自七十年代以来,我国先后从国外引进了一些比较先进的石油钻采设备,从中发现国外对这些设备的润滑密封问题十分重视,所用润滑密封材料质量优良,远非一般密封润滑油脂能比拟。相形之下,以往我们对达方面的问题认识不足,所用密封润滑材料多为几十年前的老产品,质量差,致使设备润滑不良,磨损加怏,达不到预期使用效果。为了改变这种状 Since the 1970s, China has introduced some advanced oil drilling equipment from abroad. It has found that foreign countries attach great importance to the lubricating and sealing problems of these equipment. The lubricated sealing materials used are of good quality, which are far beyond the ordinary sealing lubricants. In contrast, in the past, we did not know enough about Da’s problems. The sealing lubricants used were mostly old products of a few decades ago. Their quality was poor, resulting in poor lubrication of the equipment and increased wear and tear, which did not reach the expected results. In order to change this shape
