With reference to shown in figure 1, a kind of structure of the leakage detection apparatus of the pipe-line system of the air conditioner provided for the embodiment of the present application
Schematic diagram, wherein, leakage detection apparatus includes:
Seal box 100, the seal box 100 are used to place the air conditioner 500, wherein, the pipeline of the air conditioner 500
Refrigerant is filled with system;
The pump-line 200 connected with the seal box 100;
The vacuum extractor 300 being connected with the pump-line 200;
And detection means 400, the detection means 400 include the probe 401 being arranged in the pump-line 200,
The detection means 400 is used for detecting in the pump-line 200 whether have the refrigerant.
Specifically, the leakage detection apparatus of the pipe-line system for the air conditioner that the embodiment of the present application provides, is examined to air conditioner
During drain process, after air conditioner is positioned in seal box first, seal box is sealed;Then by vacuum extractor unlatching to close
Joint sealing carries out vacuumize process;And detection means opens work while seal box seals, pump-line is detected
Whether the presence of refrigerant is had, wherein, when having refrigerant in detection means detection pump-line, leak detection finishes, and shows this
The pipe-line system of air conditioner is unqualified;Or detection means has system in seal box to be not detected by during vacuum in pump-line
During cryogen, detection finishes, and shows that the pipe-line system of the air conditioner is qualified.
For the leak detection process that becomes more meticulous, and the size of the small opening of pipe-line system, the application can be judged during leak detection
Embodiment can be hunted leak stage by stage, i.e. leakage detection apparatus is embodied as vacuum extractor treatment by stages mistake stage by stage
Cheng Wei:The vacuum extractor is used to carry out vacuumize process to the seal box stage by stage;
Wherein, there is the refrigerant in the detection means detection pump-line at any one stage, or
Person's detection means at all stages is detected when not having the refrigerant in the pump-line, the leakage detection apparatus
Complete leak detection process.
Specifically, the leakage detection apparatus that the embodiment of the present application provides can divide three phases to be hunted leak, wherein, it is described to take out very
Empty device is used to divide three phases to carry out vacuumize process to the seal box, wherein, the three phases are followed successively by initial rank
Section, interstage and terminal stage;
Wherein, the vacuum extractor is used to make in the starting stage air pressure in the seal box to be the first default gas
Pressure;The vacuum extractor is used to make air pressure in the seal box be the second preset pressure at the interstage;And institute
Stating vacuum extractor is used to make in the terminal stage air pressure in the seal box to be the 3rd preset pressure, and described second is default
Air pressure is less than first preset pressure and is more than the 3rd preset pressure.
Three phases are described in detail below in conjunction with the accompanying drawings, wherein, described the first of the embodiment of the present application offer is pre-
If air pressure can be atmospheric pressure.With reference to shown in figure 2, a kind of stream of the leak detection process for leakage detection apparatus that the embodiment of the present application provides
Cheng Tu, wherein, leak detection process includes:
In starting stage S1, after air conditioner is positioned over into seal box, seal box is sealed, at the same open detection fill
Put whether detection pump-line has refrigerant, if so, then completing leak detection process S4;If no, into interstage S2.
In the starting stage, actual vacuum extractor is the initial standby stage, now, treats the moment for sealing seal box,
Its internal air pressure is equivalent to atmospheric pressure, typically about 0.1MPa, i.e. the air pressure P1 in seal box is atmospheric pressure;And by
Refrigerant has been inflated in the pipe-line system of air conditioner, thus the pressure P0 in the pipe-line system of air conditioner is generally 1.5Mpa
More than.Therefore, in the starting stage, if pipe-line system has small opening, refrigerant meeting through hole small opening quickly fills with seal box, then
Into in pump-line, and then the probe sensing for the detection means being placed in pump-line, to detect the pipe of air conditioner
There is small opening in road system, complete leak detection process.Wherein, detection means can be integrated with display module and/or alarm module, to carry
Show that testing staff's pipe-line system has small opening.And further detection means can also show when with display module and take out
The concentration of feed channel inner refrigerant, and calculate according to this leak rate of small opening and shown.
In the starting stage, if detection means, which is not detected in pump-line, has refrigerant, illustrate pipe-line system
Small opening it is smaller, or, illustrate that pipe-line system does not have small opening, this needed further to be detected into next stage.
In interstage S2, open vacuum extractor vacuumize process is carried out to seal box, make the air pressure in seal box be
Second preset pressure, while whether detection means detection pump-line has refrigerant, if so, then completing leak detection process S4;If not yet
Have, then into terminal stage S3.
At the interstage, vacuum extractor is opened to carry out vacuumize process to seal box, when the pipeline system of air conditioner
When system has smaller small opening, the amount in leakage of refrigerant to seal box is less, and concentration is relatively low.It is additionally, since the molecule of refrigerant
Quality is big compared with the molecular mass of air, and refrigerant molecules diffusion velocity is slow, and second is evacuated to seal box in vacuum extractor
During before preset pressure, refrigerant can not be sensed by the probe of detection means;But with the pressure in seal box
Constantly reduce, air concentration constantly reduces, and refrigerant molecules diffusion velocity is accelerated, and when the pressure in seal box, to be reduced to second pre-
If during air pressure P2, refrigerant is sensed by the probe of detection means, and then completes leak detection process.
At the interstage, if detection means, which is not detected in pump-line, has refrigerant, illustrate pipe-line system
Small opening it is more small, or, illustrate that pipe-line system does not have small opening, this needed further to be detected into next stage.
Continue to carry out vacuumize process to seal box in terminal stage S3, vacuum extractor, make the air pressure in seal box be
3rd preset pressure, while whether detection means detection pump-line has refrigerant, if so, then completing leak detection process S4;If not yet
Have, then complete leak detection process S4, show pipe-line system without small opening.
Entering terminal stage after the interstage, vacuum extractor continues to carry out vacuumize process to seal box, when
When air pressure in seal box is reduced to three preset pressures, and detection means is detected in pump-line when having refrigerant, then complete
Into leak detection process, showing the pipe-line system of air conditioner has small small opening;Or when detection means is detected in pump-line
It is same to complete leak detection process when there is no refrigerant with refrigerant, and illustrate that pipe-line system does not have small opening.
Further, with reference to shown in figure 3, the leak detection dress of the pipe-line system for another air conditioner that the embodiment of the present application provides
The structural representation put, the leakage detection apparatus that the embodiment of the present application provides also include:The report being connected with the detection means 400
Alarm device 600;
Wherein, the warning device 600 be used for the detection means 400 detect in the pump-line 200 have it is described
Alarm is sent during refrigerant.In the embodiment of the application one, the warning device can be:Acoustic alarm device, light alarm device
Or acoustic-optic alarm.
