大桥工程局一处三队近三年来研制革新一种长杆喷漆枪(如图)。它由喷头、管杆、转向架、手柄开关等部分组成。以风压推动活塞顶针来控制涂料和风路,枪头安装有能转360度的转向装置,用上海油漆工具厂生产的PQ-2型喷咀配套。该枪喷出的油雾成扁平形状,雾化均匀,厚薄一致,它与短喷漆枪喷涂、人工 Bridge Engineering Bureau, a team of nearly three years to develop a long pole spray gun (pictured). It consists of nozzle, pipe, bogie, handle switch and other components. Piston thimble with air pressure to control the paint and air duct, the gun head can be installed to turn the steering device 360 ​​degrees, with the Shanghai Paint Tools Factory PQ-2-nozzle matching. The gun sprayed into a flat shape of the oil mist, uniform atomization, the same thickness, it is sprayed with a short spray gun, artificial
