With Inlet And Outlet Connections Patents (Class 415/112)
  • Patent number: 10718336
    Abstract: A molten metal pump assembly and method to fill complex molds with molten metal, such as aluminum. The pump assembly includes an elongated shaft connecting a motor to an impeller. The impeller is housed within a chamber of a base member such that rotation of the impeller draws molten metal into the chamber at an inlet and forces molten aluminum through an outlet. A first bearing is adapted to support the rotation of the impeller at a first radial edge and a second bearing adapted to support the rotation of the impeller at a second radial edge. A bypass gap is interposed between the second bearing and the second radial edge. Molten metal leaks through the bypass gap at a predetermined rate to manipulate a flow rate and a head pressure of the molten metal such that precise control of the flow rate is achieved.

  • Patent number: 10480520
    Abstract: HVLP (High Velocity Low Pressure) motor-driven fans and other types of fans, blowers and vacuums include one or more features for minimizing vibration and eliminating other causes of fan or motor failure. Examples of such features include a fan blade with a particularly short tail section, a fan wheel spacer with a counterbore in an axial face of the spacer, and a small boss or thin shim adjacent to a screw that clamps an assembly of stator laminations between two motor brackets. The tail section, being relatively short, resists bending during high speed rotation, thereby preventing vibration. The counterbore in the spacer provides the spacer with resilience for maintaining an axial clamping force even as part dimensions change due to thermal expansion. The boss or shim allows the screw to tightly clamp the stator laminations without cracking either of the motor brackets.

  • Patent number: 9447695
    Abstract: A diffuser seal for an aft end of a high pressure compressor of a gas turbine engine is disclosed. The diffuser seal includes a flow guide carrier coupled to the diffuser case. The flow guide carrier is also coupled to a static seal. The static seal engages a rotary seal and permits air flow through the static and rotary seals in the aft direction. The flow guide carrier is also coupled to a fairing and a fairing/hub support. The flow guide carrier supports the fairing in a spaced-apart position with respect to the rear hub so that air flowing through the static and rotary seals passes between a forward surface of the fairing and the rear hub. The fairing/hub support extends forward from the flow guide support and engages an aft surface of the fairing thereby limiting movement of the rear hub and fairing in the aft direction. This design helps to prevent parts or debris from piercing the rear hub and entering the high pressure turbine in the even of a fan blade-out or fan blade-off event.

  • Patent number: 8979478
    Abstract: A bearing and seal assembly for supporting and sealing a terminating outboard end of an impeller shaft in a centrifugal pump such as a between-bearings pump includes only one seal but provides advantages typical of a dual-seal assembly, including barrier fluid protection against seal damage caused by abrasive slurries, and protection against leaking of toxic process fluid to atmosphere. A bearing housing sealed to the pump's pressure casing encloses the seal, bearing, and terminating impeller shaft end. Leakage of process fluid past the seal is prevented by a lubricating, pressurized, cooled barrier fluid which is circulated through the bearing housing by an external pump and/or by an internal, shaft-driven impeller. Because the impeller shaft terminates within the bearing housing and does not penetrate to atmosphere, the barrier fluid is contained within the bearing housing and a second seal is not required.

  • Patent number: 8961102
    Abstract: A system and method for sealing a shaft disposed for rotation within a casing, where two axially-spaced seal rings of an oil film seal extend around the shaft and define a clearance therebetween. Oil is pumped into the clearance from an oil reservoir and a portion of the oil is received in an annular port defined in the casing between an outer labyrinth seal and one of the axially-spaced seal rings. The oil mixes with a process gas to for an oil and gas mixture. A blower is in fluid communication with the annular port and circulates the oil and gas mixture to a trap where the oil is separated from the process gas and a separated process gas is returned back to the annular port.

  • Patent number: 8961100
    Abstract: An exemplary valve device for controlling flow of a turbomachine fluid includes a housing and a flow control assembly within the housing. The housing has a first inlet, a second inlet, and an outlet. Movement of the housing to a first orientation causes the flow control assembly to move to a first position to restrict flow of a turbomachine fluid into the housing through the second inlet. Movement of the housing to a second orientation causes the flow control assembly to move to a second position to restrict flow of the turbomachine fluid into the housing through the first inlet.

  • Publication number: 20140321972
    Abstract: Systems and methods for assuring a safe working condition of a dry gas seal when a pump/compressor is in a standstill condition. A small booster compressor is added to boost the pressure of an intermediate buffer gas injected into the chamber between a primary seal and a secondary seal of the dry gas seal. Control components detect when the barrier gas pressure drops below a preconfigured value and when detected, closes a valve in a line to a flare safe area and turns on the compressor. The boosted intermediate buffer gas, Nitrogen or dry air, slows the flow of untreated process gas through the primary seal of the dry gas seal and prevents icing of the primary seal.
