Description

Technical Field

[0001] The invention relates to the technical field of pressure vessel leakage detection, in particular to a boiler pressure vessel leakage detection device and a detection method. Background Art

[0002] The original meaning of pot refers to a container for holding water heated on fire, and furnace refers to a place where fuel is burned. A boiler consists of two parts: a pot and a furnace. The hot water or steam produced in a boiler can directly provide the required heat energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small number of applications in industrial production. A boiler that produces steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises.

[0003] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument. It can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece quickly, conveniently, non-destructively and accurately. It is widely used in boiler pressure vessel leakage detection. Due to the large size of the boiler, when conducting leakage detection on the boiler, the staff needs to hold the ultrasonic flaw detector and climb up and down to conduct the detection. Due to the large amount of exercise and the heat generated by the ultrasonic flaw detector itself, the staff's fingers are prone to sweating, which makes it easy for them to slip and lose their grip on the ultrasonic flaw detector, causing the ultrasonic flaw detector to be injured or broken.
