This standard specifies the type and basic parameters of centrifugal sewage pumps (hereinafter referred to as "pumps"). This standard applies to pumps that transport sewage, feces or liquids containing solid suspended matter such as fiber, paper scraps, fruit, fish, etc. 2 Reference standards

Centrifugal ticket terminology
JB/T6535 Technical conditions for centrifugal sewage pumps 3 Terms
3.1 The terminology used in this standard shall be in accordance with the provisions of GB7021. 3.2 The special terms in this standard shall be in accordance with the provisions of JB/T6535. 4 Types and basic parameters
4.1 Structural type
Pumps are divided into two types: single-stage, horizontal or vertical. Pumps with a discharge port diameter less than or equal to 250mm are single-suction and axial suction; pumps with a discharge port diameter greater than 250mm should generally be double-suction. 4.1.1 Horizontal pumps should be discharged vertically upward, or change the discharge direction at 45° or 90°. 4.1.2 Horizontal pumps with a discharge port diameter less than or equal to 150mm should have two types: ordinary type and corrosion-attached type. 4.2 Basic parameters
4.2.1 The basic parameters of the pump are as specified in the table. The values ​​in the table are the performance values ​​at the specified points for clean water at room temperature. The efficiency values ​​in the table are the efficiencies of ordinary closed impellers. When the impeller is open, its efficiency percentage can be reduced by 5 according to the value specified in the table; when the impeller is a single-channel, its efficiency percentage can be reduced by 10 according to the value specified in the table.
