  • Pump body assembly, heat exchange apparatus, fluid machine and operating method thereof
    Patent number: 11971031
    Abstract: The present disclosure provides a pump body assembly, a heat exchange apparatus, a fluid machine and an operating method thereof. The pump body assembly includes a piston, a shaft, a piston sheath, and a cylinder. The shaft drives the piston to rotate and reciprocate within the piston sheath while rotating. The piston sheath is located in the cylinder, and a compression chamber is defined between an outer circumferential wall of the piston and an inner wall of the cylinder. A pressure relief recess is defined in the outer circumferential wall of the piston or the inner wall of the cylinder at a position corresponding to the compression chamber.

  • Method and system for data synchronization
    Patent number: 7899935
    Abstract: A data synchronization system and method. The method includes that when a change happens in a source application, data is collected from a source application based on a target application subscribing the source application and collection data is transmitted to the target application or is directly inserted to target database. The system includes data collection unit and distribution unit. The present invention may realize synchronization on demand, simultaneously reduce greatly synchronous data quantity, decrease network load, and guarantee smoothness and stabilization of network. The present invention applies to data synchronization of enterprise internal/external data systems, telecommunication networks, etc.
