結構特點
與WFB型自吸泵相比，WLZ（WZY）型自吸泵具有明顯技術優(yōu)勢：
1、水泵葉輪為閉式結構，效率較WFB泵葉輪采用的開式結構高10％～15％，同性能參數(shù)泵所配電機功率普遍低一個檔次，節(jié)能顯著，同時，葉輪汽蝕性能好，安裝允許吸深較WFB泵深0.5～1m。
2、水泵自吸采用“多通道葉片式氣水混合分離器（自吸盤）”，具有快速完成自吸過程的突出特點，較WFB型泵采用單蝸殼式壓水室自吸時間縮短1/3～1/2以上，而且泵體積小，重量輕。
3、進水型式有兩種：WLZ型泵采用管道式結構，進、出口可在平面360°任何方位吸入排出。WZY型泵采用下吸式，排出口可在平面270°任何方向。檢修水泵時，均無需拆卸進、出口管道，特別是WZY型占地面積小，節(jié)省基建投資。
4、密封采用多面連環(huán)流體動力密封，由副葉輪密封和停機密封組成，WFB型流體動力密封未設專用停機密封，不適用于頻繁啟動場合。
5、聯(lián)接方式為水泵和電機剛性直聯(lián)。從電機端俯視，泵為順時針方向旋轉。
6、水泵進口無需像WFB泵那樣帶止回閥或電磁真空破壞閥等輔助設備，本身具有自動破壞虹吸的U型管特殊結構和空氣平衡孔，停機時，虹吸作用不能抽空泵內儲液，因此，只要首次運行時注滿液體，以后運行無需加液，真正實現(xiàn)一次注液，終身受用。
7、水泵可配備控制柜，它具有根據(jù)液體自動啟停和過載報警等多種功能，實現(xiàn)無人操作，自動工作。

Type WLZ、WZY Vertical Non-Leakage Self-suction Pump
General
Type WLZ、WZY pump which designed and developed by our factory is our country’s pioneering product (Patent No. 200320114083.4). It is widely used in the fields of petroleum, chemical, metallurgy, power station, steel, mine, paper-making, electrodeposit, environmental protection, fire-extinguishing, architecture and sewage-treating. Part of them can instead of inundated pump, long-shaft pump or pump started frequently. It is suitable for delivering clear water, seawater, sewage with little particles (no fibre), industrial waste water, oil and other medium with corrosion.

Construction feature
Type WLZ (WZY) self-suction pump has more advantages than type WFB self-suction pump. The feature is as following:
1. The impeller is closed structure with excellent performance. Its efficiency is 10%～15% higher and permissible installing suction depth is 0.5～1m deeper than that of type WFB pump with opened impeller. Compared with other pumps with the same performance parameter, the motor power of this kind pump can be more low, so it saves more energy.
2. Pump adopts air-water mixed vane segregator with many passages (self-suction disc) for suction, the suction speed is more fast and its self-suction time is 1/3～1/2 shorter than that of type WFB pump with single volute pressure water chamber. The pump has small cubage and light weight.
3. There are two types for water entering：Type WLZ pump adopts pipe-structure with inlet and outlet installed at any angle of plane 360°. Type WZY pump’s suction mouth is downward and outlet can be installed at any angle of plane 270°.It has the features of space-saving and less cost for construction. It needn’t dismantle inlet and outlet pipes while maintenance.
4. Seal uses dynamical sealing which includes vice-impeller sealing and breakdown sealing. But type WFB pump has no special breakdown sealing and it is not suitable for start-up frequently.
5. Connection: Pump is connected with motor through rigid coupling. View from motor end , the rotating direction of pump is clockwise.
6.It is unnecessary to fix check valve or electromagnetism vacuum-destroy valve in pump inlet, it has U pipe which can automatically break siphon and air-balance hole, when pump stops operating, siphon can not pump all water out of pump , so only when pump first starts, it should be poured liquid.
7. Pump Can be equipped with controller which can automatically start and stop pump according to liquid level, and give an alarm for over loading, pump can work automatically without any help of people.
