auxiliary cooling circulating pump

                            auxiliary cooling circulating pump(acsm) is a new type of protective device for bcp. at present, to avoid aging and being scorched by high temperature of machine winding insulation of hot standby bcp, many bcps are forced to be put into operation, the original designed operation mode of two in operation and one for hot standby had been changed. that caused pointless wear of hot standby bcps as well as increase of energy consumption. the acsm can provide power for high pressure cooling circulation of hot standby bcp to effectively avoid extremly high water temperature inside bcp caused by heat conduction and accelerated aging of winding insulation. furthermore, it can prevent the winding insulation from being scorched when boiler water of high temperature seeps inside the motor. this device connects the original high pressure cooling pipeline system of bcp in the form of series connection, unchanging the original cooling system. since the improper operation mode is modified, each pump can save 1,500,000 kwh to 3,000,000 kwh for power plants every year. it is used in jiangxi fengcheng power plant, jiangsu jianbi power plant, shenzhen mawan power plant, shandong shiheng power plant, huaneng laiwu power plant, huaneng jiaxiang power plant, shanghai wujing power plant, hebei qinhuangdao power plant and other power plants with great effect.
