What is a bubble pump?

Bubble pump is a device used to increase fluid from one place to another, a higher place without mechanical energy. Instead, it uses thermal energy to supply this change in the position by increasing the lift of the fluid it moves. Sometimes it is referred to as an air-lift pump or steam pump. Its purpose is to increase the fluid from the lower tank to the higher. The fluid in the lower tank is usually heated, causing part of the liquid to change the phase to the forms of steam. This steam is floating more than a liquid form of fluid and rises up over the tube and carries some liquid up. In general, a one -way valve or other mechanism prevents flowing liquid back down to the tube when it cools.

A simple example is used by a bubble pump in a regular drip coffee machine. For many conventional coffee machines, the water is poured into the reservoir in the back and the coffee area is placed in the filtru at the top of the machine. To cook coffee, the water must be heated and then filtered through the coffee above it. In order to happen, the water must be raised somehow over the land so that it can drip it down. To accomplish this task, a bubble pump with a supply at the bottom of the water reservoir and its outlet above the land is used.

While many pumps use mechanical means to move the liquid, the bubble pump is driven only by thermal energy. As a result, its construction is very simple with several movable components. This provides benefits in terms of reliability and cost in many applications. However, these pumps are not usually suitable for use in high -pressure applications.

The gravitational force pulling downwards acts to face the ascending buoyancy of the liquid. The friction between the pumped liquid and the inner wall of the tube also resists its movement up. The effective design of the bubble pump must take into account variables such as friction between liquidAnd the tube, length and diameter of the tube, etc. The correct design is necessary to ensure that the forces against the movement of the fluid does not overcome the upper tank.

Bubble pumps are used in many applications, from very simple to highly technical. For example, aquaculture equipment and hatchery often use bubble pumps in their operations. Some solar water heaters use the heated liquid they contain, using a bubble pump to circulate it with a system. Bubble pump is also a key part of the cooling cycle known as the Einstein cycle.
