Description
Technical field
The invention belongs to metering pump field, be specifically related to a kind of fluctuating movable lug constant flow pump.
Background technique
Plunger type constant flow pump is in production, life, especially one of Chemical Manufacture, the most widely used general machinery of scientific research field.But the intermittence of plunger motion is its familiar lacunas; The one-way sealing of suction, exhaust port requires high, and usually need to use diamond material, and rate of fault is high, cost is high.
Summary of the invention
The present invention aims to provide a kind of high constant current performance, without the need to the constant flow pump of one-way sealing component.Be specifically related to a kind of fluctuating movable lug constant flow pump.
The present invention solves the design philosophy that its technical problem adopts: abandon piston structure, design a kind of fluctuating movable lug constant flow pump completely newly, motor straight tape splicing moves rotor turns suction material.
Main technical schemes of the present invention: fluctuating movable lug constant flow pump, comprise stator, rotor, suction discharge gate, it is characterized in that being with disc type rotor shaft one end of movable lug to be arranged on the flat cylinder stator inner bearing of band filling block, the other end stretches out outside flat cylinder stator case and connects with motor, in stator, upper left, bottom right axisymmetric arrange semicircle column type filling block, filling block section of diameter is made up of tangent smooth surface, surrounds the ring track of dipping and heaving with flat cylinder stator.
Usually, described in disc type rotor radius, distribute two activity tongue holes axisymmetrically, and movable lug is arranged in hole, and when disc type rotor rotates, movable lug axially can be free to slide under the smooth surface of filling block section of diameter promotes, phugoid motion on ring track.
In described flat cylinder stator, semicircle column type filling block surrounds the sector shaped chamber of 4 volume mechanical periodicity together with disc type rotor, movable lug, flat cylinder stator case.Disc type rotor turns, movable lug produces from filling block region, and sector shaped chamber volume increases and forms vacuum, and suck material, movable lug proceeds to filling block region, sector shaped chamber volume compression, discharges material.
Described on the upper and lower front cover of flat cylinder stator, near the mid point of semicircle column type filling block radius, suction discharge gate is set.
Described suction/exhousting hole is two suctions, two rows, totally 4.
The present invention operates like this: when movable lug turns to filling block side, filling block smooth surface promotes the back side that movable lug moves to disc type rotor, another movable lug is then pushed back front by the filling block smooth surface at the back side, fan-shaped indoor liquid between two movable lugs or the movable lug that initial gas is getting back to front promote, and discharge from discharge gate under fixing filling block extruding; When this movable lug produces from filling block opposite side, movable lug is pushed back front by the filling block smooth surface at the back side, and along with movable lug rotates, between movable lug and filling block, form the gradually large sector shaped chamber of one, form vacuum, material sucks from material sucking port automatically; After material enters sector shaped chamber, the movable lug that fan-shaped indoor liquid is getting back to front promotes, and discharges from discharge gate under fixing filling block extruding.
While this movable lug completes said process, another movable lug is at the back side of disc type rotor, and axle facade completes same suction, discharging process symmetrically.Circulation like this, disc type rotor often rotates one week, and its front completes 1 suction, discharging process, and its back side also completes 1 suction, discharging process axisymmetrically.
Fluctuating movable lug constant flow pump as above, rotates and within one week, completes 1 suction, discharging process, and the Volume Changes of motor speed evenly then in sector shaped chamber is even, and suction, discharging process are also even, fundamentally eliminate intermittence, realize constant current.
Fluctuating movable lug constant flow pump as above, only negative pressure may be produced in material sucking port each cycle, do not produce express material, therefore without the need to one-way sealing, direct connection feeding pipe, only may produce malleation in discharge gate each cycle, material can not occur and pour in down a chimney, therefore also without the need to one-way sealing, directly feeding pipe is connected.
Fluctuating movable lug constant flow pump of the present invention, has high constant current performance, without the need to the one-way sealing component of costliness, can be widely used in production, life, especially Chemical Manufacture, scientific research field.
