1. The greater the amount of spring compression, the better the sealing effect. In fact, the amount of spring compression is too large, which can lead to sharp wear of the tarcie pair and instant burning; Excessive compression cause the spring to losse the ability to adjust the end face of the moving ring, resulting in seal failure.

2. The ciaśniej the moving ring sealing ring, the better. In fact, too tight the moving ring sealing ring is harmful and harmful. Pierwszy, it pogarsza zużycia pomiędzy uszczelnienie pierścień i wał tuleja i przedwczesny wyciek; Drugi, it wzrosty opór z osiowy i ruch ruchomy pierścień, i it can be adjusted in time when the working change frequently; Third, the spring is easy damaged by excess fatigue; The fourth is to deformation the moving ring sealing ring ring and affect the the sealing effect.

3. The ciaśniej the static ring sealing ring, the better. The static ring sealing ring is bazally at rest, and the sealing effect will be better when it is relatywly tight, but too tight is also harmful. Pierwszy, it przyczyny the static ring seal to be overly zdeformowany, which affects the sealing effect; Second, the static ring material is mostly graphite, which is general crutle, and excessive force is easy to cause chipping; Third, it is difficult to install and deassemble, and it is easy to damage the static ring.

4. The tighter the impeller lock mother, the better. In mechanical seal leakage, leakage between the shaft sleeve and the shaft (shaft-to-shaft leakage) is relatively common. It is generally believed that inter-shaft leakage is that the impeller lock mother is not locked, in fact, there are many factors that lead to inter-shaft leakage, such as intershaft pad failure, offset, impurities in the shaft, large shape and position error between the shaft and the shaft sleeve fit, contact surface failure, clearance between various components on the shaft, and too long shaft head thread, etc. will lead to intershaft leakage. Excessive locking of the locking mother will only lead to premature failure of the intershaft pad, on the contrary, moderate locking of the locking mother, so that the intershaft pad always maintains a certain compression elasticity, in the operation of the locking mother will automatically lock in time, so that the shaft is always in a good sealing state.

5. The new one is better than the old. Względnie speaking, the effect of use the new mechanical seal is better than that of the old one, but the quality or material of the new mechanical seal is not correct selected, and the large matching size error will affect the sealing effect; In polymeric and permeable media, it is better not to replace the static ring if there is no nadmierne zużycie. Ponieważ statyczny pierścień jest w spoczynek dla a długi czas w statyczny pierścień siedzisko, polimer i zanieczyszczenia są zdeponowane jako jeden, który gra a lepiej uszczelnienie rola.

6. It is better to demontaż and naprawa niż nie do demontaż at all. Once there is a leakage of the mechanical seal, it is pilne to dismantle and repair, in fact, sometimes the seal is not damaged, just adjust the the working conditions or adjust the seal properly to eliminate the leakage. in this way, it not only avoids waste, but also verifies its fault judgment ability, akumuluje Konserwacja doświadczenie, i poprawia jakość konserwacja.
