specific Embodiment approach 1

[0051] to combine figure 1 with 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 interior of the detection head 2 is provided with an axial through hole, and the upper end of the through hole is connected to the industrial computer 1 through a vacuum tube. The lower end of the detection head 2 is provided with a cup-shaped structure with a gradually increasing outer diameter. 3 is socketed on the cup-shaped structure, the casing squeezing device 4 is socketed in the middle of the detection head 2, and the lower end of the casing squeezing device 4 is fixedly connected with the upper end of the blocking casing 3, so that The upper end of the detection head 2 is also sleeved with a detection head movement device 5; the plugging sleeve 3 is squeezed by the sleeve extrusion ...

specific Embodiment approach 2

[0056] 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

[0058] 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 casing, the plugging sleeve 3, the sleeve extrusion device 4 and the probe moving device 5 are all arranged in the casing; the casing provides protection to the internal components to prevent the device from being damaged during use.

Abstract

The invention relates to the technical field of central air-conditioning, in particular to a central air-conditioning heat exchange tube leakage point detecting device. The central air-conditioning heat exchange tube leakage point detecting device comprises: an industrial personal computer, a detecting head, a plugging casing pipe, a casing pipe extruding device and a probe moving device; the detecting head is connected to the industrial personal computer through a vacuum tube; the lower end of the detecting head has a plugging casing pipe sleeve; the center of the detecting head is sleeved with the casing pipe extruding device; the probe moving device sleeves the upper end of the detecting head; a repairing device comprises an elastic sleeve, expansion rings and a locking mechanism, wherein each of both ends of the elastic sleeve is provided with an expansion ring, the two expansion rings are sleeved inside the elastic sleeve, and the locking mechanism is clamped on the two expansionrings; segmentation pressure maintaining test of the interior of the heat exchange tube can be achieved, the position of a leak point inside the heat exchange tube can be found; the locking mechanismdrives the two expansion rings to fix the elastic sleeve inside the heat exchange tube, and then the leak point of the heat exchange point is repaired.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a leak detection device for heat exchange tubes of central air conditioning. Background technique [0002] The central air conditioner is an air conditioner that controls different rooms by connecting multiple terminals with wind, fire, cold and hot water pipes to achieve the purpose of indoor air conditioning. The host has a variety of cold storage methods, and the lithium bromide refrigeration unit uses heat as power. The advantages of small vibration and low noise occupy an important position in the host market. The lithium bromide refrigerator uses the absorption and release of water vapor from the lithium bromide aqueous solution at different temperatures to achieve refrigeration. This cycle needs to use external heat sources to achieve refrigeration. Commonly used heat sources are steam, hot water, gas, fuel oil, etc. Lithium bromide refrigerators have many...
