1、独特的双吸结构设计，基本消除了轴向力和 径向力，摒弃了 WFB 泵故障率最高的入口真空阀。 

2、可替代钢厂旋流井，冲渣池等工况现有的 WFB 无密封自吸泵，节约能耗 40%~60%； 

3、替代长轴液下泵在不增加能耗的基础上可以 延长维修周期，节约维修费用； 

4、替代目前带真空装置的高效节能自吸泵，带真空装置高效自吸泵，操作繁琐，电气元件真空装置容易损坏，机械密封稍微泄漏，无法抽真空，无法工作，故障率极高。 

5、模块化设计、互换性强、维护方便。

1. The unique double suction structure design basically eliminates the axial force and radial force, and discards the inlet vacuum valve with the highest failure rate of WFB pump.

2. It can replace the existing WFB unsealed self-priming pump in steel works, such as whirling well and slag washing pool, and save energy by 40% ~ 60%;

3. Replacing the long shaft submerged pump can prolong the maintenance period and save the maintenance cost without increasing the energy consumption;

4. It can replace the current high-efficiency energy-saving self-priming pump with vacuum device. The operation of the high-efficiency self-priming pump with vacuum device is cumbersome. The vacuum device of electrical components is easy to be damaged, and the mechanical seal leaks slightly, so it can not be vacuumed and can not work. The failure rate is very high.

5. Modular design, strong interchangeability and convenient maintenance.

      目前钢铁行业冶炼过程中，旋流井、冲渣池普遍使用的WFB无密封自吸泵或长轴液下泵，运行效率低（普遍只达到50%）、耗能高、汽蚀严重、维修频繁、零配件不通用；后期市场推广的，带真空装置的高效自吸泵，由于采用机械密封，对于介质中含有大量氧化铁皮颗粒、油污，机械密封容易磨损，导致泄漏，所配套真空装置无法上水，危及旋流井安全运行。针对这些老式自吸泵的缺陷，我公司与相关科研院校合作，经过多年研发，终于成功开发出高效无密封自吸泵。

        At present, in the smelting process of iron and steel industry, WFB unsealed self-priming pump or long shaft submerged pump widely used in swirl well and slag basin has low operation efficiency (generally only up to 50%), high energy consumption, serious cavitation, frequent maintenance, and non-general spare parts; the high-efficiency self-priming pump with vacuum installation, which is promoted in the later stage, has a large amount of iron oxide scale in the medium due to its mechanical seal Particles, oil, mechanical seal is easy to wear, resulting in leakage, the matching vacuum device can not water, endangering the safe operation of the cyclone well. In view of the defects of these old Self-priming pumps, our company has cooperated with relevant scientific research institutions, and after years of research and development, we have successfully developed an efficient non sealing self-priming pump.
