Pump industry suppliers to tell you: import for magnetic pump suction should be how to solve

magnetic drive pump magnetic pump, and shielding pump, only static seal no dynamic sealing structure, so during conveying fluid leak-off, used in the petrochemical system conveying inflammable, explosive, volatile, toxic, such as corrosion and precious liquids.

the water pump body structure or centrifugal pump. But using magnetic drive transmission principle. Through the coupling of the motor and outer magnetic steel together. Within the impeller and magnet steel together. Between the inner and outer magnetic steel is equipped with fully sealed isolation cover, the inner and outer magnetic steel completely separated, the magnetic steel in the medium.

once the operating temperature is higher than in the operation of the magnetic pump magnet steel allowable temperature, the demagnetization effect will occur. Domestic magnetic pump generally use temperature for 1 ℃. Magnetic pump transmission medium is not allowed to contain iron has a ferromagnetic impurities or hard impurities. In order to prevent bearing and isolation of overheating or burning, avoid by all means is idle running, not allowed to run at less than 30% rated flow. Due to the fundamental magnetic pump to eliminate the leakage of the shaft sealing, at the same time automatic overload protection in power transmission. In the petroleum chemical industry and medicine, etc, when driving power is not big, now has been gradually expanding the application.

import for magnetic pump suction should be how to solve?

the impeller and the pump body has serious friction phenomenon, user conveying for dilute sulphuric acid, the temperature is not high, the density is not high also, so what causes this phenomenon happens, after the technician careful scrutiny, with the video, finally found that turned out to be import pipeline resistance is too large to import negative pressure during the running of pump is too large, eventually make the ring serious wear and tear, impeller forward.

so how do we prevent the import of negative pressure is too high, or, in the case of imported high negative pressure, how to improve the pump, we finally find a solution that is will be turning impeller HouGaiBan, minus increase the positive pressure impeller mouth ring before, to offset the axial force of pump. After a change is good, the pump running stability, have obtained approval to foreign users.
