The crankshaft of the oilfield pumping unit is subjected to alternating loads, and the journal is prone to fatigue wear, resulting in the operation of the pumping unit being stuck and the oil recovery efficiency decreasing by 15%. Daokedao adopts mobile laser cladding equipment for on-site operations in oil fields, using Cr Ni Mo alloy powder that is resistant to oil and gas corrosion. The thickness of the journal cladding layer is 0.2mm, the hardness is HRC58-62, and the fatigue strength is increased by three times. Repair the roundness error of the rear axle neck to ≤ 0.005mm, control the clearance between 0.01-0.02mm, and improve the smooth operation of the pumping unit by 90%. For the Φ 180mm crankshaft, the repair cycle is only 48 hours, the cost is 25% of the new shaft, and the service life reaches 90% of the new shaft. After application in a certain oil field, the oil recovery efficiency of the pumping unit increased from 85% to 98%, the downtime for faults was shortened from 10 hours per month to 1 hour, and the annual oil production of a single well increased by 100 tons. The equipment is equipped with explosion-proof design, which complies with oilfield safety standards and is suitable for repairing crankshafts of various pumping units such as beam type and screw type.
