Bushing arrangement for seal cavity protection in rotating fluid equipment |
摘要 |
An arrangement (120) of members for a throat bushing for rotary fluid equipment includes a first member (122) that is useful for seal cavities that contain conventional packing, and a second bushing member (132) that will be used in conjunction with the first bushing member if the seal cavity utilize a mechanical seal at the remote end of the cavity. Both bushing members (122, 132) are provided with spiral grooves (140) in a central bore thereof for the removal of contaminants from the seal cavity. The distal end face (124) of the first bushing member is contoured to receive a mating proximal end face (144) of the second bushing member or to also receive the abutting face of a packing ring or a lantern ring. The arrangement of the invention allows an operator to switch between the use of a mechanical seal or conventional packing without having to discard his primary seal cavity protector.
