Vertical circulating water pumps SHB-III water circulation pump works: the pump is installed in the amount of water as the working fluid. When the impeller is rotated in the clockwise direction in Fig, water is thrown around by the impeller, the action of centrifugal force, the water forms a closed ring shape of the cavity of the pump depends on the thickness and other similar. The inner surface of the lower portion of the water ring coincided with the impeller hub tangent, surface coincides with the blade tip (actually leaves in the water ring has given insertion depth) within the upper part of the water ring. Forming a crescent space between the impeller hub and the water ring at this time, and this space has been divided and the number of impeller blades equal number of small cavities. If zero is the starting point for the lower impeller, the impeller rotates 180 degrees before the small cavity size from small to big, and with the end face of the intake port connected, then the gas is inhaled, when the suction end of the cavity is small and the suction port isolation; When the impeller continues to rotate, the small chamber from large to small, the gas is compressed; small chamber when communicating with the exhaust port, the gas will be discharged pump.
