Technical problem to be solved in the utility model is the water pump providing a kind of Turbocharged Gasoline Engine, for improving its lift.
The technical solution of the utility model is as follows: a kind of water pump of Turbocharged Gasoline Engine, it is characterized in that: comprise upper shell (1) and water pump spindle (4), wherein be bolted after upper shell (1) and lower shell body (2) docking, by 0 type circle (3) sealing between these two housings; Described water pump spindle (4) upper end is installed with a flange plate (5), this water pump spindle upper end portion and described upper shell (1) endoporus are rotatably assorted, water pump spindle (4) bottom is through the water seal (6) in upper shell (1) endoporus, and water pump spindle (4) underpart is installed with an impeller (7), this impeller can rotate in the installation cavity of described lower shell body (2); Under the impeller plate (7a) of described impeller (7), card is circumferentially evenly equipped with the acinaciform blade of 5-8 sheet (7b), the height of this blade is 25-27mm, the central boss (7c) of the inner near impeller (7) of these blades (7b), and being positioned at circumferentially same, its outer end is concordant with the periphery of the impeller plate (7a); Described impeller (7) bottom-right lower shell body (2) has water outlet (2a), lower shell body (2) immediately below this impeller has water-inlet cavity (2b), and have water intake (2c) in the lower left side level of lower shell body (2), the bore of this water intake is 50-60mm, and water can be extracted into described water outlet (2a) place from water intake (2c) and water-inlet cavity (2b) when impeller (7) rotates.
In said structure, the utility model increases the bore of water intake, increases the height of blade (7b) simultaneously, and optimizes the shape of blade (7b), and these corrective measures combine just can effectively improve this water lift of pump.Meanwhile, the bore of water intake (2c) suitably increases through overtesting, and its present bore is 50-60mm.Learn through test, the lift that this water pump is corresponding when motor speed is under 6800r/min has 21m, has had significantly improve than the 16m of conventional construction, so just can meet the usage requirement of 1.5L discharge capacity turbo supercharging gasoline engine well.In addition, the utility model has abandoned steel pad original, and adopts 0 type circle to seal upper shell (1) and lower shell body (2), and sealing effect is better so on the one hand, effectively can reduce manufacture cost again on the other hand.
For the ease of manufacturing, the number of described blade (7b) is 6, and these blades (7b) and the impeller plate (7a), central boss (7c) integrally casting are shaping.
Beneficial effect: the utility model increases the bore of water intake, increase the height of blade simultaneously, and optimize the shape of blade, so just can significantly improve this water lift of pump, thus meet the usage requirement of 1.5L discharge capacity turbo supercharging gasoline engine, and the utility model adopts 0 type circle to seal upper shell and lower shell body, sealing effect is better so on the one hand, effectively can reduce manufacture cost again on the other hand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of impeller in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of water pump of Turbocharged Gasoline Engine, is formed primarily of upper shell 1, lower shell body 2,0 type circle 3, water pump spindle 4, flange plate 5, water seal 6 and impeller 7.Wherein, be bolted after upper shell 1 and lower shell body 2 dock, sealed by 0 type circle 3 between these two housings.Described water pump spindle 4 upper end is installed with a flange plate 5, to accept power by this flange plate 5, and then drives water pump spindle 4 to rotate.Described water pump spindle upper end portion and upper shell 1 endoporus are rotatably assorted, and water pump spindle 4 bottom is through water seal 6, and this water seal 6 is fixedly mounted in the endoporus of upper shell 1.
As shown in Figure 1, 2, the underpart of water pump spindle 4 is installed with an impeller 7, and this impeller can rotate in the installation cavity of described lower shell body 2.Described impeller 7 is made up of impeller plate 7a, blade 7b and central boss 7c, and its Leaf 7b and central boss 7c is located at the lower card of impeller plate 7a, and this three is by casting integrated shaping.Described blade 7b is tulwar shape, and its number is 5-8 sheet, and can be preferably 6, and these blades 7b is circumferentially distributed on the lower card of impeller plate 7a, and the bending direction of these blades 7b is consistent.Further, the thickness of blade 7b increases to present 4-8mm by original 2-5, and can more preferably 5,6,7mm, design is to improve water lift of pump like this.Meanwhile, the height of blade is 25-27mm, and can more preferably 25.5,26,26.5mm, the inner of these blades 7b near central boss 7c, and is positioned at circumferentially same, and its outer end is concordant with the periphery of impeller plate 7a.
The bottom-right lower shell body 2 of described impeller 7 has water outlet 2a, the lower shell body 2 immediately below this impeller 7 vertically has a water-inlet cavity 2b, 2b is up-small and down-big for this water-inlet cavity, is conducive to the impact that reduction blade 7b is subject to like this.And have a water intake 2c in the lower left side level of lower shell body 2.The bore of water intake 2c is 50-60mm, and can more preferably 52,55,58mm, and the shaft axis of water intake 2c is vertical with the shaft axis of water-inlet cavity 2b, so just effectively can reduce the impact force that blade 7b is subject to, this and the shaft axis of conventional construction water intake 2c and the shaft axis conllinear of water-inlet cavity 2b have very large difference.When impeller 7 rotates, water can be extracted into described water outlet 2a place from water intake 2c and water-inlet cavity 2b.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
