GEAR PUMP AND OPERATION METHOD OF GEAR PUMP

摘要

PROBLEM TO BE SOLVED: To provide a gear pump in which gaps between bearings and gear rotors can be accurately adjusted in a simple structure, and its operation method.SOLUTION: A gear pump 1 comprises: a casing 2 including a suction port and an exhaust port; a pair of gear rotors 5 formed by integrating gear parts 3 with shaft parts 4 respectively and arranged so as to be engaged with each other in the casing 2; and bearing parts 6 for supporting the shaft parts 4 so that the gear rotors 5 are rotatable. The bearing parts 6 can move along the thrust direction of the gear rotors 5.
