螺桿泵工作特點(diǎn):結(jié)構(gòu)簡(jiǎn)單、工作、使用維修方便、出液連續(xù)均勻、壓力穩(wěn)定,噪聲和振動(dòng)小,有自吸能力,但螺桿加工較困難。
螺桿泵適用場(chǎng)合:輸送潤(rùn)滑油,輸送燃油,輸送各種油類及高分子聚合物,適用于輸送黏稠液體。
輸送高粘度介質(zhì):根據(jù)泵的大小不同可以輸送粘度從37000-200000厘泊的介質(zhì)。
輸送含有顆粒或纖維的介質(zhì):顆粒直徑可以這30mm不超過(guò)轉(zhuǎn)子偏心距。纖維長(zhǎng)可以350mm相當(dāng)0.4位轉(zhuǎn)子的螺距。其含量一般可達(dá)介質(zhì)窖的40%,若介質(zhì)中的固體物為細(xì)微之粉沫狀時(shí),含量可達(dá)60%或更高也能輸送。
要求輸送壓力穩(wěn)定,介質(zhì)固有結(jié)構(gòu)不受破壞時(shí),選用單螺桿泵輸送為理想。
空心轉(zhuǎn)子優(yōu)勢(shì):
advantages of hollow rotor:
1.空心轉(zhuǎn)子重量減輕后,與常規(guī)轉(zhuǎn)子的軸向扭力減弱,啟動(dòng)扭矩降低,減速電機(jī)選型偏小,客戶使用成本---降低,達(dá)到節(jié)能效果。
1. after the weight of the hollow rotor decreases, the axial
torsion of conventional rotor will recede, break-out torque will lower, gear
motor type will be relatively small, as well as customers use cost will
greatly lower with effect of environmental protection&energy saving
obtained.
2.因摩擦力與重量有密切關(guān)聯(lián),因此與同等實(shí)心轉(zhuǎn)子對(duì)比,重量減輕后,泵在運(yùn)行過(guò)程中轉(zhuǎn)子摩擦力減弱,使用壽命同比增大。
2. because the force of friction is closely related to
weight, the force of friction of the rotor lowers&service life increases on
a year-on-year basis in the operation process of the pump after the weight1
decreases in comparison to the equivalent solid rotor.
