調(diào)節(jié)水泵流量的方法,調(diào)節(jié)水泵流量的方法,調(diào)節(jié)水泵流量
zui普通的調(diào)節(jié)水泵流量的方法就是關(guān)小水泵出口閥門來調(diào)節(jié)流量、但是這只是針對(duì)常規(guī)的離心泵類的產(chǎn)品,如果采用的是螺桿泵或者柱塞泵、容積泵類產(chǎn)品就不能使用關(guān)小出口閥門調(diào)節(jié),只能關(guān)小進(jìn)口閥門來調(diào)節(jié)流量,關(guān)小閥門來達(dá)到調(diào)小流量的方法我們并不提倡、因?yàn)檫@樣達(dá)不到節(jié)能的效果,工況需要的流量不穩(wěn)定,調(diào)節(jié)水泵流量的方法我們建議選用目前zui為新穎的變頻調(diào)流方法zui為合適,因?yàn)轭l率降低之后轉(zhuǎn)速將會(huì)降低從而消耗功率也就降低了。根據(jù)不同工況選擇不同的變頻水泵才能達(dá)到預(yù)期的效果,常用的變頻泵類產(chǎn)品參考如下:
一、變頻離心泵
變頻離心泵主要適應(yīng)與生活供水用、用水量較大時(shí)變頻離心泵出口電接點(diǎn)壓力表會(huì)自動(dòng)反饋給變頻柜信號(hào)調(diào)高頻率使其轉(zhuǎn)速加大達(dá)到所需流量、當(dāng)用水量較小時(shí)相反之使其轉(zhuǎn)速降低流量變小,變頻離心泵與普通離心泵不同之處就是電機(jī)多加了一個(gè)工頻風(fēng)扇為電機(jī)降溫以避免轉(zhuǎn)速降低之后電機(jī)自身的風(fēng)扇達(dá)不到降溫的效果。

二、變頻螺桿泵
變頻螺桿泵主要是運(yùn)用與輸送一些高粘度的液體、并且同樣需要調(diào)節(jié)水泵流量、因?yàn)橐恍┕r環(huán)境流量不是需要穩(wěn)定性而是需要可調(diào)節(jié)的范圍,變頻螺桿泵優(yōu)點(diǎn)就是在調(diào)節(jié)轉(zhuǎn)速的情況下壓力是穩(wěn)定的只是流量有變化,所以采用變頻螺桿泵的好處就是揚(yáng)程穩(wěn)定不會(huì)像離心泵一樣轉(zhuǎn)速變后揚(yáng)程就變了。
