A double-end mechanical seal for follow-up kettle

Abstract

The invention belongs to the technical field of mechanical seals for a kettle and particularly provides a follow-up double mechanical seal for the kettle. The follow-up double mechanical seal for the kettle comprises a shaft sleeve, a static ring I, a dynamic seal component I, a dynamic seal component II, a static ring II, a bearing, a bearing seat, a corrugated pipe component and a locating sleeve, wherein the shaft sleeve is sleeved by the static ring I, the dynamic seal component I, the dynamic seal component II, the static ring II and the bearing in sequence in the axial direction; an outer sleeve and an inner sleeve of the bearing are respectively connected with the bearing seat and the shaft sleeve; the static ring II is connected with the bearing seat through a static ring seat II; the dynamic seal component I and the dynamic seal component II are connected with the shaft sleeve; the static ring I is mounted on a static ring seat I; the static ring seat I is connected with the static ring seat II; the locating sleeve is arranged at the end, far away from the bearing, of the shaft sleeve; the locating sleeve is connected with the bearing seat through the corrugated pipe component. The follow-up double mechanical seal for the kettle is compact in structure, convenient to dismount and stable and reliable in use; the excellent properties of the mechanical seal, the bearing and a U-shaped corrugated pipe are brought into full play; the sealing problem that a rotating shaft of equipment swings and jumps is solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical seals for kettles, in particular to a servo-type double-face mechanical seal for kettles. Background technique [0002] The reaction kettle generally has a large shaft diameter, a slow rotation speed, a certain corrosive medium, low temperature and pressure, and a certain swing and movement of the rotating shaft. It is more difficult to design, process and install the mechanical seal. There are single-end and double-end seals for reactor seals in practical applications. Generally, self-aligning bearings are designed. During operation, the bearings bear a large load. When the reactor is running, the rotating shaft has the problem of swinging and moving, which leads to the relative displacement of the dynamic and static friction pairs of the mechanical seal, which affects the stability of the seal, and the seal leakage occurs, so that the seal cannot reach the design life cycle.

Problems solved by technology

When the reactor is running, the rotating shaft has the problem of swinging and moving, which leads to the relative displacement of the dynamic and static friction pairs of the mechanical seal, which affects the stability of the seal, and the seal leakage occurs, so that the seal cannot reach the design life cycle.
