摘要： A bearing device for supporting a rotating shaft substantially arranged in a vertical direction in a vertical rotation machine is disclosed. The bearing device enables the vertical rotation machine to operate in a stable and contamination-free condition by preventing leakage of lubricant as well as to decrease the lubricant consumption. The bearing device comprises a roller bearing for supporting the rotating shaft and a labyrinth seal provided below the bearing. An oil dam is provided at a bottom portion of a bearing chamber to surround the sealing. An oil suction pipe for discharging lubricant from the oil dam, a sealing gas supply passage for supplying sealing gas into the bearing chamber from below by way of the sealing, and a sealing gas vent port opening at an upper area of the bearing chamber are provided.

摘要： A self-contained liquefied gas supply system has a tank for storing a liquefied gas, a primary pump for delivering the liquefied gas from the tank, a secondary pump for pressurizing the liquefied gas delivered from the primary pump, a vaporizer for vaporizing the liquefied gas discharged from the secondary pump into a vaporized gas, an expander for actuating the secondary pump with the vaporized gas produced by the vaporizer, and a back-pressure line connected to an outlet of the expander. A bypass pipe is connected between the primary pump and the vaporizer in bypassing relation to the secondary pump for supplying the liquefied gas from the primary pump to the vaporizer. A joint line is connected between the back-pressure line and a substantially atmospheric pressure line, the joint line having a first flow regulating valve for regulating a rate of flow of a gas from the back-pressure line to the substantially atmospheric pressure line. A bypass line is connected between the vaporizer and the back-pressure line in bypassing relation to the expander, the bypass line having a second flow regulating mechanism for regulating a rate of flow of the vaporized gas from the vaporizer to the back-pressure line. For starting the secondary pump, the liquefied gas is delivered from the primary pump through the bypass pipe to the vaporizer, which produces a vaporized gas supplied to the expander.

摘要： PROBLEM TO BE SOLVED: To provide a remote monitoring system suitable for a dispersively arranged device, by operating at a high speed like a micro-turbine cogeneration system. SOLUTION: This diagnostic method of the system is provided for monitoring normalized data on whether or not there is an irregular change along a time base, by normalizing at least two measuring data based on the predetermined relationship, by storing its measured data, by measuring at least the two measuring data put in the predetermined relationship. The predetermined relationship is the relationship expressed by the linear relationship or approximated by the linear relationship on the relationship of a measuring object of at least the two measuring data.
