Abstract
The invention discloses a helical water pump volute chamber structure of an engine water pump, wherein a center of the volute chamber part is an area where an impeller are installed, the impeller is surrounded between a rotary contour line of the impeller and the outer wall of the volute chamber to form a helical water intake channel and a helical water drainage channel connected in sequence, the width of the water intake channel increases gradually and the channel from the water intake channel to the water drainage channel deepens gradually, a separation tongue is designed at the junction of the start point A of the water intake channel and the start point B of the water drainage channel to separate two channels. The structure can thoroughly solve the liquid backflow problem at the junction of inlet and outlet without forming vortex area, and simultaneously reduce resistance of water streams in all directions to promote the efficiency of water pump and lower the noise of water stream.
Description
Technical field
The present invention relates to engine-cooling system, be specifically related to the volute chamber structure of the water pump complement of motor.
Background technique
The quality of the water pump complement performance design of motor not only influences the performance of cooling system, also influences whole energy consumption, NVH of motor etc.And influence the structure that pump performance mainly comprises impeller and water pump volute chamber.
Usually the volute chamber structure of engine water pump as shown in Figure 1: volute chamber is arranged on the pump body, comprises exhalant canal 1 and intake tunnel 2 two-part.Intake tunnel 2 surrounds impeller 3, and its outer wall section is made of 3～5 sections circular arcs, and the volute chamber bottom surface is identical to attachment face 5 size height, and as shown in Figure 2: get M, N on volute chamber arbitrarily at 2,2 section height is identical.
Said structure, because the volute chamber bottom surface is identical to attachment face size height, after current rotate by impeller 3, the outer wall section arc diameter of volute chamber intake tunnel 2 becomes big gradually, intake tunnel 2 is widened gradually, reduced the flow resistance of width direction, but current still can produce impact at depth direction, the current noise is apparent in view.Simultaneously, the starting point of intake tunnel 2 and exhalant canal 1 do not separate fully, and the high-pressure water flow in the exhalant canal 1 is back in the intake tunnel 2 easily, can form backflow at the two jointing place current, produce the whirlpool district, greatly reduce pump efficiency; Water impact can produce bigger current noise on spiral wall in the whirlpool district of jointing place simultaneously, and the power consumption of water pump is increased, and finally causes engine consumption to become big and NVH poor-performing.
Summary of the invention
The objective of the invention is to propose a kind of helical water pump volute chamber structure of engine water pump, reduce the resistance to water-flow and the anti-backflow of all directions, thereby improve pump working efficient at the prior art above shortcomings.
Technological scheme of the present invention is as follows:
A kind of helical water pump volute chamber structure of engine water pump, the center of described volute chamber part be for installing the zone of impeller, surrounds intake tunnel and the exhalant canal that impeller formation links to each other in proper order between the profile line of impeller rotation and volute chamber outer wall, in the shape of a spiral shape; The outer wall section of described intake tunnel is to be made of the arc section that 3～5 sections diameters increase gradually, and the width of intake tunnel is increased gradually;
It is characterized in that: increase from the intake tunnel to the exhalant canal gradually apart from the height of attachment face the bottom surface of described volute chamber part, and promptly channel depth is deepened from the intake tunnel to the exhalant canal gradually.
Further, at the starting point A of described intake tunnel and cut water of starting point B junction design of exhalant canal, two passages are cut off.
Gap between the roulette wheel profile of described cut water and impeller remains between 1～1.5mm.
The present invention is designed to helix structure with water pump volute chamber, from the import to the exit portion, volute chamber is widened intensification gradually, reduce flow resistance simultaneously from width and degree of depth both direction, simultaneously, cut water of design separates the two between intake tunnel and exhalant canal, avoids the high-pressure water flow in the exhalant canal to be back in the intake tunnel.
Adopt main effect of the present invention to be, thoroughly solved the backflow of inlet/outlet jointing place liquid, can not produce the whirlpool district, reduced the resistance to water-flow of all directions simultaneously, thereby promoted the efficient of water pump greatly and reduced the current noise.

Among the figure: 1, exhalant canal (zone of high pressure) 2, intake tunnel (low pressure area) 3, impeller 4, cut water 5, pump housing attachment face
Embodiment
Helical water pump volute chamber structure is as shown in Figure 3: volute chamber is divided into exhalant canal 1, intake tunnel 2 and cut water 4 three parts.The center of volute chamber is for installing the zone of impeller 3, surrounds intake tunnel 2 and the exhalant canal 1 that impeller formation links to each other in proper order between the profile line of impeller rotation and volute chamber outer wall, in the shape of a spiral shape.The outer wall of the intake tunnel 2 of volute chamber is made of 3～5 sections circular arcs, and it is big that arc diameter becomes gradually.Deepen gradually to the size height of pump housing attachment face 5 the volute chamber bottom surface simultaneously, as shown in Figure 4: on volute chamber water-in and water-out passage, get a M, N respectively, 2 section height difference, N point height is greater than the M point, make thus and deepen gradually to the exhalant canal height, in the shape of a spiral shape from intake tunnel.
Because when current drove in impeller 3 rotation, volute chamber was widened intensification gradually, so current suffered resistance on the width of volute chamber and depth direction is all smaller, and current are unobstructed, and the current noise ratio is less.Simultaneously, between volute chamber exhalant canal 1, intake tunnel 2, designed a cut water 4.Cut water 4 is arranged between the starting point B of the starting point A of intake tunnel 2 and exhalant canal 1 (being the junction), gap L between cut water 4 and the impeller 3 roulette wheel profiles remains between 1～1.5mm, both prevented that current from producing backflow phenomenon in the jointing place of exhalant canal 1 and intake tunnel 2, and avoided impeller 3 to beat again and waited and cut water 4 interference because of assembling and rotation.Like this, the efficient of water pump will promote greatly, reduce the power consumption of water pump, finally make the engine consumption reduction and reach favorable cooling effect, and water pump NVH performance is promoted.
