When it comes to the internal leakage of vacuum pump unit, we should pay attention to it mostly, that is, it will happen on a device with water cooling jacket. When it comes to the internal leakage of the vacuum pump unit, in fact, we found no doubt during the inspection of the external leakage, but the pumping speed of the mechanical pump is obviously lower, and the indication value of the vacuum gauge is relatively low or the mechanical pump oil emulsifies quickly.

如果發(fā)現(xiàn)真空泵機組中的真空室內的鐵基零部件上會明顯銹蝕的現(xiàn)象的時候。基本可以確定它發(fā)生了內漏的現(xiàn)象。這個時候，要注意應該要先把內壁進行清理干凈，接下來，要通冷卻水，看它有沒有無濕潤點，它的濕潤處就是它的漏點。

If it is found that the iron-based parts in the vacuum chamber of the vacuum pump unit will be obviously rusted. It can be determined that there is leakage. At this time, it should be noted that the inner wall should be cleaned first, and then, the cooling water should be filled to see if it has any wetting point. The wet part is the leakage point.

真空泵機組小漏和微其實也就是比較難查，常用的方法是要利用它在高真空狀態(tài)下電離管對于某些氣體反應敏感來進行檢漏。比較常見是指丙酮或者是乙醇，可以用醫(yī)用注射器直接的就向可疑的地方進行噴射丙酮或者是乙醇，當噴到漏點的時候，我們就會發(fā)現(xiàn)對于電離計的指針上會有比較明顯的擺動。

In fact, it is difficult to check the small leakage and micro leakage of the vacuum pump unit. The common method is to use the ionization tube sensitive to some gases in high vacuum state to detect the leakage. It is common to refer to acetone or ethanol, which can be directly sprayed to the suspicious place with a medical syringe. When it reaches the leakage point, we will find that the pointer of the ionization meter will swing obviously.

用這種方法對真空泵機組進行檢漏一定的要有耐心，一定要等到電離計的示值穩(wěn)定了之后，就這個方面來講的話，我們就是會發(fā)現(xiàn)它在抽氣能力與漏率上其實也就是會實現(xiàn)了平衡，接著可以實現(xiàn)噴射。

If we use this method to detect the leakage of the vacuum pump unit, we must be patient and wait until the indication value of the ionization meter is stable. In this respect, we will find that the balance between the pumping capacity and leakage rate can be realized, and then the injection can be realized.

對于真空泵機組較大的漏點，可以直接的就用火焰法，利用氣流來直接的就使火焰進行偏離的原理，要注意應該先要抽上真空，接下來的話，要用蠟燭或者是打火機在真空泵機組可疑點附近進行逐步查尋。

For the larger leakage point of vacuum pump unit, the flame method can be directly used, and the principle of using air flow to directly make the flame deviate. It should be noted that the vacuum should be pumped first, and then, the candle or lighter should be used to gradually search the suspicious point of the vacuum pump unit.
