Title: The Innovative Contributions of Long Ran
Introduction
Long Ran is a notable inventor based in Chengdu, China. He has made significant strides in the field of oil drilling technology, particularly with his innovative all-metal intelligent control motor. His work has implications for enhancing drilling efficiency and reducing costs in deep well exploration.
Latest Patents
Long Ran holds a patent for the all-metal intelligent control motor (AMIM). This invention comprises an electric control module, a power module, and a transmission module. The electric control module utilizes an electromagnet to determine the axial position of the connecting rod valve. It controls the connection between the connecting rod valve and the piston through an electric motor. The hydraulic pressure of drilling fluid, along with the spring reaction force in the power module, enables a double worm to move axially and circumferentially. This movement is facilitated by internal teeth on the inner surface of the shell. A one-way bearing ensures that the power module transmits unidirectional motion only. The transmission module limits the power module axially through TC bearings and transmits circumferential motion, drilling pressure, and torque to the lower drilling tool. The AMIM is designed for various deep well exploration applications, offering stronger drilling force, lower costs, and higher applicability.
