  • Publication number: 20190309765
    Abstract: Systems and method for operating a gas compressor are disclosed herein. A compressor can have one or more dry gas seals surrounding the central axle of the compressor. The dry gas seals can each be pressurized with a barrier gas or other fluid supply providing a barrier within the dry gas seal. The method can include controlling delivery of a first barrier gas to the one or more dry seals during a startup or initiation of the compressor. The method can include controlling delivery of a second barrier gas different from the first barrier gas to the one or more dry seals based on the information received from sensors disposed within the compressor that can measure, inter alia, dry seal temperature and pressure within the system. The method can further include terminating the delivery of the first barrier gas based on the sensor information.

  • Patent number: 9616491
    Abstract: The invention provides a split-type mold for wheel casting, the mold having an upper die, a split-type water-cooling side die and a lower die, and the split-type water-cooling side die is divided into four pieces along a circumferential direction of the wheel mold. A thermal deformation arc compensation surface is machined on ¼ arc portion of each split-type water-cooling lower side die, and a compensation surface is machined on key portions of 45-degree matching surfaces of adjacent split-type water-cooling upper side dies. The side die can effectively solve the problems such as untight matching between the matching surfaces, flashes of the matching surfaces and aluminum sticking and the like due to the thermal deformation and non-homogeneous expansion and shrinkage of the two portions of the split-type water-cooling side die.

  • Patent number: 9604277
    Abstract: The present invention provides an integrated mold for casting of wheels. The integrated mold has an upper mold, integrated side molds and a lower mold, wherein the number of the integrated side molds is four in the circumferential direction of the wheel mold. Thermal deformation circular arc compensation surfaces are formed by processing on an upper and lower one-fourth circular arc part of each integrated side mold, and compensation surfaces are formed by processing on key parts of 45-degree matching surfaces of the adjacent integrated side molds. The integrated side molds can effectively solve the problems such as imprecise matching of the matching surfaces, parting-line flashes of the matching surfaces and adhesion of aluminum caused by thermal deformation of the integrated side molds.
