HW-Type Snail Shell Mixed Flow Pump Parameters
Product Profile
HW-type snail shell mixed flow pump is a high-energy-saving product designed according to the latest series of national standards. The pump is small in size, light in weight, large in flow, high in efficiency, good in cavitation, wide and flat in high-efficiency area, simple in structure, easy to use management methods and easy to repair. Suitable for farmland drainage and irrigation, industry, urban water supply and drainage and docks, docks, such as water.
Ⅰ: Overview
HW-type snail shell mixed flow pump is in accordance with the latest series of national standards designed for high-energy-saving products.
(1) The use of HW-type mixed-flow pumps is horizontal, single-stage, single-suction, cantilevered snail shell-type mixed-flow pumps, suitable for irrigation and irrigation of farmland, industry, urban water supply and drainage and docks, docks, etc.
(2) Features small size, light weight, large flow, high efficiency, good cavitation performance, wide and flat range of high-efficiency areas, simple structure, easy to use management methods, easy maintenance.
(3) Model description
Take 250HW-8 for example:
250: The inlet(outlet) diameter of pump is 250 mm in diameter.
8: The total head is 8 meters.
(4) The transmission mode of the water pump I plant production of HW series mixed-flow pump machine (electric) two-use, its rotation mode depends on the dynamic conditions of various regions, order according to the original motivation model (power, speed) to determine the transmission mode of the pump, to determine the size of the belt wheel or coupling specifications. (5) Pump steering: from the water pump in the in-water port to see the impeller is rotating counterclockwise (the direction shown by the arrow rotation).
