撓性泵(bèng)與離心(xīn)泵(bèng)的比較

離心泵由于(yú)結構簡單、效率(lǜ)高、流量大、無脈(mò)動、價格低而廣(guǎng)泛使用，離(lí)心泵約占全(quán)部工、農業用泵(bèng)量的百(bǎi)分之(zhī)八(bā)十以上(shàng)。共同的特點(diǎn)：結構簡(jiǎn)單液(yè)流平穩無脈動中小(xiǎo)流量領域(yù)有相(xiàng)似(sì)的效率和運(yùn)行曲線。撓(náo)性泵(bèng)的優(yōu)勢：離心泵(bèng)隻能用于(yú)稀薄、低粘(zhān)度的液體(tǐ)，無法輸送中、高粘度的流(liú)體、半(bàn)流體(tǐ)。而撓性泵從低到(dào)高粘度(dù)均可(kě)。離心泵無(wú)法輸(shū)送含較大(dà)懸浮顆粒的介質。離心泵(bèng)無法(fǎ)輸送含(hán)氣液、泡(pào)沫液(yè)。離心泵轉(zhuǎn)速高，不能低轉(zhuǎn)速運行，所以對(duì)介質剪(jiǎn)切極大，不适合輸送對(duì)剪切具(jù)有(yǒu)敏感的介質。離心泵(bèng)無自吸能力。如(rú)要自吸(xī)需(xū)加附(fù)加裝(zhuāng)置(zhì)，如(rú)儲液罐、底(dǐ)閥，次啓動需灌液(yè)，完成自(zì)吸動(dòng)作的速度(dù)慢；應用于(yú)衛生領域(yù)，儲(chǔ)液罐有可能成爲新的污染(rǎn)源。此外，離(lí)心泵的安(ān)裝(zhuāng)位(wèi)置受(shòu)限。後(hòu)，請注(zhù)意，離心泵不能(néng)作爲(wèi)計量泵使(shǐ)用。一般來(lái)講，撓(náo)性泵與離心(xīn)泵(bèng)之間無競(jìng)争關系。撓性(xìng)泵作爲離心泵的替代泵種，主要用于(yú)吸排離(lí)心泵無(wú)法輸送(sòng)的介質或離心(xīn)泵(bèng) 無法(fǎ)适應的(de)工況場(chǎng)合(圖\文 xiaojikuaipao.top/news.asp )。
中(zhōng)譯英(yīng)：
centrifugal pump with the advantages of simple structure, high efficiency, large flow, no pulse, low prices and widespread use of centrifugal pump, accounted for about all workers, more than eighty percent of the volume of agricultural pumps. common features: simple structure smooth flow pulsation free medium and small flow field have similar efficiency and operation curve. advantages: flexible pump centrifugal pump can only be used to thin, low viscosity of the liquid, to transportation, high viscosity fluid, semi-fluid. the flexible pump from low to high viscosity can be. centrifugal pump with large transport of suspended particles in the medium. centrifugal pump to transfer with gas liquid, foam liquid. centrifugal pump with high speed, low speed operation can not, so the medium shear greatly, not suitable for the transport of shear sensitive media. centrifugal pump self-suction capability. if the self-priming need to add additional device, such as a liquid storage tank, valve, first start need irrigation fluid, completion of self-sucking action speed is slow; used in the health field, liquid storage tank has the potential to become the new source of pollution. in addition, centrifugal pump installation position is limited. finally, note, centrifugal pump can not be used as a metering pump use. generally speaking, the flexible pump and centrifugal pump without competitive relationship between. flexible pump centrifugal pump pump as alternative, mainly used for suction centrifugal pump can transport medium or centrifugal pump can not adapt to situations.
