Description

The rotation plate type swinging vane pump

Technical field: the utility model relates to a kind of fluid pump, relates in particular to a kind of rotation plate type swinging vane pump.

Background technique

Present piston gas compressor and the liquid pump that uses, a port open of its cylinder body, an end face of the closed end of cylinder body and piston can only constitute an active chamber, and piston makes a round trip can only finish to inhale and flows--and work cycle of-current drainage, efficient is low, power consumption is big.And all kinds of centrifugal pumps, axial-flow pump, mixed flow pump, plunger pump etc. also exist cavitation erosion, the not high defective of efficient.

The model utility content

The purpose of this utility model is exactly that efficient is low, power consumption is big for existing gas compressor and liquid pump unreasonable structure cause, and a kind of rotation plate type swinging vane pump that provides.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of rotation plate type swinging vane pump, comprise pump case, rotating vane axle and rotating vane, turntable shaft and rotating disk, pump case is provided with the influent stream valve, the current drainage valve, it is characterized in that: the two ends of pump case cylindraceous are sealed with end cap, the coaxial rotating vane axle that is provided with in the pump case, the two supports of rotating vane axle seals movingly on end cap and with it, and have at least an end to stretch out from end cap, the axially outer affixed rotating vane of rotating vane, the periphery of rotating vane respectively with the inner wall sealing of pump case and end cap movingly, pump case is provided with a turntable shaft outward, and turntable shaft becomes the staggered and synchronous same-speed rotation of space 90 degree, affixed rotating disk on the turntable shaft with the rotating vane axle, outer rim by rotating disk inwardly has breach, this breach tolerable rotating vane passes through, and rotating disk incision pump case is between two sides and pump case and end cap of rotating disk, form sealing movingly respectively between the outer rim of rotating disk and the rotating vane axle, be respectively equipped with the influent stream valve on the pump case of rotating disk both sides, the current drainage valve, both arrange against the rotating vane sense of rotation.Its working principle is: rotating vane and the rotating disk synchronous same-speed rotation that has breach, when rotating vane was about to pass rotating disk, the rotating disk breach also forwarded the pump case inner chamber simultaneously to, and the rotating disk breach is aimed at and passed to rotating vane just, forward another side to, make rotating vane can not be obstructed every continuous rotation.When the rotating disk breach turns over the pump case inner chamber of pump case, real plate closed on both sides, rotating disk and rotating vane and axle, pump case and end cap surround the inner chamber of a sealing jointly, this moment, the influent stream valve was opened, suck fluid, when the rotating disk breach forwards the pump case inner chamber again to, this process finishes, when the rotating disk breach turn over pump case again, and when forming closed inner chamber again, the influent stream valve sucks fluid once more, rotating vane pushes the fluid of the last round of suction of front side simultaneously, pump from the current drainage valve, finish a work cycle.Continue to repeat above-mentioned work cycle, realize continuous operation, the rotating vane rear side is constantly pumped from the current drainage valve by the extruding of rotating vane front side again constantly from influent stream valve inspiration fluid, enters pipeline.In addition, as when ignoring the rotating disk breach and forwarding the pump case inner chamber to, the small backflow of advance, the current drainage valve is of short duration is to simplify pump structure, also can be provided with open in usual to advance, drainage port.

The beneficial effects of the utility model are: owing to adopted this programme, simplified pump structure, improved working efficiency, big, the not high defective of efficient of cavitation erosion, volume of effectively having avoided all kinds of reciprocating pumps, centrifugal pump, axial-flow pump, mixed flow pump, plunger pump, vane pump to exist.In addition, the utility model rotation plate type swinging vane pump also can be directly uses as pneumatic motor or fluid motor, inserts high-pressure liquid in inflow port, can drive vane and axle rotation, and the low-pressure fluid after the work is discharged from drainage port.

Below in conjunction with drawings and Examples the utility model is further specified.
