Abstract: In a spin-blast apparatus for cleaning the interior of a pipe, in which abrasive is fed to a rotary blast nozzle caused to travel interiorly along the pipe, and in which the nozzle is mounted on a support conduit journalled for rotation within a non-rotating housing by bearings, the intake end of the support conduit bears against a sealing gasket which is supported by clamping means in such a way as to prevent excessive leakage of abrasive past the gasket. The clamping means is spaced from the end of the housing so as to define therewith a space which is open to atmosphere; thus, any abrasive which leaks past the gasket will fall from the apparatus and will not be forced under air pressure into the bearings.
Abstract translation: 在用于清洁管道内部的旋转喷吹装置中,其中将磨料供给到旋转喷嘴,使其沿管道内部行进,并且其中喷嘴安装在支撑导管上, 通过轴承旋转壳体,支撑导管的进气端承受密封垫圈,密封垫圈由夹紧装置支撑,以防止磨料经过衬垫的过度泄漏。 夹紧装置与壳体的端部间隔开,以便限定出与大气相通的空间; 因此,任何渗透垫圈的研磨剂都会从设备中掉落,并且不会被迫在空气压力下进入轴承。
