摘要： A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.

摘要： One aspect described in this application provides an apparatus that includes an external tray hose with an integrated booster pump for cooling a computing device. The booster pump can boost fluid flow and fluid pressure of coolant fluid pumped toward the computing device on a server tray. The booster pump includes a stator mounted around a booster pump housing with a bore. The stator includes one or more C-shaped lamination stacks for supporting coil windings. Energized coil windings generate a varying magnetic field for rotating an impeller within a housing bore to pump fluid along the housing bore of the booster pump. The apparatus includes a monitor module to monitor a set of sensors to obtain information about one or more of fluid temperature, fluid pressure, and device temperature; and a control module to adjust performance of the booster pump based on the information obtained from the set of sensors.

摘要： A circulation pump assembly (22) includes an electrical drive motor (10) and an electronic control device (12) controlling the drive motor (10). The control device (12) is configured for the speed control of the drive motor (10) according to a control schema (I, II, III). The control device (12) includes a detection function (42) which is configured to detect a condition variable representing an operating condition, from a parallel flow path (16, 18, 20) with a second circulation pump assembly (22). The control device (12) is also configured such that it can change the control schema (I, II, III) on the basis of a condition variable detected by the detection function (42). Further an arrangement of at least two such circulation pump assemblies (22) and a method for the control of such two circulation pump assemblies (22) are provided.

摘要： This disclosure includes subsea pumping apparatuses and related methods. Some apparatuses include one or more subsea pumps, each having an inlet and an outlet, and one or more motors, each configured to actuate at least one pump to communicate a hydraulic fluid from the inlet to the outlet, where the subsea pumping apparatus is configured to be in fluid communication with a hydraulically actuated device of a blowout preventer. Some subsea pumping apparatuses include one or more of: a desalination system configured to produce at least a portion of the hydraulic fluid; one or more valves, each configured to selectively route hydraulic fluid from an outlet of a pump to, for example, a subsea environment, a reservoir, and/or the inlet of the pump; and a reservoir configured to store at least a portion of the hydraulic fluid. Some apparatuses are configured to be directly coupled to the hydraulically actuated device.

摘要： An axial fan includes a housing, an upper motor, and a lower motor. The housing includes an upper housing and a lower housing. A lower peripheral wall of the lower housing includes first engaging portions and lower protruding pieces. The lower protruding pieces oppose the first engaging portions in an axial direction and protrude axially upward from an axially upper surface. An upper peripheral wall of the upper housing includes upper engaging claws and upper notch grooves. The upper engaging claws extend axially downward from an axially lower surface, and include a second engaging portion that engages with the first engaging portion in a lower end portion. The upper notch grooves are notched axially upward from the axially lower surface radially inward of the upper engaging claw. At least a portion of the lower protruding pieces is located in the upper notch grooves.

摘要： A turbine pump system includes a turbine pump assembly including a housing, a pump located in the housing, a turbine located in the housing and operably connected to the pump, and a heat exchanger located between the pump and a hydraulic fluid load. The heat exchanger is configured to reduce a temperature of a hydraulic fluid flow output by the pump and directed to the hydraulic fluid load. The heat exchanger is operably connected to a turbine gas flow and utilizes the turbine gas flow to cool the hydraulic fluid flow at the heat exchanger.

摘要： A home flood prevention appliance system includes controller circuitry disposed in a shroud above a cover of a sump basin, and a plurality of electrically operated sump pumps disposed in a lower portion of a structural frame positionable below the cover in the sump basin. The system also includes a water control actuator operable as a water main control device for a domestic water distribution network and a flow meter to measure the flow of municipal water supplied to the network. The controller circuitry configured to selectively energize the pumps to extract liquid from a sump basin based on a liquid level in the sump basin. The water control actuator controlled by the controller circuitry to shut off a municipal water supply to the domestic water distribution network in response to detection of a leak. Communication circuitry included in the home flood prevention appliance may wirelessly communicate.
