Pump industry suppliers - Magnetic pump common faults is how cause

common magnetic pump failure

in the magnetic field of shafts is all normal, rolling bearing and magneto inside the rotor and the seal will cause calorific value in operation process. On the one hand, the work of ascension temperature, on the other hand to reduce transmission output power.

on the other hand, it leads to a lot of inconvenience, easy vaporization of liquid, magnetic water pump transportation along with temperature rising, a magnetic transmission system to reduce the output power is a continuous curve, generally in magnetic limit temperature of the following, the transmitting ability of reducing is reversible, and around the limit temperature is not reversible, magnetic refrigeration transport volume after damage can't repair.

in a unique magnetic pump condition, when the magnetic coupling of dislocation, vortex calorific value will significantly increase, the temperature will rise significantly. If not properly handled, can cause magnetic coupling invalid demagnetization, magnetic tile and thus design of magnetic pump should be into one of the refrigeration system. Of not easy gasification medium, refrigeration system generally consists of pump impeller exit or export total flow, part of the population of rolling bearing and the magnetic drive, easy to gasification medium, should improve heat exchanger or tank liquid pump, prevent heat back to import absorption, has a solid residue or ferromagnetic particles should take into account the dielectric filters, dielectric temperature, refrigeration, shall be taken into consideration to ensure that the magnetic coupling is not beyond the limit working temperature, when fully considering the speed is not enough, be sure to check the motor's speed than if everything is normal, it can be to accurately measure with tachometer.

belongs to magnetic pump axial sealing of pump, the pump and drive motor are enclosed in a covered by underwater concrete medium pressure container, the pressure vessel can only be packing seal. Withdrew the traditional centrifugal pump has this kind of structure of the circular sealing device, can guarantee completely without leakage, the pump magnetic pump and motor connected together, motor rotor of motor and pump impeller fixed on the same shaft, used to block set of the motor rotor and the motor stator space, motor rotor in the transport medium, its driving force according to the motor stator electromagnetic field to the motor rotor.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern self-priming pump performance testing means, equipment is excellent. Main production ZA, ZAO, ZE petrochemical pump, CZ chemical process water pump, magnetic pump, IH chemical pump, forced circulation pump, SPP chemical mixed-flow pump of 28 kinds of material, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts. 。
