    Water pump

    Water pump

    In the hydraulic design, structural design and the wear-resistant materials used, this pump comprehensively applies the advantages of similar products at home and abroad and innovates. It has the characteristics of high efficiency and energy saving, low vibration, low noise, reliable operation, long service life and convenient maintenance.
    Structure:
    The pump is mainly composed of impeller, volute, back guard, shaft sleeve, bracket, support plate, shaft, bearing, bearing body and other parts. The impeller, volute, and back guard are made of high-chromium alloy cast iron. The impeller and the shaft are threaded. The volute, bracket, and bearing body are bolted. The pump shaft and motor can be driven by a coupling or a belt. The bearings are lubricated with grease and are shaftless pumps.
    The pump head part includes a pump casing, an impeller and a shaft sealing device. The pump head and the bracket are bolted together. The position of the water outlet of the pump can be rotated and installed at eight different angles at 45 intervals.
    The pump casing is a double-layer casing structure. The outer layer is a metal pump casing (front pump casing, rear pump casing), and its material is usually HT200 or QT500-7; the inner casing can be made of high-chromium alloy cast iron (including scroll casing, front shield, rear shield) , Or made of rubber (including front volute, rear volute).
    The impeller is made of high-chromium alloy cast iron and consists of a front cover, a rear cover, blades, and back blades. The leaves are twisted leaves, usually 3-6. The back blades are distributed on the outside of the front cover and the rear cover, usually eight. The impeller and the shaft are threaded.
    The shaft seal device has three types of auxiliary impeller + packing seal, packing seal and mechanical seal.
    The combined impeller + packing seal type consists of stuffing box, auxiliary impeller, water seal ring, packing, packing gland and shaft sleeve.
    Packing seal type is composed of stuffing box, spacer sleeve, water seal ring, packing, packing gland and shaft sleeve.
    The mechanical seal type is composed of a stuffing box, a spacer sleeve, a mechanical seal, a gland, and a shaft sleeve.
    The bracket part has two types of structure: horizontal center-opening and cylindrical.
