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、因為這樣達(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,因為頻率降低之后轉(zhuǎn)速將會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、用水量較大時變頻離心泵出口電接點壓力表會自動反饋給變頻柜信號調(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、因為一些工況環(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程穩(wěn)定不會像離心泵一樣轉(zhuǎn)速變后揚程就變了。
