喷嘴

In some extent, increasing the area of fuel nozzle will be improve the combustion efficiency of DR; 3, the angle between dual air-inlets have complex influence with the combustion of DR.

研究结果表明：(1)补燃室头部距离的增加能增强补燃室头部回流以及提高燃料在补燃室后段分布的均匀性，但也减少了燃料与空气在补燃室后段进行掺混和燃烧的长度：(2)在一定范围内，增加一次燃气喷嘴面积能提高冲压发动机燃料的燃烧效率：(3)进气道夹角对冲压发动机中燃料的燃烧影响复杂，对于采用对称结构喷嘴的冲压发动机，当进气道夹角等于180°时，燃料与空气的掺混效果最好；而对于一次燃气喷嘴采用不同偏心结构的冲压发动机，补燃室内流场与燃料燃烧效率随进气道夹角变化的规律基本相似。

Moreover, looking the nozzle as the important part of the PDC Bit , we deeply discuss the influence of the waterpower parameter and the location parameter influence the PDC Bit, we design the nozzles waterpower parameter.

同时将喷嘴作为PDC钻头水利系统的重要组成部分，深入地讨论了喷嘴的水力参数和位置参数对PDC钻头水力性能的影响，进行了喷嘴的水力参数设计。

The sealant dispenser includes a stage on which a substrate is mounted; a nozzle for dispensing a sealant while making a relative motion with the substrate; a syringe coupled to the nozzle, for storing the sealant; and a distance sensor installed on both sides of a lower portion of the syringe, for measuring a vertical distance between a principal plane of the substrate and an outlet of the nozzle.

密封剂配送器包括其上可安装基板的工作台；用于在相对基板移动的同时配送密封剂的喷嘴；与喷嘴耦合，用于存储密封剂的注射器；和距离传感器，安装在注射器的下部的两侧，用于测量基板的主平面和喷嘴的出口之间的垂直距离。

The schlieren pictures were obtained at different injection pressure,sonic throat height and injector alignment.

采用纹影对天然气/空气流场进行光学显示，得到了不同喷射压力、喉道高度和喷嘴布置(单列6喷嘴和3列18喷嘴)条件下的流场纹影照片。

Solid wimble nozzles are commonly used as flushing nozzles at home and abroad,and the uniformity of spray is one of the important indexes for the performance evaluation of a flushing nozzle.

国内外除雾器冲洗喷嘴一般均采用实心锥喷嘴，均匀度是考核喷嘴性能的重要指标之一。

In other words, although the nozzle is restrained with regard to aftward displacement, the nozzle can potentially displace forward in the motor if a sufficiently large force is applied to the nozzle end.

在其他换言之，虽然喷嘴是克制方面aftward位移，喷嘴有可能取代着在汽车如果一个足够大的力量是适用于喷嘴结束。

Other cause can be vibrations of the print head letting small air bobbles inside the print head preventing the ink head of firing one ore more nozzles, also change of cartridges can let a little bit of air inside the ink system, in case of missing nozzles it will look like white line within the print, then push the pump bottom for a few seconds, please have a JetMaster tissue in front of the head when using the pump, otherwise you are facing ink all over your machine, the ink can spray more than one meter out of the print head using this function, so please use it carefully.

喷印头的振动释放的小茸球在喷印头中阻塞喷头的一个或多个喷嘴的射击，同时和的变化会使一点空气进入油墨系统，避免喷嘴的缺失。然而当喷嘴丢失时，喷印看起来像白线，这时推动操作泵底部数秒。请在顶端前有Jet Master棉纸时，使用操作泵，否则油墨会溅到机器上，可溅出喷印头1米多。因此，请谨慎使用。

In order to study the pressure-swirl nozzle's atomization characteristic, the particle diameter distributions along axis of the nozzle have been measured by immerging.

摘要为了研究一种高压静电压力旋转喷嘴的雾化特性，采用浸入法测量了该喷嘴喷雾雾滴粒径在喷嘴轴向的分布状况。

The nozzle of the gasifier is simplified. The cold-flow field in the gasifier chamber is studied. The research shows that the chamber has recirculation along the whole length. The particles in the chamber perform a very good flowing characteristics even for the large particles of dp=150μm, and no abrupt change is observed. This is due to the operational pressure is high and the density of the gas is large there. The maximal reflux velocity of both phases, the reflux intensity, the concentrational distribution of particles, and the static pressure loss in the chamber are all related to following factors: the load of gasifier, the concentration of coal-water slurry, the diameter of the coal particle, the distribution ratio of oxygen in the two channels of the nozzle, and the angle of jet in nozzle.

本文对水煤浆气化炉喷嘴进行了简化处理，在此基础上，对气化室内的冷态流动过程进行了研究，发现：整个气化室都处于流动的回流区长度范围以内；水煤浆气化炉中，由于操作压力很高，气相密度很大，所以即使对于dp=150μm的较大煤颗粒，其对流体的跟随特性也很好，没有发生流动特性突跃的现象；两相的最大回流速度、回流强度，颗粒相的浓度分布，以及气化室内的静压力损失等，均与气化炉的负荷、水煤浆浓度、煤粒直径、O2在喷嘴两个流道中的分配比例、以及喷嘴的射流角等参数有关。

Plunder melds and run with this jewel!
