不(bú)鏽鋼(gāng)離心泵是(shì)廣泛應用于化(huà)工工業系統的一種通(tōng)用(yòng)流體機械(xiè)。 不鏽鋼離心泵 具有(yǒu)性能适應(yīng)範圍廣、體(tǐ)積小、結構(gòu)簡單(dān)、操作(zuò)容(róng)易、操作(zuò)費用(yòng)低等諸多優點。通常(cháng)，所選(xuǎn)離心泵的(de)流量(liàng)、壓頭(tóu)可(kě)能(néng)會和(hé)管路中(zhōng)要求的(de)不一(yī)緻，或(huò)由于生産任(rèn)務、工藝要求發生變化，此時都要求對(duì)泵進行流(liú)量調(diào)節，實質是(shì)改變離心(xīn)泵(bèng)的工作(zuò)點。離心泵的工(gōng)作點(diǎn)是由(yóu)泵的(de)特性曲線和管路系(xì)統特性曲(qǔ)線共(gòng)同決(jué)定的(de)，因此，改變任何(hé)一個的特(tè)性曲線都可(kě)以達到(dào)流量(liàng)調節的目的。目前，離心泵(bèng)的流量(liàng)調節方式主(zhǔ)要有(yǒu)調節(jiē)閥控制(zhì)、變速控制以及泵的并(bìng)、串聯調(diào)節等。由于各種(zhǒng)調節方(fāng)式的原(yuán)理不同(tóng)，除有自(zì)己的優(yōu)缺點(diǎn)外，造成的(de)能量(liàng)損耗也不(bú)一樣(yàng)，爲了尋求佳、能(néng)耗小(xiǎo)、節能(néng)的流(liú)量(liàng)調節方(fāng)式，必(bì)須(xū)全面地(dì)了解 不鏽鋼離(lí)心泵(bèng) 的流量(liàng)調(diào)節方(fāng)式與能耗(hào)之間的關系(圖(tú)\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.
