Technical Field
The invention belongs to the technical field of aviation oil equipment, and particularly relates to a mobile low-point aviation oil discharging device and a low-point aviation oil discharging method.
Background
A low point discharge system for aviation fuel is a device for discharging free water accumulated in aviation fuel. When the fuel in the tank or pipe is cooled, water vapor in the fuel condenses and forms water droplets. These water droplets accumulate at the bottom of the tank and eventually lead to an increase in the water level at the bottom of the tank or pipe handling equipment. The purpose of the low point drain system is to drain these water droplets from the tank or pipe handling equipment to keep the tank or pipe handling equipment clean and safe. The principle of the low point discharge system is to use gravity to drain the water droplets from the tank or tubing. When the water level in the tank or pipe plant rises to a low point drain, water droplets will flow out of the drain while fuel continues to remain in the tank or pipe plant. The drain is typically located at a lower bottom of the tank or tubing so that the water droplets can flow out smoothly.
