【正文】 om of seal chamber to isolate the heat from the impeller end. ? Used on high temperature applications to minimise heat load on the cooler by cooling only small amount of liquid that is recirculated. ? For high temperature boiler feed pump applications ? Other applications * high temperature liquid close to bubble point. API Piping Plans API 沖洗方案 Recirculation from pump discharge through a cyclone separator delivering clean fluid to the seal and fluid with solids back to pump suction line Clean overflow Underflow Inlet API Piping Plans API 沖洗方案 Points to Note for API Plan 32: Chose a proper source of seal flush to eliminate the potential for vaporisation of the injected fluid and to avoid contamination of the fluid being pumped with the injected flush. Install a labyrinth bushing at the bottom of the stuffing box to control the flushing and pressure if necessary. API Piping Plans API 沖洗方案 Single Seal Flushing from External Source 單密封通過外部來源進行沖洗 Throat Bushing Recirculation from pump discharge through a cyclone separator delivering clean fluid through a cooler and then to seal and fluid with solids back to pump suction line Cooling Water Outlet Cooling Water Inlet API Piping Plans API 沖洗方案 Needle valve External reservoir providing a deadended blanket of fluid to the quench connection of the gland. Points to Note for API Plan 51: Dead ended blanket on atmospheric side of seal to prevent freezing of moisture. Seal face will not stick together when the pump started.
