Abstract
A system and method for replacing a sealing arrangement of a grid coupling without removing or disturbing a mechanical connection of the coupling with driver and driven shafts connected to the coupling includes providing combined seal members having gasket seal portions that are integrally formed with radial seal portions and that are disposed between portions of the housing and the rotating seal group of the grid coupling.
Claims7
A method for replacing seals in a grid coupling, comprising:
- providing a grid coupling in an assembled position between two rotating machine components;
- while a rotating group of the grid coupling remains connected between the rotating machine components:
- removing a housing from around the rotating group of the grid coupling;
- removing existing seals of the grid coupling disposed between the rotating group and the housing;
- inserting two seal elements around the rotating group, each of the two seal elements including a gasket portion and two radial seal portions;
- assembling the housing around the rotating group and the two seal elements such that the two radial seal portions are disposed in sliding and sealing relation between the housing and the rotating group and the gasket portion creates a mechanical face seal between flanges of two halves of the housing;
- and
- securing the two halves of the housing together to form the housing.
