不鏽鋼(gāng)離心泵調節方(fāng)式與(yǔ)能(néng)耗(hào)的分(fèn)析

不(bú)鏽(xiù)鋼(gāng)離心(xīn)泵(bèng)是廣(guǎng)泛應用(yòng)于化工工(gōng)業系(xì)統的一(yī)種通用(yòng)流體機(jī)械(xiè)。 不鏽(xiù)鋼離(lí)心泵(bèng) 具有性能适應範圍(wéi)廣、體積小(xiǎo)、結構簡單、操(cāo)作容易、操作(zuò)費(fèi)用低等(děng)諸多優點(diǎn)。通常(cháng)，所(suǒ)選離心泵的(de)流量、壓頭(tóu)可(kě)能會和管路中要(yào)求的不(bú)一緻，或(huò)由于(yú)生産(chǎn)任務(wù)、工藝要求(qiú)發生變化，此時都要(yào)求對泵進行流(liú)量調節，實質是(shì)改變(biàn)離心(xīn)泵的(de)工作(zuò)點(diǎn)。離心泵(bèng)的工作點是由泵的(de)特性曲線(xiàn)和管路系統特(tè)性曲(qǔ)線共同決(jué)定的(de)，因此(cǐ)，改變(biàn)任何(hé)一個的特(tè)性曲線都可以達到流量調節(jiē)的目(mù)的。目前，離(lí)心(xīn)泵(bèng)的流量調(diào)節方式主要有調節閥控(kòng)制、變(biàn)速控制(zhì)以及泵(bèng)的并、串聯調節(jiē)等。由于各種調(diào)節方式的原理不同，除有自己(jǐ)的優缺點外，造(zào)成的(de)能(néng)量損耗也(yě)不一(yī)樣，爲了(le)尋求佳、能耗小(xiǎo)、節能的流(liú)量調節方式(shì)，必須全(quán)面地(dì)了解(jiě) 不鏽(xiù)鋼(gāng)離心泵 的流量調(diào)節方式與能耗之間(jiān)的關系(圖(tú)\文 xiaojikuaipao.top/ )。
中譯英(yīng)：
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.
