摘要(Abstract):

深冷泵多采用进口多弹簧串联机械密封,但价格高、供货周期长。对深冷泵用机械密封进行了国产化研究,所研制的机械密封实现了要求工况下平稳、长周期的运行。
From the investigation to Ethylene industries countrywide, it shows us that the most mechanical seals used for the deep cold pump are the multiple spring-tandem mechanical seals with a high price and a long delivery time.The mechanical seals (made in China) was re-designed on the request of Shenyang Petro-processing Pump Manufacture Co., Ltd.. It was tested and met the requirements of the smooth operation with long cycle in the conditions .
