Fundamental technical requirements for large and medium inlet valves of hydraulic turbine GB/T14478-1993大中型水轮机进水阀门基本技术条件
Working medium inlet and exhaust non-return valves balance hole for Stirling engine is introduced. 对热气机工质进排气单向阀平衡孔作了简介。
It is therefore very necessary to consider the sensitivity of fixed bed reactors to cooling medium flow rate and inlet temperature variations of colling medium for design and control of highly exothermic catalytic gas phase reactions on an industrial scale. 因此对于强放热反应过程,考虑反应器对冷却介质的流量和进口温度的参数灵敏性对反应器的设计和控制是必要的。
Abstract On the basis of analysis of inner flowing field medium and small type centrigugal main fans a direct measuring method with total pressure tube and static pressure sensor located at the cross section of fan inlet is proposed for the dynamic behavior of main fans. 在对中小型离心式主要通风机内部流场分析的基础上,提出了在主要通风机入口断面布置全压管、静压感压器直接测量主要通风机气动性能的方法。
Analyzes in detail the performance features and various economic indexes of barotropic direct fired systems with medium speed pulverizers and double inlet and outlet tube mills separately. 详细分析了中速磨煤机正压直吹式制粉系统和双进双出钢球磨煤机正压直吹式制粉系统各自的性能特点和各项经济指标。
The effect of absorptive coefficient of the outer layer medium on the coupled heat transfer is similar to that of the radius ratio of two layers in the inlet cross section. 外层介质的吸收系数、入口截面的相对厚度对耦合换热的影响基本一致;
The results show that the suspension whirl field and separation area are determined by medium inlet diameter and shape, the flow ratio and separation density are determined by heavy product outlet. 研究结果表明:旋流器的介质入口口径和形状决定了旋流器内悬浮液涡旋场和物料分选区域的范围;重产物出口面积决定了旋流器的分流比和分选密度。
Oxygen transfer rate, with water as the medium in the tests, was augmented with increasing water flow rate and gas flow rate, and with decreasing inlet oxygen concentration in water. 通过水中的氧气传递实验发现,IVOX的氧合能力随水流量、氧气流量的增加而增加,进口氧浓度越低,氧合效率越高。
