QSH-4型喷涂枪是我所于1977年上半年研制成功的氧乙炔焰粉末喷涂工具。经过多年应用表明,该喷涂枪不仅具有火焰燃烧稳定、不易回火、火焰功率调节的范围广、吸粉力强、送粉量大、粉量调节均匀、枪体轻(1450克)、操作简便、容易维护等特点,而且还可在乙炔气为低压的条件下应用。结构特点及其技术参数 QSH-4型氧乙炔焰粉米喷涂枪外观如图1所示。它主要由火焰燃烧与粉末供给两个系统组成。其火焰燃烧系统根据射吸式原理,
QSH-4-type spray gun is the first half of 1977 I developed oxy-acetylene flame powder spraying tool. After years of application, it shows that the spray gun not only has the advantages of stable flame combustion, easy tempering, wide range of flame power adjustment, strong powder suction capacity, large amount of powder feeding, even powder volume adjustment and light gun body (1450 g) , Easy to maintain and so on, but also in the acetylene gas for low pressure conditions. Structural characteristics and technical parameters QSH-4-type oxyacetylene flame powder spray gun appearance shown in Figure 1. It is mainly composed of two systems of flame combustion and powder supply. Its flame combustion system according to the principle of shooting suction,
