Hot water pump shaft sealing ring leakage has a big impact on the flow of Yang Cheng?
2 brushless motor DC water pump: brushless DC motor pump is the use of Brushless DC motor coupled with the impeller after the composition. The shaft of the motor is connected with the impeller, and there is a gap between the stator and the rotor of the water pump. After a long time use, the water will permeate into the motor and increaseHot water circulating pump (2 sheets)Possibility of motor burn out.
1, DC water pump: the pump when the rotating magnet and coil and commutator, brush does not turn, change the current direction of the coil with the motor rotating commutator and brush to complete, as long as the rotation of the motor will produce carbon brush wear, computer pump operation to a certain time, wear big gap, there will be along with the increase of hundreds of hours of continuous operation after the brush can not play the role of reversing.
3, brushless DC magnetic drive pump adopts electronic components: non reversing brushless DC pump, without the use of brush commutation, using the high performance ceramic shaft and ceramic sleeve, sleeve whole will avoid wear and magnets by injection. Therefore, brushless DC magnetic type water pump life greatly enhanced. Complete isolation of the stator part and the rotor part of isolated magnetic pump, stator and circuit board using epoxy resin potting, 100% waterproof, some with permanent magnet rotor and pump body with environmentally friendly materials, low noise, small volume, stable performance. The required parameters can be adjusted by the winding of the stator and can be operated at wide voltage.Advantages: long life, low noise, less than 35dB, can be used in hot water circulation. The stator and the circuit board of the motor are encapsulated by epoxy resin and completely separated from the rotor. It can be installed underwater and completely waterproof. The high strength ceramic shaft is adopted in the axis of the pump. The utility model has the advantages of high accuracy and good shock resistance.The traditional brush type brushless motor water pump and water pump, the structure is because the motor shaft core and rotor impeller are directly connected, using the shaft seal, work, shaft and seal is direct friction, very short life, its structure is doomed to be very difficult to wear, waterproof and waterproof; in order to improve of the shaft and the gasket between the more grease, this will also limit the industry limitations.
