Description
Technical field
The invention belongs to dosing pump field, be specifically related to a kind of fluctuating movable lug constant flow pump.
Background technology
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；Suck, the one-way sealing of outlet requires height, it usually needs using diamond material, and fault rate is high, cost is high.
Summary of the invention
It is desirable to provide a kind of high constant current performance, it is not necessary to the constant flow pump of one-way sealing component.It is specifically related to a kind of fluctuating movable lug constant flow pump.
This invention address that the design philosophy that its technical problem adopts is: abandon piston structure, design a kind of brand-new fluctuating movable lug constant flow pump, the direct rotor driven of motor rotates suction material.
The main technical schemes of the present invention: fluctuating movable lug constant flow pump, including stator, rotor, suction discharge gate, it is characterized in that the collar plate shape rotor shaft one end with movable lug is arranged on on the flat cylinder stator inner bearing of filling block, the other end stretches out and couples with motor outside flat cylinder stator case, in stator, upper left, bottom right axial symmetry arrange semicircle column type filling block, filling block section of diameter is made up of tangent smooth surface, with the circular orbit that flat cylinder stator surrounds dipping and heaving.
Usually, described in collar plate shape rotor radius, be distributed two activity tongue holes axisymmetrically, movable lug is arranged in hole, collar plate shape rotor rotate time, movable lug can filling block section of diameter smooth surface promote under axially free slip, undulatory motion on circular orbit.
In described flat cylinder stator, semicircle column type filling block surrounds the sector shaped chamber of 4 volume mechanical periodicity together with collar plate shape rotor, movable lug, flat cylinder stator case.Collar plate shape rotor rotates, and movable lug produces from filling block region, and sector shaped chamber volume increases and forms vacuum, sucks material, and 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, the midpoint of semicircle column type filling block radius is arranged around inhaling discharge gate.
Described suction/exhousting hole is two suctions, two rows, totally 4.
The present invention is such to running: when movable lug turns to filling block side, filling block smooth surface promotes movable lug to move to the back side of collar plate shape rotor, another movable lug is then pushed back front by the filling block smooth surface at the back side, fan-shaped indoor liquid or initial gas between two movable lugs promote at the movable lug returning to front, 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, along with movable lug rotates, forms the sector shaped chamber that one is gradually big, form vacuum between movable lug and filling block, and material sucks from material sucking port automatically；After material enters sector shaped chamber, fan-shaped indoor liquid promotes at the movable lug returning to front, 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 collar plate shape rotor, and axle facade completes same suction, discharging process symmetrically.So circulation, collar plate shape 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 one week and completes 1 suction, discharging process, and uniformly then the change in volume in sector shaped chamber is uniform for motor speed, and suction, discharging process are also uniform, have been inherently eliminated intermittence, it is achieved constant current.
Fluctuating movable lug constant flow pump as above, material sucking port is only possible to generation negative pressure in each cycle, do not produce material extruding, therefore without one-way sealing, being directly connected to feeding pipe, discharge gate is only possible to generation malleation in each cycle, and material will not be occurred to pour in down a chimney, therefore without one-way sealing, it is directly connected to feeding pipe.
The fluctuating movable lug constant flow pump of the present invention, has high constant current performance, it is not necessary to expensive one-way sealing component, is widely portable to produce, in life, especially Chemical Manufacture, scientific research field.
