  • How Much Characteristic Of DC Humidifier Water Pump Do You Know?

    DC pumps are machines that transport or pressurize liquids. When the pump works, the coil and commutator rotate, the magnetic steel and carbon brush do not rotate, and the alternating change of the coil current direction is accomplished by the commutator and brush which rotate with the motor. Cha...

  • Cautions for Selection of DC Brushless DC Motor

    Brushless DC (BLDC) motors can be imagined as the opposite of brushless DC motors, in which permanent magnetism is on the rotor and winding is on the stator. Therefore, the motor has no brush and commutator, eliminating the disadvantage associated with spark generation of brush DC motor. The moto...

  • Fault analysis of cold and warm mattress water pump

    1.  The axis of the magnetic pump is broken. CQB type magnetic pump shaft is made of 99% alumina ceramics. The main reason for the fracture of the pump shaft is that the shaft is twisted because the pump runs empty and the bearing is grinded dry. When the pump is dismantled for inspection, it can...

  • How the pump works

    Let me talk about how the centrifugal pump works today. Before the pump starts, the pump and the inlet pipe are filled with water. After the pump is running, under the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller flow channel is pushed to the p...
