overview
Self-priming magnetic drive pump (hereinafter referred to as self-priming magnetic pump), the pump with static seal instead of dynamic seal, so that the pump flow parts in a sealed state, to solve the other pump mechanical seal can not avoid easy to run, easy to drop, easy to leak the ills, the pump body and flow parts of the material are made of corrosion resistant stainless steel, steel marble ceramics, PTFE graphite and other materials. It has the function of magnetic drive pump, and self-priming in the body, without the need of bottom valve and irrigation water, self-priming height of 4 meters. It has the advantages of compact structure, beautiful appearance, small size, low noise, reliable operation, easy use and maintenance, and can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research and other units pumping acid, alkali, oil and rare and precious liquid, venom, volatile liquid, as well as circulating water equipment, suitable for leakage, flammable, explosive liquid pumping.
features
Self-priming magnetic drive pump is based on the self-priming pump using magnetic coupling to achieve torque contact-free transmission, is no shaft seal, full seal, no leakage, corrosion resistance, pollution-free new environmental protection magnetic pump.
1. Self-priming magnetic pump is a non-leakage fluid transport machine without dynamic seal. To describe the centrifugal pump in the vane pump, the pump body, barrier sleeve and connecting parts are generally composed of a closed sealing chamber that can accept pressure. There is a rotating permanent magnet field outside the sealed cavity, and through the effect of magnetic field, the magnetic rotor components inside the femoral sealing cavity rotate synchronously, and the rotor components inside the sealed cavity femoral impeller to complete the work on the fluid. Because there is no dynamic seal in the closed sealing chamber composed of the stator components, and the rotating shaft of the femoral impeller does not penetrate the closed sealing chamber. Then ensure the magnetic pump zero leakage, pollution-free.
2. The structure design is composed of a motor, magnetic coupler and centrifugal pump, its main feature is the use of magnetic coupler to transfer power, when the motor femoral dynamic magnetic coupler external magnetic rotor rotation, the magnetic force line through the gap and barrier sleeve - acting on the internal magnetic rotor, so that the pump rotor and the motor synchronous rotation, no mechanical touch to transfer torque, the power input end of the pump shaft, Because the liquid is closed in the stopped barrier sleeve, there is no dynamic seal, so the fluid is in the sealed cavity, there is no leakage gap, therefore, the whole process of closing is completed, and the skill needs of no leakage are reached.
3. The technical design used follows the advantages and characteristics of the original self-priming pump in hydraulics. It cancels the traditional mechanical seal device, changes the rigid connection between the motor and the pump to a contactless flexible connection, and fundamentally eliminates the shaft seal leakage.
