    摘要： A geared compressor includes a drive gear, a first intermediate gear, a second intermediate gear, a first impeller and a second impeller connected to a first driven gear, and a third impeller and a fourth impeller connected to a second driven gear. When viewed from an axial direction, a drive axis of the drive gear is disposed below a first intermediate axis of the first intermediate gear, a second intermediate axis of the second intermediate gear, a first driven axis of the first driven gear, and a second driven axis of the second driven gear in a vertical direction. The first impeller has a larger outer diameter than the second impeller, the third impeller, and the fourth impeller.

    摘要： A compression system includes a compressor that compresses a synthesis gas to produce a compressed gas, a first line that supplies a first gas constituting the synthesis gas to the compressor, a second line that supplies a second gas constituting the synthesis gas to the first line, a discharge line that circulates the compressed gas, a recirculation line that recirculates a part of the compressed gas from the discharge line to the first line, a first regulating valve arranged in the first line, a second regulating valve arranged in the second line, a discharge valve arranged in the discharge line, a recirculation valve arranged in the recirculation line, and a valve control device that performs switching between the first regulating valve, the second regulating valve, the discharge valve, and the recirculation valve based on an operation condition of the compressor.

    摘要： Compressor rotor structure for turbomachinery, such as a compressor, is provided. Disclosed embodiments may involve a flow loop that at least in part flows through the interior of the tie bolt or by way of a venting arrangement that at least in part extends through one of the rotor shafts of the rotor structure. Disclosed embodiments may further benefit from seal elements that may be arranged to inhibit passage onto respective hirth couplings of the process fluid being processed by the compressor. In operation, the flow loop may be appropriately pressurized to keep any residual seal leakage that may develop in one or more of the seal elements from travelling onto the hirth couplings

    摘要： A turbo compressor is disclosed. The turbo compressor may have an assembly-type rotational shaft where a permanent magnet is inserted into a connecting sleeve, at least one first locking projection formed on either an inner periphery of the connecting sleeve or an outer periphery of the permanent magnet facing the inner periphery of the connecting sleeve, and at least one first locking groove formed on the other. Thus, the permanent magnet constituting a rotor may be easily coupled into the rotational shaft, and the permanent may be effectively prevented from slipping. Moreover, a magnet embedded in the rotational shaft may be securely fixed so that it is held in a position where it is assembled, thus providing an advantage in concentrically aligning the magnet.
