Embodiment Construction

[0026] In FIGS. 1 and 2 , the conveying direction is correspondingly indicated by the arrow FR.

[0027] FIG. 1 shows a delivery pipe 1 with a double-layer pipe body 2 comprising a highly wear-resistant hardened inner pipe 3 and a pressure-resistant outer pipe 4 . The wall thickness of the inner tube 3 is s 1 Indicates that the wall thickness of the outer tube 4 is represented by s 2 express. It can be seen that the wall thickness s of the inner tube 3 1 greater than the wall thickness s of the outer tube 4 2 .

[0028] A coupling shoulder 7 or 8 is attached to the inlet-side pipe end 5 and to the outlet-side pipe end 6 . A first wear ring 9 and a second wear ring 10 arranged one behind the other in the longitudinal direction of the tube body 2 are accommodated in the inlet-side coupling shoulder 7 . The first sealing ring 9 is made of a wear-resistant and impact-resistant material, for example a ceramic material, chromium carbide casting, martensitic nickel white cast i...

Abstract

A delivery pipe (1) for the transport of solids is described. The delivery pipe (1) has a double-layer pipe body (2) which has in each case a coupling collar (7, 8) at the inlet-side pipe end (5) and at the outlet-side pipe end (6). A first wearing ring (9) and a second wearing ring (10) are provided in the region of the inlet-side coupling collar (7) such that they are arranged one behind another in the longitudinal direction of the pipe body (2). The second wearing ring (10) which lies on the inside has a length (L) which is dimensioned to be greater than or equal to half the internal diameter (ID) of the pipe body (2). As a result, wear phenomena can be reduced in the inlet-side region of the delivery pipe (1) and service life of the delivery pipe (1) can be increased considerably.

Description

technical field [0001] The invention relates to a conveying pipe for conveying solids as characterized in the preamble of claim 1 . Background technique [0002] Such a delivery pipe is considered prior art, for example, by DE 198 09 529 C2. Such a delivery pipe has two successively arranged wear rings in the region of the inlet-side coupling shoulder. [0003] The delivery pipe is widely used in the pipeline of the boom of the automobile concrete pump. The basic criteria for truck-mounted concrete pumps are, in addition to the pump performance or delivery performance, the reach or reach of the distribution boom and a high wear resistance of the pipes. [0004] The delivery pipe is necessarily subject to wear phenomena during operation. In particular, increased wear is determined on the inlet side of the pipe body of the delivery pipe. This wear is not uniformly higher than the wear in the remaining region of the delivery pipe. [0005] It is provided within the scope o...
