Abstract
The invention discloses an automobile engine pump assembly chamber structure. The whole liquid flow surface is spirally widened and deepened to a liquid outlet. A spiral surface is deepened gradually from the starting point to the ending point and is formed by four different circular arc sections. Because the shell of the liquid pump adopts the spiral surface, the chamber structure for the shell of the liquid pump provides better movement locus for the flow of the liquid and has the characteristics of low power consumption, high efficiency and larger lift. The predictive analysis and the final verification of the performance of the automobile engine pump assembly chamber structure shows that the automobile engine pump assembly chamber structure can ensure that the liquid pump has the efficiency of 20 percent when the liquid pump has the rotation speed of 2000 r/min and the flow rate of 45 L/min and has the efficiency of 45 percent when the liquid pump has the rotation speed of 7300 r/min and the flow rate of 165 L/min.
Description
Technical field
The present invention relates to the motor car engine fitting field, be specifically related to a kind of automobile engine liquid pump assembly chamber structure.
Background technique
Auto pump is for car engine cooling system provides circulating cooling liquid, and it is the rotation through impeller, and liquid acquisition energy and high speed are circulated.Generally most of liquid can circle round in the water pump chamber and do useless merit, reduces hydraulic power greatly, forms pump efficiency phenomenon on the low side.Generally, water pump when rotating speed 2000r/min, flow 45L/min, its efficient less than 15%, when rotating speed 7300r/min, flow 165L/min, its efficient less than 35%.
Summary of the invention
The object of the present invention is to provide a kind of automobile engine liquid pump assembly chamber structure.
In order to address the above problem, the present invention takes following technological scheme:
A kind of automobile engine liquid pump assembly chamber structure; Adopt spiral way to widen at whole flow plane and be deep to the outlet port; Helicoid is progressively deepened from origin-to-destination; Helicoid is made up of four different arcs sections, 14 ° of helicoid width direction helicoid starting point and cut water angles, 105 ° of depth direction helicoid starting point and cut water angles.
Said helicoid progressively adds from origin-to-destination and is deep to 5mm.
Above-mentioned arc section is to choose central point on 3.2cm, 3.54cm, 3.61cm, the 6.32cm circle at radius respectively.
The outlet end bottom design is become circular-arc.
The pump cut water is close to impeller.
Cut water and impeller span 1～1.5mm.
Beneficial effect of the present invention is: because the water pump shell adopts the mode of helicoid, said water pump shell chamber structure is the mobile movement locus preferably that provides of liquid, and it is low to have power loss, and efficient is high, the characteristics that lift is big.Above-mentioned project organization is carried out performance prediction analysis and final checking, and when rotating speed 2000r/min, flow 45L/min, pump efficiency reaches 20%; When rotating speed 7300r/min, flow 165L/min, pump efficiency reaches 45%.

Embodiment
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the present invention done further detailed explanation.
The object of the present invention is to provide a kind of automobile engine liquid pump assembly chamber structure.Said water pump shell chamber structure is the mobile movement locus preferably that provides of liquid, and it is low to have power loss, and efficient is high, the characteristics that lift is big.
With reference to Fig. 1; The technical solution adopted for the present invention to solve the technical problems is: adopt spiral way to widen at whole flow plane and be deep to the outlet port; Width direction helicoid starting point 1 and 14 ° of cut water 7 angles; Depth direction helicoid starting point 2 and 105 ° of cut water 7 angles make liquid not have the ground of impact and get into chamber (Fig. 1) from impeller 8.Consider that the chamber sectional area changes the performance characteristics influence, when helicoid 4 designs, helicoid 4 is made up of R1, R2, R3, four arc sections of R4.
The pump chamber end face change to consider that face area influences pump characteristics, as far as same impeller, if the pump chamber face area is too small, and flow---head curve steepening then, best efficiency point moves to the small flow direction, and efficient reduces; If the pump chamber face area is excessive, then flow---head curve is more smooth, and best efficiency point moves to big direction of the traffic, and efficient also reduces.Thereby when helicoid designed, the center changes respectively chose central point on R3.2cm, R3.54cm, R3.61cm, R6.32cm circle, guarantee that face area satisfies the Fi=Qi/2V patterns of change all the time.Qi/2 in the formula---the i end face is through the amount of liquid of pump chamber; V---the flow velocity of i end face liquid.V=(0.7～0.85) V
0, V
0---impeller eye speed.
Center of arc chooses central point (Fig. 2 and Fig. 3) respectively on Φ 1, Φ 2, Φ 3, Φ 4 circles; When helicoid 4 design, breasting the tape from starting point 23 progressively adds and is deep to 5mm (Fig. 4), guarantees that the arbitrary sectional area that began the impeller rotating center from starting point 1 satisfies the Fi=Qi/2V patterns of change all the time.Qi/2 in the examination---the i section is through the amount of liquid of pump chamber; V---the flow velocity of i section liquid.Cause energy loss in outlet end bottom 6 because of the right angle reason forms vortex for fear of liquid, outlet end bottom 6 is designed to circular-arc (Fig. 4).In volute, do the rotation that contrary impeller turns to for fear of liquid, generally pump cut water 7 is close to impeller 8.In this programme, choose cut water 7 and impeller 8 spans 1～1.5mm, avoid interval too small to produce vibration, the contrary impeller of excessive liquid turns to rotation (Fig. 1) at interval.
Above-mentioned project organization is carried out performance prediction analysis and final checking, and when rotating speed 2000r/min, flow 45L/min, pump efficiency reaches 20%; When rotating speed 7300r/min, flow 165L/min, pump efficiency reaches 45%.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
