Abstract
The utility model discloses an impeller pump which not only has the same high pressure and pump lift as that of a wheel pump, but also has the same large flow rate as that of an centrifugal pump. The utility model comprises a pump body[1], a pump shell[8], a liquid inlet[2], a liquid outlet[5], a drive shaft[7] arranged inside the pump shell[8], and a drive wheel[9]; the utility model is characterized in that: a driven wheel[3] arranged on a driven shaft[4] is preset up inside the pump shell[8]; vanes[6] in the same shape and joggled together are arranged on the drive wheel[9] and the driven wheel[3]. The utility model has the advantages of simple structure, matchable with a plurality of power type, easy manufacturing, easy operation, and flexible running etc.
Description
Technical field:
The utility model relates to a kind of wing pump.
Background technique:
In existing production practices, be extensive use of positive displacement pump and vane type oil pump, the former is comparatively general with the gear pump in the rotor pump, and the latter is comparatively general with centrifugal pump.Gear pump is industrial a kind of rotor pump commonly used, and it is simple in structure, and a pair of working gear is arranged in pump case, and along with the rotation of gear, liquid sucks the pump housing by suction port, advances under gear promotes, and is sent to liquid port and discharges.It is usually used in various pressurized oil systems and the force-feed lubrication system, particularly it is used as high pressure oil pump and uses.The advantage of gear pump is that pressure is big, the lift height, deficiency is that flow is restricted, and vane type oil pump it the force feed of liquid is finished by the bladed wheel high speed rotating, it is high that its rotating speed requires, flow is big, but pressure is less, lift is lower.
Summary of the invention:
The purpose of this utility model provides a kind of wing pump, and the pressure that makes it both to have gear pump is big, and the advantage that lift is high has the big advantage of the flow of centrifugal pump in the vane type oil pump again.
The utility model is to adopt following technological scheme to realize its goal of the invention, a kind of wing pump, it comprises the pump housing, pump case, liquid entering hole, liquid outlet, is located at driving shaft, driving wheel in the pump case, in pump case, be provided with the follower that is installed on the driven shaft, on driving wheel, follower, be provided with identical shaped and intermeshing blade.
Blade on driving wheel described in the utility model, the follower is 3-8.
The back side of blade described in the utility model is involute circular arc, and the front is three sections broken line shapes, and every section broken line also is involute circular arc.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, have simple in structurely, can use multiple power, be easy to make, easy operating, characteristics such as go slick had both overcome the little weakness of gear pump flow, had also overcome the low weakness of blade type centrifugal pump lift, can make the pump that all size differs, be convenient to produce, live and use.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, a kind of wing pump, it comprises the pump housing 1, pump case 8, liquid entering hole 2, liquid outlet 5, is located at driving shaft 7, driving wheel 9 in the pump case 8, is provided with the follower 3 that is installed on the driven shaft 4 in pump case 8, is provided with identical shaped and intermeshing blade 6 on driving wheel 9, follower 3.Blade 6 on driving wheel 9 described in the utility model, the follower 3 is 3-8.The back side of blade 6 described in the utility model is involute circular arc, and the front is three sections broken line shapes, and every section broken line also is involute circular arc.
During the utility model work, rotation along with driving wheel 9, driving follower 3 rotates, the movement locus of blade 6 each points on the two-wheeled is tangent in twos, blade 6 intermeshes again simultaneously, forms potted line, and liquid is under the effect of the blade on the two-wheeled 6, suck the pump housing by liquid entering hole 2, and be sent to liquid outlet 5 discharges.
