What is a brushless DC water pump?

Release time:2020-02-21 14:36:19  Browse times:

Definition of brush free DC water pump: it is a machine that uses DC 4.5v-24v to drive the brush free motor to operate, and the rotation of the brush free motor drives the impeller to rotate, so as to increase the liquid pressure to transmit the liquid.

The brush free DC water pump can be divided into: the brush free motor DC water pump and the brush free DC magnetic drive water pump.

1、 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.

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

2、 Brushless DC magnetic drive water pump:

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.

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.
