Title: Innovator Nobuhiro Kunitake: Pioneering Oil Field Pump Technology

Introduction: Nobuhiro Kunitake, an accomplished inventor based in Takasago, Japan, has made significant contributions to the field of engineering, particularly in oil extraction technology. With a total of seven patents to his name, Kunitake stands out for his innovative designs and engineering prowess.

Latest Patents: Among Kunitake's notable inventions is an advanced oil field pump. This pump is ingeniously designed to be installed within a pipe that connects to an oil field, facilitating the efficient movement of accumulated extraction oil in a specified direction. The oil field pump features a rotor equipped with an internal flow path for the extraction oil, complemented by a stator mounted on the rotor's outer circumference. Additionally, it includes a thrust bearing, which bears the axial weight of both the rotor and stator. A supply pipe is strategically placed to deliver a portion of the extraction oil to the thrust bearing, while a filter upstream ensures that foreign matter is trapped, maintaining the system's integrity.

Another version of the oil field pump similarly boasts efficient design elements, including the rotor, stator, and the intricately developed flow path that connects the interior of the rotor to the annular space formed between the rotor and the stator. The inclusion of a thrust bearing, which has a protrusion fixed to the rotor, reveals Kunitake’s detailed attention to the mechanics involved in oil extraction systems.
