JB/T 8095-1999 This standard is a revision of JB/T 8095-95 "Types and Basic Parameters of Centrifugal Oil Pumps". This standard specifies the types and basic parameters of centrifugal oil pumps. This standard applies to centrifugal oil pumps used in refineries, chemical and petrochemical processes to transport petroleum and its products without solid particles (abrasives). This standard was first issued on March 31, 1989 as GB 10883-89 and was adjusted to JB/T 8095-95 in April 1996.

This standard is a replacement for JBTB09S.195 "Types and basic parameters of centrifugal oil pumps". During the revision, the original standard was revised and the main technical content was changed. This standard replaces JB/TS095.1.95 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Pump Standardization. And the standard drafting unit: Zhenyang Water Resources Research Institute. The main drafters of this standard are Zhou Shaozhu and Huang Gongying. This standard was first issued in 1989 as GD10893-9 and adjusted to JB/T8095.1-95 in 1996. 1 Scope

This standard applies to centrifugal oil pumps used in refineries, chemical plants and petrochemical processes to transport petroleum and its products without solid particles (abrasives). According to the temperature and properties of the transported liquid, the materials of the remaining main parts are divided into the following three categories: Class 1 ferrophosphorus materials, temperature -20~+200℃: Class 2 carbon steel materials, temperature -45-+400: Alloy steel materials: temperature -45~+40,
Class 1
Performance of centrifugal oil systems (design point): 6.25-.500mh: 60.603m. 2 Cited standards

Centrifugal pumps, mixing pumps, axial flow pumps and vortex pumps are used for testing centrifugal systems, perfusion pumps and axial flow steam centrifugal systems are used for testing centrifugal systems. The centrifugal oil is horizontal, the shell is radially divided, the bearing form is centrally supported, and the suction and discharge directions are vertically upward. According to this standard, it can be divided into one of the following types: a) single-stage single suction, single-stage double suction and two-stage single suction arm type; h) single-stage double suction, two-stage single suction and two-stage double suction end support type; e) multi-stage single suction and case-stage double suction segmental type, model
