spraying angle 中文意思是什麼
spraying angle
解釋
噴射角-
Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high
通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析，得到：撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角，噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高，撞針型結構提高了霧化加濕效率，高壓小孔徑的特點為霧化加濕提供了較大的能量，而噴水初溫的升高會減小水的粘性力和表面張力，從而優化加濕效果。 -
Using fem ( finite element method ), the paper makes mechanical analyses on bench cut method and side heading method, it also makes mechanical analyses on some auxiliary construction methods, such as big pipe - roof protection, horizontal roll - spraying, big and small angle pipe - roof protection and surface grouting
論文採用有限元的分析方法，主要對臺階法、側壁導坑法進行了力學分析，也選擇了大管棚法、水平旋噴法、大小外插角管棚法和地表注漿加固四種輔助工法進行力學分析。 -
It can make sprinkler of water feeding install on strap or on sand inlet of double disk and adjust spraying angle of sprinkler according to real condition ; the water will spray on falling sand that makes it form sand curtain ; it sprays water on hot sand equably and extends exchanging time of water and hot sand. 4
根據現場情況，加水噴頭可設在進砂皮帶上，或設在雙盤的進砂口處，調整噴頭的噴灑角度，使水噴向由下落的砂子組成的砂簾，將水盡可能預先均勻得噴灑在熱砂上，增加水與熱砂的有效熱交換時間。 -
( 2 ) base on the analysis of the atomizing principles of spray nozzle, mathematical model of combined spin - flow pressure spray drying was set up and the essential parameters such as spraying pressure, liquid quantity, temperature, spraying angle, inject distance, particle diameter and distribution, hollow diameter for several materials in normal conditions by experiment and ldv
（ 2 ）對旋流式組合壓力噴嘴噴射霧化機理加以分析，建立了旋流式噴嘴霧化的數學模型，採用冷態試驗法並藉助激光霧滴測試等實驗裝置對噴嘴的霧化參數（如霧化壓力、噴液量、料液溫度、霧化角、霧距、霧滴直徑和分佈以及噴嘴的空芯半徑等）進行測量和計算。 -
( 4 ) the droplets diameter of the combined spin - flow pressure spray drying are between 30um and 150um and the ranges of the droplets are narrow. the average diameter of the droplets is between 50 um and 100 um and the spraying angle can be adjusted from 30 to 180
（ 4 ）採用旋流式組合壓力噴嘴霧化后的液滴直徑大都分佈在30 150um之間，霧滴分佈范圍較窄，其霧化的平均液滴直徑在50 100um左右，壓力噴嘴的霧化角度可在150 180范圍內。 -
For instance : nowadays use the small and exquisite paint - spray robot abroad, can scan the size of specification of the work piece and programme by oneself automatically, whole craft circulation go on in succession, according to accurate to is it stock give speed to control procedure have, all parameters of spraying paint in the angle and distance etc., use the painting amount to obviously reduce
如：當今在國外使用小巧的噴漆機器人，能自動掃描工件的規格尺寸並自編程序，整個工藝循環連續進行，按程序精確控制進給速度噴漆角度和距離等所有參數，用漆量明顯減少。
