摘要： A wiper seal assembly for a reciprocating pump, the pump including a power section configured to be powered by a motor, a fluid section having an inlet and an outlet, and a plunger having a longitudinal plunger axis, a first end coupled to the power section, and a second end opposite the first end and disposed within the fluid section. The wiper seal assembly includes a cover mounted to the power section. In addition, the wiper seal assembly includes a first wiper seal radially disposed between the cover and the plunger. Further, the wiper seal assembly includes a splash guard disposed about the plunger and axially spaced from the cover. Still further, the wiper seal assembly includes a biasing member axially biasing the splash guard away from the first wiper seal.

摘要： A live-loading assembly for exerting a sealing force on a compressible packing structure of a fluid handling device, such as a valve or pump, includes a pair of gland bolts each movably extending through opposite end lids of a tubular cartridge and through a Belleville spring stack disposed within the cartridge and bearing on a tubular piston rod having an end portion extending outwardly through one of the lids and having a spring force indicating scale disposed thereon. When packing force adjustment nuts are tightened onto the bolts, to increase the compression force exerted on the packing structures, one of the lids on each cartridge moves along the associated exposed piston rod scale to thereby provide a visual indication of the amount of spring force being created by each tightened nut.

摘要： In accordance with the present invention, there is provided a fluid or liquid barrier packing system which is adapted to minimize VOC emissions, while also providing live-loading and continuous load monitoring functions. The components of the packing system (including the liquid barrier) are adapted to be installed in a traditional stuffing box of a valve utilizing a top entry method, and without the necessity of having to inject the liquid through any side ports of the valve. The packing system reduces leakage levels as required by low emission leakage specifications by creating a reverse osmosis effect, limiting the diffusivity of a gas through the packing elements of the system. Thus, the packing system of the present invention provides a simplified method to load and monitor a barrier in the stuffing box of the valve to slightly higher pressure than processed fluid pressure.
摘要翻译：根据本发明，提供一种适于最小化VOC排放的流体或液体屏障填料系统，同时还提供活载和连续载荷监测功能。包装系统（包括液体屏障）的部件适于安装在利用顶部进入方法的阀的传统填料箱中，并且不需要通过阀的任何侧面端口喷射液体。包装系统通过产生反渗透效应来降低低排放泄漏规格所要求的泄漏水平，从而限制气体通过系统的包装元件的扩散性。因此，本发明的包装系统提供了一种简化的方法，用于将阀的填料箱中的阻挡件加载和监视到比被处理的流体压力略高的压力。

摘要： A sealing system for a pump includes a housing having an internal chamber adapted to receive a portion of a plunger. A primary seal is translatable within the chamber in sealing relation with the housing. The primary seal includes first and second elastomeric members adapted to sealingly engage the plunger. The first and second elastomeric members are spaced apart from one another a distance greater than or equal to a maximum stroke of the plunger. A secondary seal is spaced apart from the primary seal and adapted to sealingly engage the plunger. A chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressurizing device maintains a pressure of barrier fluid at a magnitude greater than a peak pressure of a fluid pumped by the plunger such that the pumped fluid is restricted from entering the barrier fluid chamber.

摘要： A seal assembly for use between wellbore tubulars employs an inner seal ring partially circumscribed by an outer seal ring. The seal rings are axially slidable with respect to one another and can be made from pliable inelastic materials such as graphite or a fluoropolymer. The seal rings contact one another along profiled surfaces that are angled such that by axially urging the seal rings towards one another produces a bulge in the seal assembly directed radially outwards and inwards. The bulging seal rings come into contact with opposing sides of the wellbore tubulars to define a sealing surface. Axial supports at opposing lateral ends of the seal rings maintain the seal between the tubulars.

摘要： The invention pertains to a sealing arrangement 10, 10a, which acts between a housing 12 and a component 14 installed in the housing 12, with a stop 16, permanently connected to the housing 12; with a spring 20, which is supported on the stop 16; and, with at least one first sealing element 22 in working connection with the spring 20. Abutment 34 is designed to be adjusted against the force of the spring such that the spring 20 is completely compressed—squeezed into a block—and additional load can be exerted on the sealing element 22, so that in particular any leakage which has developed can be stopped—on an emergency basis—by the exertion of additional load on the sealing element 22, which has the effect of increasing the sealing force which the sealing element 22 exerts.
