Description

具有潜水泵的射流真空泵
技术领域
[0001] 本发明涉及一种潜水栗,属于径向流动非变容式流体栗技术领域。
背景技术
[0002] 射流真空杲是利用机械、物理、化学或物化的方法,在封闭空间中产生、改善和维 持真空的装置。一般由潜水栗、射流真空栗、泵箱三部分组成,被广泛用于石油、化工、食品、 制药、轻工、环保等行业的减压蒸发、结晶、蒸馈、干燥、脱色、脱臭、真空输送等工艺之中。
[0003] 潜水泵通常包含泵体、电机、叶轮;所述泵体上设置有进水口、出水口;电机启动带 动叶轮转动,带动水从进水口进入,然后从出水口排出,水流通道是通过泵体内部的中空部 分形成的通道。
[0004] 潜水泵是输送液体或使液体增压的机械。它将原动机的机械能或其他外部能量传 送给液体,使液体能量增加,主要用来输送液体包括水、油、酸碱液、乳化液、悬乳液和液态 金属等,也可输送液体、气体混合物以及含悬浮固体物的液体。
[0005] 据申请人了解,在水中含有相当多的泥砂时,潜水栗的使用寿命往往不是取决于 电机质量而是取决于水泵过流零件(如叶轮、泵盖)的耐泥砂磨损能力。
[0006] 针对潜水泵而言,原材料成本及加工成本的综合,是不能不考虑的因素。基于这一 条件,采用低成本,探求提高潜水电泵过流零件抗砂磨损性能的途径,是值得重视的一项课 题。
发明内容
[0007] 本发明要解决的技术问题是,针对现有技术不足,提出一种低成本且耐磨和耐冲 击的耐磨耐冲击射流真空泵。
[0008] 本发明为解决上述技术问题提出的技术方案是:一种耐磨耐冲击射流真空泵,包 括潜水栗、射流器和真空罐,所述潜水泵包括栗体、设于栗体内的电机和叶轮,所述栗体上 设置栗盖,所述栗盖上制有出水管,所述电机输出轴朝下伸出且与叶轮中心轴固连,所述射 流器的射流液体进口端连通所述潜水栗的出水口,所述射流器的进气口端连通真空罐出 口,所述泵盖上的出水管包括圆管形的金属基板和陶瓷体,所述金属基板制有贯通其外圆 柱面和内圆柱面的安装孔,所述金属基板外圆柱面和内圆柱面上均覆有浇铸层,所述陶瓷 体设于浇铸层和安装孔内,所述陶瓷体位于所述金属基板外圆柱面的一端制为蜂窝状。
[0009] 本发明采用上述技术方案的有益效果是:1)由于栗盖上的出水管包括圆管形的金 属基板和陶瓷体,通过金属基板制有贯通其外圆柱面和内圆柱面的安装孔,制作出水管时, 可以将陶瓷体设于安装孔上,出水管外部的浇铸层通过安装孔流入出水管内部,将陶瓷体 牢固固定在圆管形的出水管上,使得出水管内部耐磨,成本低;2)由于陶瓷体位于金属基板 外圆柱面的一端制为蜂窝状,使得出水管耐冲击。
[0010]上述技术方案的改进是:所述浇铸层上涂有树脂层。
[0011]上述技术方案的改进是:所述浇铸层含有的成分和质量百分比含量为:C: 3.5〜 3 • 7%,Sb: 0 • 04〜0 • 08%,Mn: 0 • 40〜〇. 60%,Cu: 0.30〜0.40%,其余为Fe和不可避免的夹杂元 素。
[0012]锑:Sb熔点630°C,它是促进珠光体形成元素,对薄壁铸件,可使组织完全珠光 体化,且对不同壁厚基体组织差异极微,壁厚敏感性明显减少。具有较大熔化潜热,加入 0.04〜0.08%含量的Sb,明显细化宏观组织,在部分微区形成温度起伏,引起析出石墨核 心,可细化石墨。
[0013]本发明采用上述技术方案的有益效果是:通过在浇铸层内加入微量的sb和Cu,生 产成本低廉,耐磨性能好,使得潜水泵在水中工作使用寿命提高明显。
[0014]上述技术方案的改进是:所述安装孔是锥形安装孔,所述陶瓷体是对应所述安装 孔的锥形陶瓷体。
