First, on the matching motor power

    In order to reasonable matching motor, we learn from the advanced experience of the developed countries, the pump is divided into a, B, C three conditions adaptation level. If you use the C, B level conditions, according to the specific circumstances, the corresponding reduction in supporting motor power.

    A-class working conditions are: continuous operation, suction, flow, lift three performance standards (standard selected models);

    B class operating conditions are: continuous operation, the three performance only two standards;

    C class operating conditions are: continuous operation, the three performance is only a standard;

    Two, selection method of stainless steel self suction pump

    (1) performance parameters in the table "category code" column 1-5 meanings: type 1 is rectangular, type 2 cone type, type 3 for explosion-proof type, 4 for the outdoor type, type 5 for the mobile carts. "Material symbols" column in T, G, PP, BXG four groups of letters representing: iron, steel, reinforced polypropylene and stainless steel (1Cr18Ni9Ti) four kinds of material.

    (2) the model significance for example:

50 WFB-AD1

    50 caliber suction (mm) WFB self-priming pump without sealing performance of AD1 classification

    (3) complete model writing. Assume that the pump is modeling for the mobile carts, the material is reinforced polypropylene, suction diameter 50mm, classification performance as AD1. The full model of the pump is "5PP50WFB-AD1" ".

    (4) the flange of the water pump is manufactured by the national standard of the people's Republic of china. Standard code GB9115.2-88; GB9115.3-88. Non metallic water pump flange pressure 0.6MPa; metal water pump flange pressure 1.0MPa
