石油五厂维修队广大职工,在工业学大庆群众运动中,大搞技术革新。1976年2月在北酮苯脱蜡车间混合溶剂离心泵(5FDJ-5×4)上进行了无水冷却试验,经过一年多的试验,效果很好,轴承温度不高,机械密封不漏,节约了用水,减少了污染。离心泵无水冷却,就是不用水作密封腔、轴承箱和机械密封格兰的冷却介质,改用输送介质——混合溶剂来冷却。泵体加装 The five oil factory maintenance team a large number of workers, industry in Daqing mass movement, vigorously promote technological innovation. February 1976 in the North ketone benzene dewaxing workshop mixed solvent centrifugal pump (5FDJ-5 × 4) on the anhydrous cooling test, after more than a year of testing, the effect is good, the bearing temperature is not high, the mechanical seal leak , Save water, reduce pollution. Centrifugal pump anhydrous cooling, is not water for the sealed chamber, bearing housing and mechanical seal Gelan cooling medium, switch to the transmission medium - mixed solvent to cool.
