1、的雙吸結構設計，基本消除了軸向力和 徑向力，摒棄了 WFB 泵故障率的入口真空閥。
2、可替代鋼廠旋流井，沖渣池等工況現有的 WFB 無密封自吸泵，節約能耗 40%~60%；
3、替代長軸液下泵在不增加能耗的基礎上可以 延長維修周期，節約維修費用；
4、替代目前帶真空裝置的高效節能自吸泵，帶真空裝置高效自吸泵，操作繁瑣，電氣元件真空裝置容易損壞，機械密封稍微泄漏，無法抽真空，無法工作，故障率。
5、模塊化設計、互換性強、維護方便。
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.
目前鋼鐵行業冶煉過程中，旋流井、沖渣池普遍使用的WFB無密封自吸泵或長軸液下泵，運行效率低（普遍只達到50%）、耗能高、汽蝕嚴重、維修頻繁、零配件不通用；后期市場推廣的，帶真空裝置的高效自吸泵，由于采用機械密封，對于介質中含有大量氧化鐵皮顆粒、油污，機械密封容易磨損，導致泄漏，所配套真空裝置無法上水，危及旋流井安全運行。針對這些老式自吸泵的缺陷，我公司與相關科研院校合作，經過多年研發，終于成功開發出高效無密封自吸泵。
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.
