WFB系列無(wú)密封自控自吸泵采用無(wú)泄漏V型密封總成，革除了傳統(tǒng)水泵的填料密封、盤根密封、機(jī)械密封，*制服了“跑、冒、滴、漏”，是代替原各種長(zhǎng)軸液下泵、潛水泵、潛污泵等的設(shè)備。 該結(jié)構(gòu)泵缺點(diǎn)：

一、停機(jī)液體沿軸方向往外泄漏，對(duì)于頻繁起動(dòng)設(shè)備的場(chǎng)合不太適合；  二、副葉輪消耗的功率太大、水泵效率低。WFB改進(jìn)型結(jié)構(gòu)為有密封裝置，一是提高水泵效率，二是降低電機(jī)功率，     三、是抑制了自吸泵停機(jī)泄漏現(xiàn)象。 運(yùn)動(dòng)過(guò)程中密封裝置不摩擦、無(wú)磨損，使用壽命較同類產(chǎn)品長(zhǎng)10倍以上。
       移植真空泵原理、自吸性能穩(wěn)定可靠，特別是采用“電動(dòng)空氣控制閥”真正實(shí)現(xiàn)了“一次引流，終身自吸”。 效率高、振動(dòng)小、噪音低、移動(dòng)靈活、拆卸簡(jiǎn)便、易于安裝、不需地腳固定，免去了長(zhǎng)軸液下泵運(yùn)輸，安裝、維修等困難。  自吸泵具有*的自控功能，可與高科技領(lǐng)域和高度自動(dòng)化系列統(tǒng)配套使用。
 

WFB series of self-control self-priming pump without seal leak-free V-shaped seal assembly, get rid of the traditional pump packing seals, packing seals, mechanical seal, compley subdued, "run, run, drip, drain," is to replace the original variety long axis of the pump, submersible pump, submersible sewage pumps ideal equipment. The structure of the pump drawbacks: First, stop the liquid leak out along the axis, the occasion for frequent starting equipment is not suitable; two vice impeller power consumption too, pump efficiency is low. WFB improved structure of a sealing device, necessary to raise the pump efficiency, the second is to reduce the motor power, third is inhibition of the pump stop leakage. Movement in the seal is not friction, no wear, long service life 10 times more than similar products.
Transplant vacuum principle, self-priming, reliable performance, especially the use of "electric air control valve" so that "a drainage, lifelong self-absorption."
High efficiency, small vibration, low noise, and flexible, easy disassembly, easy to install, no need to foot fixed, eliminating the long axis of the submerged pump transportation, installation and maintenance difficulties.
Has excellent self-control function, with high-tech and highly automated systems supporting the use of series.
