过去,不少油库是利用清水泵输送常温轻质油料。其泵轴密封大多采用填料式密封装置。由于装填的油浸石棉盘根缺乏弹性,密封效果差。压得过紧,易引起过热,增加泵轴磨损,降低泵的效率;压得过松,易发生渗漏。安装这种泵的油库泵房里,往往是污油遍地,油味刺鼻,油蒸气浓度颇大,很不安全。为解决这个问题,我们用汽车油封中的耐油橡胶油封圈代替石棉绳填料。经过几个油库几年的实际使用,证明了使用油封密封装置,性能良好,装填简便,价格便宜,使用寿命也长(可用一、二年不更换)。
In the past, many oil depots used clear water pumps to deliver light oil at ambient temperature. Most of its pump shaft seal packing packing. Due to the lack of elasticity of the filled asbestos packing, the sealing effect is poor. Press too tight, easy to cause overheating, increase shaft wear, reduce pump efficiency; pressure too loose, prone to leakage. Install this pump oil depot pump room, often dirty oil everywhere, pungent oil, oil vapor concentration is quite large, very unsafe. To solve this problem, we replace the asbestos rope filler with the oil-resistant rubber oil seal in the automobile oil seal. After several years of actual use of oil depot, proved the use of oil seal sealing device, good performance, simple filling, low cost, long service life (available one or two years without replacement).
