  MFY型雙殼體液氯磁力泵是一種液下式磁力驅(qū)動(dòng)筒袋泵，廣泛應(yīng)用于氯堿行業(yè)對(duì)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(huì)產(chǎn)生混合尾氣，內(nèi)部可實(shí)現(xiàn)自動(dòng)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
液下式磁力驅(qū)動(dòng)多級(jí)離心泵，軸向吸入、徑向剖分。
A multi-stage magnetic driven submerged centrifugal pump, with axial suction and radial splitting.

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，外殼按壓力容器設(shè)計(jì)，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(chǔ)存介質(zhì)的容器上，此時(shí)不需要安裝外殼，容器即成為泵的外殼。
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.

特殊的首級(jí)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、高抗汽蝕性能泵的氣蝕余量NPSHr=0.5-0.8m。
Special first-stage impeller design technique and excellent inducing wheel technique, low speed, low NPSH and high resistance to cavitation.

軸向力利用流體力學(xué)的平衡鼓技術(shù)自動(dòng)平衡，充分保證了泵的正常啟停和滑動(dòng)軸承的使用壽命。
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.
通過磁性聯(lián)軸器驅(qū)動(dòng)，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。
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.

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(dòng)效率高，對(duì)介質(zhì)的溫升影響小。
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.

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(cè)儀表，可實(shí)現(xiàn)泄漏報(bào)警，更加安全可靠。
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.

的泵的內(nèi)部循環(huán)系統(tǒng)和泵與儲(chǔ)罐之間的氣相平衡系統(tǒng)，讓整個(gè)泵組件在邊界條件下都是安全的。
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.

一般安裝于系統(tǒng)的位，當(dāng)需要排除液氯時(shí)也比較方便和迅速，防止了液氯中NCL3聚集的安全風(fēng)險(xiǎn)。
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.

泵的內(nèi)置滑動(dòng)軸承選用高純度的碳化硅陶瓷復(fù)合材料，具有較高的強(qiáng)度、韌性及耐磨性和良好的自潤滑性能，可適應(yīng)液氯在氣液混合態(tài)下近似于干運(yùn)轉(zhuǎn)的工況。
The built-in sliding bearings in the pump are made of high-purity silicon carbide ceramics composite material, featuring high strength, tenacity, wearing resistance and good self-lubrication performance, able to meet the nearly dry operation condition for liquid chlorine in the mixed status of gas and liquid.

泵的入口尺寸采用加大設(shè)計(jì)，均在DN100以上，以降低泵與液氯儲(chǔ)罐之間接管的阻力損失。
配置變頻調(diào)速電機(jī)對(duì)泵的流量及出口壓力進(jìn)行調(diào)節(jié)，以給定的壓力為基點(diǎn)進(jìn)行調(diào)整，壓力波動(dòng)小，控制可靠穩(wěn)定。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。
