Product Description

Product name: sucker rod coupling centralizer (KZX preventing eccentric wear centralizer)

Product overview: KZX anti-eccentric centralizer is a new kind of preventing oil-well eccentric wear of patent product which has the characteristics of simple structure, convenient use, long service life, low cost. It is applicable to eccentric wear pumping well, especially suitable for sucker rod above the neutral point of the eccentric wear of pumping unit well and directional shafts. Below part the neutral point of sucker rod is fitted with nylon centralizer of sucker rod body with eccentric wear prevention effect. The centralizer is also applicable to the screw pump rod centralizer.

The structure as shown in figure:

1, coupling 2, ring gear 3, righting sleeve 4, ring gear 5, nipple

Working principle: the centralizer is connected on the sucker rod, the outer diameter of righting sleeve is greater than the outer diameter of the sucker rod coupling, thus playing righting effect; the centralizer is high strength wear-resistant plastic, connecting with the tubing making centralizer body worn, and reduce tubing wear to achieve the purpose of preventing eccentric wear. The righting sleeve rotates and uniformly wears by straight teeth and helical groove, so as to achieve the purpose of long service life .

Technical parameters:

1. Righting sleeve (Rockwell hardness R): 85-114

2. The righting sleeve compression strength: 60-90MPa

3. Connecting buckle type:

19, 22, 25mm sucker rod thread type

4. The largest outside diameter: 58, 58, 72mm

5. The total length: 343348370 mm

6. The medium temperature: 0-100 º C

Principles:

1. The eccentric wear lighter section, installing a set of 3 root sucker rod.

2. Eccentric wear heavier section, installing a set of 2 root sucker rod.

3. Eccentric wear heavy section, each installing a set of 1 root sucker rod.

4. Eccentric wear serious section (and turning points), and installing a set of 1 root sucker rod,

installing nylon centralizer in the middle of the pumping also.

Methods:

1. Checking whether the KZX preventing eccentric wear centralizer is qualified products (with and without cracks,whether rotation is flexible, etc.).

2. According to the well pipe rod combination structure and the eccentric wear condition choose corresponding KZX type preventing eccentric wear of centralizer specification and quantity.

3. When used, back plier is put on the pumping style, wrench is tighten by the flat body on the below of centralizer; pipe wrench is put on the centralizer coupling (that is, three teeth ring), pipe wrench on the pumping style is tighten. The upper torque should be 0.53KN m (19), 0.79 KN. m(22) and 1.0 KN. m(25).

4. When puts down the centralizer to the well, installing sucker rod guide on the well's mouth.

5. When put down, keeping balance, and the speed should be less than 8 m/min.

6. When pulls up out of the centralizer, back plier is put on rod side body, pipe wrench of the flat body on the below of centralizer is taken off, making sure that the centralizer non-deformation or loose.

7. A righting sleeve of the centralizer is worn off two-thirds, and damage, deformation, the phenomenon such as not flexible rotation should be replaced.
