摘要(Abstract):

介绍了研制成功的“八”字形螺旋槽端面密封。它是一种新型流体动压非接触式机械密封,克服了在“人”字形螺旋槽端面密封中可能产生的磨粒磨损和冲刷磨损,实现了超高速、零泄漏和微磨损。该密封采用自循环螺旋泵与油气压差控制器相结合的密封油循环控制系统,具有简单可靠、节能等突出优点。
A type of spiral groove face seal with special patten of "八" is invented and developed. It is a new type of hydrodynamic non-contacting face seal with unique performance of super-high speed, no-leakage and micro-wear. The oil circulating system of the seal consists of self-effecting screw pump and a controler of differencial pressure of oil and gas, which is simple reliable, energe-saved and economical. This seal and its Supporting system is mainly used for gas compressors with high speed in the petrochemical industry.
