a. Automatic intelligent control technology, no need to be on duty. Flexible working mode can be set to manual or automatic mode.
b.It can be set in accordance with the boiler run automatically, can set a number of different working hours a day, the boiler automatic time-sharing Start the heating, heating group circular cutting, make each contactor using time and frequency are the same, improve the service life of the equipment.
c.The controller automatically controls, calculates and tracks the pressure, and can control the pump and electric heating tube automatically when the load changes, and can also be controlled manually
d.Boiler body is made of boiler pressure vessel steel plate, furnace body and longitudinal and girth weld are automatic welding, and the X-ray flaw detection, small boiler furnace, electromechanical integration, easy to install and matching; The design of boiler body and electric control of large boiler is designed to eliminate the high temperature effect of electrical control in part, and ensure the stable operation of electric control device.
e.The electric heating elements of low surface heat load which meet the requirements of JB / 2379-93 and metal tube heating elements are required. High quality electric filament coat with thick Stainless Steel tube, filled with high purity magnesium oxide powder, the electric heating tube USES long life. Each set of electric heating element adopts flange connection, which has the characteristics of simple structure, high mechanical strength, safe and reliable, and convenient to replace.
a.security:when the boiler is leaking, the power of the circuit breaker can be cut off in a timely manner to ensure the safety of the person.
Water shortage protection: when the boiler is short of water, the heating tube control circuit should be cut off in time to prevent the heating pipe from drying and damage, and the controller will issue a water shortage alarm indicator.
Ground protection: when the boiler casing is charged, the leakage current is imported into the earth by grounding wire to ensure the safety of the person.
Protective earthing wire should be between the earth and usually make good metal connection, often done deep Angle iron, steel pipes buried in the ground earthing body, grounding resistance shall not be greater than 4 Ω. Steam overpressure protection: when the boiler steam pressure exceeds the set limit pressure, the relief valve is activated, releasing steam to reduce the pressure.
Over-current protection: when the boiler is overloaded (overvoltage), the leakage circuit breaker automatically disconnects. 6. Power protection.
b.conveniences:After the electric control box was introduced, the boiler entered (or escaped) fully automatic operation. The water in the boiler is reduced, and the control system automatically replenishes the water from the water tank to the boiler.
c.reasonability:for reasonable and effective use of electricity, particularly the heating power is divided into several segments, and by the automatic cycle controller input (cut off) the user according to the practical need to make sure good after the heating power, just close the corresponding residual current circuit breaker (or press the corresponding switching on-off switch). The section of the heating tube is cut, reducing the impact of the boiler on the grid.
