国外离心泵技术标准先进性研究

Advancement Research of Foreign Centrifugal Pump Technical Standards

为了减少离心泵故障率,降低维护成本,全面梳理了国内外离心泵运行管理标准。从离心泵设计安装、运行管理和维护修理等三个方面,深入研究了国内外离心泵技术标准国的差异。系统阐述了俄罗斯标准、美国标准和ISO标准的先进性,包括泵与出入口管道的连接要求、泵房通风系统控制逻辑关系、泵基础下陷情况监测、泵紧急停车的情形、泵检测维修周期以及泵轴承箱和泵轴的振动幅度和速度限制等。最后,针对借鉴国外标准先进理念,提高我国离心泵运行管理标准水平,以及加强标准制修订工作,提出了建议。

In order to decrease failure rate and maintenance cost of centrifugal pumps, domesticand international operation and maintenance standards for centrifugal pumps were roundly classified.In allusion to design and installation and operation and management and maintenance and repair ofcentrifugal pumps, difference between domestic and international technology standards of centrifugalpumps were studied in detail. The advancement of Russia standards and American standards and ISOstandards were systematacially expounded, including connection requirements of pumps and inlet/outlet pipeline, and logical control relationship for pumps house vent systems, and pumps base sinkinginspection, and pumps emergency shutdown conditions, and pumps inspection and maintenance periods,and vibration and speed for bearing box and pumps shaft. Finally, by means of learning foreign standards,recommendations are made to raise the level of centrifugal pumps operation and management standardsand strength the work of standards revision and development.
