With the purpose of ensuring safe and good operation of the equipment, upgrading management level and creating economic benefits, the general equipment health assessment is developed by collecting information of 7 main indexes such as vibration, processing, electric, inspection, ambient temperature. The system also gives an idea of temperature normalization processing under changing conditions, and accurate judgement of abnormal equipment fault diagnosis by the expert system. Application shows that the health assessment system reflects general health condition of p u m p units objectively and effectively, improves accurac
