Pumping wellhead polished rod sealing and anti-eccentric wear have always been difficult problems in oil recovery technology. The commonly used technology in sites basically belong to the two categories of manual and semi-automatic anti-eccentric, but the effect is not satisfied. This product uses a combination of eccentric correction and adjustment, the self-lubricating packing material and polished rod protection sleeve, and a more reasonable structural design, which reduces the friction coefficient between polished rod and packing, significantly improves the sealing and anti-eccentric wear effects, and extends the packing working time, simplified operation and reduced well stop time.
1.Main features and advantages
2.Specifications:
It is suitable for Φ26、Φ28、Φ32、Φ36、Φ38、Φ42、Φ45 polished rod.
3.Steps
(1).The polished rod should be checked before pumping. There should be no burrs and the oil contamination should be removed, meanwhile, a layer of butter or motor oil should be applied to the polished rod to prevent dry grinding.
(2).Put the sealing device into the polished rod , then connect the universal ball joint assembly seat to the wellhead (note: When the finished product is delivered, the parts are assembled and adjusted well, and cannot be disassembled) and locking. tapered packing , rectangle packing are packed into the cavity (at least 4 rectangular packing with a thickness of 20mm must be assembled), as shown in the figure, press the packing pad , And then turn the pressure cap clockwise. After the oil comes out, turn the pressure cap to make an appropriate adjustment until no oil leaks.
