5, high-frequency electromagnetic boiler is different from present combustion gas, fuel oil, Electric heating, it is the change in operation principle, the product of this new and effective, high energy-conservation, low cost, high security, existing combustion gas, oil burning boiler, boilers heated electrically will be replaced, in family expenses, commercialization, industry etc., there is extensive use.
6, induction heating pipe can not adopt the material that the conductance such as aluminium, copper is high, prevents high frequency electric excessive and damages high-power electronic device, being advisable with stainless steel tank body.
7, the variable frequency induction boilers heated electrically of new structure, by two cover variable-frequency power sources control device, achieve the structure of a boilers heated electrically two hearts, two power controls are all controlled automatically by PLC, under normal circumstances, start a set of variable-frequency power sources control device, variable-frequency power sources control device controls solenoid and runs, make induction heating pipe heat and heat trnasfer to the medium flowing through boilers heated electrically, when one of them variable-frequency power sources control device breaks down, PLC controls directly to close this power control, start another power control, ensure that the running status of whole boilers heated electrically, ensure that boilers heated electrically can not be shut down, heating can not be affected, and while heating, also can keep in repair boilers heated electrically, satisfactory for result.
7, further, boilers heated electrically provides dual heating method, can make a choice arbitrarily at electrically heated rod and solenoid two kinds of mode of heatings, or uses two kinds of mode of heatings simultaneously, makes the scope of application of variable frequency induction electromagnetic boiler wider.
8, through magnetized water, the character such as pH value, surface tension, electrical conductivity, dissolved oxygen amount, penetration all there occurs change.Magnetized drinking water can increase biomembranous permeability, reduces blood viscosity, keeps blood elasticity, has prevention effect to calculus, skin disease.The famous physician's Li Shizhen (1518-1593 A.D.) of China was just pointed out before more than 500 years, effects such as " going sore fistula, longue skin, Long Drinks to make us son, should enter wine " that the glassware for drinking water crossed through magnetization treatment has
