Industrial boilers, automatic continuous water supply equipment using the most advanced new ways of shunt decompression for boiler feed water, continuous stable to water changes, no back pressure, adjust the drum water level changes within the scope of 10MM usually consists of three parts: Magnetic sensors, controllers, and HR Series three-way electric control valve. 
 A, model and specifications 
 Magnetron-type automatic continuous water supply equipment specifications: DN32 \ \ the DN40 \ \ of DN50 \ \ DN65 
 A magnetron sensor (25kg/cm2) 
 2 controller 160x80x170: HR-UHM-291D-G 
 3.HR series of three electric control valve: HR94A4W 
 Second, the main technical indicators 
 The application of boiler capacity is less than or equal to 20t / h 
 Applicable boiler nominal pressure of less than or equal to 30kg/cm2 
 Water supply way continuous 
 Regulate the drum water level range is less than 10mm 
 Traffic rated flow from 0 to 100% 
 Automatically open the pump stops the water level +30 to-30mm 
 High and low alarm water level +50 to-50mm 
 Very low interlock shutdown protection of the water level-50mm 
 Power 220v 50hz 
 Ambient temperature of 0-45 degrees 
 Relative humidity less than 85% 
 Free of excessive dust around and no corrosion of the explosive gas 
 Work less than 25Hz dual vibration amplitude is less than 0.1mm 
 The output terminal capacity 220v 1.5A non inductive load 
 Third, the water supply system diagram 
 Fourth, the main advantage of 
 An adjustment to the amount of water change is continuous smooth, linear, usually between 10 mm to control the drum water level change, not nearly to improve the reliability of the safe operation of boiler and steam greatly improved quality 
 Run time of 2 boiler feed water continuous flows through the economizer, it does not produce the gasification phenomena and the water hammer phenomenon, to ensure that the economizer safe operation 
 The structure is simple and reliable, less failure, long life. Installation, use, and easy maintenance 
 With significant energy saving effect: due to the circulating water flows through the economizer heat to get the full exchange, practice has proved in the case of room temperature water supply, can feed water temperature to 60 degrees or more, with in addition to oxygen boiler, deaerator steam consumption can be reduced. The feed water temperature 6 ° C can be reduced to 1% fuel depletion, and therefore has a significant energy saving effect.
