不(bú)鏽鋼離心泵是(shì)廣泛應用于化(huà)工工(gōng)業系統的(de)一種通用(yòng)流(liú)體機械(xiè)。 不鏽鋼離(lí)心泵 具(jù)有(yǒu)性能(néng)适應範圍廣包(bāo)括(kuò)流量、壓頭及對輸(shū)送(sòng)介質性(xìng)質的适應性、體積小(xiǎo)、結構簡單、操作(zuò)容易、操作(zuò)費用低等諸多(duō)優點。通常，所選(xuǎn)離心(xīn)泵的流量(liàng)、壓頭可(kě)能(néng)會和管路(lù)中要(yào)求的(de)不一緻，或由于(yú)生産任務、工藝(yì)要求發生(shēng)變化(huà)，此時(shí)都要求對泵進(jìn)行流量調節，實質是(shì)改變(biàn)離心泵的(de)工作點。離(lí)心(xīn)泵的工(gōng)作點是由(yóu)泵的(de)特性曲線和管(guǎn)路系統特性曲(qǔ)線共同決(jué)定的(de)，因此，改變(biàn)任何一個(gè)的特性曲(qǔ)線都可以達到流量調節的目(mù)的。目前，離心泵(bèng)的流(liú)量(liàng)調(diào)節方(fāng)式主要有調節閥控(kòng)制、變速控(kòng)制以(yǐ)及泵(bèng)的并(bìng)、串聯調節等。由(yóu)于各種調(diào)節方式的原(yuán)理不同(tóng)，除有自(zì)己的優(yōu)缺(quē)點外(wài)，造成的(de)能量損(sǔn)耗也不(bú)一樣(yàng)，爲了尋求(qiú)佳、能(néng)耗小、節能的流量(liàng)調節方(fāng)式(shì)，必(bì)須全(quán)面地(dì)了解(jiě) 不鏽鋼離(lí)心泵 的流(liú)量調(diào)節方(fāng)式與能耗(hào)之間的關系(圖(tú)\文 xiaojikuaipao.top/index.asp )。
中(zhōng)譯(yì)英：
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 including flow, pressure head and the conveying medium nature of adaptability, 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.
