Analysis and Control of Abnormal Oil Quality of Steam Feed Pump of 330MW Unit
The 330 MW unit of a power plant was put into formal operation in October 2014.During the oper-ation of the unit,the cyclic test of the steam feed pump was carried out,and it was found that the moisture and particle size of the lubricating oil of the B steam feed pump exceeded the standard frequently.The turbine is spe-cialized in using an external oil filter to filter the water in the oil and improve the particle size of the oil,but the maintenance time is short after the oil index is qualified.The water content in the lubricating oil of the small ma-chine exceeds the standard,which will affect the normal operation of the equipment and even cause the feed pump to trip.Based on the test data,this paper analyzes the main causes of abnormal oil quality,and puts forward fea-sible control measures to ensure the safe and economic operation of the unit.
