(续上) 3 特殊设备的危险性空分设备中输送氧、氮的机械设备和产品氧的输送系统都要求特别的考虑。因为氧气能助燃,部件的清洁对于空分设备的安全是至为重要的。易燃物不能存在已知着火源的系统中,而氧压机、液氧泵、氮压机和氧管道系统都是存在着火源的设备。 3.1 离心式氧压机在离心式氧压机内,能量用于增加系统中的压力,部件在很高的速度下相对运动,而且间隙很小。旋转部件的平衡和稳定是很关键
(Cont’d) 3 Special Equipment Hazards Special considerations are required for the delivery of oxygen and nitrogen to mechanical equipment and products in air separation plants. Because oxygen helps combustion, the cleaning of components is crucial to the safety of the air separation plant. Flammable substances can not exist in the system of known sources of ignition, and oxygen compressor, liquid oxygen pump, nitrogen compressor and oxygen pipeline system are the existence of a source of ignition equipment. 3.1 Centrifugal oxygen compressor In a centrifugal oxygen compressor, the energy used to increase the pressure in the system, the relative movement of components at high speed, and the gap is small. The balance and stability of rotating parts is crucial
