features of magnetic pumps
the advantages of magnetic pump with mechanical seal or packing of centrifugal pumps compared to Magnetic pump has the following advantages.
1. Shaft seal into enclosed by the moving static seal, completely avoid media leaks.
2. No separate lubrication and cooling water, reducing energy consumption.
3. Become synchronized by the coupling transmission drag, there is no contact and friction. Power consumption, high efficiency, and has a damping effect, reducing the impact of motor vibration on pumps and pump cavitation effects of vibration on the motor.
4. Overload, the inner and outer magnetic rotor relative slip of the motor, the pump has a protective effect.
four, running notes
1. To prevent particles from entering
(1) does not allow any ferromagnetic impurities, particles enter the magnetic clutch and bearing friction . (2) transport and crystallization or precipitation of the media time after washing (after the pump stops pouring water to the pump chamber, run a clean emissions after 1min) to protect the bearing life. (3) transport media containing solid particles should be filtered at the pump flow tube entrance.
2. To prevent demagnetization
(1) design of the magnetic moment is not too small. (2) should be run under the specified conditions of temperature, medium temperature exceeded is prohibited. Magnetic pump sets in the outer surface of the installation of isolation platinum resistance temperature sensor detects the temperature rise of the annulus region, so that the temperature gauge when an alarm or shutdown.
3. To prevent dry friction
(1) non-idling. (2) non-media taking the time. (3) In the case of discharge valve closed, pump continuous running time of no more than 2min, to prevent overheating and failure of magnetic clutch
