  • Publication number: 20240181471
    Abstract: A multi-cyclone sediment filter (100) includes a housing (260) disposed above and sealingly connected to a sediment bowl (110). A cyclone cartridge (370) is disposed in the cyclone housing (260), and has a plurality of conically shaped fluid cyclones (380), each having a small opening at a lower end and larger opening at an upper end, a fluid inlet into said cyclone housing (370) and for passage through said cyclone cartridge (370). A diffuser plate (510) sealingly connected to said cyclone cartridge (370) and housing (260), said diffuser plate (510) including diffuser tubes (520) extending downwardly into an upper open portion of one of said fluid cyclones (380), and a central upwardly extending diverter cone for directing fluid up and away from said diffuser plate (510).

  • Publication number: 20080008585
    Abstract: A centrifugal pumps secondary seal is disposed between the pump housing cover (130) in the seal chamber and includes a rotatable annular slinger (440) axially disposed on the pump motor shaft for slinging water away from the motor shaft and a flange protector (300) with a drain (400, 430) for diverting and directing free liquid from the seal chamber and outside the motor and pump housing (130, 230), thereby preventing corrosion of the seal chamber components, such as the motor flange (230), drive shaft and other motor components, due to exposure to water.

  • Patent number: 6856059
    Abstract: A turbine generator with stator windings and a hydrogen pressured stator frame, includes an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint; a terminal plate anchored to the collar across the circumference of the stator frame and marginally separated from the collar to form a first annulus that contains a first sealant composition that interfaces with the solder bond; and a hardening sealant applied to an upper portion of the solder joint. A high voltage turbine generator is sealed by filling a first annulus formed between an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint and a terminal plate anchored to the collar across the circumference of the stator frame with a first sealant composition; applying a hardening sealant onto the solder joint; and coextensively covering the first sealant composition and the applied hardening sealant with a second sealant composition.
