ｅ、抽油杆扶正器e， ---er rod centralizer抽油杆扶正器由心轴和扶正筒组成，它接在两根抽油杆之间，被卡在两个抽油杆接箍之间。心轴也就是一要极短的抽油杆短节。扶正筒是一个内孔比心轴大１ｍｍ左右的空心塑料筒，外部有四个略比油管内径小的扶正翼，采取浇注成型。扶正筒可以围绕心轴转动，防止抽油杆旋转时与内壁接触而磨蚀油管，又可以让流体通过。the ---er rod centralizer is comed of the heart shaft&the upright cylinder，mono， which is connected between the two ---er rods&is stuck between the two ---er rod hoops. the axis of the heart is also an extremely short rod short section. the ws=ing cylinder is a hollow plastic tube inner hole bixin shaft around 1mm， external four slightly smaller than the diameter of the tubing centralizer wing， adopt casting. the centralizer can revolve around the axis to prevent the ---er rod from touching the inner wall when it rotates，&it can also let the fluid pass through.
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 motors no load current. besides the gas with a single strand of gas， the wellhead basically has no liquid production，&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&unloading joint on the stator is connected by loosening screw thread;&use the oil pipe anchor/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---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&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&lose its function&prevent the rod from falling into the bottom when the rod string falls off.
