Information technology is a powerful guarantee for the upgrading of self sucking magnetic pump industry
Self suction magnetic pump is the principle of permanent magnet coupling applied to self suction centrifugal pump, self suction magnetic pump adopts external mixing axial pump structure, pump body is composed of suction chamber, liquid storage chamber, volute, reflux hole, gas liquid separation chamber and other components. Reasonable design, advanced technology, magnetic pump has a full seal, no leakage, corrosion resistance, advanced level self-priming magnetic pump performance to similar foreign products. Magnetic pump compact structure, beautiful appearance, small size, low noise, reliable operation, convenient maintenance and use of magnetic pump can be widely. Used in chemical, pharmaceutical, petroleum, food, electroplating, film and photographic development, scientific research institutions, defense industry and other units of pumping acid, lye, oil, rare valuable liquid, plating liquid, volatile liquid, and circulating water equipment. Magnetic pump especially flammable, explosive, volatile liquid pump, working principle of self magnetic pump is the pump start, under the action of centrifugal force, the residual liquid suction chamber and the liquid inlet and the air in the pipeline by the impeller mixing into gas water mixture, the mixture. The shell enters the gas-liquid separation chamber. As the speed slows down, the air and water are separated. The air is discharged from the liquid outlet of the pump, and the liquid is returned to the pump through the backwater hole. After repeated cycles, the air in the liquid inlet pipe is discharged, so that a vacuum degree is formed in the pump, and the self suction effect is achieved.
1., the problem of self priming magnetic pump caused by cavitation. The main causes of cavitation are pump inlet pipe resistance, transportation medium gas phase, insufficient irrigation pump and insufficient pump inlet head. The damage of the pump is the most harmful to the pump. When the cavitation occurs, the pump is vibrant and the balance is seriously damaged, which will result in the damage of the pump bearing, the rotor or the impeller. This is a common cause of the failure of the self-priming magnetic pump.
2. no medium or transport medium flow small: rotor spindle and stable bearings dry friction, burning crushing bearings. The self suction magnetic pump is lubricated and cooled by the conveying medium to the sliding bearing. Without the inlet or outlet valve or the outlet valve, the sliding bearing will cause high temperature damage due to the lubrication and cooling without conveying medium.
