What’s the Working Principle of Electric Air Pumps
The Working Principle of Electric Air Pumps
An electric air pump is a pump that uses electricity as a power source and uses the input power to pump air. The electrical energy is usually supplied by a DC power supply or a battery.
Its working principle of electric air pumps: Every electric air pump will be designed with impeller blades, diaphragms, or vanes. When energized, the electrical energy will be converted into the mechanical energy of the impeller blades to rotate continuously. With the continuous rotation of the impeller blades, the air in the pump will be evacuated, forming a vacuum inside the pump. At this time, because the internal pressure of the pump is lower than the external pressure of the pump, the air in the atmosphere will be squeezed into the pump and filled continuously.
The electric air pump is used for weddings, large banquets, birthday parties, aquariums, ponds, and vacuum cleaner inflation, etc, usually. They operate in a relatively low-pressure environment. The airflow is running in the electric air pump continuously. An electric air pump is a free-flowing pump with minimal or no backpressure.
Take an Usage Example——Inflating Balloons
In daily life, it is very convenient for us to use electric air pumps on many occasions. Electrical air pumps are suitable for inflating balloons in wedding venues, and many large-scale event site layouts.
To inflate the balloon, what we need to do at the first step is to connect the cone-shaped nozzle to the electric pump, which you can find in any sporting goods store. When turning on the electric pump, you need to insert the cone-shaped nozzle into the balloon’s opening.
Second, when the balloon is inflating, fix the balloon on the tip of the nozzle.
Finally, after inflating the balloon fully, squeeze its opening, remove it from the nozzle and tie it, and turn off the switch.
What Occasions Can the Electric Air Pumps be Used?
First, they are mainly used to inflate vehicle tires. It is recommended that people who often travel by car and drive long distances had better carry an inflator to avoid serious tire wear, even occurring traffic accidents due to insufficient air in the tire. Using air pumps in daily life reduces people save time, money, and labor consumption. Thus, most salespersons travel with electric pumps when they go on business trips.
Second, vacuum cleaners——They clean our floors by trapping dust particles in the chamber.
Third, the purpose of aeration——The air pump is used in fish tanks and ponds to inflate the water with the help of air stones to increase the oxygen in the water, to prevent the fish from suffocating due to lack of oxygen.
Fourth, they can be used as gas compressors in powering the air horn and pneumatic tools also.
Fifth, they are widely used for kayaks, kids’ toys, and sports balls for fun activities and during vacation times.
Sixth, Shoe pumps-Reebok has made a small pump in their shoes so that they can provide a cushioning effect. While people run and walk, it will have a certain effect on cushioning, to reduce wear and damage to the feet. They are used to improve the comfort of customers wearing shoes while walking.
How to Select an Electric Air Pump?
When choosing an electric air pump, we have to consider a variety of factors, among which the main factors we need to consider are: operation mode, power requirements, nozzles, flow rates, and power cords.
Operation mode——When choosing an air pump, we should consider the use time, operation of the air pump, and its cost. There are two types of air pumps available for selection usually: manual operation and automatic operation. Manually operated pumps are generally much cheaper than automatically operated pumps, but a manual process is required. Automatically operated pumps can run without manual intervention but are expensive compared to manual pumps. Most importantly, the automatically operated pump can work for hours without manual operation continuously.
Power requirements——When using an electric air pump, we must consider whether the power of the air pump meets the applicable conditions according to the different environmental conditions. Portable electric air pumps are powered by batteries usually, and the rated voltage range is 12V or 24V generally. When choosing a battery-powered inflator, the battery must be appropriate, and battery life counts so that it can last long enough to complete the entire inflation process.
Nozzles——Generally, the electric air pumps we buy are equipped with replaceable hoses, which can be interchanged with nozzles according to our usage. Some electric air pumps may have fixed nozzles also, which cannot be replaced. Therefore, when selecting an electric air pump, we need to choose the right accessories for our operation.
Flow rates——According to different usage requirements, we need to choose an electric air pump with a suitable flow rate for our operation. For operations that need to be completed quickly, such as inflating tires, blowing parachute balloons, inflating arches for large-scale events, etc., we need to select a high-flow electric air pump to complete the operation. Flow rate we can measure in “gallons per minute” (GPM).
Power cords——For different use occasions and different voltages and powers, we should select different lengths, thicknesses, and connection types’ power cords for the electric air pump are different. For example, we usually adopt a very long power cord to inflate rafters in a swimming pool and inflate arches for large-scale event scenes.
The factors that we need to consider when choosing an electric air pump are much more than that. But on the whole, when we choose a suitable electric air pump, the most important thing is to learn to choose suitable electric air pumps of different powers, different flow rates, and different sizes for various applications, so as to save time and cost and improve Work efficiency is very important.
The Benefits of Electric Air Pump over a Manual Pump
Firstly, some electric air pumps are heavier than manual air pumps, increasing the energy and battery costs of certain electric vehicles, however, the overwhelming advantage of electric air pumps is that they can work for a long time without stopping and can complete tasks quickly, which manual air pumps can not finish in general.
Secondly, manual air pumps cannot work as efficiently as electric air pumps. Most electric inflator pumps will have an automatic pressure gauge, which can stop the inflation when the item that needs to inflate is finished inflate. In addition, the electric air pump can run continuously for several hours, saving money, time, and energy.
Thirdly, most electric air pumps have different extensions to connect to various nozzles and threads. However, most specially designed manual air pumps only have 1 or 2 nozzles to link. In addition, electric air pumps are also very sturdy and easy to repair, while repairing manual air pumps usually need the help of your hands and feet.
Finally, people mainly use the manual air pump for insulation applications. Its price will be lower, but the use occasions are relatively narrow. Thus, it usually has lower satisfaction. Advanced electric air pumps are generally suitable for various occasions, and one unit can achieve multiple purposes.
