由于泵送介质(油浆)温度高(360℃左右),密度大,且含有催化剂等固体颗粒,颗粒坚硬且易聚集,其中催化剂颗粒含量大于11g/l,密封端面磨损严重,甚至产生热裂现象;克隆公司生产的2.375/715型机械密封波纹管处杂质(催化剂颗粒,主要成分为Al2O3和SiO2)沉积严重,出现弹性失效现象。平均使用周期仅为20天左右,成为装置安全生产的隐患。本文着重从密封工况对机械密封的影
Due to the high temperature (about 360 ℃) of the pumping medium (slurry), the density is high, and solid particles such as catalyst are contained, the particles are hard and easy to aggregate. The content of the catalyst particles is more than 11g / l, Phenomenon; cloning company produced 2.375 / 715 mechanical seal bellows impurities (catalyst particles, the main components of Al2O3 and SiO2) deposition serious elastic failure phenomenon. The average life cycle of only about 20 days, a device safety hazards. This article focuses on the seal from the mechanical seal on the shadow
