Precautions for shutting down a high-temperature condensate pump and replacing the mechanical seal, including pressure relief, etc
Thread Content
Could any technician please explain in detail the precautions for stopping a high-temperature condensate pump, replacing the mechanical seal, and handling pressure release?
Such maintenance is quite common. In my opinion, the key points to pay attention to are two: one is the installation of the mechanical seal, and the other is the adjustment of the clearance during pump installation. It’s a common type of maintenance; when pressure relief occurs, the temperature of the condensate will be high, so be careful not to get burned by it. Removing the pressure gauge by disconnecting the drain valve will ensure thorough pressure relief
