Standby pump auto-start - 备用泵的自起动? In some application, it is necessary to have the standby pump to be on auto-start. A trip of the duty pump will start the stand-by pump with discharge valve full open. To meet this requirement, it is specified that the motor should be suitable for EOC (end of curve) operation and for full discharge open conditions. My question is that is this criteria adequate? Clients report that pumps still trip during such auto changeover. It is perhaps the high inertia during start up required which causes this. Any views on this subject? What additional specification should be added to meet the requirement? 中英文皆可。谢谢! regards Zhang ( oneplustech@yahoo.com )查看更多0个回答 . 2人已关注
