摘要(Abstract):

针对高扬程大型离心水泵采用“闭阀起泵,关阀停泵”工作方式,开停泵过程中对机组及配套设备产生很大的冲击,提出了在水泵配套同步电动机中采用软起动软停机技术,可以有效减轻振动,延长设备使用寿命。
In view of very sharp impact to the unit and the supplementary equipment during the starts and stops pump in the process,which is resulted from the application of the "After valve closure engine off,Under the valve off-position starts the water pump" the work way,used in the high-lift large-scale centrifugal pump.Application of the soft start and soft stop technology in the water pump necessary synchronous motor was proposed,which can reduce the vibration phenomenon and lengthens the life of equipment effectively.
