What Are The Kinds Of DC Micro Water Pumps？

According to the motor converter form can be divided into brush, no brush; such as DC with brush micro pump, DC with no brush micro pump.According to the working principle, it can be divided into diaphragm type, piston type, magnetic drive type, gear type and so on. In practice, a certain type of pump is often combined with the above several categories. For example, "DC brush micro diaphragm pump", "DC brushless micro magnetic pump" and so on. According to whether into the water can be divided into submersible pump and non-submersible pump, such as DC micro submersible pump, DC micro self-priming DC water pump.

When the pump is working, the coil and the commutator rotate, and the magnetic steel and the carbon brush do not turn. The alternating change of the coil current direction is completed by the commutator and the brush with the rotation of the motor. Because a power rotor began to rotate, will wear the carbon brush, these two forms of low-grade products, generally run a few hundreds of hours on the carbon brush, there will be failure. But the cost is also lower and much higher. Advantages include large torque (force), the same size of the brush motor and brushless motor, the brush pressure (head) is much larger than the brushless. The flow of the brushed motor can be done much more than the brushless motor. Disadvantages include a carbon brush has a certain life, cannot reach tens of thousands of hours like a brushless motor life; even with some difference. However, it can be used for non-continuous 24-hour operation occasions. The cost is higher; and cheap low grade brush pump life is shorter, only a few hundred hours. The liquid shall not contain particles and can not contain oil.

The motor brushless DC water pump is composed of brushless DC motor and impeller. The shaft of the motor is connected with the impeller, and there is a gap between the stator and rotor of the pump. After the use time, the water will penetrate into the motor, increasing the possibility of the motor burning out. Advantages include standardized brushless DC motors (such as brushless motors on ordinary fans or DVD). Disadvantages include the inability to apply to loads changing in size and direction (similar to tamping machines on construction sites, where industrial applications have high requirements for motors). Class is not high, easy to produce failure.

The brushless DC magnetic water pump adopts electronic component change, no need to use carbon brush change, using high performance wear-resistant ceramic shaft and ceramic shaft sleeve, shaft sleeve through injection molding and magnet into the whole to avoid wear, so the life of the brushless DC magnetic water pump is greatly enhanced. The stator part of the magnetic isolation pump is completely isolated from the rotor part, the stator and circuit board part are sealed with epoxy resin, waterproof, the rotor part adopts permanent magnet magnet, the pump body is made of environmentally friendly materials, with low noise, small volume and stable performance. Various required parameters can be adjusted by winding of the stator and can run with wide voltage. The advantages are long life, low noise up to 35dB below, can be used for hot water circulation. The stator and circuit board of the motor are sealed with epoxy resin and completely isolated from the rotor, which can be installed underwater and completely waterproof. The shaft of the pump adopts high-performance ceramic shaft, with high precision and good earthquake resistance. But the disadvantage is that the cost is high, so it is best not to use it above the liquid level for a long time. No self-priming ability, must be installed below the liquid level or diving.
