卡箍类插入型、防滑型扶正器
Inserted and Anti-skid Clamp Centralizer

      该产品是由两个半圆体相结合（可嵌入骨架），利用其中一个半圆体中的斜形导轨，插入另一个半圆体中的凹槽中，借用内孔中的凸条与抽油杆抱紧的组合结构。
      该产品是在原有产品的基础上，为了解决该扶正器可在抽油杆上滑窜的技术弊端，将其中的一个半圆体增加了一个可容抽油杆突缘部位空间，使其限定在突缘部位，对卡在抽油杆上后即能扶正杆管，又能防止滑窜。

       This is made by combinimg two half cylinders (inlayingstructure).lnsert the diagonal guiding track of one half cylinder into the fluted area of another half cylinder. The structure closely fits the sucker rod through the projecting point inside or the raised line of the screw. This is product overcomes the slipping problem of the centralizer. A space for the flange of the sucker rod is reserved in one of the half cylinders,so that the half cylinder is fixed at the flange. lt can centralize the rod and prevent slipping after being clipped on the sucker rod.
