Brushless DC Pump (magnetic isolation of new pumps) magnetic pump is an advantage to achieve non-contact torque transmission and thus to replace the static seal dynamic seal, the pump reaches a complete solution to the "run, run, drip, leak" through magnetic drive problem, eliminating the refining and chemical industry, flammable, explosive, toxic, harmful media through the pump seal leak security risks, effectively ensuring the health and safety of workers in the production. Compared with the brushless DC motor pumps, magnetic pump has the following advantages: 1. Shaft by a dynamic seal into closed-static seal, completely avoid media leaks. You can amphibious, and completely waterproof. 2. No separate lubrication and cooling water, reducing energy consumption. 3. Low power consumption, high efficiency, and has a damping effect, reducing the impact on the motor when the cavitation vibration motor vibration of the pump and the pump effect occurs. 4. Overload of the rotor shaft in the ceramic slip of the motor, the pump has a protective effect 5. Brushless DC water pump with a commutation electronic components, without the use of carbon brush commutation, high-performance precision steel shaft and wear bushings, shaft sets by injection molding integrally connected with the magnet thus avoiding wear and tear, and therefore magnetic brushless DC pumps of life is greatly enhanced. Stator portion and the rotor portion of isolated magnetic pump completely isolated, the stator and the circuit board part epoxy potting, 100% waterproof, the permanent magnet rotor part, the pump body with environmentally friendly materials, low noise, small size, performance stable. You can adjust various parameters required by the stator windings can be wide-voltage operation. Advantages: long life, low noise up to 35dB or less, can be used for hot water circulation. Part of the motor stator and the circuit board using epoxy potting and the rotor is completely isolated, can be installed under water and completely waterproof, water pump axis high-performance precision steel shaft, high-precision, high shock resistance. Corrosion, acid, high temperature. Brushless DC water pump (magnetic pump) Principle of Brushless DC magnetic drive pump impeller magnet and injection-molded integrally composed of the motor rotor, the rotor has a direct injection molding intermediate sleeve, fixed in the housing by means of a high-performance ceramic shaft, motor The stator and the circuit board part epoxy potting in the pump body, a layer of thin-walled isolation between the stator and the rotor, without accompanied by traditional mechanical seal, so it is completely sealed. Motor torque through the coil is energized silicon steel (stator) on the permanent magnet generates a magnetic field drive (rotor) work operation. Magnet be n (n even) level magnetizing the magnet portion coupled to each other to form a complete magnetic systems. When the poles of the stator coil and magnet poles in different poles relative to that shift angle Φ between two poles = 0, then the lowest magnetic energy magnetic system; when the pole is rotated relative to the same pole, the two poles between displacement angle Φ = 2π / n, this time the maximum magnetic energy magnetic system. After the removal of the external force, due to the magnetic system poles repel each other, the magnetic force of the magnet will return to the lowest magnetic energy state. So the magnet in motion, driven magnetic rotor. Brushless DC pumps by electronically commutated, without the use of brushes, magnet rotor and stator magnetic silicon steel has a multi-level, when the magnet rotor relative to the stator rotation angle automatically changes the magnetic pole direction after the rotor always maintain the same level of exclusion, Brushless DC magnetic isolation so that the pump has higher speed and efficiency. Magnetic isolation pump stator and the rotor is completely isolated, completely avoid the traditional type brushless DC motor pumps presence of liquid leaks. And it can be completely and totally waterproof diving use, effectively improve the life and performance of the pump.
