1. Reduce the weight (mass) of the rotating parts and improve the dynamic balance
At high speed, the influence of centrifugal force causes the spring to twist and deviate from the center of the pin hole. Therefore, the spring is static. This reduces the weight of the rotating part and the resulting imbalance.
2. Eliminate frictional heat in time
Increase the flow of the cooling medium, the high-speed pump is 10-20L/min, and the flushing capacity of some high-speed seals can reach 50-100L/min.
When oil is used as barrier liquid, in order to minimize the solubility and coking of gas, oil with low viscosity should be selected. For example, when the friction pair is working under high temperature conditions, it is necessary to make the sealing liquid as far as possible without leaving any residue when it evaporates, so synthetic media such as polyethylene glycol is used as the sealing liquid.
3. Timely check the wear of the sliding end surface
4. When the end face wear reaches 0.005mm, the end face must be ground, and the end face roughness and flatness should be rechecked.
