摘要： A purge apparatus is provided. The purge apparatus is capable of preventing air from being entrained when a submersible pump is moved into a pump column, and capable of warming the submersible pump when the submersible pump is removed from the pump column to thereby prevent component of the air from being liquefied, thus preventing the liquefied gas from being emitted in the atmosphere. The purge apparatus includes a hermetic purge container configured to accommodate the submersible pump therein; a vacuum line coupled to the hermetic purge container and coupled to a vacuum source; a purge-gas supply line coupled to the hermetic purge container and coupled to a purge-gas supply source; and a purge-gas supply valve mounted to the purge-gas supply line.

摘要： A submersible electric machine for transporting a liquid, the machine having a hydraulic unit with an impeller, and a drive unit with a housing defining a motor compartment having an electric motor inside. A drive shaft is connected to the electric motor, and extends from the electric motor to the hydraulic unit to a connection with the impeller. A top unit includes a housing defining an electronics chamber separated from the motor compartment by a dividing structural wall. The electronics chamber has a metal partition, having a natural frequency equal to or more than 500 Hz, connected to the top unit housing. A vibration sensor is directly or indirectly connected to the metal partition and monitors vibrations in at least two dimensions at frequencies ranging up to 500 Hz.

摘要： A sump pump system enables automatic determination and utilization of frequencies for mechanical shakers for sump pumps. These techniques may be implemented to detect a fault (e.g., a stuck impeller) with a sump pump and to identify a desirable frequency at which a mechanical shaker for the sump pump should vibrate to correct the fault.

摘要： An integrated pressurized pump shaft seal assembly for a submersible rotary fluid pump comprises an oil reservoir having a pressure equal to or less than the ambient pressure external fluids surrounding the casing, the oil reservoir feeding an oil pump impeller that is mountable onto, so as to be rotated by, the rotary fluid pump shaft. The oil pump impeller is in fluid communication with an internal volute diffusion element integrated into a pump component. The centrifugal oil pump impeller pumps oil from the oil reservoir to the seal chamber through the internal volute diffusion element so as to increase a pressure within the seal chamber to a positive pressure above the ambient pressure of the external fluids surrounding the pump housing.

摘要： An assembly, comprising a basin, a submersible pump, having an outlet, disposed within the basin, and an adapter. The adapter comprises a housing having a first side and a second side, a reducing passage extending axially through the housing from the first side to the second side, wherein the reducing passage has a varying inner diameter such that a first inner diameter transitions to a second inner diameter, a plurality of fastener receiving holes extending transversely through the housing and disposed radially and circumferentially around the reducing passage, and a plurality of fastening elements extending from the housing at the second side. The submersible pump outlet is connected to the adapter on the second side and an existing discharge line connected to the adapter on the first side. The adapter provides a transition from a diameter of the submersible pump outlet to a diameter of the existing discharge line.

摘要： Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.
