Fault Analysis And Countermeasure Of Common Centrifugal Pump Mechanical Seal Device

With the rapid development of the domestic manufacturing industry in Chinese steps, the use of mechanical seals in the reality is more and more widely. At the same time, amount of capital required more and more.In this context, some related problem arises, the project mainly covers the following points: one is the method of repair funds, which control; two is the anti penetration which control measures; three is the life of the mechanical seal itself how to prolong the. Therefore, this paper will be based on the specific research on related topics. This paper will use 5 chapters to more detailed content of this subject. The principle of the first chapter of this paper on the basis of the mechanical seal and the relevant requirements. The second chapter explains the failure of mechanical seal of a root specific expression and fault. In this section, this paper will do the following aspects: one is involved in the mechanical seal leakage fault and intrinsic reason; two is the heat fault involved in mechanical seal and intrinsic reason; three is the vibration fault involved in mechanical seal and intrinsic reason. The third chapter describes some measures of the fault. In addition, this paper also explains the following measures: one is to meet the pump vibration which is available measures; two is to meet the pump shaft clearance is available measures; three is to increase the irrigation system can be necessary in mechanical seals. The fourth chapter explains the method of corrosion protection seal relates to the damage and the corresponding. In this section, this paper will do the following points: 1 is a metal ring to corrosion; two is the sealing ring to corrosion; three non metal ring to corrosion protection method; four is the corresponding. The fifth chapter explains the source of leakage treatment of centrifugal pump and the corresponding.In the use of these methods of analysis, this paper will research achievements are huge in the following aspects: first is the enhancement of the mechanical seal of protection; two is the compression of the capital investment required; three is in the mechanical seal, no matter is the vibration fault or leakage has been effectively controlled.
