摘要： A shaft seal of the mechanical face seal type split along a diametric plane thereof and which therefore can be installed relative to a shaft without disassembly of attendant equipment. The stationary and rotating components of the seal each may have the half elements thereof assembled in corresponding half elements of an attendant split annular holder and the holder half elements then may be engaged about the attendant shaft and be secured together. Thereafter, the assembled holders may be relatively axially shifted along the shaft toward engagement with each other and mounted in operative association with each other within a diametrically split gland housing, all of which relative assembly of the split stationary and rotating seal components in the corresponding split holder, assembly of the holders about the shaft and assembly of the assembled holders within the gland housing halves may be carried out by a single person, even within a crowded work area.
摘要翻译：机械面密封件的轴封沿其直径平面分开，因此可以相对于轴安装而不拆卸附属设备。密封件的固定和旋转部件各自可以将其半部件组装在伴随的分离环形保持器的对应的半部件中，然后保持器半部件可以围绕附带的轴接合并固定在一起。此后，组装的保持器可以沿着轴相对轴向移动，以彼此接合并且在径向分离的压盖壳体内彼此可操作地相关联地安装，所有这些夹紧壳体中的分离的静止和旋转的密封部件的相对组装在相应的分裂保持器，围绕轴的组件和组装的保持器在压盖壳体半部内的组装可以由单个人执行，甚至在拥挤的工作区域内。

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 seal assembly for sealing between a rotating shaft and a housing member is provided. The seal assembly includes a first annular seal member seated in the closed end of an annular axially opening recess rotatable with the rotating shaft and centered radially within the recess by resilient O-ring structure. A second stationary annular seal member is provided and is supported in a floating manner from the housing member or portion and axially shiftable relative to the housing member toward and away from the first annular seal member. The first and second annular seal members include opposing axial faces slidably and frictionally engaged with each other and spring structure is operatively connected between the housing member and the second annular seal member yieldingly biasing the second seal member toward the first seal member. The second floating seal member is radially centered by a resilient O-ring and the seal assembly is constructed whereby fluid pressure between the housing and the shaft will assist in yieldably biasing the second seal member toward the first seal member.
摘要翻译：提供了一种用于在旋转轴和壳体构件之间进行密封的密封组件。密封组件包括第一环形密封件，该第一环形密封件位于与旋转轴可旋转并且通过弹性O形环结构在凹槽内径向对中的环形轴向开口凹部的封闭端。第二静止环形密封构件被设置并以浮动的方式从壳体构件或部分支撑并相对于壳体构件朝向和远离第一环形密封构件轴向移动。第一和第二环形密封构件包括彼此可滑动和摩擦地接合的相对的轴向面，并且弹簧结构可操作地连接在壳体构件和第二环形密封构件之间，使第二密封构件向第一密封构件屈曲地偏置。第二浮动密封构件由弹性O形环径向居中，并且密封组件被构造成使得壳体和轴之间的流体压力将有助于可靠地将第二密封构件偏压朝向第一密封构件。

摘要： A cartridge type assembly is provided for use in conjunction with a housing wall having an opening thereof through which a rotary shaft projects. The assembly includes an inner bearing race supporting sleeve which is axially removably slidable, sealed relative to and releasably anchored in axial position on the shaft. A floating annular outer bearing race supporting housing is disposed about the sleeve and bearing structure including inner and outer races is stationarily supported from the sleeve and housing, respectively against axial and angular displacement relative thereto. The sleeve includes first rotary axial face seal ring structure removably stationarily supported therefrom in sealed engagement therewith and the housing includes second stationary axial face seal ring structure removably stationarily supported therefrom and with which the first rotary axial face seal ring structure is rotatably slidably engaged. A cylindrical fluid impervious bellows assembly is provided and includes opposite axial end portions removably secured to the housing wall about the opening therein in sealed engagement therewith and to the angular housing in sealed engagement therewith. The entire cartridge-type assembly may be readily quickly removed for servicing and/or replacement.
