In this paper a general flow diagramm of the HAR.SJ-300 feed processing combination was shown. The combination consisted of a hammer mill and a vertical screw type mixer, they could be installed in one unit or separately. Therefore the field of application could be expanded.The result of mathematical analysis pointed out that it is necessary to et a serrated plat in the top of the grinding chamber for breaking the material layer which moves near the screen and promoting partical size reduction.After a series of tests, it was proved that the efficiency of the hammer mill could be increased by 11.2%. Through airing the central part of the grinding chamber by an air-assisted system the efficiency of the hammer mill enhanced by 11.3%.After a series of tests of the vertical screw mixer the following conclusions were obtained:1. As the time goes on the variation coefficient CV of the mixed material was rapidly decreased, 4 seconds later, the value of CV becomes less than 10%.2. The mixer of the combination had been tested with different rotating speeds at 420rpm, 320rpm and 220rpm. The results showed that 320rpm was the more preferable speed.3. Wilcox (1981) recommended that a well-designed single screw vertical mixer should be run in a minimum time of 15 minuts after the last ingredient was added. But the results of our tests showed that if the structure parameters of the mixer was selected properly the quality of the mixing feed would get an optimum result in 6—8 minutes.

本文给出了哈SJ-300型饲料加工机组的工艺流程,该机组主要由粉碎和混合机组成,装在一起成为一个机组,两台设备可以各自单独作业,以扩大机组的适用范围。文章指出,在粉碎室内加截击板可破坏粉碎室内环流层,增进粉碎效果,度电产量提高11.2%。向粉碎机的粉碎室内增加通风,粉碎机性能得到改善,度电产量可增加11.3%。机组的混合机经试验得出如下结论: 1.随着混合时间的延长,混合物的变异系数CV值迅速下降,4分钟后CV值稳定在10%以下。2.混合机的3种转速(420、320、220转/分)做了试验。试验表明,以320转/分为最好。3.该机组从最后一种成分物料加入算起,只需运转6~8分钟。

A novel hand-operated mist-blower, the HANDIMIST , had been developed: following twin-fluid atomisation method. With a specially designed annular jet pneumatic energy nozzle the water-based spray mixture could be dispersed into a fine mist with a VMD value of 50-100 μm under an air pressure as low as 0.03 MPa. The air-assisted spray cloud has a narrow-angled solid cone holding a spray angle of 25°-30°. The flow-rate of spray mixture is adjustable between 0-120 mL/min, and the application rate of spray mixture...

A novel hand-operated mist-blower, the HANDIMIST , had been developed: following twin-fluid atomisation method. With a specially designed annular jet pneumatic energy nozzle the water-based spray mixture could be dispersed into a fine mist with a VMD value of 50-100 μm under an air pressure as low as 0.03 MPa. The air-assisted spray cloud has a narrow-angled solid cone holding a spray angle of 25°-30°. The flow-rate of spray mixture is adjustable between 0-120 mL/min, and the application rate of spray mixture is only 15-30L/ha. Compared with those of conventional hand-held hydraulic sprayers, 96-98% of spray mixture and 20-50% of a. i. dosage could be cut down respectively. The swath width from left to right could be 3-4 m if nozzle is swinged horizontally over the crop, and the time for treating 1 ha takes 5-10 h. HANDIMIST?has been applied on 12 crops and fruit trees successfully for controlling 21 insect pests and 6 plant diseases and proved valuable for small-scale farmers as a high-efficiency, water and pesticide saving hand-operated spray equipment.

根据双流体雾化原理设计了一种新型的手动吹雾器,在0.03MPa的空气压力下,通过特制的气力式环孔形喷头可把水质喷雾液分散成容积中径VMD值为50~100μm的细雾,雾流夹角为25°~30°的窄幅实心雾锥。药液流速0~120mL/min可调。每亩田的喷雾量只需1~2L。与传统的液力式手动喷雾器相比,喷雾量可降低96~98%,农药用量可减少20~50%。采取左右摆动的扫描式喷撒法时,喷幅可达3~4m,处理一亩田的时间为20~40分钟。已成功地在12种作物上对21种主要虫害和6种主要病害进行了多年试验示范,是一种适合于小规模农业生产体制的高效、节水、节药喷雾器械。

In this paper, three typies of fuel nozzle differet in atomization principle are separately tested on a jet engine combustion apparatus to examine their performance. These nozzles are characterized by pressure-swirl,airblast and air-assist pressure-swirl. Experiments show that changing in combustor inlet air velocity can slightly improve exit temperature profile, when whichever nozzle is used, pressure-swirl atomizer has the features of good ignition and flame stabilization, but lower combustion efficiency...

In this paper, three typies of fuel nozzle differet in atomization principle are separately tested on a jet engine combustion apparatus to examine their performance. These nozzles are characterized by pressure-swirl,airblast and air-assist pressure-swirl. Experiments show that changing in combustor inlet air velocity can slightly improve exit temperature profile, when whichever nozzle is used, pressure-swirl atomizer has the features of good ignition and flame stabilization, but lower combustion efficiency and higher exit extreme temperature.Compared with pressure-swirl atomizer, airblast atomizer is of higher combustion efficiency, better ignition at high air velocity and poorer at low air velocity, and poorly lean fuel-extinction limit; Air-assist pressure-swirl atomizer is of higher combustion effeciency, better ignition and flame stabilization, and with easy to control the position of exit extreme temperature.

在WP-7发动机单管燃烧室上采用三种不同形式的燃油喷嘴(离心式、空气雾化式及气旋离心式)进行燃烧试验以研究燃油喷嘴对燃烧性能的控制作用.实验显示了不同形式的喷嘴产生出燃烧性能的差别.通过考察该三种喷嘴对出口温度场燃烧效率、温度不均匀系数、点火、火焰稳定等的控制程度得出:根据需要,可以选择适当的喷嘴来控制性能.特别是本文研究的气旋离心式喷嘴易于控制出口温度场的热点位置,具有离心式和空气雾化式两种喷嘴的优点.
