8分鐘前 武漢莫諾螺桿泵配件值得信賴 螺耐斯[螺耐斯10e361c]內(nèi)容：Ｂ、轉(zhuǎn)子B, rotors轉(zhuǎn)子的結(jié)構(gòu)也非常簡單，主體是鋼制桿件，一般外涂耐磨耐蝕的鉻合金材料。其作用是傳遞動(dòng)力和寫定子形成密封腔。The structure of the rotor is also very simple, the main body is steel rod, generally coated with abrasion resistant and corrosion resistant chromium alloy material. Its function is to transfer power and write the stator to form a seal cavity.Ｃ、回轉(zhuǎn)筒C, rotary barrel回轉(zhuǎn)筒也就是一根內(nèi)徑較大的油管或空心定子筒，接在定子的上部以給轉(zhuǎn)子和抽油桿桿柱以較大的回旋空間，防止轉(zhuǎn)子和抽油桿因偏心運(yùn)動(dòng)磨擦磨損油管。A rotary cylinder is also an oil tube or hollow stator barrel with larger inner diameter. It is connected to the upper part of the stator to provide larger swirl space for the rotor and sucker rod string, so as to pvent the rotor and sucker rod from attrition wear due to eccentric wear.

單螺桿泵有以下優(yōu)點(diǎn)：

1)因?yàn)楸脙?nèi)的回轉(zhuǎn)部件慣性力較低，故可使用很高的轉(zhuǎn)速;

2)結(jié)構(gòu)堅(jiān)實(shí)，安裝保養(yǎng)容易;

3)單螺桿泵的壓力和流量范圍寬闊。壓力約在3.4-340千克力/cm2，流量可達(dá)18600cm3/分;

4)單螺桿泵的吸入性能好，具有自吸能力;

5)與其它回轉(zhuǎn)泵相比，對進(jìn)入的氣體和污物不太敏感;

6)流量均勻連續(xù)，振動(dòng)小，噪音低;

7)單螺桿泵的運(yùn)送液體的種類和粘度范圍寬廣。

單螺桿泵的缺點(diǎn)是，螺桿的加工和裝配要求較高;泵的性能對液體的粘度變化比較敏感。

單螺桿泵類別： 泵從大類分為兩種：容積泵和流量泵。 容積泵：通過泵的傳動(dòng)部件形成的空腔轉(zhuǎn)運(yùn)流體，傳動(dòng)部件的轉(zhuǎn)動(dòng)移出流體分為往復(fù)式和旋轉(zhuǎn)式兩大類 流量泵：帶給流體動(dòng)能，流體轉(zhuǎn)運(yùn)和循環(huán)；不允許干運(yùn)行，液面以下運(yùn)轉(zhuǎn)單螺桿泵特點(diǎn)： 1、在低轉(zhuǎn)速工況下壓力穩(wěn)定 2、低必須氣蝕余量 3、可輸送含大顆粒的介質(zhì) 4、可輸送含磨蝕性的介質(zhì) 5、壓力可至48B 6、流量穩(wěn)定、可用于計(jì)量加藥 7、流量對介質(zhì)的粘度高低影響不大 8、只有一處軸封、便于檢修
