不鏽鋼離(lí)心(xīn)泵是廣泛應(yīng)用于化工(gōng)工(gōng)業系統的一(yī)種通(tōng)用流體機械。 不(bú)鏽鋼(gāng)離心(xīn)泵 具(jù)有性能适(shì)應範(fàn)圍廣、體積小、結(jié)構簡(jiǎn)單、操(cāo)作容(róng)易、操作(zuò)費用低等諸多優(yōu)點。通(tōng)常，所(suǒ)選離心泵(bèng)的流(liú)量、壓頭可(kě)能會(huì)和(hé)管路中(zhōng)要求的不(bú)一緻，或由于(yú)生産任(rèn)務、工藝要求發生變(biàn)化，此時(shí)都(dōu)要求(qiú)對泵(bèng)進行流量調節，實質(zhì)是改變離(lí)心泵的工(gōng)作(zuò)點。離心(xīn)泵的(de)工作點是(shì)由泵的(de)特性曲(qǔ)線和管路(lù)系統特性曲(qǔ)線(xiàn)共同(tóng)決(jué)定的，因此，改(gǎi)變任(rèn)何(hé)一個的(de)特性曲(qǔ)線(xiàn)都可以達(dá)到(dào)流量調(diào)節的目的。目前，離心泵的流量(liàng)調節(jiē)方式主(zhǔ)要(yào)有調節閥控制(zhì)、變速(sù)控制以及泵的(de)并、串聯調(diào)節等。由于各種(zhǒng)調節方式的(de)原理不(bú)同，除有自(zì)己的優缺點外，造成的(de)能量損耗也不一樣，爲(wèi)了尋求(qiú)佳、能耗(hào)小、節能的流量調節方(fāng)式，必須全面(miàn)地了解 不鏽鋼離心(xīn)泵 的(de)流量(liàng)調節方式(shì)與能耗之間的(de)關系(xì)(圖\文 xiaojikuaipao.top/ )。

stainless steel centrifugal pump is widely used in the chemical industry system one kind of fluid machinery. stainless steel centrifugal pump has to adapt to a wide range of performance, small volume, simple structure, easy operation, low operation cost etc.. usually, the centrifugal pump flow, pressure head may be in the pipeline and the inconsistent, or because the production task, process requirements change, this time is required to pump flow regulation, essence is to change the operating point of centrifugal pump. centrifugal pump working point is determined by the characteristic curve of pump and system characteristic to decide jointly, therefore, any change in a characteristic curve can achieve the purpose of regulating the flow rate. at present, flow control of a centrifugal pump are the main method of regulating valve control, speed control and pump, etc. and regulation of series. due to the variety of regulation the principle is different, in addition to have their own advantages and disadvantages, resulting in energy loss is not the same, in order to seek the best, the minimum energy consumption, the energy flow rate regulation, must fully understand the stainless steel centrifugal pump flow adjustment and energy consumption of the relationship between.
