1. Micro AC water pump:

佰富彩The commutation of the AC water pump is changed by the frequency of 50Hz of the mains power. Its speed is very low. There is no electronic component in the AC water pump, which can withstand high temperature. The volume and power of the same head AC water pump are 5-10 times of that of the DC brushless water pump.

Advantages: low price, more manufacturers

2. Brush DC water pump:

When the water pump works, the coil and the commutator rotate, the magnet steel and the carbon brush do not rotate, and the alternating change of the coil current direction is completed with the commutator and the brush that the motor rotates. As long as the motor rotates the carbon brush, it will produce wear. When the computer water pump runs to a certain time, the wear clearance of the carbon brush becomes larger, and the sound will also increase. After several hundred hours of continuous operation, the carbon brush cannot be replaced Yes, yes.

Advantages: low price.

3. Brushless DC water pump:

The motor type brushless DC water pump is composed of the brushless DC motor and the impeller. The shaft of the motor is connected with the impeller. There is a gap between the stator and the rotor of the water pump. The water will penetrate into the motor after a long time of use, which increases the possibility of the motor burning out.

佰富彩Advantages: BLDCM has been standardized and produced in large quantities by specialized manufacturers, with low cost and high efficiency.

佰富彩4. Brushless DC magnetic drive water pump:

佰富彩The brush free DC water pump adopts electronic component reversing instead of carbon brush reversing. It adopts high-performance wear-resistant ceramic shaft and ceramic shaft sleeve. The shaft sleeve is integrally connected with magnet through injection molding, so the service life of the brush free DC magnetic water pump is greatly enhanced. The stator part and the rotor part of the magnetic isolation water pump are completely isolated, the stator and the circuit board part are filled with epoxy resin, 100% waterproof, the rotor part is made of permanent magnet, and the pump body is made of environmental protection materials, with low noise, small volume and stable performance. It can adjust all kinds of parameters by winding the stator, and can operate at wide voltage.

佰富彩Advantages: long service life, low noise up to 35dB, can be used for hot water circulation. The stator and circuit board of the motor are filled with epoxy resin and completely isolated from the rotor, which can be installed underwater and completely waterproof. The axis of the water pump is made of high-performance ceramic shaft, with high precision and good seismic resistance.
