Description

Technical Field

[0001] The utility model relates to the technical field of sucker rod descaling, in particular to a mechanical rotary brush composite descaling device for repairing a sucker rod. Background Art

[0002] A sucker rod is a device used to extract oil or natural gas. It usually consists of a set of connected cylindrical rods that extract oil or natural gas underground by moving up and down. The sucker rod is usually made of high-strength, corrosion-resistant materials such as steel. In the oil well, the sucker rod is connected to the pump and drive device. By pumping in liquid or gas, the oil or natural gas in the underground reservoir is pushed to the surface. This is one of the important tools in the process of oil or natural gas extraction.

[0003] After long-term use, various dirt will adhere to the surface of the sucker rod. The sticky dirt adheres to the sucker rod. The dirt will affect the quality of the sucker rod during operation, and the sucker rod needs to be cleaned. The existing sucker rod is cleaned by chemical immersion cleaning, which takes a long time. High-pressure water cleaning is faster, but the dirt is not removed cleanly. In addition, because the sucker rods also have different sizes and models, it is difficult to fix them during cleaning, which makes it easy for the sucker rod to be knocked down during high-pressure water cleaning and cause secondary damage.
