The invention provides an integrated spring compensation and mechanical-seal moving ring assembly. The integrated spring compensation and mechanical-seal moving ring assembly is composed of a moving ring, a moving ring holder, a compensation spring, a transmission ring and a sliding seal ring. Guide rod clamping hooks (6) are symmetrically arranged at the left end of the moving ring holder (2). The outer ring surface of the transmission ring (4) is provided with a platform (41) and open grooves (44). The guide rod clamping hooks (6) are matched with the open grooves (44) to enable the moving ring holder (2) to be connected with the transmission ring (4) in a hooked mode. The cylindrical compensation spring (3) is installed between the moving ring holder (2) and the transmission ring (4). The integrated spring compensation and mechanical-seal moving ring assembly is simple in structure and cooperative relationship, small in radial size, particularly suitable for an occasion with a smallradial installation space, and convenient to maintain.
Description
technical field [0001] The invention relates to a mechanical seal device, in particular to a spring compensation mechanical seal moving ring assembly suitable for occasions with small radial installation space. Background technique [0002] The moving ring assembly of the prior art spring compensation mechanical seal device includes a moving ring, a moving ring seat, a sliding sealing ring, a transmission seat, a compensating spring, a push ring, and a shaft sleeve. The moving ring seat, transmission seat and push ring are installed on the outer ring surface of the shaft sleeve. Anti-rotation pins and compensation springs are arranged between the moving ring seat and the transmission seat. The static ring assembly is installed between the shaft sleeve and the gland. There is a fixed ring on the shaft sleeve of the gland, and a lug hook mechanism is provided between the fixed ring and the outer end surface of the gland, so that the moving ring component, the static ring compo...
