離心(xīn)泵
約占全部工(gōng)、農業用泵(bèng)量的百分(fèn)之(zhī)八十以(yǐ)上。共同(tóng)的特點(diǎn):結構簡單(dān)液流(liú)平穩無脈動中小流量領域有相似(sì)的(de)效率和運行(háng)曲線。撓性泵的優(yōu)勢(shì):離心(xīn)泵隻能用于(yú)稀(xī)薄、低粘度(dù)的液體,無法(fǎ)輸(shū)送中、高粘度的流體(tǐ)、半流體(tǐ)。而(ér)撓性泵從(cóng)低(dī)到(dào)高粘(zhān)度均可。離(lí)心泵(bèng)無法輸送(sòng)含較(jiào)大懸(xuán)浮顆粒的(de)介(jiè)質(zhì)。離心泵無(wú)法輸送含氣(qì)液(yè)、泡沫液。離(lí)心泵(bèng)轉速高,不能低(dī)轉速(sù)運行,所以(yǐ)對介質剪(jiǎn)切極大,不适合輸送對剪切具(jù)有敏感的介(jiè)質。離心(xīn)泵無自吸能力(lì)。如(rú)要自吸(xī)需加(jiā)附加裝置,如儲液罐、底閥,次啓(qǐ)動需灌液,完成自吸(xī)動作的速(sù)度慢;應用(yòng)于衛生領(lǐng)域,儲液罐(guàn)有可能成爲新(xīn)的污染(rǎn)源。此外(wài),離心泵的(de)安裝位(wèi)置受限。後,請(qǐng)注意,離心(xīn)泵不能作爲計(jì)量泵(bèng)使用。一般(bān)來講,撓性(xìng)泵(bèng)與(yǔ)離心(xīn)泵之間(jiān)無競争(zhēng)關系。撓(náo)性(xìng)泵(bèng)作爲離心泵的替(tì)代泵(bèng)種,主要用于吸(xī)排離(lí)心泵無法輸送的介(jiè)質或

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.
