武汉莫诺螺杆泵配件信赖推荐「螺耐斯」yes or no主角

3分钟前 武汉莫诺螺杆泵配件信赖推荐「螺耐斯」[螺耐斯10e361c]内容：杆柱脱落Rod shedding杆柱脱落也是螺杆泵常发生的一种故障现象，表现为运行电流很低，井口也无产液，正反循环油套不连通，通过对扣或下入抽油杆打捞工具就可以进行处理来恢复生产。抽油杆脱落也有两种情况，一是脱扣，一是掳扣。造成脱扣的原因是停机后抽油杆柱扭转变形余能释放引起杆柱反转，可以采取在地面和抽油杆柱上安装防倒装置进行防止。造成杆柱掳扣的原因有三个：一个是稠油井在长时间关井后再启泵时，启动扭矩特别大，把螺纹损坏了；一个是油特别稠，螺杆泵长期在高扭矩下工作而把螺纹损坏；再有一个原因是定子部分脱胶，转子转不动造成的。

Ｂ、转子B, rotors转子的结构也非常简单，主体是钢制杆件，一般外涂耐磨耐蚀的铬合金材料。其作用是传递动力和写定子形成密封腔。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、回转筒C, rotary barrel回转筒也就是一根内径较大的油管或空心定子筒，接在定子的上部以给转子和抽油杆杆柱以较大的回旋空间，防止转子和抽油杆因偏心运动磨擦磨损油管。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.

Ｄ、限位器D, limiting device限位器为一个底部带限位板和流通通道的短节，接在定子的尾部，其作用是施工作业时给转子限位以防止下入过头而失去作用和杆柱脱落时防止杆柱掉入井底。The limiting device is a short section with bottom limit plate and distribution channel, which is connected to the tail of the stator. Its function is to limit the rotor to the rotor during ctruction1, so as to pvent it from falling into the overhead and lose its function and pvent the rod from falling into the bottom when the rod string falls off.
