specific Embodiment approach 1

[0055] combine figure 1 and figure 2 As shown, a central air-conditioning heat exchange tube leakage detection device disclosed in this embodiment includes: an industrial computer 1, a detection head 2, a plugging sleeve 3, a sleeve extrusion device 4 and a probe moving device 5. The inside of the detection head 2 is provided with an axial through hole, the upper end of the through hole is connected to the industrial computer 1 through a vacuum tube, and the lower end of the detection head 2 is provided with a cup-shaped structure with a gradually increasing outer diameter. The plugging sleeve 3 Sleeved on the cup-shaped structure, the sleeve extrusion device 4 is sleeved in the middle of the detection head 2, and the lower end of the sleeve extrusion device 4 is fixedly connected with the upper end of the blocking sleeve 3, the The upper end of the detection head 2 is also sleeved with a measuring head movement device 5; the plugging sleeve 3 is squeezed by the casing extru...

specific Embodiment approach 2

[0060] This embodiment is based on the specific implementation mode 1, the difference is that the industrial computer 1 includes: a vacuum pump, a pressure gauge and a valve, the vacuum pump is connected to the vacuum tube, the pressure gauge is set on the vacuum tube, and the valve is set at the pressure On the vacuum tube between the gauge and the vacuum pump; after the vacuum pump forms a negative pressure environment, close the valve to maintain the pressure, and observe the pressure change through the pressure gauge to realize the vacuum pressure maintaining experiment.

specific Embodiment approach 3

[0062] This embodiment is based on the specific implementation mode 1, the difference is that the outer side of the detection head 2 is also provided with a housing 21, and the sealing sleeve 3, the sleeve extrusion device 4 and the movement of the measuring head The devices 5 are all arranged in the casing 21; the casing provides protection for internal components to prevent the devices from being damaged during use.

Abstract

The invention relates to the technical field of central air conditioners, in particular to a detection head movement stabilizing method and a leakage point detection method with the same. A detectiondevice comprises an industrial personal computer, a detection head, a plugging sleeve, a sleeve extrusion device and a detection head movement device, the detection head is connected with the industrial personal computer through a vacuum tube, a plugging sleeve sleeve is arranged at the lower end of the detection head, the sleeve extrusion device is sleeved in the middle of the detection head, theupper end of the detection head is further sleeved with a detection head movement device; and an repairing device comprises an elastic sleeve, expansion rings and a locking mechanism, the two ends ofthe elastic sleeve are each provided with one expansion ring, the two expansion rings are connected in the inner part of the elastic sleeve in a sleeved mode, and the locking mechanism is clamped onthe two expansion rings. According to the detection head movement stabilizing method and the leakage point detection method with the same, a segmented pressure maintaining experiment is carried out onthe inner part of a heat exchange tube, so that a leakage point position in the inner part of the heat exchange tube is found out; and the two expansion rings are driven by the locking mechanism to fix the elastic sleeve in the inner part of the heat exchange tube, so that repairing the leakage point of the heat exchange tube is realized.
