Mechanical seal flushing water and bearing cooling water supply device of centrifugal pump

The utility model discloses a mechanical seal flushing water and bearing cooling water supply device of a centrifugal pump, which is mainly used for supplying mechanical seal flushing water of the centrifugal pump and bearing lubricating oil cooling water at two ends of the pump in long-distance large-pipe-diameter high-lift pipeline transportation and transfer water applied to complex terrains. A four-way connector is installed on a water diversion pipeline, one end of the water diversion pipeline is installed on a centrifugal pump, a water outlet of the four-way connector is connected to mechanical seal water supply openings in the two ends through pipes, mechanical seals are flushed, and the mechanical seal water supply pipelines are in T connection with a connecting pipeline and cooling water tanks connected to bearings at the two ends of the pump respectively. A circulating washing and cooling system is formed through the pressure difference between the pump and the bearing lubricating oil cooling water
