Grand Shaft Seal Water Leakage

The main forms of leakage of mechanical seal of water pump are: leakage caused by pressure, leakage caused by medium, periodic leakage of mechanical seal, dry friction or roughening of seal face caused by insufficient lubricating oil on seal face. According to the standard HG2099, the leakage is the volume of equivalent liquid under this pressure, which is specified as: when the shaft diameter is greater than 80mm, the leakage is not greater than 10ml /H; when the shaft diameter is not greater than 80mm, the leakage is not greater than 8ml / h.

GE-343 seal water flow switch adopts the display window isolated from liquid to observe the flow of shaft seal water in real time. When the flow of seal water is significantly greater than the normal flow, it can be judged that there is a possible seal water leakage, and it should be checked in time to see if there is a seal water leakage.
