FIELD: power machine engineering.

SUBSTANCE: method comprises steps of preliminarily forming one or more openings in cover of each detachable chamber; arranging said opening along axis of threaded openings of tube plate and uniformly along width of detachable chamber in its central zone; using braces in the form of rods with threaded portion and annular stop in one end and with threaded portion, annular stop and plain mounting seat in other end; screwing-in first ends of braces to threaded openings of tube plate until engagement of respective annular stop with outer surface of tube plate; then sealing place of joining tube plate with braces; at placing each cover with braces onto outer surface of tube plate, positioning plain mounting seat of each brace in respective opening of cover until engagement of annular stop with inner surface of cover; placing threaded portion outside detachable chamber; after fastening cover, placing onto threaded portion sealing gasket and screwing-on cap nut.
