當(dāng)然，也可以制造轉(zhuǎn)子和定子螺旋頭數(shù)更多的單螺桿泵，如三頭螺旋的轉(zhuǎn)子和四頭內(nèi)螺旋定子構(gòu)成的泵等，但對制造精度的要求更髙，且流量并不是總隨螺旋頭 </p> <p> <br /> </p> <p> 增加而增大，故已無多少實際意義。雖然這種更多螺旋頭數(shù)的轉(zhuǎn)子和定子的嚙合副在單螺桿泵中并沒有得到應(yīng)用，但在石油機械的螺桿鉆具這一領(lǐng)域卻得到了***的應(yīng)用。 </p> <p> <br /> </p> <p> <br /> </p><p> 螺桿泵定子加工流程簡介，螺桿泵定子加工大致分為以下幾步： </p> <p> 1.螺桿泵定子外殼加工： </p> <p> 螺桿泵定子的外殼常為鋼管，我們需要按圖紙切割毛培鋼管，然后放車床進行加工。 </p> <p> 一般都是用鋸床來進行切割：2.開好對應(yīng)定子的轉(zhuǎn)子模具 </p> <p> 在對定子加工前，我們都會把模具做好，如果沒有配合模具，得把模具做好。3.注膠 </p> <p> 使用模具配合，利用壓膠機往模具里壓膠，當(dāng)膠填滿時，停止壓膠。4.對螺桿泵定子進行硫化 </p> <p> 將帶模具的定子一起放入硫化箱進行一段時間硫化。5.拆模具 </p> <p> 取出模具，開始拆卸模具。6.對螺桿泵定子外殼進行噴漆。 </p> <p> <br /> 單螺桿泵的安裝位置可以任意傾斜.</p><div style="width:100%;text-align:

Q：計量螺桿泵自動控制變頻電機+變頻器與通過自動沖程控制器來實現(xiàn)的自動控制區(qū)別在哪？ </p> <p> <br /> </p> <p> A：”2種方式**終結(jié)果都是調(diào)節(jié)螺桿泵的流量，區(qū)別就是，變頻電機+變頻器是通過改變電機頻率(轉(zhuǎn)速)，實現(xiàn)調(diào)節(jié)流量的效果；自動沖程變速器是通過改變螺桿泵的行程(電機轉(zhuǎn)速不變)，實現(xiàn)現(xiàn)調(diào)節(jié)流量的效果?！?</p> <p> <br /> </p> <p> Q：液壓隔膜計量螺桿泵是否可以配自動沖程變速器呢？ </p> <p> <br /> </p> <p> A：目前我們只有GB/GM2個系列的機械隔膜計量螺桿泵，才能加裝自動沖程控制器 </p> <p> <br /> </p> <p> Q：計量螺桿泵安裝什么情況下得加背壓閥？背壓閥起什么作用？ </p> <p> <br /> </p> <p> A：當(dāng)計量螺桿泵的進口壓力大于出口壓力的時候，必須加裝背壓閥，否則，進口壓力會將計量螺桿泵單向閥內(nèi)的球頂開，起不到密封的效果，這臺螺桿泵是失效了，我們稱該現(xiàn)象為虹吸現(xiàn)象。 </p> <p> <br /> </p> <p> Q：計量螺桿泵調(diào)節(jié)在多少范圍內(nèi)重復(fù)精度可達(dá)正負(fù)1%？ </p> <p> <br /> </p> <p> A：計量螺桿泵在10%-90%的調(diào)節(jié)范圍內(nèi)，能達(dá)到正負(fù)1%的重復(fù)精度。 </p> <p> <br /> </p> <p> Q：請問廠里JLM電磁驅(qū)動小型微型計量螺桿泵可以做230v嗎？ </p> <p> <br /> </p> <p> A：JLM電磁驅(qū)動小型微型計量螺桿泵只有220V電壓。 </p> <p> <br /> 拆卸泵頭，卸下泵頭固定螺母，取下泵頭。陽江口碑好螺桿泵</p><p style="text-indent:25px">拆卸轉(zhuǎn)子、連桿、短節(jié)、密封盒先卸下三通。全國直銷螺桿泵</p><p> (一）腐蝕的基本概念 </p> <p> <br /> </p> <p>
