Information technology is self-priming magnetic pump industry upgrade

self-priming magnetic pump is applied to the working principle of magnetic couplings self-priming centrifugal pump, self-priming magnetic water pump with outer recirculation structure of axial pump, pump body by suction liquid chamber, liquid storage chamber and volute, reflux hole, gas-liquid separation chamber and other parts. Self-priming magnetic pump, especially the inflammable, explosive, volatile liquid pump, the working principle of self-priming magnetic pump is a pump starts, in under the action of centrifugal force, the remaining liquid in the suction chamber and into the air in the liquid line is impeller into air water mixture, stir the mixture enters the gas-liquid separation chamber through the volute, as at a slower pace, cause gas water separation, air is being exhausted from port pumping liquid, liquid by the inside hole to return to the pump, after many cycles, into the air in the fluid pipeline is net, make the pump in a certain vacuum degree, achieve self-priming function. Self-priming magnetic pump caused by cavitation problem: the main causes of cavitation are pump inlet tube more resistance than large and medium gas, insufficient irrigation water pump, pump suction can not wait for a reason. The hardest by the cavitation of pump, pump when cavitation occurs severe vibration, balance, will cause the impeller pump bearings, rotor or damaged. This is a common cause of self-priming magnetic pump failure. No small medium or medium flow: make the rotor spindle and stability of bearing dry rubbing, stubble bearings. Self-priming magnetic pump is provided by the transport medium for sliding bearing lubrication and cooling, in the absence of open inlet valve and outlet valve, sliding bearing caused by free of lubrication and cooling medium and high temperature and damage. Damage of sleeve: the magnetic coupling of magnetic pump is cooling medium by the pump, if there is a hard particle medium, it is easy to cause scratch or wear of sleeve, sometimes if improper maintenance methods are also likely to cause damage of sleeve. Prevent particles from entering the ( 1) There is no ferromagnetic impurities, particles into the magnetic transmission device and the bearing friction pair. （ 2) Conveying crystallizable or precipitation of media should be timely wash (after Stop the pump to the pump cavity perfusion after water, running clean emissions after 1 min) To ensure the service life of sliding bearing. （ 3) Transport medium containing solid particles, filter at the entrance of self-priming magnetic pump flow tube. To prevent the demagnetization ( 1) Magnetic moment not too small. （ 2) Should be run under specified conditions of temperature, medium temperature exceeds bid is forbidden. To outside surface of sleeve of self-priming magnetic pump installed platinum resistance temperature sensor detecting the rise of temperature of the annular region, so that when temperature overrun alarm or shutdown. To prevent dry friction ( 1) It is forbidden to idling. （ 2) It is forbidden to media time. （ 3) Under the condition of the outlet valve closed, self-priming magnetic pump continuous operation time shall not be more than 2 min, in case the magnetic actuator overheating and failure. Self-priming magnetic water pump is the working principle of magnetic couplings used in centrifugal pump of the new product, reasonable design, advanced technology, with fully sealed, without leakage, corrosion resistance, the characteristics of self-priming magnetic pump performance reach the advanced level of similar foreign products. Self-priming magnetic pump with static seal instead of dynamic seal, make self-priming magnetic pump flow components in a completely sealed state, self-priming magnetic pump and other pump mechanical seal were completely solved inevitably run, take, drop all of the disease, self-priming magnetic pump corrosion resistance, high strength reinforced polypropylene, four fluorine alloy, silicon nitride, graphite, carbon steel, ceramics, jade as manufacturing material, self-priming magnetic pump and stainless steel connection frame, for customers to solve the old often replace the connecting rack for air corrosion. Self-priming magnetic pump which have the function of CQF magnetic drive pump, self-priming and set at a suit, without bottom valve and water, self-priming magnetic pump has good self-priming performance, with short time, high efficiency, self-priming magnetic pump and in the case of no liquid and no-load operation, self-priming height of 4 meters, so the self-priming magnetic pump has good corrosion resistance, and can make the medium from pollution. Self-priming magnetic pump is widely used in petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection enterprise in the production process flow of corrosive liquids do not contain iron impurities, self-priming magnetic pump is particularly applicable to flammable, explosive, toxic and volatile, precious liquids. Self-priming magnetic pump in the field of petrochemical industry, more and more manufacturers, require no leakage of the conveying medium technology environment, in some special occasions, such as conveying hot oil or with particles medium ( Such as sewage treatment) , as well as the chemical production process, more pressing need to select the ideal pump type without leakage.
