管柱脱落的故障现象是：运行电流很低，基本上是电机的空载电流，除了有一股一股的气外，井口基本上无产液，正发循环时油套连通。The failure phenomenon of the string is: the running current is very low， basically the motor"s no load current. Besides the gas with a single strand of gas， the wellhead basically has no liquid production， and the oil sleeve is connected when circulating.减少管柱脱落的措施有：将油管上扣扭矩由原来的值提高到值；采用油管螺纹垫片；定子上的装卸短节采用防松螺纹连接；采用油管锚或张力封隔器固定螺杆泵。The measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading and unloading joint on the stator is connected by loosening screw thread; and use the oil pipe anchor or tension packer to fix the screw pump.



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，mono，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 prevent it from falling into the overhead and lose its function and prevent the rod from falling into the bottom when the rod string falls off.



 单螺杆泵类别：    泵从大类分为两种：容积泵和流量泵。    容积泵：通过泵的传动部件形成的空腔转运流体，传动部件的转动移出流体分为往复式和旋转式两大类    流量泵：带给流体动能，流体转运和循环；不允许干运行，液面以下运转单螺杆泵特点：    1、在低转速工况下压力稳定    2、低必须气蚀余量    3、可输送含大颗粒的介质    4、可输送含磨蚀性的介质    5、压力可至48B    6、流量稳定、可用于计量加药    7、流量对介质的粘度高低影响不大    8、只有一处轴封、便于检修
