  • Publication number: 20240326193
    Abstract: A rotary body dynamic balance detection and correction device, comprising a detection assembly and a machining correction assembly. The detection assembly is configured to detect the amount of unbalance of a rotary body. The machining correction assembly is configured to machine an outer peripheral face of the rotary body to form a correction hole, so that the value of the amount of unbalance of the machined rotary body does not exceed the value of a preset maximum amount of unbalance. The rotary body dynamic balance detection and correction device can effectively correct the amount of unbalance of the rotary body, reduce the degree of unbalance of the rotary body, and avoid excessive lateral vibration generated when the rotary body rotates at a high speed. A rotary body dynamic balance detection and correction method and a numerical control tool holder are also provided.

  • Patent number: 9302910
    Abstract: The invention relates to a short-flow process for desulfurization of circulating hydrogen and a device for the same. A short-flow process for desulfurization of circulating hydrogen is provided, comprising: (a) removing hydrocarbons from the circulating hydrogen mixture, so that the liquid drops of the heavy hydrocarbons in the dispersion phase are separated from the circulating hydrogen in the continuous phase, and a heavy hydrocarbon phase and a mixture phase of circulating hydrogen containing sulfur are obtained; (b) further separating the resultant mixture phase to remove the sulfides therein, so that circulating hydrogen without sulfur is obtained; (c) further separating the resultant circulating hydrogen without sulfur to remove the amine solution therein, so that purified circulating hydrogen is obtained. The invention also provides a device for desulfurization of circulating hydrogen.
