我们发现一些化肥厂所使用的Z8-1.5/285-320循环压缩机,其填料函组件采用的是机油润滑和液氨冷却。图1为原润滑系统结构,该结构虽能对滑油和液氨有密封作用,但在装配时,特别是在维修装配过程中有很大困难。主要是由于填料函组件各零件制造误差,其累计值难以准确掌握。填料盒4上的进、出油孔与填料函箱体2上的螺纹孔很难保证同心度,使得油管接头1对不上填料盒4上的进、出油孔、滑油泄漏至填料盒外。活塞杆得不到润滑,其表
We found some Z8-1.5 / 285-320 cycle compressors used in fertilizer plants that use stuffing box components for oil lubrication and liquid ammonia cooling. Figure 1 shows the structure of the original lubrication system. Although this structure can seal oil and liquid ammonia, it is very difficult to assemble, especially during maintenance and assembly. Mainly due to the manufacture of stuffing box components error, the cumulative value is difficult to accurately grasp. The inlet and outlet holes on the stuffing box 4 and the threaded holes on the stuffing box 2 are difficult to ensure concentricity so that the inlet and outlet holes on the stuffing box 4 can not be matched with the oil pipe joint 1 and the oil leaks to the stuffing box outer. Piston rod is not lubricated, its table
