The utility model discloses a vane pump with
noise reduction structure relates to vane pump technical field, through starting drive source and drive rotor to rotate, and the setting of vane in
centrifugal force and first spring telescopic spare makes in the shell realization liquid suction and
discharge, two connecting pipes are responsible for the suction and
discharge of liquid, when needing to install vane pump, by pulling
handle and making a counterweight no longer be limited, by setting the sliding connection between counterweight and shell, under the gravity of counterweight, two counterweights are close to each other, make the barrier band no longer block the connecting
pipe, then rotate
handle, because of the threaded connection between
handle and limiting plate, make handle be taken off, make the setting of handle can not influence the connection of connecting piece.
