發射管電性能測試方法共柵電路靜態特性曲線的測試方法Measurements of the electrical properties of transmitting tubes - measuring methods of static characteristic curve for common cathode circuit
發射管電性能測試方法共陰電路靜態特性曲線的測試方法It is indicated that, when a two - speed motor is used for driving oil transfer pump, the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance, and its speed control range is restricted by the pipeline resistance characteristic curve, the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel, the pump with better performance should be changed into speed - variable pump
指出雙速電動機用於輸油泵的調速時,應選用轉矩按轉速平方降低特性的電動機;調速泵的運行經濟性受到管路阻力特性曲線的限制,其調速范圍受到管路阻力特性曲線、系統所需揚程和泵運行特性的限制;在母管制系統中把部分定速泵改為調速泵時,應將性能較高的定速泵改為調速泵。This paper designs the characteristic curves and system curves for the dredging materials of the water and all kind of mixtures, which base on the theory of hydraulic dredging and the experiment data of prototype dredger, then puts out the equations of computing the work point of dredge pump system and the model that can simulate the work condition of dredging pump such as the flow rate, vacuum and pressures
該模型根據水力疏浚原理和1750挖泥船的技術數據,設計了泥泵和管路的清水特性曲線與泥漿特性曲線,在此基礎上給出了泥泵工作點的計算方法。最後給出了計算泥泵工況的模型和模擬實例; 3 、絞刀電動機拖動系統。Rotating pipes system are often encountered in the rotary machinery of engineering applications. with the popularity of rotary machinery in industry, the characteristics of the fluid flow and heat transfer in the controlling pipe system, the transporting pipe system, and the cooling pipe system are the main factors to improve the efficiencies of the rotary machinery. meanwhile, when a man is in the aerocraft with a high rotating speed or in the rotating machine for training, the flow in the blood vessel of body will change evidently and so the study on the flow in the blood vessel also becomes the important research field in the aerial - physiology
在旋轉狀態下,這些曲線管路系統中的流動和換熱特性將會發生什麼樣的變化,是對管路系統的性能以及旋轉裝置的運行安全至關重要的問題,也是管道流動中研究很少,又是迫切需要解決的課題;同時,這個課題還可以應用於生物流體力學:當人體處于作高速旋轉或曲線運動的飛行器或宇航飛行員訓練的旋轉裝置中,人體血管內血液流動將會發生什麼樣的變化,是航天生理學研究的重要課題。According to the load and pipeline characteristics of heating systems, puts forward the principle of selecting circulating water pumps and the fitting method of characteristic curves
