  • Agitator drive
    Patent number: 6698934
    Abstract: A drive for powering an agitator in a chemical process vessel may be located inside a housing attached to the vessel and may have a motor that drives a shaft that is attached to an agitator assembly inside the vessel. The shaft may pass into the vessel through a floor in the housing, which may be provided with a standpipe to prevent the flow of fluid on the floor into the vessel. A shield attached to the shaft may be provided above the standpipe to prevent fluid from entering the standpipe from above. In addition, a sump may be provided to allow effective lubrication and cooling for bearings that support the shaft.
    Type: Grant

    Date of Patent: March 2, 2004
    Assignee: ConocoPhillips Company

  • Hydraulic motor for use in high-pressure environment
    Patent number: 6685358
    Abstract: A hydraulically operated motor may be located in an atmosphere having substantially high and varying pressure. The motor may be provided with conduits that are in fluid communication with cavities adjacent to the motor bearings, so that fluid in the conduits may lubricate the bearings. Lubricating fluid may be introduced to the conduits across an air gap that is in the atmosphere having substantially high and varying pressure, and the fluid may thereby pass through and lubricate the bearings.
