Principle of DC water pump and application of DC water pump in garden waterscape and fish pond

The brushless DC water pump uses electronic components for commutation, without using carbon brushes for commutation. It uses high-performance wear-resistant ceramic shafts and ceramic bushings. The bushings are integrated with the magnets through injection molding to avoid wear and tear. Therefore, the brushless DC magnetic force The service life of the water pump has been greatly enhanced. The stator part and rotor part of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are potted with epoxy resin and are 100% waterproof. The rotor part uses permanent magnets. The water pump body is made of environmentally friendly materials. It has low noise, small size and high performance. Stablize. Various required parameters can be adjusted through the winding of the stator and can operate at a wide voltage range.

The DC water pump has a long life and a low noise of less than 35dB, and can be used for hot water circulation. The motor itself of the brushless DC water pump motor is the electromechanical energy conversion part. In addition to the motor armature and permanent magnet parts, it also has sensors (there are also three-phase sensorless ones). The motor itself is the core of the brushless DC motor which is energized. Electronic commutation overcomes the problems of brushed DC motors. Brushless DC motors have the characteristics of brushed DC motors and are also frequency changing devices, so they are also called DC variable frequency water pumps. The international common name is BLDC. Brushless DC motors The operating efficiency, low-speed torque, speed accuracy, etc. are better than any inverter with any control technology. It is very important to use DC water pumps to realize water circulation in the design of garden landscape water features. Water landscape has become an indispensable link in water landscape design. It has the characteristics of flexibility, cleverness, etc. It can play the role of organizing space and coordinating changes in waterscape. It can also clarify the tour route and give people a clear sense of direction.
