Mechanical seal how best to use?

Mechanical seal how best to use? 2020 - 10 - 7 mechanical seal at the time of use, we must pay attention to many problems, so as to make better use mechanical seal, so what is the specific situation? 1, the host before starting, need to check the attached mechanical seal device, cooling and lubrication system is perfect. 2, pipe should be cleaned before starting materials to prevent rust impurities into the sealed cavity. 3, with the hand disc coupling, check whether shaft rotate easily, if the dish is very heavy, need to check the installation dimensions are correct. 4, normal before driving, need a static pressure test, check the mechanical seal face, sealing ring and the sealing effect of sealing end cover, if any problem, check to solve them one by one. 5, the host before starting, we should keep the sealed cavity filled with fluid or sealed by the media, have separate seal system shall be starting, such as cooling water system should also come into circulation. 6, normal before use, first to atmospheric pressure, observe whether the rise of temperature of the sealing parts is normal, ever leak phenomenon. If there is a slight leakage, can run one period of time, the transverse joint more evenly, until leakage was gradually reduced to normal. Such as running 1 - In 3 hours, still don't reduce leakage, need to stop it for checking. 7, working condition of normal operation, the booster heating can slowly, respectively, and pay attention to the temperature rise of end face and the leakage situation, if everything is normal, that can be used in production. When parking, should first stop host, then stop the cooling lubrication system.
