換熱器試漏槍的特點(diǎn)主要有以下幾方面：

The characteristics of the heat exchanger test gun are mainly in the following aspects:

　　l）預(yù)備時(shí)間短。將試漏槍的各部件組裝好，連接足夠長度的高壓軟管，并引入打壓介質(zhì)，打壓介質(zhì)采用裝置區(qū)的消防水或工廠風(fēng)。與此同時(shí)，將換熱器封頭拆下，就可以進(jìn)人管束試漏狀態(tài)。

1) short preparation time. The leakage testing gun parts assembled, enough length of the high pressure hose connection, and the introduction of medium pressure, pressure medium is adopted as the unit area of the fire or the factory wind. At the same time, the head of the heat exchanger can be removed, and it can be put into the test and leakage state of the tube bundle.

　　2）操作過程簡便。以單管試漏為例，兩桿組裝好的試漏槍分別插入換熱器一根管束的兩端并壓緊，將引人介質(zhì)的槍閥打開，關(guān)閉另?xiàng)U槍閥，當(dāng)壓力升到規(guī)定值后，立即關(guān)閉引入介質(zhì)槍閥，若兩表壓不變，則無泄漏；若兩表壓均降，則管束泄漏；一若引人介質(zhì)端表壓不降，另端表壓為零，則管堵?？傊?，根據(jù)兩桿槍壓力表讀數(shù)的情況，可以判斷出管束是否泄漏和堵塞。

2) the operation process is simple and convenient. On the single tube leakage, for example, two rod assembly good test leakage gun are respectively inserted into the heat exchanger a root bundle at both ends and pressing, which will lead medium gun valve open, the other gun valve is closed, when the pressure rose to the specified value, immediately shut down into the media gun valve, if two gauge invariant, no leakage; if two gauge was decreased and then bundle leakage; a lead end medium gauge does not fall, on the other end of the gauge to zero pipe plugging. In short, according to the two gun pressure gauge readings, you can determine whether the leakage and blockage of the tube.

　　3）操作時(shí)間具有可縮性。潤滑油代理根據(jù)換熱器檢修工期的長短要求，可選擇單管或多管試漏槍，也可選擇兩套以上試漏槍同時(shí)進(jìn)行試漏。按每根管束試漏檢驗(yàn)時(shí)間為205，檢驗(yàn)管束時(shí)，單管試漏槍需操作5.5h，多管試漏槍（3個(gè)槍頭）僅需操作1.5h。

3) the operation time has the ability to shrink. Lubricating agent according to the change of the length of the heat exchanger maintenance schedule requirements, choose single - or multiple leakage testing gun, can also choose two or more leakage testing gun and leakage test. According to each pipe bundle leakage inspection time for 205, test tube bundles, single tube test leakage gun to 5.5 hours of operation, multi try leakage gun (three gun head) only 1.5 hours operation.

　　4）適用范圍廣。陶瓷纖維紙?jiān)嚶尩氖褂貌皇墉h(huán)境溫度及其他外界因素的影響。使用過程中可以分別引入氣態(tài)或液態(tài)打壓介質(zhì)，適用于不同介質(zhì)類型的各種換熱器。

4) a wide range of application. The use of ceramic fiber paper test gun is not affected by ambient temperature and other external factors. Gas or liquid pressure medium can be introduced into the use process, which is suitable for various kinds of heat exchangers with different media types.

　　5）科學(xué)性強(qiáng)槍頭與管束端口之間采用錐型膠塞連接，可壓縮性強(qiáng)、密封性好。

5) the cone type rubber plug connection is adopted between the scientific strong gun head and the tube bundle port, which can be compressed and has good sealing performance.

　　一般管束試漏壓力均在0.5MPa以下，人工持槍推壓便可進(jìn)行試驗(yàn)。若有特殊要求試驗(yàn)壓力超過0.5MPa時(shí)，可制做配套夾具固定在換熱器管板上，推壓槍頭進(jìn)行試驗(yàn)。單管或多管試漏時(shí)，因打壓介質(zhì)充填量小，若管束有漏點(diǎn)，易于從壓力表上快速顯現(xiàn)出壓降。

General tube bundle test pressure is below 0.5MPa, the artificial gun can be carried out on the test. If you have special requirements, test pressure exceeds 0.5MPa, the matching manufacture fixture is fixed on the heat exchanger tube plate, pushing pressing head test. Single - or multiple leakage test, by suppressing media filling quantity is small, if the tube bundle leakage, easy to from the pressure gauge on the fast show pressure drop.

6）試漏槍加工制作簡便、成本低經(jīng)過對管束試漏槍的研制，并在實(shí)踐中應(yīng)用，使用效果良好，達(dá)到了對換熱器管束的打壓試漏目的。與現(xiàn)有技術(shù)相比，具有簡便易行、試驗(yàn)成本低、適用性強(qiáng)等特點(diǎn)，極具推廣價(jià)值，是換熱器管束打壓試驗(yàn)的理想工具?！?/p>

6) leakage testing gun processing has the advantages of simple manufacture, low cost after the development of tube bundle leakage testing gun and in practical applications, and good use effect to the heat exchanger（www.hreqi.com） tube bundle leakage test with pressure to. Compared with the prior art, the method has the advantages of simple and easy operation, low cost and strong applicability, and is an ideal tool for the pressure test of the heat exchanger tube bundle.
