Product details

The working principle of the brushless micro submersible pump in the humidifier mainly relies on its efficient and precise design. The following are the main steps and principles of its operation:

1. Drive and structure: The core part of the brushless mini submersible pump is formed by the magnet and the impeller being injection molded into one, forming the rotor of the motor. There is a directly injection molded sleeve inside the rotor, which is firmly mounted in the pump body through a high-performance ceramic shaft to ensure stable operation. The stator of the motor is closely connected to the circuit board part and is potted with epoxy resin glue to form a completely sealed structure without the need for a mechanical shaft seal.

2. Magnetic field and rotation: The torque of the motor comes from the magnetic field generated by the coil on the silicon steel sheet (stator) after power is supplied. This magnetic field drives the permanent magnet (rotor) to work and operate. By magnetizing the magnets in even levels, the magnetic system between the magnets forms a complete coupling, thereby ensuring the effective use of magnetic energy.

3. Water flow generation: When the magnetic poles are opposite (that is, the displacement angle is 0 or 2π/n), the magnetic energy reaches the lowest or highest level. This change in magnetic energy drives the magnet to move, which in turn drives the magnetic rotor to rotate continuously. As the rotor rotates, the impeller starts to work, sucking in and pressurizing the surrounding water, and then pushing it to the water outlet.

4. Humidification process: The pressurized water flows into the water tank or atomization part of the humidifier through the water outlet. In the atomization part, the water is further refined into tiny water droplets or water mist, and then blown into the air by a fan or natural wind, thereby increasing the humidity of the air.

5. Stability and efficiency: Due to the design of the brushless motor, the carbon brushes and commutators in the traditional motor are reduced, thereby reducing the possibility of wear and failure. This makes the micro brushless submersible pump have higher stability and longer service life. At the same time, its efficient magnetic field drive method also ensures higher energy utilization efficiency.

What is the role of a brushless dc submersible pump in a humidifier?

The main function of the brushless miniature submersible pump in the humidifier is to transport water from the inside of the water tank to the atomizer. Specifically, the micro brushless submersible pump uses the driving force of the brushless motor to effectively transport the water in the water tank to the atomizer part. The atomizer then atomizes the water sent by the water pump, converts it into fine water mist, and sprays it into the air through the atomizer nozzle to achieve the humidification effect.

In addition, the micro brushless submersible pump also has the characteristics of high efficiency and low energy consumption, which can improve the energy utilization efficiency of the humidifier and reduce operating costs.

At the same time, due to the use of brushless motors, the operating noise of this water pump is also relatively low, which helps to improve the user experience.

It is worth noting that since humidifiers are usually used in homes, offices, hospitals and other places, the safety, stability and durability of micro brushless submersible pumps are also very important. These characteristics can ensure that the humidifier can work stably and safely during long-term operation, providing users with a comfortable and healthy indoor environment.

How does a brushless electric submersible pump ensure the safety of a humidifier?

1. No sparks and no pollution: The micro brushless submersible pump adopts electronic commutation technology to avoid the sparks that may be generated by traditional brushed mechanical commutation, thereby reducing the risk of fire. At the same time, it will not produce pollutants, ensuring that the water mist released by the humidifier is clean and harmless, suitable for use in homes, offices and other places.

2. Low noise and low power consumption: The micro brushless submersible pump has low noise during operation and will not cause noise pollution. At the same time, the power consumption is relatively low, which is conducive to saving energy and reducing the cost of use.

3. Stable performance and long life: The brushless submersible pump has a longer service life and more stable performance because there is no problem of brush wear. This reduces the safety risks caused by equipment failure.

4. Perfect self-protection function: Many micro brushless submersible pumps are equipped with an automatic shutdown function. When the pump has abnormal conditions, such as overload, overheating, etc., it can stop working automatically to prevent accidents.

How does a brushless small submersible pump achieve self-protection function?

First of all, the intelligent control system is the key. The system can monitor the working status of the submersible pump in real time, including parameters such as current, voltage, and temperature. Once these parameters exceed the preset safety range, the control system will immediately trigger the protection mechanism. For example, when the temperature of the pump is too high, the thermistor will cut off the circuit in a short time, thereby avoiding equipment damage or safety accidents that may be caused by overheating.

Secondly, physical protection measures also play an important role. Some submersible pumps are equipped with stainless steel protective sleeves, which can effectively prevent physical damage to the pump body caused by the external environment. At the same time, the sealing design of the pump can also prevent water or other liquids from entering the interior of the pump, thereby protecting the circuit and motor from damage.

In addition, the brushless 12v dc submersible water pump also uses advanced brushless motor technology. This motor has no problem of brush wear, so it has a longer service life and more stable performance. This also reduces the safety risks caused by motor failure.

Finally, the micro brushless submersible pump usually also has an anti-dry-run function. When the pump is in a waterless state, the anti-dry-run function will automatically stop the pump from working, avoiding damage caused by the pump running in a waterless state.

How to calculate the capacity of a brushless mini submersible water pump?

1. Determine the required flow rate of the system: First, it is necessary to clarify the liquid flow rate required to be delivered by the submersible pump. This usually depends on the specific application scenario and process requirements. For example, when used in a humidifier, factors such as humidification area, ambient humidity, and humidification speed may need to be considered to determine the required flow rate.

2. Determine the output pressure: Secondly, it is necessary to determine the maximum output pressure that the submersible pump can withstand. This depends on the design and requirements of the pipeline system, as well as the performance parameters of the submersible pump itself.

3. Consider pipeline parameters: The inner diameter, length, number of elbows, and friction loss coefficient of the pipeline will affect the working efficiency and capacity of the pump. These parameters need to be considered in combination with actual conditions.

4. Consult the performance curve of the submersible pump: After determining the above parameters, it is necessary to consult the performance curve of the selected micro brushless submersible pump. By comparing the relationship between flow and pressure, the appropriate capacity that meets the needs can be found.
