Dear experts, I am using isopropanol and a mechanical pump for circulation; the reaction temperature is around 130°C, with a pressure of 0.4–0.5 MPa. Leaks start to occur once the temperature reaches around 80°C. Fluororubber is used for the sealing rings, and sealing is achieved by compressing the spring ends. Hope the expert is online to answer
I didn’t quite understand. Are you referring to a shaft seal leak? Is it in a power-off state? This requires making appropriate adjustments to the installation depending on the specific circumstances
