Talking About Several Problems That Should Be Paid Attention To in The Maintenance Of Mechanical Seals.
Mar 08, 2022
The consumables will be consumed little by little during the use process. After the mechanical seal ring is used and operated for a period of time, due to the performance degradation and wear of the seal, the mechanical seal ring needs to be properly maintained one or more times. and other work, so as to ensure the normal operation of the mechanical seal ring in the future use or operation.
First of all, for everyone to popularize what is a mechanical seal? The mechanical seal ring structure is one of the more complex mechanical basic components, and is a key component of various pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment.
Talking about the misunderstandings of mechanical seals in maintenance.
1. The greater the spring compression of the mechanical seal, the better the sealing effect of the sealing ring?
In fact, this perception is wrong. If the spring compression of the mechanical seal is too large, it may cause rapid wear of the friction pair or instantaneous burnout of the mechanical seal. If it is excessive compression, the spring will lose the performance of adjusting the end face of the moving ring, which will also lead to the sealing failure of the sealing ring.
2. Is the sealing ring of the moving ring of the mechanical seal locked the tighter the better?
For the moving ring seal of the mechanical seal, the "movement" in the moving ring seal circle means that the seal ring is movable. If the moving ring seal of the mechanical seal ring is too tight, it will be harmful and unhelpful. The wear between a pair of moving ring seals and the shaft sleeve will accelerate the wear and lead to early leakage; secondly, the pressure on the sleeve direction and movement resistance of the moving ring will increase; thirdly, the spring will also be damaged in advance; fourthly, the mechanical seal will be damaged. Deformation, sound sealing effect.
3. Is the tighter the static ring seal the better?
The static ring seals in the mechanical seals are basically in a static state, and the sealing effect will be better relative to the shaft tightness, but if it is too tight, it will cause problems. For example, it directly leads to the deformation, fragmentation, difficulty of assembly, and premature wear of the sealing ring or sealing effect.
