Instructions for the preparation of the pump engineering design regulations HG/T20704.7-2000bzxZ.net
Subject content and scope of application
This standard specifies the purpose and requirements for the preparation of the pump engineering design regulations. Applicable to technical management and design quality management.
Purpose of preparation
The pump engineering design regulations are a relatively complete general regulation for pump design. The purpose of its preparation is: on the one hand, to explain and determine the design criteria and design requirements of the pump, drive device and its supporting auxiliary equipment to be provided to the user (owner) of this project; on the other hand, to require designers to carry out their work in accordance with the specified unified requirements; at the same time, it is also to obtain the review and confirmation of the user (owner) in advance, and serve as the technical basis for the preparation of equipment (inquiry, ordering) technical documents. The engineering design regulations must be reviewed and agreed by the user (owner). They must be followed and implemented in engineering design. 3 Main Contents
The main contents of the engineering design regulations generally include the following aspects, which can also be increased or decreased as needed: 3.0.1

Drawings and materials.
Preparation requirements and instructions
4.0.1 This regulation is specially prepared for a specific engineering project. It is applicable to a certain type of machine pump in this project: such as centrifugal pump, reciprocating pump, rotary pump, centrifugal compressor, reciprocating piston compressor, blower, steam turbine, etc. It stipulates the general design criteria and requirements of this type of machine pump, and the special requirements for a certain machine pump will be explained in the data sheet. When compiling the regulations, it is usually possible to refer to the relevant professional standards and specifications currently in use internationally, or the standards and specifications issued by the state and the ministry, as well as to compile them according to this project or a special requirement. It is also possible to refer to the general design regulations of a certain type of pump and compile them according to this project or a special requirement. 4.0.2 Certain mandatory rules or regulations (such as relevant national laws and regulations) should also be included in the engineering design regulations.
If the user (owner)'s supplementary and modified opinions are correct, they should also be included in the engineering design regulations and issued as a revised version. 4.0.3
