The core power for drinking fountains-brushless DC pump

Everyone is quite familiar with drinking fountains, which are often used in daily life, but do you know why there is water? Some water pressure is very high, some are very small? You may not be able to answer these questions. Let me introduce a new friend to you. It often serves you, but you don’t know its name. It is called a DC pump or a water dispenser pump.

First of all, let me introduce you to the classification of drinking fountain pumps:

      1. Brush DC hot water circulation pump.

      2. Brushless DC hot water circulation pump (motor type)

      3. Brushless DC hot water circulation pump (magnetic drive isolation type)

Most drinking fountains use the third type, also known as brushless DC pumps. The following small series focuses on the third type of pumps.

      The brushless DC water pump adopts electronic component commutation, without using carbon brush commutation, and adopts high-performance wear-resistant ceramic shaft and ceramic bushing. The bushing is integrated with the magnet through injection molding to avoid wear, so the brushless DC magnetic force greatly improves the service life of the pump. The stator part and rotor part of the magnetically isolated water pump are completely isolated. The stator and circuit board parts are sealed with epoxy resin, 100% waterproof, the rotor part is made of permanent magnets, the pump body is made of environmentally friendly materials, low noise, small size and good performance. stable. Various required parameters can be adjusted by winding the stator, and can operate under a wider voltage.
