气体压缩机是石化装置的关键设备,多年来在重整装置循环气压缩机一直采用机械式浮环密封,该机组常常因浮环密封失效而停车抢修,失效情况时有发生。经过反复论证并试验,将浮环密封改为干气密封,改造后一次开车成功,密封效果显著,运行情况得到改善。
Gas compressor is the key equipment of petrochemical plant. Over the years, the recycle gas compressor of reformer has been adopting the mechanical floating ring seal. The unit often stops and repairs because of the failure of the floating ring seal, and the failure occasionally occurs. After repeated demonstration and test, the floating ring seal was changed to dry gas seal, a successful drive after transformation, the sealing effect is significant, the operation has been improved.
