The flatness and wear resistance of the sealing surface of the oil column plug directly affect the sealing effect. Long-term reciprocating motion will easily cause the wear and scratches of the sealing surface, and cause the leakage fault, not only reducing the pumping efficiency, but also polluting the environment. The traditional grinding repair effect is short, the sealing surface is easy to be worn again, and the replacement of a new plunger requires a long shutdown time, which affects the oil field production.
Dow laser cladding equipment adopts ultra-fine alloy powder according to the strengthening requirements of the sealing surface of the column plug, and forms a uniform and smooth wear-resistant coating on the sealing surface through laser cladding technology. The roughness of the coating surface Ra ≤ 0.2 μ m, the flatness error ≤ 0.01mm, and the coating is closely fitted with the sealing elements, greatly improving the sealing performance.
The hardness of the coating can reach over HRC65, the wear resistance is 4 times of the original material, the service life of the sealing surface is extended by 5-6 times, and the leakage failure rate is reduced by over 90%. The equipment supports local accurate cladding of the sealing surface, and the repair cycle is shortened to 12 hours. It is unnecessary to replace the plunger as a whole, greatly reducing the operation and maintenance cost and shutdown loss of the oil field.
