Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gas storage tanks, and in particular relates to a gas storage tank for an air compressor. Background Art
[0002] Air compressor receivers have the ability to regulate system airflow fluctuations. They store intermittent compressed air and release it during peak demand, ensuring stable and continuous output airflow. This reduces the number of compressor starts and stops. When the system airflow demand is low, the receiver acts as a buffer, providing the required airflow and reducing the number of compressor starts and stops. This not only helps reduce energy consumption but also extends the life of the equipment.
[0003] However, existing gas storage tanks usually discharge the liquid mixture at the bottom directly, and the discharge contains condensate, oil-water mixture and iron filings from the inside of the air compressor. Direct discharge will cause environmental pollution. Utility Model Content
