MFY型磁力驅(qū)動液氯液下泵
　　MFYMagnetic Driven Submerged Liquid Chlorine Pump

　　MFY型泵是一種液下式磁力驅(qū)動筒袋泵，廣泛應(yīng)用于氯堿行業(yè)對液氯的加壓輸送、包裝及處理。采用雙層隔離套保護(hù)，不需要氮?dú)飧綦x密封，無氮?dú)夂吐葰鈸p耗，不會產(chǎn)生混合尾氣，內(nèi)部可實(shí)現(xiàn)自動排氣，彌補(bǔ)了普通液氯液下泵在生產(chǎn)中存在的安全隱患，滿足液氯連續(xù)、高壓輸送和灌裝的需要。
　　MFY is a submerged magnetic driven barrel pump, extensively used in pressurizing, conveying, packaging and disposing of liquid chlorine in chlor-alkali industry. Double-layer spacer sleeve protection is adopted, without the need of nitrogen isolation and sealing, no nitrogen and chlorine loss, and it produces no mixed tail gas; automatic vent can be realized within the pump, avoiding the safety hidden perils in the production with ordinary submerged pump for liquid chlorine, and fully meeting the needs in continuous conveying and filling of liquid chlorine under high pressure.

　　結(jié)構(gòu)說明Description of structure

　　1.液下式磁力驅(qū)動多級離心泵，軸向吸入、徑向剖分。
　　1.A multi-stage magnetic driven submerged centrifugal pump, with axial suction and radial splitting.

　　2.立式筒袋式雙層殼體結(jié)構(gòu)，內(nèi)層為節(jié)段式，泵的外殼承受入口壓力，外殼的長度以及泵的插入深度取決于裝置汽蝕余量要求，也可以直接安裝在儲存介質(zhì)的容器上，此時不需要安裝外殼，容器即成為泵的外殼。
　　2.It is in vertical barrel double-volute structure, the inner layer is sectional, and the outer shell withstands the suction pressure, its length and pump insertion depth depend on the NPSH requirement of the unit, it can also be directly mounted on the vessel storing the media, in this case, outer shell is not required, and the vessel can serve as the outer shell of the pump.

　　3.特殊的首級葉輪設(shè)計(jì)技術(shù)，優(yōu)秀的誘導(dǎo)輪技術(shù)，低轉(zhuǎn)速、低汽蝕余量、高抗汽蝕性能。
　　3.Special first-stage impeller design technique and excellent inducing wheel technique, low speed, low NPSH and high resistance to cavitation.

　　4.軸向力利用流體力學(xué)的平衡鼓技術(shù)自動平衡，充分保證了泵的正常啟停和滑動軸承的使用壽命。
　　4.The axial force is automatically balanced with the balance drum technology in hydrodynamics, fully ensuring the normal start and stop of the pump and the service life of sliding bearings.

　　5.通過磁性聯(lián)軸器驅(qū)動，所有密封點(diǎn)均由密封墊實(shí)現(xiàn)靜密封，無須干氣作為密封阻隔氣，沒有氮?dú)夂吐葰鈸p耗，不必安裝卸壓管及安全閥，不必配用氮?dú)庵虚g罐及相應(yīng)管路，做到無泄漏。
　　5.It is driven via magnetic coupling, static sealing is realized with sealing packs at all points, no need for dry gas as sealing gas, therefore there is no nitrogen or chlorine loss, and it is not necessary to provide pressure relief pump and relief valve, or intermediate nitrogen tank and associated piping, completely avoiding leakage.

　　6.隔離套材料選用高強(qiáng)度、高阻抗的材料，在旋轉(zhuǎn)磁場中極大的降低了磁渦流的產(chǎn)生，磁渦流損失小，磁傳動效率高，對介質(zhì)的溫升影響小。
　　6.Spacer is made of materials with high strength and high impedance, greatly reducing the magnetic vortex in the rotating magnetic field, therefore low magnetic vortex loss, high magnetic driving efficiency and small impact to the temperature rise of media.

　　7.采用雙層隔離套結(jié)構(gòu)，雙重靜密封，實(shí)現(xiàn)雙重保護(hù)，并配置液體泄漏檢測儀表，可實(shí)現(xiàn)泄漏報(bào)警，更加安全可靠。
　　7. Double layer spacer structure is used with dual static sealing, realizing dual protection, and liquid leakage detection instrument is provided, to realize leakage alarm, for increased safety and reliability.

　　8. 的泵的內(nèi)部循環(huán)系統(tǒng)和泵與儲罐之間的氣相平衡系統(tǒng)，讓整個泵組件在邊界條件下都是安全的。
　　8. Unique internal circulating system of the pump and the gas-phase balance system between the pump and tank, so that the whole pump is safe under boundary conditions.

　　9.一般安裝于系統(tǒng)的位，當(dāng)需要排除液氯時也比較方便和迅速。
　　9.Normally it is installed at the lowest position of the system, and when it is necessary to remove liquid chlorine, it can be done conveniently and quickly.
