Spray nozzles are designed to perform under various operating conditions. The following characteristics should be considered when selecting a nozzle:〔A.H. Lefebvre'', Atomization and Sprays'', 1989, ISBN 0-89116-603-3〕 * Spray Pattern * Capacity * Spray impact * Spray Angle * Drop Size == Spray Pattern == Selecting a nozzle based on the pattern and other spray characteristics that are required generally yields good results.〔Lipp, Charles W. , Practical Spray Technology: Fundamentals and Practice , 2012, ISBN 978-0-578-10090-6〕 Since spray nozzles are designed to perform under many different spraying conditions, more than one nozzle may meet the requirements for a given application. Surfaces may be sprayed with any pattern shape. Results are fairly predictable, depending on the type of spray pattern specified. If the surface is stationary, the preferred nozzle is usually some type of full cone nozzle, since its pattern will cover a larger area than the other styles. Spatial applications, in which the objective is not primarily to spray onto a surface, are more likely to require specialized spray characteristics. Success in these applications is often completely dependent on factors such as drop size and spray velocity. Evaporation, cooling rates for gases and solids, and cleaning efficiency are examples of process characteristics that may depend largely on spray qualities. Each spray pattern is described below with typical end use applications. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Spray characteristics」の詳細全文を読む スポンサード リンク
