Study on Carbon Dioxide Air Conditioning Cycle with an Expander 带膨胀机的CO2空调系统循环的研究
Assistant air of certain pressure is necessary to assure the good performance of start and stop of bearings. The assistant pressure can be arranged from 0.1 MPa to 0.2 MPa when the self-acting gas-lubricated thrust bears work with an expander. 一定压力下的辅助供气是全动气体止推轴承具有良好的起停性能的重要保证,对于透平膨胀机采用的全动压气体止推轴承,供气压力在0.1~0.2MPa之间。
The paper introduces the liquefaction principle and operating features of nitrogen expansion using an air expander associated with an air separation unit. 介绍了利用空分设备空气膨胀机进行氮气膨胀液化的原理和操作特点;
Study on cooling air allocation and expander power calculation of large scale gas turbine 大型燃气轮机冷却空气量分配及透平膨胀功计算方法研究
A small cold air refrigerator based on the reverse Brayton cycle is developed, and a new type of foil journal bearing is used in the turbo expander which is the key component of cold air refrigerator. 设计了一台小型透平逆布雷顿循环空气制冷机,并将一种新型的箔片径向气体轴承应用在该制冷机系统的透平膨胀机上。
By using PLC programming technology and completed tripled redundant fault-tolerance hardware, the system has been applied successfully in Yumen Refinery FCCU main air blower and Expander control, and the efficiency was very well. 该系统在玉门炼油厂重油催化装置主风机及烟机控制方面获得了成功应用,取得了显著的经济效益。
Theoretical analysis of the thermal performance of opening reverse-Brayton air refrigerator has been performed. A model of refrigerator system consisting of compressor, expander and exchanger has been set up. 针对开式逆布雷顿循环空气制冷机的热力性能展开理论分析,建立压缩机、膨胀机和回热器3大部件的制冷机系统模型。
Vibrations in the coupled main air blower flue gas expander of FCCU of Yueyang General Petrochemical Works were so heavily beyond the standard values due to imperfect alignment of the units, even reached 120 μ m. 岳阳石油化工总厂催化裂化装置主风机烟气轮机机组联动试车时主风机振动值严重超标(达120μm),根本原因是机组对中不良。
