The invention discloses a box type composite silicon carbide ceramic pump which comprises a pump body and a rear protection plate located on the axial bearing side of an impeller. The impeller is installed on a transmission shaft; the pump body and the rear protection plate are formed by one-time casting of a silicon carbide ceramic composite material in a mold; the impeller is made of the silicon carbide ceramic composite material lined with a metal framework; and the silicon carbide ceramic composite material comprises the following components in parts by mass: 300 to 500 parts of silicon carbide particles, 80 to 120 parts of epoxy resin and 10 to 30 parts of a curing agent. According to the box type composite silicon carbide ceramic pump and the manufacturing method thereof provided by the invention, the silicon carbide ceramic composite material is poured after being vacuumized, and is free of bubbles, uniform in material, few in defect and high in strength; inorganic materials such as silicon carbide are filled with resin, so that the thermal expansion coefficient is low; and the pump body, the protection plate and the impeller are formed through one-time casting, so that the size precision is high, and reprocessing is not needed. Low-temperature pouring is adopted, the cost is low, and no pollutant is discharged in the production process.
本发明公开了一种箱体式复合碳化硅陶瓷泵，其包括泵体和位于叶轮轴向轴承侧的后护板，叶轮安装在传动轴上；泵体和后护板由碳化硅陶瓷复合材料在模具内一次浇注成型，叶轮由内衬金属骨架的碳化硅陶瓷复合材料制成；碳化硅陶瓷复合材料，包括以下质量份数的各成分：碳化硅颗粒300‑500份、环氧树脂80‑120份、固化剂10‑30份。本发明将碳化硅陶瓷复合材料抽真空后浇注，无气泡，材质均匀，缺陷少，强度高；树脂填充碳化硅等无机材料，热膨胀系数低；泵体、护板、叶轮一次浇注成型，尺寸精度高，不需再加工。本发明采用低温浇注，成本低，生产过程无污染物排放。
