Patent number: 11946476Abstract: The present disclosure provides a compressor rotor, a compressor and a refrigerant circulation system. The compressor rotor includes: a motor rotor including a plurality of rotor sections, a locking rod, a compression unit rotating part and a locking member. The rotor sections are fixedly connected in an axial direction and are provided with an axial through hole and the locking rod penetrates through the axial through hole. The compression unit rotating part is located at the end part of the motor rotor and is connected to the locking rod. The locking member is configured to lock the compression unit rotating part on the locking rod. The locking rod, the compression unit rotating part and the locking member form a pressing structure which applies a pressure toward an axial inner side to the motor rotor.Type: GrantFiled: October 23, 2019Date of Patent: April 2, 2024Assignee: Gree Electric Appliances, Inc. of ZhuhaiInventors: Hua Liu, Zhiping Zhang, Yuhui Chen, Ruixing Zhong, Hongbo Li, Wenteng Ye, Jingli Qi

Patent number: 10851814Abstract: A valve signature diagnosis and leak testing device includes a spool valve operatively connected to a pilot valve, the pilot valve being configured to position the spool valve to one of an open position and a closed position. A blocker valve is fluidly connected to a control fluid outlet of the spool valve. An electrical module is operatively connected to the pilot valve, a supply of control fluid, and the blocker valve, the electrical module being capable of sending pulsed electrical signals to the pilot valve and the blocker valve to selectively position the spool valve and the blocker valve to an open or closed position.Type: GrantFiled: July 8, 2019Date of Patent: December 1, 2020Assignee: General Equipment and Manufacturing Company, Inc.Inventors: Bruce R. Penning, Jingli Li, Bruce Rigsby, Robert L. LaFountain

Patent number: 9471049Abstract: A system and method for configuring a field device of a control system is provided. The system includes a mobile computing device for communicating with a wireless adapter coupled to the field device. The mobile computing device receives an application module via a wireless network communication module. The application module, when executed by a processor, configures the field device via a wireless direct communication module. The mobile computing device includes a user-friendly graphic display to provide and receive information associated with the configuration of the field device.Type: GrantFiled: December 19, 2012Date of Patent: October 18, 2016Assignee: General Equipment and Manufacturing Company, Inc.Inventors: Jingli Li, Charles E. Griffin

Patent number: 8814133Abstract: An automatic speed searching device for a partial stroke test of a control valve includes a spool valve operatively connected to a pilot valve and a blocker valve. An electrical module is operatively connected to the pilot valve, a supply of control fluid, and the blocker valve. In an open position of the spool valve, a first control fluid inlet is fluidly connected to a first control fluid outlet, and in a closed position of the spool valve the first control fluid outlet is fluidly connected to a second control fluid outlet. A method of determining an optimum stroke speed includes iteratively powering a main and secondary solenoid in the electrical module and updating parameters to move a control element of the control valve until movement of the control element is within a desired range.Type: GrantFiled: June 23, 2011Date of Patent: August 26, 2014Assignee: General Equipment and Manufacturing Company, Inc.Inventors: Jingli Li, Bruce Rigsby, Robert L.
