一、气动喷补机简单介绍在国外,喷补技术已大量推广应用,各科喷补机相继问世。我国喷补技术也已在推广应用,尤其在钢铁行业中,不但应用喷补技术,而且也引进了先进的喷补设备,但目前尚无专业厂生产类似的先进设备。本文介绍的气动喷补机是在吸收国外先进喷补机优点的基础上,结合国内实际情况设计制造的,它具有结构简单、使用方便、造价低等特点,它的工作原理是利用压缩空气将喷补材料与水按一定比例混合后喷射到所需修补部位,详见气动喷补机原理图。基本参数如下: a、喷补量:60～120kg/min b、喷补材料比重:2 t/m~2 粒径:<5 mm c、压缩空气压力:0.5～0.7MPa 流量:7.5m~3/min First, a brief introduction to pneumatic gunner In foreign countries, a large number of spray gunning technology has been widely applied, all branches of gunpowder have come out. China’s spray technology has also been popularized, especially in the steel industry, not only the application of gunning technology, but also the introduction of advanced gunning equipment, but there is no professional factory production of similar advanced equipment. This article describes the pneumatic gun is based on the advantages of absorbing foreign advanced gunpowder, combined with the actual situation of the domestic design and manufacture, it has a simple structure, easy to use, low cost, its working principle is the use of compressed air Spray material and water according to a certain percentage of mixed injection to the required repair site, see the pneumatic gun machine schematic. The basic parameters are as follows: a, the amount of spray: 60 ~ 120kg / min b, the proportion of shotcrete material: 2t / m ~ 2 particle size: <5mm c, compressed air pressure: 0.5 ~ 0.7MPa Flow: 7.5m ~ 3 / min
