Mechanical Industry Standard of the People's Republic of China JB/T6534-92 Centrifugal Sewage Pump Published on December 25, 1992 Type and Basic Parameters Implemented on July 1, 1993 Published by the Ministry of Machinery and Electronics Industry of the People's Republic of China Mechanical Industry Standard of the People's Republic of China Centrifugal Sewage Pump Type and Basic Parameters 1 Subject Content and Scope of Application JB/T6534-92 Replaces JB2975-81 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 GB7021 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.
