The size of mechanical seal load (unit pressure):
For the non-running surface, the impact of the unit pressure on the wear of the metal bellows cartridge mechanical seal is a non-linear relationship, the wear rate (this is used for the rougher, large waviness surface, the actual contact product When it is not too big); for the running-in surface, the wear rate is proportional to the unit pressure.
Similar to 104 custom mechanical seals when the plant load increases, the actual contact area increases, and the friction force also increases. At this time, the temperature of the surface will increase, resulting in accelerated surface destruction. The increase in load will cause the surface to change from slight abrasion to severe abrasion, which occurs approximately when the surface hardness value such as the nominal unit pressure is 1/3.　　412.html,
