武汉莫诺螺杆泵配件诚信企业「螺耐斯」[螺耐斯10e361c]内容: 管柱脱落是自由式管柱结构经常发生的一种现象,这是由于正常运转时转子旋转对定子产生的摩擦扭矩方向实际上是定子及油管的连接螺纹的卸扣方向,如果摩擦力矩大于油管扣的上扣扭矩,油管就脱扣。当尾管很重时,还会出现螺纹掳扣。当管柱脱落时,通过作业重新连接好就能恢复生产。如果未发生螺纹掳扣,可以采取对扣方式打捞,如果发生掳扣,必须下打捞工具进行打捞。Column shedding is a common phenomenon of free tube structure, which is due to the direction of rotation of the friction torque generated by the stator rotor during normal operation is actually a stator and tubing connection1 screw shackle direction, if the friction torque is greater than the pipe le on torque, oil pipe tripping. When the tail pipe is very heavy, there will also be a thread caption. When the pipe column falls off, the production can be restored by reconnecting the work. If the le is not threaded, it can be salvaged by the way of the le. If the le occurs, the fishing tool must be salvaged.

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.

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

在使用一段时间的单螺杆泵吸不上液体很有可能是定子和转子损坏所致,检查更换新的定子或者转子就可以了。 进出口管道上的阀门没有打开或开度不够,打开进出口阀门就可以了。 填料密封的单螺杆泵有可能是填料磨损、机械密封的螺杆泵有可能机械密封面损坏或磨损,压紧或更换填料,机械密封损坏更换新的机械密封就可以了。

G型单螺杆泵型号在我国20世纪50年代就已生产,近年来G型单螺杆泵型号技术及其应用发展较快。G型单螺杆泵型号属于容积式泵,从结构上分:单螺杆泵、双螺杆泵、三螺杆泵及船用螺杆泵。其中双螺杆泵及三螺杆泵属于典型的工业泵类,本文所述的螺杆泵就指的是这两种泵。两者的工作原理基本相同,使用场合相似,区别在于双螺杆泵输送的介质粘度范围更宽些,且适用于非牛顿流体的输送。两者总效率相差不大,但双螺杆泵的容积率略低于三螺杆泵。
