3 Types
Test methods for centrifugal pumps, mixed flow pumps, axial flow pumps and vortex pumps Size of flange for gray cast iron pipes
Centrifugal pumps, mixed flow pumps and axial flow pumps NPSH Technical conditions for light and small single-stage centrifugal pumps
3.1 The structural type of the pump is axial suction, single-stage, horizontal, with the water outlet vertically upward and passing through the axis, the pump foot and the pump body are cast as one piece, and the bearing body does not have an intermediate bracket.
3.2 The connection dimensions of the pump inlet and outlet flanges shall comply with the provisions of GB4216. A square flange may be used for flanges with four connecting bolts. For pumps with an inlet nominal diameter less than or equal to 80 mm, the inlet may be threaded and the outlet may be connected with a 4-threaded square flange. 3.3 The power transmission mode between the pump and the diesel engine or motor is divided into direct drive (including coaxial) and belt drive. 3.4 Pump shaft rotation direction: For pumps with direct drive, the rotation direction is counterclockwise from the pump inlet; for pumps with belt drive, the rotation direction is clockwise from the pump inlet.
4 Model
4.1 Model indication method
The pump model is indicated by uppercase Latin letters and Arabic numerals, and the composition and meaning are as follows: IQ
Rated (standard) power of the power machine (keep one decimal place when matching diesel engine), kW (basic model can be omitted)
Transmission mode: D represents electric motor direct drive (basic model can be omitted), B represents belt drive (basic model can be omitted), C represents diesel engine direct drive Impeller nominal diameter, mm
Pump inlet nominal diameter, mm
