FMZ型氟塑料磁力驱动自吸泵 

   Fluoroplastic Magnetic Driven Self-priming Pump

   FMZ型氟塑料磁力驱动自吸泵，是按照水力学原理结合非金属泵的工艺特点设计制造的，该泵适宜于槽车、船舶装卸及各种化工流程中有自吸要求的场合，主要用于输送强酸、强碱、有毒、有害及纯净贵重的腐蚀性化学介质，确保自动排出进口管路中的空气迅速引液和满足流动岗位自吸抽送的要求。

   Model FMZ fluoroplastic magnetic driven self-priming pump is designed and made to hydraulic principle in conjunction with the process features of non-metal pumps; it is suitable in applications for tanker and vessel loading and unloading and various chemical processes requiring self-priming, mainly used to convey strong acid, strong alkali, toxic, harmful and pure valuable and corrosive chemical media. It can ensure quick priming by automatically venting air in the suction piping and meet the requirement of self-priming and pumping at mobile locations.

    1.该泵主要由储液室、涡室、回流孔、叶轮、泵盖组成，储液室在开机前注满液体，在叶轮的高速运转下将气液混合物带进涡室加压后进入气液分离室，在气液分离室内空气自然进入管网，液体则自动从回流孔回流，与储液室内的空气再次混合，循环往复，直至吸入管路中的空气被排尽。

   This pump mainly consists of the fluid reservoir, volute chamber, reflowing valve, impeller and cover; the fluid reservoir is full of liquid before startup, with the high speed rotation of impeller, and the air and liquid mixture is carried into the volute chamber and pressurized before entering the air and liquid separation chamber, where air flows naturally into pipe and liquid flows back automatically via the reflowing valve, to mix with the air in the reservoir again. This process is repeated until all air in the suction piping is removed.

    2.该型泵为卧式、外混式自吸泵、磁力驱动全密封、无泄漏。

    This pump is of horizontal external mixing self-priming type, magnetic driven, totally enclosed, and free of leakage.

    3.泵体采用金属外壳内衬氟塑料，过流部件全部采用氟塑料合金制造，泵盖、叶轮等均用金属嵌件外包氟塑料整体压制而成。

    The metal pump casing is lined with fluoroplastics; all flow passage parts are made with fluoroplastic alloy, and pump cover and impeller are made by integral pressing of metal wrapped with fluoroplastics.
    4.泵轴由高强度的无压烧结碳化硅制成，滑动轴承由高密度碳型碳化硅材料制成。

    The pump shaft is made with high strength pressureless sintered carborundum, and sliding bearings are made with high density carbon type carborundum.

    5.整台泵只需要1-2个密封圈，确保了安全性。

    The whole pump requires only 1~2 sealing rings, ensuring best operation safety.

    6.选用纤维增强罩保护的隔离套，既消除了涡流损失，又获得了足够的强度，提高了隔离套的承压能力。

    Spacers protected by fiber-reinforced hood are used, eliminating eddy current loss and obtaining sufficient strength, with increased pressure bearing capacity of spacer.

    7.不需要安装底阀，在吸程范围内，可替代液下泵。

    No bottom valve is required, and it can be used in place of submerged pump within the range of suction head.
