Abstract
A cleaning assembly for a shaft or a tubular structure such as a telescopic cylinder, which comprises a sealing joint between an outer tubular element and an inner tubular member in translation inside the outer tubular element, a pipe wiper, and a blade positioned in series in relation to the pipe wiper, wherein the blade has a sharp cutting edge and is mounted by adjusting a tool angle thereof and a pressure it creates on an outer surface of the inner tubular member so that when sliding on this outer surface it scraps contaminants such as organic and mineral material off.
Claims13
A cleaning assembly for a structure made of a series of tubular sections arranged in a tubular housing, each of the tubular sections comprising a inner tubular member displaceable in an outer tubular member respectively, said cleaning assembly comprising:
- at least one blade mounted between said inner tubular member and said outer tubular member;
- wherein a tool angle of said at least one blade and a pressure said at least one blade creates on an outer surface of said inner tubular member are adjusted by a compressive joint to continuously scrape contaminants off said outer surface.
A cylinder head having an outer tubular member and an inner tubular member displaceable therein, comprising:
- at least one sealing joint mounted between the outer tubular element and the inner tubular member;
- a pipe wiper mounted between the outer tubular member and the inner tubular member further toward an open end thereof in relation to said at least one sealing joint, and
- at least one blade positioned in series and further toward the open end in relation to said pipe wiper;
- wherein at least one part of an exterior surface of the inner tubular member is hardened and said at least one blade contacts said at least one part of the exterior surface of the inner tubular member with a pressure of at least 10 lb/po.
