Thermal shock
Q - What sudden temperature rise can a pump withstand due to the mixing of two
different streams of hot liquid at its suction side?
A - We do not have enough information to establish an accurate limit of sudden
temperature change a pump can withstand without damage from thermal shock.
A centerline-supported radial-split case pump may be able to withstand a [ * ]
degree F sudden temperature rise. An axially-split foot-mounted pump may
withstand a lot less lower temperature rise, say [ * ] degrees F. Since this involves
mixing two liquids presumably at different energy gradient we assumed that the
liquid with lower energy gradient will act as heat sink and thus minimize the
abruptness of temperature change. These are ballpark figures only based on
non-recurring upset condition.
