Abstract

The utility model discloses a leak detecting device for a condenser or an evaporator, which comprises a box body. The leak detecting device is characterized in that the box body is simultaneously connected with a main pumping pump (3) and a pre-pumping pump (1), a mass spectrometer (10) is connected on a pipeline communicating the box body with the main pumping pump (3), and valves (5 and 8) are arranged on pipelines which respectively communicating the box body with the main pumping pump (3) and communicating the box body and the pre-pumping pump (1). By adopting the structure, only an evaporator to be detected needs to be placed in the box body, then a vacuum pump is started to pump the box body to be in a vacuum station, an air storage bottle is opened so as to lead air into the evaporator to be detected, if the evaporator leaks air, the air leaks into the box body, and then flows to the mass spectrometer through a pipe, and then the mass spectrometer can generate an alarm signal. By adopting the manner to detect the evaporator, the detection is fast and convenient, the leak detection is correct, and the outgoing quality of the evaporator is ensured.

Description

The leakage detection apparatus of condenser or evaporator

Technical field

The utility model relates to the pick-up unit of a kind of condenser or evaporator, specifically, is a kind of device to condenser or evaporator leak detection.

Background technology

At present, for the manufacturer that produces condenser or evaporator, the assembling quality of evaporator is very important.In the prior art, for the leak detection of condenser or evaporator, generally all adopt manually leak detection one by one, not only speed is slow, and troublesome poeration.So, the leak test plant of a kind of condenser or evaporator has been invented by my unit in 2009, this equipment has been applied for patent to State Intellectual Property Office, and authorized patent right, the patent No. is: 200920119639.6, denomination of invention is " leak test plant of condenser or evaporator ", this patent disclosure following content: the leak test plant of a kind of condenser or evaporator, it is characterized in that: described condenser or evaporator leak test plant are provided with at least one leak detection circuit, every the leak detection circuit includes the gas filling valve that measured piece is inflated, be provided with pressure transducer and air release between gas filling valve outlet and the measured piece, pressure transducer and pressure digital displaying meter are electrically connected, each bar leak detection circuit is arranged in parallel, the inflow point of each bar leak detection circuit is provided with a total bleed pressure sensor, and total bleed pressure sensor is electrically connected with total bleed pressure digital displaying meter.The leak test plant of this structure, though solve the problem of artificial single detection to a certain extent, because instrument is too much, damage easily, and be difficult to maintenance after damaging, the process of hunting leak can not be very accurate simultaneously.

Summary of the invention

In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides a kind of simple in structure, the leakage detection apparatus of hunt leak accurate condenser or evaporator.

For this reason, the utility model adopts following technical scheme to realize: the leakage detection apparatus of a kind of condenser or evaporator, has casing, it is characterized in that described casing is communicated with main take out pump and forepump simultaneously, described connection master takes out on the pipeline of pump and connects mass spectrometer, and is equipped with valve being communicated with on the main pipeline of taking out pump and forepump.

Described casing comprises lid and body, and described lid is hinged on the body, on the described cover cap after, the inner chamber of casing forms airtight space.

Described casing is taken out pump by lobe pump with described master and is communicated with.

In the utility model, as long as completely charged condenser or evaporator are placed in the casing, utilize each pump that casing is evacuated then, when condenser or evaporator have gas leakage, because first vacuum pump and lobe pump sum that mass spectrometric draft is compared are also big, so the gas that spills is just by mass spectrometer, after mass spectrometer runs into gas, just can produce alerting signal, come to determine the quality of detected condenser or evaporator according to this, have leak detection accurately, simply and easily characteristics.

Description of drawings

Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.

Fig. 1 is a structural drawing of the present utility model.

Embodiment

With reference to accompanying drawing, the leakage detection apparatus of this condenser or evaporator has casing, described casing is communicated with main take out pump 3 and forepump 2 simultaneously by pipeline 7,4, after wherein forepump 1 connected gas-holder 2, again by pipeline 7 connect boxes, described connection master took out on the pipeline 4 of pump 3 and connects mass spectrometer 10; Described casing comprises lid 9 and body 11, and described lid 9 is hinged on the body 11, and after described lid 9 covered, the inner chamber of casing formed airtight space; Described casing is taken out pump 3 by lobe pump 6 with described master and is communicated with.Wherein the master takes out the outlet at bottom that pump 3 is connected lobe pump 6.Simultaneously be provided with valve 5,8 with main taking out on the pipeline 7,4 that pump 3 and forepump 1 be communicated with.When using the utility model, forepump 1 is at first worked, make forepump 1 that the gas in the gas-holder 2 is extracted out, when the air pressure in the gas-holder 2 reaches about 1000Pa, the condenser or the evaporator that are filled with helium are placed in the casing, after covering lid 9, open and take out valve 5 in advance and since open take out valve 5 in advance before, the pressure of gas-holder 2 is lower, so the gas in casing and the pipeline just leads to gas-holder 2, because working on of forepump 1, so, the gas in pipeline and the casing is taken out in advance, when the atmospheric pressure in casing and the pipeline acquires a certain degree, close and take out valve 5 in advance, open the main valve 8 of taking out, the main simultaneously pump 3 of taking out is worked, once more the gas in pipeline and the casing is exhausted, casing is formed vacuum.At this moment, if there are gas leakage in detected condenser or evaporator, helium just can leak to casing, because the draft of mass spectrometer 10 is also bigger than the draft sum that the master takes out pump and lobe pump 6, therefore, one has helium to spill, just can leak to mass spectrometer 10, after mass spectrometer 10 detects helium, just can produce alerting signal, this just illustrates that there are gas leak phenomenon in detected condenser or evaporator, is product off quality.If mass spectrometer 10, illustrates then that detected condenser or evaporator belong to specification product without any sound.This leakage detection apparatus, it is simple in structure, and leak detection simultaneously is accurately convenient, and the manufacturer for producing condenser and evaporator has positive result of use.

Claims (3)

1. the leakage detection apparatus of condenser or evaporator, has casing, it is characterized in that described casing is communicated with main take out pump (3) and forepump (1) simultaneously, described connection master takes out on the pipeline of pump (3) and connects mass spectrometer (10), and be equipped with valve (5,8) being communicated with on the main pipeline of taking out pump (3) and forepump (1).
