As a mechanical equipment used in sewage treatment, submersible mixers have very strict requirements for mechanical seals . However,misunderstandings often occur about mechanical seals. For example:
1. The tighter the rotary face is, the better.Get more news about Submersible Pump Seals,you can vist our website!
In fact, a too tight rotary face is harmful and useless. First,it is to aggravate the wear between the sealing ring and the shaft sleeve, thus causing leakage prematurely; Second,it is to increase the resistance of the axial adjustment and movement of the rotary face, which cannot be adjusted in time when the working conditions change frequently; Third,the spring is easily damaged due to excessive fatigue; Last,it deforms the sealing ring and affects the sealing effect of the rotary face.
2. The tighter the stationary seat is, the better.
The stationary seat is basically in a static state, and the sealing effect will be better if it is relatively tight, but it is also harmful if too tight. First,the sealing ring will be deformed, which affects the sealing effect; second,if made of graphite, the sealing ring is generally so brittle that excessive stress can easily cause cracks; third, it is difficult to install and disassemble because the stationary seat is easily damaged.
3. The larger the spring compression, the better the sealing effect of the mechanical seal.
Excessive compression of the spring can cause rapid wear of the friction pair and instant burnout; excessive compression makes the spring lose its ability to adjust the end face of the rotary face, resulting in seal failure.
