摘要 | PROBLEM TO BE SOLVED: To prevent reduction of operation time of a gear pump which may be caused by precipitation of silver due to electrolysis of an emulsion of silver halide in the gear pump provided with two gears rotating in opposite directions to each other by forming recessions on the side surfaces of the gears, each having a sharp edge toward the rear side in a rotational direction. SOLUTION: In a gear pump, gears 3, 4 are rotatably housed inside a space formed on a plate 1. In addition, a transferring space 5 and a sucking space 6 are formed. The gear 3 are driven in the direction indicated by an arrow, and at the same time, the gear 4 is driven in the opposite direction. Narrow groove-like recessions 7 having sharp edges 8 on the rear side are formed on the side surfaces of the gears 3, 4. The recessions 7 are extended toward the peripheries of the gears 3, 4, almost reaching the bottoms of the gears 3, 4. In such a gear pump, some emulsions of silver halide is precipitated in the recessions 7 generated during usage and transfer. Reuse is started after removing the precipitated silver.
