specific Embodiment approach 1

[0027] Specific implementation mode one: combine Figure 1 to Figure 15 and Figure 19 Describe this embodiment, an array type heat exchange tube wall thickness on-line ultrasonic monitoring device in this embodiment, the on-line ultrasonic monitoring device includes an ultrasonic thickness measuring device, a fastening positioning component and a couplant automatic circulation component, the ultrasonic thickness measuring device Including probe 1, probe 1 includes connecting pipeline 1-1, probe main body 1-2, ferrule 1-3 and probe delay block 1-4, connecting pipeline 1-1, probe main body 1-2, ferrule 1-3 Both the probe delay block 1-4 are of cylindrical structure, the probe main body 1-2 is vertically arranged, the outer circle of the upper part of the probe main body 1-2 is horizontally opened with a pipeline socket, and one end of the connecting pipeline 1-1 is inserted into the probe main body 1- 2, the probe delay block 1-4 is fixed on the lower end surface of the probe ...

specific Embodiment approach 2

[0032] Specific implementation mode two: combination Figure 7 , Figure 10 , Figure 12 and Figure 13 To illustrate this embodiment, the accommodating cavity 4 of this embodiment includes a first fitting groove 4-1 and a second fitting groove 4-2 arranged coaxially in the vertical direction, the first fitting groove 4-1 and the second fitting groove 4-2 The ferrule 1-3 is matched, the second assembly groove 4-2 is matched with the probe body 1-2, the first assembly groove 4-1 is located above the cylindrical through hole 2-4 and is connected with the cylindrical through hole 2-4 In communication, one side of the second assembly groove 4-2 offers a third assembly groove 4-3 along the horizontal direction, and one end of the third assembly groove 4-3 communicates with the second assembly groove 4-2, and the third assembly groove 4 -3 matches the connecting line 1-1. In this way, the third assembly groove 4-3 on the upper part is used for leading out the connecting pipeline...

specific Embodiment approach 3

[0033] Specific implementation mode three: combination figure 2 To illustrate this embodiment, the ultrasonic thickness measuring device of this embodiment also includes a reed 1-5 and a circular gasket 1-6. There are circular pads 1-6 and reeds 1-5. In this way, the fixing of the probe 1 in the vertical direction is realized by using the pressing device of the reed 1-5. The second assembly groove 4-2 on the top of the first separate entity 2-1 and the second separate entity 2-2 is used to provide the vertical direction pre-tightening force to the reed 1-5, and a thinner joint is connected below the reed 1-5. Circular spacers 1-6 with a thickness of 0.5 mm are used to prevent the direct contact area between the reeds 1-5 and the top of the probe from being too small, and the friction force is small to cause lateral displacement due to sliding. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an array type heat exchange tube wall thickness online ultrasonic monitoring device, relates to the technical field of online measurement of the wall thickness of a heat exchange tube of a radiator, and solves the problem that the existing liquid-cooling small-radius pipeline wall thickness detection adopts manual detection, and the labor intensity is high, the efficiency is low, the environment is wet and hot, the precision is low, and the information management and maintenance are not facilitated. The array type heat exchange tube wall thickness online ultrasonic monitoring device comprises an ultrasonic thickness measurement device, a fastening position assembly and an automatic coupling agent circulation assembly, wherein the fastening position assembly enablesa probe to be in close contact with a heat exchange tube; the automatic coupling agent circulation assembly ensures that the air between the probe and the heat exchange tube is emptied, and corrosionto the heat exchange tube is reduced to the maximum extent; the probe of the ultrasonic thickness measurement device is a high-frequency probe, and can continuously send out and receive ultrasonic waves; the measuring method adopts the principle of a pulse echo method, the measured data is returned to an external host to be monitored in real time, and the external host processes the data. The device is used for online ultrasonic monitoring of the wall thickness of the heat exchange tube.

Description

technical field [0001] The invention relates to the technical field of on-line measurement of the wall thickness of radiator heat exchange tubes, in particular to an on-line ultrasonic monitoring device for array heat exchange tube wall thickness. Background technique [0002] The hydropower station drives the rotor to rotate through the downstream of the river, that is, the gravitational potential energy is converted into mechanical energy and then converted into electrical energy to power generation. Due to the frictional resistance of the rotor during rotation, the huge rotor generates huge heat, which increases the temperature of the rotor and the surrounding air. High temperature will not only lead to unstable operation of the system, but also shorten the service life of the unit, and may even burn some parts, so a radiator is needed to reduce its temperature. The working mode of the heat exchange tube is liquid cooling, the coolant flows in the heat exchange pipe of th...
