1.进料接管和出风接管焊前对好中心，内孔保证￠204管道能穿过。
2.焊接采用手工电弧焊，焊条牌号J420G。
3.涂装前要进行表面除锈、清除焊接残渣等，其质量等级见JB/T5000.12的规定；涂底漆一层、中黄和中蓝色（按颜色样板）聚氨酯面漆二层。除各盖板涂中黄漆外，其余均涂蓝色。漆中不允许含铅。不允许有漏漆、皱漆等缺陷。
4.盖板如密封不严可用CH107,JLC-1等密封胶涂在缝隙大处。
5.两端板上的六个螺柱安装防尘罩中MRM80.5.1防尘台时焊接。
6.总宽度待买来拉手后确定。

1. before the feeding control and the wind meets the tube welding, to the good center, in the hole guaranteed that ¢204 the pipeline can pass through. the
2. welding uses the manual arc welding, welding rod trademark J420G. before the
3. painting, must carry on the superficial stain removal, the elimination welding residual and so on, its quality scale sees JB/T5000.12 the stipulation; Prime, in Huang He the blue color (according to color model) the polyurethane finishes two. Besides various laps spread the yellow paint, other spread the blue color. In the paint does not allow to contain the lead. Does not allow to have leaks flaws and so on paint, wrinkle paint.
4. sealants and so on lap like seal lax available CH107, JLC-1 spread in the slit main point. on
5.2 terminal plate's six studs install in the dust cover when the MRM80.5.1 dustproof Taiwan welds. after the
6. overall width treats buys shakes hand, determined. 

1. The wind over nozzles and feed for good center hole, can guarantee ￠204 pipeline through.
2 use manual welding arc welding, electric welding J420G grades.
3 before coating surface derusting, etc, the quality of welding residue levels seen JB/T5000.12, A primer ZhongHuang and blue color sample (in) pu top-paint layer. In addition to cover ZhongHuang paint besmear outside, the besmear blue. Don't allow lead-based paint. Don't allow have leakage defects such as paint, lacquer.
4. Cover CH107 available, such as sealing lax JLC - 1 in large aperture sealant.
5 ends on the board and six luozhu installation in Taiwan MRM80.5.1 dustproof when welding.
6 always width to buy after the shake handshandle.
