1、防爆电加热器不得随意的拆卸；拆卸检修时，不能用零件的防爆面作为撬棒的支点，更不允许敲打或者撞击防爆面。

1, explosion-proof electric heater shall not be arbitrarily; Remove the maintenance, can't use parts of the explosion-proof surface as a lever fulcrum, more is not allowed to knock or hit the explosion-proof surface.

2、拆卸电加热器时，应先取下风罩、风扇，再使用套管板手拆卸端盖和轴承盖的螺栓，然后，使用圆木或铜棒沿轴向撞击轴伸，使端盖和机座分开，最后取下转子。拆除零件，防爆面应朝上面搁置，并用橡皮或者布衬垫盖上，紧固螺栓，弹簧垫等等注意不要丢失。

2, removing electric heater, should first take cover lee, fan, using the sleeve wrench remove end cover and the bearing cap bolts, then, use log or copper bar along the axial impact shaft extension, the end cover and stand apart, and finally remove the rotor. Dismantled parts, explosion-proof surface should be toward the top, with a rubber cover pad or cloth, tighten bolt, spring cushion, etc. Be careful not to lose.

3、浸漆和组装时，应将防爆面附着的绝缘漆或者脏物清洗干净，不得用铁片等硬物刮划，但可以用油石研磨不平整的地方。

3, dip coating and assembly, explosion-proof surface adhesion of insulation varnish or dirt should be cleaned, may not be scratching with iron and other hard objects, but can use abrasive grinding uneven places.

4、若防爆面损伤，必须用铅锡焊料 HISnPb58-2 ，焊剂为 30% 浓度的盐酸（对钢制零件）或含锡58~60% 的锡锌焊料，焊剂为氯化铵 30% ，氯化锌 70% ，加水 100~150% 混合溶液（对铸铁件）进行焊补，焊料与零件的结合要牢固，凸起部分要磨平，达到规定的光洁度。

4, if the explosion-proof surface damage, tin-lead solder must use HISnPb58-2, flux of 30% concentration of hydrochloric acid (for steel parts) or contain zinc tin 58 to 60% of the tin solder, flux is 30% ammonium chloride, zinc chloride 70%, add water 100-150% mixture (iron) for weld repairs, the combination of solder and parts wants firm, raised portion to smooth, meet the finish.

5、为防止防爆面生锈，应在防爆面上涂抹机油或 204-1 置换型防锈油。

5, to prevent rust, explosion-proof surface should apply the oil on the surface of the explosion-proof or replacement type rust-proof oil 204-1.
