3Y—35型烟雾机1986年11月通过部级鉴定。如何降低烟雾机的噪声,减少环境污染,是这个课题的一项重要内容。3Y—35型烟雾机系利用脉冲喷气式发动机燃烧的高温气体之热能和高速气流的动能,使液态油溶性药剂迅速热裂,挥发呈白色烟雾,并被高速气流冲击扩散喷出,随气流移动弥漫和渗透到林间(田间)每个角落,从而达到防治病虫害的目的。烟雾机工作时噪声特别大,不喷烟空机工作时最高达124分贝,喷药液工作时噪声也在110分贝左右。尽管烟雾机工作场所大都在农村山区,或空旷原野,或茂密森林里;但因操作者要将机器背在肩上工作,机器发出的噪声距人的耳朵距离不到1
3Y-35-type smoke machine in November 1986 through ministerial identification. How to reduce the smoke machine noise, reduce environmental pollution, is an important part of this issue. 3Y-35-type smoke machine pulse jet engine combustion of high-temperature gas heat and high-speed airflow kinetic energy, the liquid oil-soluble pharmaceutical rapid thermal cracking, volatile white smoke, and was high-speed impact of the proliferation of jet air flow, with the air movement Diffuse and infiltrated into the forest (field) in every corner, so as to achieve the purpose of pest control. Smoke machine working noise is particularly large, do not smoke when the empty machine working up to 124 decibels, the working fluid spray noise is about 110 decibels. Although the workplaces for smoke machines are mostly in mountainous rural areas, in open fields or in dense forests, the noise emitted by the machine is less than 1 from the human ear because the operator is going to work on his shoulder
