Micro pumps can also work in a closed environment. Here is some information about the application of micro pumps in a closed environment:

1. Characteristics of water pumps in a closed environment:

- Usually driven by a brushless DC motor, it can work in an environment with thin oxygen or no oxygen.

- Small size and light weight, suitable for installation in a small or restricted space.

- Low noise and low power consumption, suitable for occasions with requirements for noise and power supply.

- Strong waterproof and dustproof properties, can work for a long time in a humid or dusty environment.

2. Application scenarios of micro pumps in a closed environment:

- Cooling circulation system inside electronic equipment

- Liquid supply system for wearable devices or medical devices

- Cooling and lubrication system of closed industrial equipment or machines

- Liquid circulation system inside aerospace vehicles

- Water circulation system of aquariums or gardening equipment

In short, micro pumps are widely used in closed environments due to their small size and strong durability. As long as the enclosed environment can guarantee power supply and basic working conditions, the micro water pump can operate safely for a long time.
