不鏽鋼離心(xīn)泵調(diào)節方式與(yǔ)能(néng)耗的分析

不鏽鋼(gāng)離心泵是廣泛應用于化工工業系統的一種通用流體機械。 不鏽鋼離(lí)心泵 具(jù)有(yǒu)性能适應範圍廣、體積小、結構簡單、操作容易、操作費(fèi)用低等(děng)諸多優點。通常，所選離心泵的(de)流量、壓頭可能會和管(guǎn)路(lù)中要求的不一緻，或由于(yú)生産任務、工藝要求發生(shēng)變化，此時都要求對泵進行流量調節，實質是改變離心泵的工作點。離心泵的工作點是(shì)由泵的特性曲線和管路系統特性曲線共同決定的，因此，改變(biàn)任何一(yī)個的特性曲線都可以達到流量調(diào)節的目的。目前，離心泵的流量調(diào)節方式主要有調節閥控制、變(biàn)速控制以及泵的并、串聯調節等。由于各種調節方式(shì)的原理(lǐ)不同，除有自(zì)己的優缺點外，造成的(de)能量(liàng)損耗也不一樣，爲了尋求佳、能耗小、節能的流量(liàng)調節方式，必須全面地了解 不鏽(xiù)鋼(gāng)離心泵 的流量調節方式與能耗之間的關系(圖\文 xiaojikuaipao.top/ )。
中(zhōng)譯英：
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, 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.
