電加熱管封口方法

(1).要求有釬焊法蘭類或速接板類零件時，釬焊件必須牢固可靠；

(1).?Requires a?soldered flanges?or?fast connecting?plate parts,?welding?parts must be?solid and reliable;

(2).用于加熱液體類或是密閉電加熱管，應能承受0.3～1.2MPa壓力。歷時5mm的靜水 壓力試驗無滲漏現象。

(2).將兩端MgＯ粉挖掉3～4mm深度，并清理干凈。特別注意其管內壁及螺紋部分不 得有鎂粉存在；

(2).?Both ends of the?MgO powder and?dig out?the depth of 3 ~ 4mm,?and clean.?Pay special attention to?the?inner wall of the pipe?and?threaded?part does not?have?magnesium?exist;

(3).封口前逐件檢查使其元件耐壓2000Ｖ/1s，無擊穿閃絡，絕緣無窮大；

(3).?Before sealing?examined them one by one?the?elements?withstand voltage 2000V/1s,?no breakdown?of insulation?flashover,?infinite;

(4).入封口膠，應旋轉磁堵壓上，然后上螺母、墊圈；

(4).?The?sealing glue,?should be rotated?magnetic plug?pressure,?then the?nut,washer;

(5).兩次口的電加熱管應按操作規程執行。

(5).?Two?the mouth of the?electric heating?pipe should be?according tooperating procedures.
