Explosion-proof rating: Downhole equipment must comply with GB 3836 series standards and possess ExdⅠ or ExdⅡ level explosion-proof certification to prevent gas or dust explosions.
Energy efficiency ratio: Equipment with an energy efficiency ratio (EER) ≥ 3.0 should be prioritized to reduce long-term operating costs.
Corrosion resistance: The humid environment downhole easily leads to equipment corrosion; stainless steel or anti-corrosion coatings are required.
Maintenance convenience: Modular design can shorten downtime for maintenance; for example, removable condensers facilitate cleaning.
