Problems solved by technology

[0002] The air conditioner is composed of various parts, among which the heat exchanger is one of them. The heat in the hot air is absorbed and converted into cold air through the heat exchanger, and the heat exchanger is damaged during use, resulting in insufficient air pressure. In order to detect the air pressure of the heat exchanger with a pressure tester, insert the inlet end of the heat exchanger into the outer end of the pressure tube of the test press, and pass the gas into the heat exchanger through the pressure tube to affect the heat exchange. In the prior art, when using a pressure tester to detect the pressure of the air conditioner heat exchanger, the size of the outer end of the pressure tube of the tester is fixed due to the different sizes of the heat exchangers used by air conditioners of different sizes. No change, when testing the pressure of different heat exchangers, it is necessary to use specific adapters to connect them, and increase the time for pressure testing of heat exchangers

Embodiment 1

[0029] as attached figure 1 to attach Image 6 Shown:

[0030] The invention provides a quick pressure test device for an air conditioner heat exchanger, the structure of which includes a body 1, a motor 2, and a pressure test table 3, the bottom of the motor 2 is fixed on the upper surface of the body 1 near the right end, and the pressure test table 3 is located on Motor 2 left.

[0031] The pressure test table 3 includes a table body 31, an air pump 32, a pressure pipe 33, a connecting mechanism 34, and a blocking mechanism 35. The air pump 32 is installed in the middle of the table body 31, and the right end of the pressure pipe 33 is fixed in the middle of the table body 31. On the upper left side, the connecting mechanism 34 is sleeved outside the end of the pressure tube 33 , and the blocking mechanism 35 is set inside the pressure tube 33 near the right end.

Embodiment 2

[0039] as attached Figure 7 to attach Figure 9 Shown:

[0040] Wherein, the blocking mechanism 35 includes an expansion block 351, a clamping ball 352, an air outlet 353, a reset bar 354, a clamping groove 355, and a clamping block 356. The upper and lower surfaces of the clamping ball 352 are embedded and connected with the expansion block 351. The air outlet 353 runs through the surface of both sides of the card ball 352 to divide it into two parts. The upper and lower ends of the reset bar 354 are connected with the upper and lower inner walls of the air outlet 353 near the right end. The card groove 355 is recessed on the left side of the card ball 352 On the side upper surface, the top of the clamping block 356 is integrated with the lower surface on the left side of the clamping ball 352 above, and the clamping groove 355 is movably engaged with the clamping block 356, which can reduce the gap between the clamping balls 352 and can The airflow in the heat exchanger i...

Abstract

The invention discloses a rapid pressure test device for an air conditioner heat exchanger, which structurally comprises a machine body, a motor and a pressure test table, and is characterized in that when different heat exchangers are subjected to pressure test detection, specific adapters need to be adopted for connection, a connecting mechanism is arranged at the outer end of a pressure pipe, and a telescopic ring in the connecting mechanism is in contact with the air inlet end of the heat exchanger; the pressure pipe can stretch out and draw back along with the size of the air inlet end, the gap between the pressure pipe and the air inlet end is reduced, airflow can enter the heat exchanger conveniently, specific adapters needed for pressure testing of different heat exchangers are reduced, and the time for pressure testing of the heat exchangers is shortened; and due to that the heat exchanger contains low-temperature airflow, when air flow is not introduced into the heat exchanger in time during pressure testing of the heat exchanger, the original air flow pressure in the heat exchanger is large, the air flow easily enters the table body from the pressure pipe, and the phenomenon that the interior of the table body is frozen is avoided, the blocking mechanism is arranged in the pressure pipe, the external air flow can be blocked, and the external air flow entering the table body is reduced.
