The pump is a single-stage double-suction horizontal type. The casing is a horizontal split type. 3.2 Basic parameters
3.2.1 The basic parameters of the pump shall comply with the provisions of Table 1. The parameters of the pump under reduced speed conditions are shown in Table 2. The values ​​listed in the table are the performance at the specified point. The performance operating range of the pump is shown in Figures 1 and 2. 3.2.2 The efficiency of the pump shall comply with the provisions of GB/T13007. 3.2.3 The NPSH of the pump shall comply with the provisions of GB/T13006. 3.2.4 The performance inspection and deviation of the pump shall comply with the provisions of GB5658. 3.3 Model designation method
3.3.1S-type pump
Code for small impeller diameter (indicated by A, B..., normal impeller diameter is not indicated) Head, m
Single-stage double-suction clean water centrifugal pump (from the drive end, the pump rotates clockwise) Inlet diameter, mm
Example: The model of a single-stage double-suction clean water centrifugal pump with an inlet diameter of 300mm, a head of 32m and a normal impeller diameter is 300S32. 3.3.2Sh-type pump
