Inlet channel type
3.1.4| |tt||The pump inlet adopts a trumpet-shaped inlet channel. When the nominal diameter of the discharge port is greater than 1200mm, a square inlet channel can be used. 3.1.5 Minimum water inlet level
The pump inlet should be filtered at the lowest level. A certain depth below the water inlet level. The specific bay depth is given by the manufacturer. 3.2 Basic parameters | . The working range of the 3.2.2 series is shown in the figure. The specified point flow range is 0.57~11.38m/s, and the lift range is 10~24m. The inspection and deviation of the basic parameters listed in the table 3.2.3 are in accordance with the provisions of GB/T13008. . The Ministry of Mechanical and Electronic Industry approved the implementation on 1993-01-01 on 1992-07-20
