1、降低电热水锅炉http://www.jnshengxin.cn/密封冲洗水进口的温度，增大密封冲洗液的进出口温差。达到了摩擦副所需要的稳定运行温度，减缓了密封元件的失效。
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、在电热水锅炉密封的动环与其固定座之间增加lmm的铜垫，使之达到与进口密封相同的端面比压。在轴套与轴头之间增加一厚为2mm的铜垫，并外缠四氟密封带，从而避免了轴承箱油封被轴套与轴之间泄漏出的高压水刺漏，以至使轴承烧蚀、轴报废的恶性事故发生。
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、提高电热水锅炉配件质量，对机械密封的表面粗糙度提高要求，并要求密封环在研磨前须在常温条件下放置几天甚至两周，或将密封环放在热处理炉内以消除残余应力后再研磨。
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、应清洁电热水锅炉粘接面，涂抹粘接剂，30分钟以内表面固化。螺钉填补及板材封补法。为了使发动机体经修理后能延长寿命，对于受力不大的部位裂纹，且长度小于50mm时，应采用钻孔攻丝，给螺钉涂密封胶拧紧后，可起封补作用。
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.
