磷肥生产过程中需要输送的介质主要有磷矿浆、磷酸料浆、各种滤液、浓磷酸稀磷酸、浓硫酸、稀硫酸及氟硅酸等，泵极易受介质腐蚀或腐蚀兼冲刷磨损。磷酸料浆泵是磷肥生产过程中各种泵的泛称，是极具代表性的耐强腐蚀和抗磨损泵种。在磷肥工业发展的初期，常用的化工耐腐蚀泵，有的寿命只有一周，因此，国内外泵业的专家在磷酸料浆泵的结构设计、材料试验、密封研究等方面做了大量的研发工作。 在磷酸料浆泵的设计中，首先要解决的是耐腐蚀或腐蚀兼冲刷磨损问题。因此，对结构设计和泵壳与叶轮相互间的匹配应加以特殊考虑。国外磷酸料浆泵所用金属材料，是根据介质状况采用不同的系列。国内制造厂和研究单位也分别对各种材料进行腐蚀性能和抗磨损性能的研究，创造出自己的铁素体不锈钢、双相钢、奥氏体不锈钢等材料系列。国内有不少磷酸料浆泵专业制造厂，同时也有中科院、大学、设计院、研究院等参与科研开发，磷酸料浆泵的国产化问题现已基本解决。 国内目前已经建成的大、中、小型磷复肥生产项目中，大、中型装置约有各种料浆泵30～40台，中、小型装置约有各类料浆泵20～30台，按每台泵平均寿命6个月计，市场空间是比较大的。此外，国内尚有一些大磷肥生产企业刚刚建成或基建尚在进行中，加上一批中、小型磷铵改扩建项目，为国内磷肥用泵提供了广阔的市场空间。

原文：
Phosphate fertilizer production process that need to transport the media are mainly phosphate rock slurry, phosphoric acid slurry, all kinds of filtrate, concentrated phosphoric acid dilute phosphoric acid, concentrated sulfuric acid, sulfuric acid, and fluoride acid, etc., pumps vulnerable to media corrosion and erosion corrosion or wear and tear. Phosphate slurry pump is a phosphate fertilizer production process of various pump pan that is a very strong representation of corrosion and wear-resistant pumps kinds. In the initial development of phosphate fertilizer industry, common chemical corrosion resistant pumps, some life span of only a week, so the experts at home and abroad in the phosphate pump slurry pump structural design, material testing, seal research in the field have done a lot of R & D . In phosphoric acid slurry pump design, we must first solve the problem of corrosion and erosion wear or corrosion problems. Therefore, structural design and pump casing and impeller match each other should be special consideration. Foreign phosphate slurry pump used in metallic materials, is based on a series of different media conditions. Domestic manufacturing facilities and research institutes were also a variety of materials corrosion and wear resistance of the research, to create their own ferritic stainless steel, duplex steel, austenitic stainless steel and other materials series. Nations, there are professional manufacturer phosphate slurry pump, but also have Chinese Academy of Sciences, universities, design institutes, research institutes will take part in research and development, the localization of phosphate slurry pump has been basically solved the problem. China has built a large, medium and small-scale phosphate and compound fertilizer production projects, large and medium-sized unit of about a variety of slurry pump 30 to 40 units, medium and small device about all kinds of slurry pump 20 to 30 units, according to The average life expectancy for each pump for 6 months total, the market space is relatively large. In addition, the domestic fertilizer production enterprises are still some large infrastructure projects recently completed or still in progress, together with a number of small and medium ammonium phosphate renovation and expansion project, for domestic phosphate fertilizer pumps provide a broad market space.
