1.將泵從設備上卸下來，放入真空加熱爐內，緩慢增加溫度至400-450度，升溫過程不得少于兩個小時。要注意溫度的控制，如果過熱，會造成泵體的材料硬度下降，影響尺寸的穩定性。

　　2.完全炭化物料的時間為3-12小時，這取決于物料本身，泵的大小，加熱溫度及爐子的負荷。泵需要自然冷卻至室溫，不得強制冷卻。

　　3.必要時可將泵送回我公司進行徹底修復。

　　1. Remove the pump from the equipment, then put it into vacuum heater, increasing the temperature from 400-450℃ （750-850℉）， the process of rising temperature shouldn’t be less than 2 hours. Give your attention to control temperature, if it is too hot, that will reduce the hardness of pump body and influence the dimension stability.

　　2. The time for complete carbonized materials is 3 to 12 hours that depends on the material itself, the pump size, heating temperature and load of the heaters. Cooling the pump to room temperature naturally, it’s forbidden to cool the pump by force.

　　3. You can return the pump to us for a complete repair when it is necessary.
