四川省荣县水泵厂和重庆大学研制成功的PI—1型喷浆机(见图),由水泵、电动机、储浆桶和喷枪等部件组成。结构上采用单吸单级直联式离心泵作喷浆动力,使结构紧凑,减少管路,便于移动和操作。并设置安装有回流搅拌新结构,工作时有一股回流倒入储浆桶,起搅拌防沉淀作用,确保了浆液 The PI-1 sprayer developed by the Rongxian Pumping Plant in Sichuan Province and Chongqing University (see figure) consists of pumps, motors, storage tanks, and spray guns. Single-suction, single-stage, direct-coupled centrifugal pumps are used for spraying power in the structure, which makes the structure compact, reduces pipelines, and is easy to move and operate. And set up a new structure with reflux mixing. When working, there is a backflow into the slurry tank, which acts as a stirring and anti-precipitation to ensure the slurry.
