specific Embodiment approach 1

[0051] 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

[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 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 an air conditioner pipeline repairing method without replacing pipes. A detection device comprises an industrial personal computer, a detection head, a blocking sleeve pipe, a sleeve pipe expulsion device and a detection head moving device, the detection head is connected with the industrial personal computer through a vacuum pipe, the lower end of the detection head is provided with a blocking sleeve pipe sleeve, the sleeve pipe expulsion device is connected to the middle portion of the detection head in a sleeved manner, the upper end of the detection head is further connected with the detection head moving device in a sleeved manner, the repairing device comprises an elastic sleeve pipe, expansionrings and a locking mechanism, two ends of the elastic sleeve pipe are each provided with one expansion ring, the two expansion rings are both connected inside the elastic sleeve pipe in a sleeved manner, and the locking mechanism is clamped on the two expansion rings. By means of the air conditioner pipeline repairing method without replacing the pipes, segmented pressure maintaining test performed on the inner portion of a heat exchanging pipe is realized, so that leakage point positions of the inner portion of the heat exchanging pipe are found out, the two expansion rings are driven by the locking mechanism to fix the elastic sleeve pipe inside the heat exchanging pipe, and repairing on the leakage point positions of the heat exchanging pipe is realized.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to an air-conditioning pipeline repair method without replacing the pipes. 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 The...
