石油管涂漆以往完全靠手工操作,劳动强度大、效率低,对工人键康有一定影响,油漆浪费。上钢一厂为改变这种落后状况,满足油井管日益增长的需求。自行设计制造了一套油管自动高压静电喷漆流水线。自82年底上机运行以来,情况一直正常。效果明显,可节约劳动力50%以上,油漆消耗节约40%、年节电1800万度。本流水线采用50—70℃蒸汽烘干,可连续静电喷涂,钢管前进速度8～25米/分连续可调,提升机构上升速度17.3米/分能断续或自动上升,设备能力33230吨/年。使用醇酸树脂配成1~#漆,油漆粘度13—15秒/20℃,油漆电阻率20—50MΩ/cm~2,喷涂速度2790转/分二支喷枪,输漆量20—180毫升/
In the past, petroleum pipe painting was entirely operated by hand, with great labor intensity and low efficiency, which had a certain impact on workers’ health and paint waste. A steel plant to change this backward conditions, to meet the growing demand for oil well pipe. Design and manufacture of a set of tubing automatic high-pressure electrostatic painting lines. The situation has been normal since the aircraft was put into operation at the end of 82. The effect is obvious, can save labor more than 50%, paint consumption savings of 40%, saving 18 million degrees. The line uses 50-70 ℃ steam drying, continuous electrostatic spraying, steel tube forward speed of 8 ~ 25 m / min continuously adjustable, lifting mechanism to rise 17.3 m / min to intermittent or automatic rise, equipment capacity of 33230 tons / year . Use alkyd resin dubbed 1 ~ # paint, paint viscosity 13-15 seconds / 20 ℃, paint resistivity 20-50MΩ / cm ~ 2, spraying speed 2790 rev / min two spray gun, the amount of paint 20-180 ml /
