1. On the auxiliary motor power
In order to match the motor reasonably, we draw on the advanced experience of the developed countries and divide the water pump into three conditions of A, B and C. If you use in the B and C conditions, the corresponding motor power can be reduced according to the specific conditions.
Class a condition condition is: continuous operation, suction range, flow, lift three performance are required to reach the standard (the selected model standard);
B operation condition is: continuous operation, three performance only needs two items.
C operation condition is: continuous operation, three performance only need one standard;
Two, type selection method of stainless steel self priming pump
(1) &ldquo in the performance parameter list; category code ” the 1-5 meaning of the column: 1 is rectangular, 2 is cone, 3 is explosion-proof, 4 is outdoor, 5 is cart mobile. “ material symbol ” in the column T, G, PP, BXG four groups of letters respectively: iron, steel, reinforced polypropylene, stainless steel (1Cr18Ni9Ti) four kinds of material.
(2) examples of model significance:
50 WFB-AD1
AD1 performance classification of 50 mm WFB non sealed self-priming pump
(3) complete model of model writing. It is assumed that the requirements of the pump are: the model is the moving type of the cart, the material is reinforced polypropylene, the suction caliber is 50mm, and the performance is classified as AD1. The complete model of this pump is “ 5PP50WFB-AD1”
(4) the flange of the pump is made by the national standard of People's Republic of China. Standard code GB9115.2-88; GB9115.3-88. Flange pressure of non-metallic water pump 0.6MPa; flange pressure of metal material pump 1.0MPa
