Types and basic parameters
1 Subject content and scope of application
This standard specifies large and medium-sized vertical axial flow pumps ( Hereinafter referred to as the type and basic parameters of the system). JB/T 688393
This standard is applicable to pumps that transport clean water or other liquids with physical properties similar to clean water or seawater and liquids containing a small amount of solid particles. 2 Reference standards
GB/T13008 Mixed flow system, axial flow pump technical conditions 3 Type and basic parameters
3.1 Type
3.1.1 The pump structure is vertical, and the blade adjustment type is half Adjustment or full adjustment, 3.1.2 The pump water inlet is generally a trumpet-shaped water inlet. When the nominal diameter of the discharge port is greater than 1000mm, a shape-shaped suction elbow or other types of water inlet can be designed.
3.1.3 The pump discharge port is generally a 60° water outlet elbow. 3.1.4 The pump water inlet should be submerged to a certain depth below the minimum water inlet level. The specific submersion depth is given by the manufacturer. 3.2 Basic parameters
3.2.1 The basic parameters of the ticket should comply with the provisions of Table 1. The basic parameters in Table 1 are the values ??at the specified point when using clean water at normal temperature. 3.2.2 The working range of the pump is shown in the figure. The prescribed point flow range is 1.33~14.5m/s, and the lift range is 3~13.7m. 3.2.3 The inspection of the basic performance parameters listed in the table shall be in accordance with the provisions of GB/T13008. 3.3 Model representation method
