清蜡机锅炉是供油田使用的燃烧柴油的快速蒸汽锅炉,最高工作压力达75公斤力/厘米~2,最高蒸汽温度为325℃。锅炉盘管(如图1)由φ25×3毫米和φ35×3.5毫米10号锅炉钢管制成。生产顺序为:接长管子、压管子头、盘管。盘管的焊缝要能经受高温高压,因此必须确保焊透。过去一直采用手工气焊工艺,劳动强度大,生产效率低,每班平均生产60个接头。为改变落后的生产方式,我厂自制了一台长管二氧化碳气体保护自动焊机组。此机组的功能包括:自
Cleaner boilers are fast steam boilers for the combustion of diesel used in the field with a maximum working pressure of 75 kgf / cm 2 and a maximum steam temperature of 325 ° C. The boiler coil (Figure 1) is made of φ25 × 3 mm and φ35 × 3.5 mm No. 10 boiler tubes. Production order: then a long tube, pressure pipe head, coil. Coils of the weld to withstand high temperature and pressure, it must ensure penetration. In the past, the manual gas welding process has been used, which has the advantages of high labor intensity, low production efficiency and an average of 60 joints per shift. In order to change the backward production methods, our factory made a long tube of carbon dioxide gas protection automatic welding unit. The features of this unit include: Self
