  • Patent number: 12218508
    Abstract: An electrical generator that is configured to simultaneously output different types of electrical power so that electrically powered components that require different types of electrical power can be simultaneously powered by the electrical generator. The electrical generator can be used at any location where electrically powered components that require different types of electrical power are utilized. Instead of or in addition to outputting different types of electrical power, the electrical generator can also be configured to output at least one type of electrical power as well as a cooling liquid for use in cooling an external heat generating component.
    Type: Grant

  • Patent number: 11208859
    Abstract: A pit pump of a drilling fluid recycling system where the pit pump is driven by a liquid cooled electric drive motor that is cooled by a cooling liquid. The pit pump can stay submerged in the used drilling fluid within the pit indefinitely since the pit pump does not require cleaning to remove caked on drilling fluid to prevent overheating of the electric drive motor since the cooling liquid cools the electric drive motor. This reduces or eliminates the need to remove the pit pump from the pit for servicing. The electric drive motor can also be reversible to reverse the rotation direction of the pit pump. Further, the pit pump can include its own controller, located within the pit or outside the pit, connected to various sensors that can be used for health monitoring of the pit pump and controlling operation of the pit pump.
