摘要： A seal chamber housing is provided for equipment with rotating shafts and includes a stepped conical bore open at the pumping mechanism end. The bore defines a seal chamber affording greater volume about the associated mechanical seals and a tapered bushing is optionally sealingly seated in the large diameter end of the stepped conical bore for excluding pump fluid from the seal chamber and/or preventing loss of seal flush liquid from within the seal chamber. In addition, the seal chamber includes upper and lower vent and drain ports primarily for use when the optional bushing is in place and said chamber also includes flushing fluid ports, a closed temperature-controlling external fluid channel and external air cooling features, all of which coact in various operating environments to provide longer and more efficient mechanical seal life.

摘要： A semi-cartridge seal is provided incorporating two components each comprising a plurality of preassembled parts. The first component includes an annular holder for snug but slidable positioning along a shaft and loosely supports an annular seal face structure therefrom with an O-ring seal forming a fluid tight seal between the seal face structure and the annular holder, centering the seal face structure relative to the annular holder and frictionally resisting rotation of the sell face structure relative to the annular holder, the latter being sealed relative to the associated shaft. The second component includes an annular gland insert loosely disposed about the shaft but including a centering bushing centering the gland insert relative to the shaft and the gland insert loosely supports a second seal face structure therefrom with a second O-ring seal forming a fluid tight seal between the second seal face structure and the annular gland insert and centering the second seal face structure relative to the annular gland insert, the second annular seal face structure being guidingly supported from the annular gland insert for shifting axially relative thereto and being yieldingly biased in one direction relative to the annular gland insert.
摘要翻译：提供了半盒式密封件，其包括两个部件，每个部件包括多个预组装部件。第一部件包括一个环形保持器，用于沿着一个轴向滑动定位，并且松散地支承一个环形的密封面结构，其中一个O形圈密封件形成在密封面结构和环形夹持器之间的流体密封密封，使密封面结构相对于环形保持器并且相对于环形保持器摩擦地抵抗销售面结构的旋转，后者相对于相关联的轴被密封。第二部件包括松散地设置在轴周围的环形压盖插入件，但是包括定心套管，其使压盖插入件相对于轴定心，并且压盖插入件从其中松散地支撑第二密封面结构，第二O形密封圈形成流体密封在所述第二密封面结构和所述环形压盖插入件之间并且使所述第二密封面结构相对于所述环形压盖插入件对中，所述第二环形密封面结构从所述环形压盖插入件导向地支撑，以相对于所述环形压盖插入件轴向移动并且在一个相对于环形压盖插入物的方向。
