How Does a USB Water Pump Work? (Working Principle)

USB water pump is a brushless dc pump with a working voltage of 5V DC, so it is also called 5V DC water pump. Its pump impeller rotates at high speed in the pump chamber (The pump chamber must be filled with liquid before turning on the pump). The liquid in the pump chamber rotates with the impeller. Under the action of centrifugal force, the liquid is thrown out by the impeller at the outlet. The speed of the thrown liquid gradually slows down in the diffusion chamber of the pump body. After the liquid is thrown out, a vacuum low-pressure area is formed at the center of the impeller. The liquid in the liquid pool flows into the water pump through the suction pipe under the action of the external atmospheric pressure. The volume of the diffusion chamber of the USB water pump body is fixed. As the amount of liquid thrown out increases, the pressure gradually increases, and finally it is discharged from the outlet of the water pump. In this way, the liquid is continuously sucked up from the liquid pool and then continuously discharged from the outlet of the water pump.

Advantages of USB Mini Water Pump

Do you often see USB mini electric water pump in many occasions and places in your daily life? I think so. Why do these electric water pumps often appear in your field of vision? Or why are these water pumps so popular? This is because it has many advantages. Let me take you to understand the many advantages of USB water pumps:

1. Low Noise and Low Energy Consumption

USB DC water pump uses chips and brushless DC driver boards to realize the pumping function. There is no electromagnetic interference and electromagnetic noise, so the noise is very low, the lowest can reach below 25dB. It can also run for a long time with low energy consumption, generally only 3~5W of power, almost no electricity cost, and is extremely energy-saving.

2. Long Life and Stable Performance

The USB DC brushless water pump uses electronic components for commutation, without the need for carbon brushes, which greatly increases its lifespan. The rotor part uses permanent magnets, and various required parameters can be adjusted through the winding of the stator, and it can operate at a wide voltage. The water pump body is made of environmentally friendly materials, with a small size and stable performance. It can work uninterruptedly for 24 hours for a long time.

3. Safe, Waterproof and Shock-Resistant

The stator and circuit board of the USB DC brushless water pump motor are encapsulated with epoxy resin and completely isolated from the rotor, which is safe and reliable. It can be installed underwater and is completely waterproof, with a waterproof rating of up to IP68. The axis of the water pump uses a high-performance ceramic shaft with high precision and good shock resistance.

4. Various Power Supply Forms

The working voltage of the USB water pump is DC 5V or 12V, and it can be directly powered by the computer USB port, mobile phone charger and power bank etc.

5. High Performance, Wide Application

The working flow rate of the USB water pump is about 1.8~3.5L/min of static flow rate, and the range of hourly flow rate that can be adjusted is about 50-200L/H, which is much higher than the performance of the same volume of AC water. This is the flow rate of clean water. This small pump is generally not suitable for working in water with too many impurities. If it is used as a circulating water pump in a fish tank, filter cotton needs to be installed. When the voltage is 5V, the head is generally 0.4m-1.8m. If used in a desktop fish tank or an ecological water flow ornament, one meter is generally enough. Therefore, USB water pumps are widely used in water transport, circulation applications.

6. No Maintenance Required

The USB DC water pump has a long service life, reliable performance, no wearing parts, a fixed stator, a rotating rotor, and a simple structure. When pump is working, the water is self-lubricated and no lubricating oil needs to be added, so the water pump does not require maintenance.

How to Choose a USB Water Pump？

First, determine the working voltage, current, head and flow rate, and caliber size. The maximum head of the water pump generally refers to the static head when the water is pumped to the maximum head without water flow. If you requires that the water flow rate be maintained after the water is pumped to a certain height, the head required when selecting the water pump must be higher than the specified pumping height.

This is determined by the supplier based on actual conditions. You can refer to the head flow curve. Determine the volume and shape requirements (threaded interface, inlet and outlet direction, caliber size, etc.) Determine the working environment (temperature, medium) Determine the functional requirements (time control, motion control, pressure control, flow control, speed regulation, etc.

What Kind of Power Supply can Power USB water pump?

As a mini water pump , USB pump can be powered by a variety of sources, including but not limited to mobile phone adapters (charging heads), computer USB ports, power banks, solar panels, and even car cigarette lighters. The wide selection of power supply methods is also the main reason why USB water pumps are so popular among users and can be quickly popularized.

Application of USB Water Pump

Due to the various power supply forms of USB water pumps and the small size that makes it portable, and widely used. It can be used in many scenes such as home, car, garden, and outdoor, and is very popular among users. Main uses are:

1. Used for circulating water pumping in fish tanks
2. Used for bottom filtration of water travel boxes
3. Used for indoor bonsai fountains
4. Used for flowing water crafts
5. Used for garden fountains

How to Use USB Water Pump？

When you buy a USB water pump, you may like it but don’t know how to use it. You are very cautious and dare not connect it to the power supply easily, for fear that it will be burned out by improper use. But don’t worry. VOVYO will teach you how to use the water pump and what you need to pay attention to before use. Following these steps and usage points, you can quickly get started. You no need to worry about damaging the water pump if you use it correctly. Let’s start using it together:

1.How to use

Take out the USB water pump and install the outlet pipe into the outlet position of the pump body, select a hose that matches the outlet pipe to connect it, and place the pump flat or sideways in a suitable position in the fish tank.

After installation, connect the matching power adapter and the water pump can work normally (if there is no water during the first use, please disconnect the power connection several times to exhaust the air in the water pump!)

2. Precautions

Before using a USB water pump, you need to pay attention to the following points:

Before using the water pump, you must first check whether the voltage marked on the nameplate of the pump is consistent with the actual voltage. If it does not match, please do not use it to prevent the water pump or power supply from burning out.
Before installation, please carefully check whether the water pump and the power adapter power cord are damaged. If so, please do not use it and contact customer service for replacement in time.

The inside of the water pump needs to be cleaned frequently to ensure that the water pump can work normally.

The water pump must be used submersible, and the pump body cannot be left idling for a long time to avoid burning out the water pump.
When taking out the water pump, please do not pull the power cord at will to avoid poor contact of the power cord.

USB DC Water Pump Usage Precautions

Precautions for using USB DC water pumps: prevent particles from entering, and do not allow ferromagnetic impurities and particles to enter the magnetic transmission and bearing friction pairs; Flush in time after conveying media that are easy to crystallize or precipitate (fill the pump cavity with clean water after stopping the pump, and drain it clean after running for 1 minute) to ensure the service life of the sliding bearing; When conveying media containing solid particles, filter it at the entrance of the pump flow pipe.

To prevent demagnetization, we should operate the pump under the specified temperature conditions, and it is strictly forbidden to exceed the medium temperature. You can install a platinum resistance temperature sensor on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annular gap area, so as to alarm or shut down when the temperature exceeds the limit. Prevent dry friction (some waterless protection can be ignored) and minimize idling time.

Install the pump below the liquid level. As USB water pump is a centrifugal water pump and cannot automatically exhaust air, you should submerge or installe it below the liquid level when in use. Reduce idling time (some waterless protection can be ignored). The water pump should not be idling as much as possible. Since there is no medium lubrication during idling, it is easy to wear. Do not exceed the rated voltage. The pump must be used at the rated voltage. Any overpressure or other functional requirements must be stated in advance.
