DC water pump

The DC water pump is a machine for conveying or pressurizing liquid. When the water pump works, the coil and commutator rotate, the magnetic steel and carbon brush do not rotate, and the alternating change of coil current direction is completed with the commutator and brush of the motor. The DC water pump adopts the water pump powered by DC power supply, and the commonly used voltages are 3V, 6V, 12V, 24V, 36V, 48V, etc,DC water pumps are divided into: brushless DC water pump and brushless DC water pump.

DC water pumps are widely used in new energy vehicles, intelligent toilets, water heaters, chillers, water heating mattresses, air conditioning drainage, coffee machines, humidifiers, washing machines and other household appliances.

The annual production capacity is more than 5 million sets of water pumps and it is one of the largest manufacturer of BLDC water pump in China. It won many honorable titles such as High-tech Enterprise, Multiplication Enterprise etc.

Working principle of DC water pump？

The working principle of DC water pump is that after the water pump is turned on, the impeller rotates at a high speed in the pump body (the pump body should be filled with liquid before the water pump is turned on). The liquid in the pump body rotates with the impeller. Under the action of centrifugal force, the liquid is thrown out by the impeller at the outlet, and 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 flows into the tank under the action of atmospheric pressure. The volume of the diffusion chamber of the pump body is fixed. With the increase of the thrown liquid, the pressure also increases gradually, and finally 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.

Working Principle of Brushless DC water pump?

Brushless DC water pump is a kind of permanent magnet synchronous motor, but not a real DC motor. Brushless DC water pump does not use mechanical brush device, adopts square wave self-control permanent magnet synchronous motor, replaces carbon brush commutator with Hall sensor, and takes neodymium iron boron as permanent magnet material of rotor. It has great advantages over general traditional DC motor in performance, and is the most ideal energy-saving brushless DC water pump today.

Characteristics of DC brushless water pump

1. Long service life, no maintenance, small size, high efficiency, low power consumption, strong anti-interference ability and stable operation.

2. No carbon brush, no pollution, electronic commutation, long service life.

3. The stator and circuit board of the motor are sealed with epoxy resin and completely isolated from the rotor, which solves the leakage problem caused by long-term diving of the motor DC water pump. It can be installed underwater and completely waterproof.

4. The parameters of the water pump can be adjusted according to the customer's requirements. The 24V water pump can adjust the lift of 2m or 7m. The volume remains unchanged and can operate under wide voltage.

5. The axis of the water pump adopts high-performance ceramic shaft (stainless steel shaft can be selected to reduce the cost), with high precision and good wear resistance. Due to the precise cooperation between the high-precision shaft sleeve and the ceramic shaft (other materials can be changed to reduce the cost), the noise is low, and the noise with lower power can even reach below 25 dB.

6. The three-phase non hall program driven DC water pump in the water pump series can realize PWM speed regulation, analog signal (0 ~ 5V) speed regulation and potentiometer VR manual speed regulation. In this way, the flow and head can be adjusted and the music fountain can be customized.

The three-phase DC water pump in the water pump is soft start, no impact, low starting power consumption, the circuit board is completely separated from the pump body, there are no electronic components in the pump body, the pump body is made of high-temperature resistant materials, and the water pump can be used in 100 ℃ water temperature for a long time. It has impeller rotor stuck protection, reverse connection protection, overload protection and overcurrent protection.

8. The water pump has abundant interfaces, including 4-point threads, 2-point threads, in and out 8mm, 10mm, 22mm, 27mm, etc., which can also be customized according to customer requirements

9. If the pump head needs to be increased, the pump can also be connected in series, and the head can be doubled.

10. Amphibious (for external use, the installation position is lower than the liquid level)

11. The water pump and its associated control system can be customized according to user requirements.
