As the title suggests, it is a dry gas seal
If it is a toxic or harmful gas, as long as the gas seal does not leak, it is fine; if there is a leak, protective measures must be taken to ensure that poisoning, fire, or explosion does not occur. It’s fine as long as it’s not a toxic or harmful gas.
It is necessary to shut down the system, release pressure, and disconnect power before starting the disassembly.
Definitely, because you need to remove the thrust pads. The position of the rotor must have changed, resulting in a seal leak
