Abstract
The invention discloses an elliptic gear pump consisting of two half elliptic disk gears having shafts which are meshed vertically with each other and are assembled in an enclosed inner cavity of a pump body. When the two elliptic disk gears having shafts perform a synchronous opposite torque rotation in a gear tooth transmission fit, due to the sealed isolation for the position of a friction sealing surface of the gear tooth having complementary changes of the shaft radiuses, the volume of a structural sealed working space, formed by the radius difference between a major axis and a minor axis of the two elliptic disk gears, continuously forms an expanding process, a transferring process, and a disappearing process of the volume of a structural sealed working space, and the working processes of continuously suction of a material liquid by a liquid inlet on the pump body and continuously high pressure delivery of the material liquid by a liquid outlet on the pump body. The elliptic gear pump belongs to the rotary high-pressure piston pump, which can be used as an oil well pump in the oil field, a high-pressure pump for delivering water or liquid, and a metering delivery pump.
Description
Affiliated technical field:
The present invention relates to a kind of industrial pump.
Background technique:
The gear pump of industrial present use has only annular gear pumps, it is the meshing and rotary piston pump that constitutes of a kind of mutual subtend of round tooth wheel disc by two same sizes, because annular gear pumps is to utilize expansion, transfer and the disappearance process of two gear disk subtend moments of torsion when rotation tooth socket space volume to reach the purpose of continuous sucking and force feed fluid, therefore, annular gear pumps only is suitable for float amount high-pressure delivery process.Applicant once designed and the elliptic gear pump patent of invention (application number: the applying date :) of having declared relative big discharge capacity vacuum sucking of a kind of tool and high-pressure delivery characteristics.
Summary of the invention:
The structural design scheme of the Chinese invention patent that the present invention is intended to application number to be carries out patent again to be declared.
The objective of the invention is to reach with following structural design scheme: 1/2nd elliptic gear dishes of structure centre axle cooperate the tool axle to be assemblied in the appropriate location of pump housing intracavity space with the meshing gear teeth transmission fit structure sliding friction sealing junction of the mutually vertical subtend of major axis radius before and after the tool of two same sizes; And the wheel crest top land that makes two tool axle elliptic gear dish major axis radius two ends is in lubricated friction or the friction sealed junction state of sliding friction or gap with the outside major axis radius inner chamber peripheral wall surfaces of co-located respectively, and the end walls plane of two tool axle elliptic gear dishes then is in the lubricated friction of axle radius or the friction sealed junction state of sliding friction or gap with the plane, two side of pump housing inner chamber respectively. One of them that is in two tool axle elliptic gear dishes of the meshing drive mechanism state of subtend is the outer power engine that drives of driving tooth wheel disc axle connection； another then the gear teeth moment of torsion toggle action for according to the directed rotation of driving tooth wheel disc the time make the subtend driven tooth wheel disc of rotation synchronously； do except that the online axle of driving tooth wheel disc and to wear the wall axle sleeve mount； other gear disk dish axle then all the tool axle be assemblied in the built-in axle sleeve of pump housing inner chamber end wall.The water outlet of the pump housing ( liquid ) pore and water inlet ( liquid ) pore then are arranged at the neutral position of lower peripheral wall on the pump housing inner chamber respectively, form elliptic gear pump of the present invention by said structure.
When the present invention drove by outer power machine axis connection that initiatively elliptic gear dish axle (5) is done continuous directed rotary course, the active elliptic gear dish (3) that is in the meshing gear teeth transmission of subtend mated condition and driven elliptic gear dish (4) then were in mutual meshing friction on the axle head spacing link position according to it respectively and connect cross-section seal isolation effect and the subtend torque drive effect between principal and subordinate's gear teeth that face formed pump housing intracavity space and also formed the subtend rotary course that continuous complementary reducing transmission cooperates simultaneously.Since the structural seal operation spatial volume that two tool axle elliptic gear dishes have formed satellite according to the equidistant semi major axis seal isolation effect of sliding of its major axis radius two ends body wall circumference on the major axis radius inner chamber perisporium of the outside with the outside minor axis radius perisporium of wheel disk body separately jointly with and the directed circumference transfer process of structural seal operation spatial volume.Rotate to belong to and then formed reducing synchronously and disappearance process and process is dwindled in the corresponding synchronous extruding that has formed the structural seal operation spatial volume of satellite and the volume feed liquid is tending towards being extruded the current drainage process of discharging the pump housing of the structural seal operation spatial volume of satellite when shortening the meshing axle head spacing link position that connects the face seal relation of a radius wheel disc when the structural seal operation spatial volume of satellite is tending towards orientation.Then corresponding synchronous increase that has formed the structural seal operation spatial volume of satellite and recovery process and correspondingly formed the synchronous expansion recuperation of the structural seal operation spatial volume of satellite and be tending towards flowing through journey when the structural seal operation spatial volume of satellite is tending towards directed rotation and shortens the meshing axle head spacing link position that connects the face seal relation of a radius wheel disc away from genus by the suction of external environmemt inspiration feed liquid.Then formed during continuous subtend rotary course that two tool axle elliptic gear dishes do in pump housing cavity that above complementary reducing gear teeth transmission cooperates the present invention treat carry feed liquid reduce pressure simultaneously (quantitatively) suction with high pressure (quantitatively) thus the defeated continuous operation tendency of row reached by pump housing water inlet (liquid) mouthful end continuously (relative) big flow decompression suck and wait to carry feed liquid and while to hold continuously (relative) work purpose of discharge capacity high pressure dispatch internal volume feed liquid greatly by pump housing water outlet (liquid) mouth.
The invention belongs to the rotating type high-pressure reciprocating pump, compare with the knuckle-tooth wheel pump of same specification and have relative big high-pressure delivery discharge capacity, can be used as oil pump, high pressure water delivery (liquid) pump and metering conveying pump.
Description of drawings:
With reference to the accompanying drawings structure of the present invention is elaborated below:
Accompanying drawing 1 is a uncovered structural front view of the present invention.
