Application of small water pump in water heater industry

Published:2021-08-10

As a national bathing artifact, water heaters have been developed for more than ten years, and technology has continued to advance. Innovative products such as anti-electric walls, anti-switches, 3D rapid heating, and frequency conversion capacity have appeared in the industry. Water heaters are safe, energy-saving, heating speed, Continuous improvement in water output and other aspects, and continuous growth in market sales over the years. With the improvement of people's living standards in recent years, people's demand for water consumption is increasing. The selling volume of electric water heaters has increased from 40 liters in 2000 to about 60 liters today, and has been maintaining a continuous upward trend. . One of the key elements in such a national bathing device is the water heater pump. Regardless of its small size, it has a great effect, affecting the amount of water and the strength of the water pressure, etc. Let the editor take you to understand the small water pump in the water heater. Applications.

water heater pump

The small water pump for solar water heater shower, the professional name is brushless DC circulating water pump. It uses the principle of permanent magnet brushless DC motor, adds an impeller to its rotor, and is designed as a cavity for liquid centrifugal movement on the shell structure. The structure, because there is no carbon brush friction, there will be no sparks; high efficiency, low power consumption, longer life than brush motors, and low noise.


Brushless DC circulating water pump for solar water heater shower, low starting current, high pump efficiency, simple operation, stable and reliable operation, can be directly used with solar energy, long service life (more than 20,000 hours), low noise (about 40dB), brushless Pollution, absolutely environmental protection, safety and health, environmental protection and energy saving (because brushless is electronically controlled commutation, no sparks, no carbon brush dust pollution), no interference, smooth speed regulation (three-phase brushless water pump) 6. Excellent design structure : The water pump head is connected with the motor rotor cavity, and the motor rotor cavity is absolutely isolated from the motor stator part, so that it is completely waterproof and leakproof and the motor water pump has high efficiency.


The characteristics of Shenpeng electronic water heater pump:


1. Efficient ECM brushless motor, long life, no maintenance, small size, high efficiency, low power consumption

2. Excellent design structure: the water pump head is connected to the motor rotor cavity, and the motor rotor cavity is absolutely isolated from the motor stator part, so that it is completely waterproof and leak-proof and the motor water pump is highly efficient

3. Safety and health, environmental protection and energy saving (because brushless is electronically controlled commutation, no sparks are generated, no carbon brush dust pollution).

4. Can be connected for a long time and work for 24 hours

5. Waterproof grade: IP68

6. The axis of the water heater pump adopts a high-performance ceramic shaft, which has high precision and good wear resistance. Because the water pump adopts a precise fit between the shaft sleeve and the ceramic shaft, the noise is lower than 32 decibels, and the lower power can even reach below 32 decibels. Almost a silent effect.

7. The three-phase DC water pump in the water pump can realize PWM speed regulation, analog signal input speed regulation, and potentiometer manual speed regulation, so that the flow rate and head can be adjusted, and the music fountain can be customized.

8. Three-phase brushless water pump, with impeller rotor jam protection, reverse connection protection, overload protection, and overcurrent protection.

9. The three-phase brushless water pump is controlled as a soft start, no impact, and low start-up power consumption.

10. Multifunctional design, can be used in diving or placed outside (installation position is lower than the liquid level)

11. The pump can be customized according to user requirements and designed according to customer requirements. Remarks: Maximum liquid temperature -40 to 105 degrees (according to user requirements) Power cord length: According to user requirements, the brushless DC pump has long life, low energy consumption and high efficiency , No spark, no vibration, low noise, stable speed, reliable operation and so on.
