BA single-stage single-suction centrifugal pump structural characteristics

BA pump series of single-stage single-suction cantilever centrifugal pump for the suction to send water and physical and chemical properties similar to the water used in the liquid. Now through the graphic way to introduce the BA single-stage single-suction centrifugal pump structural features. BA single-stage single-suction centrifugal pump structural features BA-type pump main components are: pump (1); pump cover (2); impeller (3); shaft (4); and bracket (5). The outlet of the pump is perpendicular to the axis of the pump and can be rotated by 90 °, 180 ° and 270 ° together with the pump body according to the installation and usage conditions. The pump from the motor through the flexible coupling directly rotate, or through the belt drive rotation. The pump body (1) is made of cast iron. The pump body is internally formed with a flow channel which is gradually diffused to the outlet of the pump into a spiral shape. A pipe thread hole for installing a pressure gauge is drilled on the outlet flange. The pump cover (2) is made of cast iron, the flow channel is shrink-shaped, and a paper pad is padded between the pump body. The pipe flange on the inlet flange is drilled with a pipe screw hole for installing a vacuum gauge. The impeller (3) is made of cast iron, is a one-side water, has a curved blade inside, near the shaft hole, drilled a few holes to balance the axial force, but 11 / 2BA-6,2 BA-6 , 2BA-9,3BA-9,3BA-13,4BA-18,4BA-25, the impeller is not drilling, bearing axial force to withstand the manufacture, the static balance test. The shaft (4) is made of high-quality carbon steel with an impeller fixed on one end, and the shaft of the working shaft rotates in the ball bearing assembled in the bracket. Bracket (5) is made of cast iron, thin oil lubrication bracket oil chamber, the oil surface should always measure the oil level with oil ruler. Packing plays a sealing role, to prevent air seepage and a large number of liquid seepage, packing seal from the packing room, packing gland, packing ring, lead powder impregnated asbestos rope composition. A small amount of high-pressure liquid flows into the packing chamber through the water hole in the pump body, and functions as a water seal. Packing tightness must be appropriate, not too tight, nor too loose, the liquid can be a drop of oozing prevail, the filler is too tight, easy to heat, while consuming power, the filler is too loose, large liquid leakage, reducing pump efficiency If the filler is too much seepage, it should be added or replaced on time. Pump and motor mounted on a base, with flexible coupling connection, when installed, we must pay attention to motor and pump shaft in the same center line.
