1、降低電熱水鍋爐http://www.shijilu.cn/密封沖洗水進口的溫度，增大密封沖洗液的進出口溫差。達到了摩擦副所需要的穩定運行溫度，減緩了密封元件的失效。
Reduce electric water boiler seal flush water inlet temperature, increasing the temperature difference between the import and export of seal fluid. Reached a stable friction required operating temperature, slowing the failure of the sealing element.

2、在電熱水鍋爐密封的動環與其固定座之間增加lmm的銅墊，使之達到與進口密封相同的端面比壓。在軸套與軸頭之間增加一厚為2mm的銅墊，并外纏四氟密封帶，從而避免了軸承箱油封被軸套與軸之間泄漏出的高壓水刺漏，以至使軸承燒蝕、軸報廢的惡性事故發生。
Between the electric water boiler sealing ring lmm increase its copper pad holder, so as to achieve the same with imports of seal face pressure. Between the sleeve and the spindle head to increase a thickness of 2mm copper pad and outer wrapping PTFE sealing tape, thus avoiding the bearing housing seals are leaking out between the sleeve and the shaft spunlace high pressure leakage, as well as the bearing burn eclipse, accidents happen axis scrapped.
　　
3、提高電熱水鍋爐配件質量，對機械密封的表面粗糙度提高要求，并要求密封環在研磨前須在常溫條件下放置幾天甚至兩周，或將密封環放在熱處理爐內以消除殘余應力后再研磨。
After improving the quality of electric water boiler accessories, mechanical seal surface roughness increase demands and requirements of the sealing ring must be placed in a few days or even weeks at room temperature before grinding conditions, or the seal ring on the heat treatment furnace to remove the residual stress regrinding.

4、應清潔電熱水鍋爐粘接面，涂抹粘接劑，30分鐘以內表面固化。螺釘填補及板材封補法。為了使發動機體經修理后能延長壽命，對于受力不大的部位裂紋，且長度小于50mm時，應采用鉆孔攻絲，給螺釘涂密封膠擰緊后，可起封補作用。
Electric water boilers should be cleaned bonding surface, applying an adhesive surface cure within 30 minutes. Screws and plates filled with compensation method. In order to make the engine block after repair can prolong life for a large part of the crack discontinuity, and the length is less than 50mm, should adopt drilling tapping screws to tighten the sealant after coating, can play a complementary role in sealing.
