This is a very interesting question. The water pump industry covers a wide range of fields, including environmental protection, medical treatment, water treatment, and instrumentation. The voltage range involved includes both DC and AC voltages. Common DC voltages include 1.5V, 3V, 6V, 12V, and 24V, while common AC voltages include 220V and 380V (for industrial use). It's no exaggeration to say that wherever there's water, there's a micro water pump!
The same is true for micropumps, but years of experience have taught us that no single micropump can meet all requirements; each type has its advantages and disadvantages. For example, micro magnetic pumps are commonly used for water circulation and can operate continuously for long periods of time, but they lack self-priming capabilities. Micro high-pressure diaphragm pumps are commonly used for high-pressure cleaning and spray cooling. However, if left unattended and without water, they may run idle and burn out. Micro self-priming pumps are often used for on-site sampling and water quality analysis. High-temperature water cannot be pumped using a micro peristaltic pump. While the flow rate can be very low, the pulsation is very strong, potentially causing significant pulse noise interference, leading to failure or unexplained malfunction of the precision control circuits and LCD screens associated with the pump.
As for the question above: Which is better, a low-pressure micro pump or a high-pressure micropump? Let's use the water-heating mattress industry as an example (because this industry currently uses pumps with two voltages):
First, let's understand the concepts of low-pressure and high-pressure water pumps. In simple terms:
Low-pressure water pumps generally refer to DC power supplies, such as 12V or 24V DC.
High-pressure water pumps generally refer to AC power supplies, such as 220V or 380V DC.
Water-heating mattresses, also known as water-heating blankets, water-heating electric blankets, and constant-temperature water-heating blankets, consist of a water-heating mattress and a water reservoir. Water is heated or cooled in the reservoir and then pumped to the water-heating mattress or water-heating kang to warm or cool the body. The heating range of water-heated mattresses is generally within 70°C, but some customers require a water pump that can withstand water temperatures up to 100°C. Mattresses are made of polyvinyl chloride (PVC) and silicone tubing. PVC is relatively inexpensive, so many customers choose it to reduce costs. However, PVC cushions have high resistance, so a high-lift pump is required, while silicone tubing is relatively expensive. High-end customers often choose cushions made of this material, and pumps with this high lift are less necessary.
The mattress industry initially used 220V AC water pumps. However, as living standards improve, safety, noise, and performance requirements increase, making 220V pumps difficult to meet. Subsequently, DC micropumps (6V, 12V, and 24V) were developed, offering improved performance in various areas. Why are Shenzhen Pincheng DC micro pumps preferred? Because they offer the following advantages:
1. Long life, maintenance-free, compact size, high efficiency, and low power consumption.
2. The motor's stator and circuit board are encapsulated with epoxy resin, completely isolating it from the rotor. This eliminates the problem of long-term submersible leakage in motor-type DC water pumps, making them suitable for underwater installation and completely waterproof.
3. A variety of parameters can be achieved using the same voltage. For example, a 24V pump can achieve a head of 2m or 7m. The pump can operate across a wide range of voltages; for example, a 24V pump can operate at voltages lower than 24V.
4. The pump shaft utilizes a high-performance ceramic shaft, offering high precision and excellent wear resistance. Thanks to the combination of the shaft sleeve and ceramic shaft, noise levels are below 35dB, and even lower power levels can reach below 30dB, achieving near-silence.
5. The three-phase, Hall-less, programmable DC micro water pump features PWM speed regulation, analog signal input, and potentiometer manual speed control, enabling adjustable flow and head, allowing for customized musical fountains.
6. The three-phase DC water pump features impeller and rotor stall protection, reverse polarity protection, overload protection, and overcurrent protection.
7. The three-phase programmable DC water pump features a soft start, no shock, and low startup power consumption.
8. The circuit board of the three-phase programmable DC pump is completely separate from the pump body, eliminating any internal components. The pump body is made of high-temperature-resistant material, enabling long-term operation in boiling water.
9. The three-phase DC programmable water pump is our company's unique and innovative product, featuring high technological content, a high degree of intelligence, and convenient control.
10. The pump can be configured with four or six threads to meet specific customer needs.
11. The versatile design allows for submersible use or outdoor installation (below the liquid surface).
12. The pump can be customized to meet customer requirements.
In summary, based on the above analysis, most DC micropumps (12V and 24V) in the water-heated mattress industry will replace 220V AC micropumps. This is just a case study. As mentioned at the beginning: no single micropump meets all requirements; each pump has its advantages and disadvantages. DC pumps are superior to AC pumps in some areas, and AC pumps are superior to DC pumps in others. Only a pump that meets the needs of industry development is a good pump.
