Name:polished rod

Product Description

 The polished rod is a specially designed "sucker rod" for the connection between the sucker rod and the suspender.
Because it is at the top of the sucker rod, the force is the largest, so the diameter of the polished rod is larger than that of the sucker rod, the grade of steel is higher, and the surface is more smooth.
Main functions are: 1. Combined with the packing box, seal the well head to prevent oil, gas and water leakage.
2. Realize the connection transition between the sucker rod and the suspender.
3. Complete the indicator diagram test.
4. Realize various operations of the well head.
If touch pump, adjust pump hang, etc.
