of the vortex chamber to pump body 1 when impeller 5 rotates, produce certain pressure simultaneously, then cooling liquid flows out from water outlet 8.As shown in Figures 2 and 3, impeller 5 blade design of the present utility model is backward swept vane 51, when not increasing impeller 5 outside diameter, greatly reducing the energy loss in conversion process, improve the efficiency of centrifugal pump and improving the flow and lift of water pump.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
