摘要
介绍了一种改进后的新型容积泵泵体阀组密封压紧结构。该装置采用双层分压式密封形式,由压板对垫片进行压紧,由压圈对填料进行压紧,通过分别单独压紧泵体"内"密封和"外"密封,有效地避免了在高交变载荷下密封泄漏的问题。
This paper introduces a kind of improved sealing structure of volumetric pump body valve group. The equipment adopts double layer partial pressure seal form, pressure plate compacts the gasket, and pressure ring compacts the packing.By separately compacting the inner seal and the outer seal of the pump body separately, the problem of sealing leakage under high alternating load is effectively avoided.
