SCREW PUMP FOR FLUID MATERIAL TO BE CARRIED BY PUMP

摘要

PROBLEM TO BE SOLVED: To provide an eccentric worm pump remarkably improved in nondurability and easy-to-wear properties inherent in this type of pump by providing a plurality of conveying path strip grooves simple in structure. SOLUTION: This worm pump is provided with a driven eccentric worm rotor 2 of spiral rod body shape having the eccentric center 3 offset by an eccentric pitch space (e) from a rotation axis 4 of the eccentric worm rotor 2 and constantly showing the same circle in the cross section, and a pump stator 5 having a stator space 6 for enclosing the rotor 2 rotatably.
