Leakage at the shaft seal of the low-temperature liquid oxygen filling pump
Thread Content
If the temperature at which the pump is started is reduced – with pre-cooling requiring -130 degrees – and I further reduce it by 20 degrees, to -150 degrees for starting the pump, will this help to reduce wear on the shaft seal?
Of course, the more thorough the pre-cooling of the pump, the better~~ The main goal is to avoid damage to the pump caused by cavitation~~

The heat insulation performance of the inlet pipeline largely determines the cold pump time. Also, when using a cold pump, do not allow the pressure inside the pump to become too high
If the mechanical seal of this type of pump leaks, and the leakage is not severe, removing it, inspecting it, and adjusting the seal gasket usually allows it to continue to function for some time; this should extend its lifespan by 1/3
