This standard is not equivalent to ISO 2858-1975 (E) axial suction centrifugal pump (16ar grade) marking, rated performance points and dimensions in terms of pump marking and performance. This standard incorporates some performance specifications specified in ISO 2858-1975 (E) into this standard. According to the domestic market demand in my country, it also supplements three specifications that are not in the international standard, namely 150-100-200, 150-100-250 and 200-150-200.

Mechanical Industry Standard of the People's Republic of China JB/T8060-96 Bracket-type centrifugal pump Model marking, performance and dimensions 1996-(9-03) The Ministry of Machinery Industry of the People's Republic of China 1997-07-01 Implementation IR/E8060 In terms of marking and performance, the non-equivalent S0)285-!75(E) axial suction centrifugal pump (1ba grade> marking, rated performance points and dimensions. While incorporating some performance specifications specified in TS025%-197G(F) into this standard, according to the domestic market demand: This document supplements the 150-100-200 and 150-100250 set in the international standard and 200150200 and other - Format This standard was developed by the National Pump Standardization Technical Committee. This standard was drafted by Shenyang Water Evaluation Institute. The main person in charge of this standard is Zhang Wenda Mechanical Industry Standard of the People's Republic of China Bracket-type Centrifugal Pumps Model marking, performance and dimensions This standard specifies the model marking, performance and dimensions of bracket-type centrifugal pumps. This standard applies to bracket-type centrifugal pumps with a rated pressure not exceeding 1MP. 2 Cited standards JB/T 8060-96 The texts included in the following standard supplements constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown in the following standards are valid: All standards will be revised, and the parties using this standard should explore the possibility of using the latest versions of the following standards: G3316-89 GB/r13C0691 GB/T 13U7.91 High-centre pump, free-flow pump, axial pump and centrifugal pump test method High-centre, mixed-flow system and axial-flow pump NPSH centrifugal effect chamber 3. Model marking, performance and size 3.1 Carrier marking Bracket-type high-centre pump (abbreviated as teaching mark) is marked with three parts of the number, the first part indicates the impeller inlet diameter, the first part indicates the impeller outlet diameter. The second part indicates the nominal diameter of the impeller. Marking example, Suction diameter mm outlet diameter mm, nominal diameter of the system is: 80 50 250 The model writing is composed of two parts: code and mark. IT stands for bracket type centrifugal pump. Model designation method: impeller nominal diameter, outlet diameter, mru mru diameter, ranwww.bzxz.net I bracket type centrifugal system Example: The suction diameter is B(lumm, the discharge diameter is snmm. The impeller nominal diameter is 25cm. The model of bracket type centrifugal system: TT 8n-50-950 3.2 Performance and size 3.2.1 The performance and size of the pump are shown in Table 1 and Figure 1. The performance range of the pump is shown in Figure 2 and Figure 3. Approved by the Ministry of Machinery Industry in 1999-93 1997-017-Implementation JB/T 8D6U 3.2.2 The performance of the system in Table 1 is the performance under normal conditions. The performance characteristics are in accordance with the provisions of CB8216. 3.2.3 The outer dimensions of the system are shown in Table 2 and Figure 1. 3.2.4 The efficiency of the pump is in accordance with the provisions of GB/T1300 3.2.5 The cavitation margin of the system shall comply with the provisions of GB/T13GCG 1 The original rotation direction The rotation direction of the system is clockwise from the original direction, and the case is designed for internal rotation.
