screw vacuum pump of leakage inspection

With the development trend of industrial production, screw vacuum pumps have entered more and more manufacturing industries. In some years, leakage inspection of pump shells has also become a difficult problem, in order to prevent leakage from harming all mechanical equipment in normal production.

Small and micro leaks are difficult to find. The common method is to use a high vacuum pump for leaks that are sensitive to the gas reflection of some weak electrolyte tubes, such as toluene or alcohol. When a needle of medical equipment sprays toluene or alcohol to an abnormal area and the injection leak expires, the hands of the patient are obviously shaken by weak electrolyte. To measure the leakage in this way, it is necessary to wait patiently until the range of the weak electrolyte quality meter is stable, that is, after the vacuum working capacity of the water ring pump is balanced with the leakage rate, spraying can be carried out. This suggestion has been repeated several times and must be missed.

Air leakage mostly occurs at the place where the screw vacuum pump machine equipment is equipped with a water-cooled jacket. No doubts were found during the inspection and exposure, but the following situations occurred: the efficiency of the mechanical pump was significantly reduced, the vacuum gauge range was low, the mechanical equipment oil pump was rapidly emulsified, and the iron base of the vacuum pump chamber was significantly rusted. With the basis of the above standards, there can be obvious internal leakage. Clean the inner chamber first, and then cool the circulating water to see if there are wet spots and if there is water leakage at the wet place.

In case of large leakage, fire prevention can be used. The basic principle of using whirlwind to deflect the fire is to use a vacuum pump first. For example, when you suspect the candles or lighters around you, you will find that the flame deflects towards the leakage, and then you can find the leakage.

The leakage test of screw vacuum pump shall be distinguished from shallow to deep, from small to large, and then the leakage level shall be distinguished, and then symptomatic treatment shall be carried out according to the use situation. The application regulations of mechanical equipment shall be considered.
