奉化机械密封件厂在上海硅酸盐研究所的关怀与支持下,成功地试烧了 Q_y 型潜水泵氮化硅机械密封环。氮化硅是一种新型工程陶瓷,它具有强度高、耐腐蚀、耐高温、耐研磨和极好的抗热震性、电绝缘性等优良性能,在制造工艺中又具有可机械加工和无收缩性等优点。因此,能用于各种工程中需要的尺寸精确的部件,尤其是形状复杂的部件,同样能达到成品率较高的要求。目前,它在泵的机械密封方面,用反应烧结氮化硅做盐酸泵和三氯化铁泵的机械密封环 Fenghua mechanical seal factory in Shanghai Silicate Institute of care and support, the successful test burn Q_y submersible pump silicon nitride mechanical seal ring. Silicon nitride is a new type of engineering ceramics with high strength, corrosion resistance, high temperature resistance, abrasion resistance and excellent thermal shock resistance, electrical insulation and other excellent performance, in the manufacturing process can be machined and without Contractility and other advantages. Therefore, can be used for all kinds of engineering needs of the size of the parts, especially the shape of the complex components, the same can achieve higher yield requirements. At present, it is mechanical seal in the pump, the reaction of sintered silicon nitride pump to do hydrochloric acid and ferric chloride pump mechanical seal ring
