Abstract
The utility model discloses a water-cooled double-end-face mechanical seal device for pumps. The water-cooled double-end-face mechanical seal device comprises a main sealing structure and an auxiliary sealing structure. The main sealing structure comprises a sealing seat (1), a first moving ring (2), a moving ring seat (3), a first stationary ring (4) and a plurality of anti-rotating pins. The sealing seat (1) is fixed on the end face of a pump, the first moving ring (2) is in circumferential linkage with a rotary shaft, the moving ring seat (3) is fixed with the first moving ring (2), and the first stationary ring (4) and the anti-rotating pins are arranged outside the rotary shaft. The first stationary ring (4) is circumferentially fixed with the sealing seat (1). The circumferential fixation of the first stationary ring (4) and the sealing seat (1) refers to that a plurality of first gaps (4.1) for allowing one ends of the anti-rotating pins to insert are formed in the inner side of the inner end face of the first stationary ring (4) and the other ends of the anti-rotating pins are fixed in holes of the sealing seat (1).
