摘要： A novel automated ultrasonic examination system for heat transfer tubes (2) in a boiler is disclosed herein, which makes it possible to perform ultrasonic examination from the inside of the heat transfer tubes (2) without necessitating removal of scale from the outer surfaces of the boiler tubes (2) by polishing nor necessitating measurements in restricted places where manual measurements are difficult or impossible. The disclosed novel system comprises an insert tube (1) adapted to be inserted into a cylindrical header (3) to which one end of the heat transfer tubes (2) are connected, an insert tube moving device (5) for moving the insert tube (1) in the axial direction of the header (3) and revolving it about its own axis, an ejection nozzle (6) provided on the insert tube (1), a water pump for feeding pressurized water to the ejection nozzle (6), a cable (13) adapted to be inserted from the ejection nozzle (6) into the heat transfer tube (2) as passed through the insert tube (1) by the pressurized water fed from the water pump, a cable (13) accommodation tank (10a) for accommodating the cable (13), a revolving submerged ultrasonic probe (14) mounted at the tip end of the cable (13), and an ultrasonic examination unit (21) for processing signals sent from the probe (14) and displaying the results of examination. Preferably, means for detecting a length of the cable (13) inserted into the heat transfer tube (2), is provided in the automated ultrasonic examination system.
摘要翻译：本文公开了一种用于锅炉中的传热管（2）的新型自动超声波检查系统，其使得可以从传热管（2）的内部进行超声波检查，而不需要从外部表面去除垢锅炉管（2）通过抛光也不需要在手动测量困难或不可能的限制地方进行测量。所公开的新颖系统包括适于插入到传热管（2）的一端连接到的圆柱形集管（3）中的插入管（1），用于移动插入管的插入管移动装置（5）（1）在集管（3）的轴向上并围绕其自身的轴线旋转，设置在插入管（1）上的喷嘴（6），用于向喷嘴（6）供给加压水的水泵，，适于通过从水泵供给的加压水通过插入管（1）从喷嘴（6）插入到传热管（2）中的电缆（13），电缆（13）的容纳用于容纳电缆（13）的容器（10a），安装在电缆（13）的末端的旋转浸没式超声波探头（14），以及用于处理从探头（14）发送的信号的超声波检查单元（21）并显示检查结果。优选地，在自动超声波检查系统中提供用于检测插入到传热管（2）中的电缆（13）的长度的装置。

摘要： An improved automatic tube circumference scanning apparatus for automatically performing inspections, repairs and other works for a group of tubes arrayed in a narrow space as directed in the horizontal directions is disclosed. The improvements reside in that the apparatus is composed of an upper support/traverse section (7) mounted on an upper tube in the group of tubes so as to be able to travel along a tube axis and to stop and grip said upper tube, a lower support/traverse section (11) mounted on a lower tube so as to be able to travel, stop and grip said lower tube, a flexible rail (8) extended vertically between the upper and lower support/traverse sections and fixed thereto, and a probe scanning section (16) mounted on the flexible rail (8) so as to be able to move up and down, which grips any arbitrary tube between the aforementioned upper and lower tubes for making a probe scan around the same tube.
