WAER RING FOR A CONCRETE PUMP |
摘要 |
<p>A pivot pipe for a two-cylinder thick material sludge pump is designed to reduce the rate of wear of the sealing surfaces and flow bores of the pivot pipe and cooperating outlets on the two pump cylinders. As the pivot pipe oscillates from one pump cylinder to the other pump cylinder the contacting sealing surfaces are subjected to abrasion and impact wear. The present invention limits the rate of wear between the contacting sealing surfaces and a portion of the flow bore by fixing monolithic wearing rings on the upstream end of the pivot pipe and on the outlets of the two pump cylinders. The monolithic wearing rings are made of a hard materials such as cemented tungsten carbide.</p> |
