摘要: A pumping system configured to recover wellbore fluids from a wellbore includes an electric motor that has a motor head, a pothead receiving bore within the motor head, a motor insulator block within the motor head, and a stator lead within the motor insulator block. The pumping system further includes a motor lead cable and a pothead connector connected between the motor head and the motor lead cable. The pumping system includes a hermetically fused pothead-to-motor connection at an interface between the pothead connector and the motor head that obviates the need for conventional elastomeric seals at the interface between the pothead connector and the motor head.

摘要: A seal mechanism for an electric submersible pump (ESP) assembly comprising a graphite ring installed on a first component with an installation configuration and a sealing configuration. The graphite ring is installed on an external sealing surface of a first component. An internal sealing surface of a second component is aligned with the graphite ring. An activation force transitions the graphite ring from the installation configuration to a sealing configuration wherein the graphite ring forms a seal to the external sealing surface of the first component and the internal sealing surface of the second component.

摘要: A recirculation pump includes an impeller, a pump motor assembly, and a heater. The pump motor assembly includes a pump housing having a pump cavity and a pump motor arranged in the pump cavity that drives the impeller, the pump housing arranged axially away from the impeller. The heater is disposed on or in the pump housing and spaced apart from the impeller. The heater is configured to increase a temperature of any portion of the fluid that leaks from the impeller into the pump cavity and resides in the pump cavity. The increase in the temperature causes the fluid that resides in the pump cavity to flow toward the impeller and exit the pump cavity.

摘要: Disclosed is a self-priming fluid transfer system having an integral siphon line that draws trapped air bubbles out of a main fluid chamber over time and fluid cycles. The self-priming fluid transfer system may include a body structure and a siphon line. The body structure may include a chamber inlet and a chamber outlet. The main fluid chamber may receive and output fluid from the chamber inlet and the chamber outlet, respectively. The siphon line may be positioned at the periphery of the main fluid chamber and may include a priming inlet and a siphon outlet. The priming inlet may be positioned at or near a top wall of the body structure and may receive air bubbles from the main fluid chamber. The siphon outlet may be positioned at the chamber outlet and may output the air bubbles at the chamber outlet. Other examples may be described and claimed.
