摘要： PURPOSE:To try to stabilize a thrust bearing by supplying fluid from a compressor outlet nozzle to the thrust bearing and enabling load to the thrust bearing to be increased according to thrust power which increases with rise of a turbine inlet pressure. CONSTITUTION:Turbine process gas flowing in from a compressor inlet 1 is pressurized in a compressor impeller 2 and a compressor casing 3 in order to flow out from a compressor outlet nozzle 4. And, said turbine process gas, after passing through a conduit 21 and being cooled in an after cooler 5, goes through a conduit 22, a turbine inlet valve 6, a turbine inlet nozzle 7 and an injection hole nozzle 8, and is adiabatically expanded at a turbine impeller 9 in order to flow out from a turbine outlet nozzle 10. A part of gas, having been pressurized at the compressor impeller 2 and the compressor casing 3, goes through a check valve 13 in order to be supplied to a thrust bearing 15 by means of bearing pressure corresponding to rise of turbine inlet pressure.

摘要： PURPOSE:To prevent burning of bearing due to abnormal drop in bearing unit temperature by detecting the temperature and increasing supply of seal gas at least when the detected value drops less than the set temperature. CONSTITUTION:High pressure process gas 7 expands adiabatically when passing in a nozzle 6 and an impeller 1 to become low pressure and low temperature gas, and the power generated this time is transmitted by a shaft 3. While, low temperature gas passing a nozzle outlet 4 and leaked from the back face of the impeller 1 passes through labyrinthes 4, 5 to be flowed to the side of bearings 2a, 2b. To prevent leak of low temperature gas, seal gas is supplied between the labyrinthes 4, 5. This time, the upper limit and the lower limit of the temperature of the bearing 2a unit is detected by a detector 9 and if the temperature is at the lower limit of the set value, a seal gas adjusting valve 10 is opened. Then, supply of seal gas is increased to prevent bad effect due to low temperature high pressure gas.
摘要翻译：目的：通过检测温度和增加密封气体的供应，至少在检测值下降到低于设定温度时，防止轴承单元温度异常下降导致轴承燃烧。构成：高压处理气体7在通过喷嘴6和叶轮1时绝热膨胀成为低压和低温气体，此时产生的动力由轴3传递。而低温气体通过喷嘴出口 4并从叶轮1的背面泄漏通过澄清物4,5流动到轴承2a，2b的侧面。为了防止低温气体的泄漏，在密封圈4,5之间提供密封气体。此时，轴承2a单元的温度的上限和下限由检测器9检测，如果温度在设定值的下限，打开密封气体调节阀10。然后，增加密封气体的供给，以防止由于低温高压气体引起的不良影响。

摘要： PURPOSE:To enable to easily adjust a clearance between a pad and a pivot, in a main rotary shaft supported by a pad, by supporting the pad by a pivot so as the pad can oscillate and by connecting a load-applying device and a movable spacer in series to the pivot. CONSTITUTION:A main shaft 1 is supported by a pad 2, and the pad 2 is supported by a pivot 3 so that the pad can oscillate. The pivot 3 can freely move in the radial directions of the main shaft 1 in a bearing housing 7, its head comes to contact with a plate spring 13 attached to the bearing housing 7, and a reverse load is applied to the pivot 3 by clamping a screw 12 of the plate spring 13. Further, a spacer 10 is inserted between the bearing housing 7 and the plate spring 13, and the spacer 10 can move by clamping its screw 11. As a result, an initially set clearance 5 can finally be freely adjusted in a state where the plate spring 13 and the pivot 3 are apart from each other. Thus, a small clearance between the pad 2 and the pivot 3 can be easily adjusted and the starting characteristic can be improved.

摘要： PURPOSE:To always keep bearing oil in a prescribed amount by providing a self- actuated pressure regulating valve at a damping inlet and supplying oil to the damping circuit via a differential pressure regulating valve, in an expansion turbine with a damping system provided with a centrifugal radial flow impeller for an oil pump. CONSTITUTION:An impellet 2 assembled into an expansion turbine 1 is provided to construct a control circuit in a closed form as well as an oil cooler 6 and a control force regulating valve 13, and a bearing is oiled by raising the oil pressure in an oil tank 9 by means of an oil pump 4. On the other hand, exhaust oil is permitted to flow into a separator 15 together with leakage gas from the expansion turbine 1 side and the gas is discharged via a pressure regulating valve 16, while the oil is returned to the oil tank 9 via a pressure regulating valve 14. Further, oil to the damping circuit is supplied by partly extracting oil from a bearing oiling line and adjusting its flow rate with a differential pressure regulating valve 10 which is controlled by a differential pressure converter 11. Moreover, pressure at a damping inlet is kept constant by a self-actuated pressure regulating valve 12.
