摘要： A variable level suction device used in conjunction with a transfer pump which transfers high-level radioactive liquid waste from a waste tank. The variable level suction device comprises an hydraulic housing and a telescoping pipe assembly comprising several pipe sections and mounted alongside the support column of the transfer pump. The telescoping innermost pipe section has a suction inlet, and the outermost telescoping pipe section is welded to the hydraulic housing which encloses an impeller assembly of either a submersible canned motor transfer pump or a lineshaft transfer pump. Suction ports in the hydraulic housing are located adjacent to the impeller assembly. Selective operation of the suction ports and the telescoping pipe sections allows the liquid waste to be suctioned either from the bottom of the waste tank or from a selected level in the waste tank between a free surface and a level near the suction inlet of the innermost pipe section of the telescoping pipe assembly.

摘要： A pump (14) having a shaft (34) and housing (32) containing pressurized system fluid variable between low pressure at pump startup and high pressure at pump operation, employs a hydrostatic sealing assembly (82) for sealably and rotatably mounting the shaft (34) within the housing. In the assembly (82), both a runner (44) mounted around the shaft (34) for rotation therewith and a seal ring (84) mounted to the housing (32) have facing surfaces (64, 92) between which pressurized system fluid creates a flowing low pressure fluid film which prevents contact between the facing surfaces (64, 92) so long as a predetermined minimum leakrate is maintained therebetween. Pressurized balance fluid is provided via a passage (102) through the housing (32) from the exterior thereof at a balance pressure greater than the supply pressure of the system fluid such that at both pump startup and operation, leakrates are produced between the runner (44) and seal ring (84) facing surfaces (64, 92) which are above the predetermined minimum.

摘要： A pump (14) having a shaft (34) and a housing (32) containing pressurized fluid variable in pressure between pump startup and operation employs a hydrostatic sealing assembly (82) for sealably and rotatably mounting the shaft (34) within the housing (32), which includes a runner (44) mounted around the shaft (34) for rotation therewith and a seal ring (84) mounted to the stationary housing. A flow control device (114) provided in the seal ring (84) is automatically operable in response to the supply pressure level to open communication of the pressurized fluid supply pressure with a seal ring second surface (88) at pump operation and to open communication of a fluid film low pressure between the runner 44 and seal ring 84 facing surfaces (64, 92) with the seal ring second surface (88) at pump startup.
