空心轉子優(yōu)勢:
Advantages of hollow rotor:
1.空心轉子重量減輕后,與常規(guī)轉子的軸向扭力減弱,啟動扭矩降低,減速電機選型偏小,客戶使用成本大大降低,達到環(huán)保節(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 customer's use cost will
greatly lower with effect of environmental protection and energy sing
obtained.
2.因摩擦力與重量有密切關聯(lián),因此與同等實心轉子對比,重量減輕后,泵在運行過程中轉子摩擦力減弱,油井泵空心轉子,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 and 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.

螺桿泵工作特點:結構簡單、工作、使用維修方便、出液連續(xù)均勻、壓力穩(wěn)定,噪聲和振動小,有自吸能力,但螺桿加工較困難。
螺桿泵適用場合:①輸送潤滑油,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。
②輸送高粘度介質:根據(jù)泵的大小不同可以輸送粘度從37000-200000厘泊的介質。
③輸送含有顆?;蚶w維的介質:顆粒直徑可以這30mm(不超過轉子偏心距)。纖維長可以350mm(相當0.4位轉子的螺距)。其含量一般可達介質窖的40%,若介質中的固體物為細微之粉沫狀時,含量可達60%或更高也能輸送。
④要求輸送壓力穩(wěn)定,介質固有結構不受破壞時,選用單螺桿泵輸送為理想。
