Constant Pressure Water Supply Improvement design pressure water supply controller 1. Water Supply System ??? timing change pump function, so that the working hours of each pump balanced increase the average life of the pump; 2. With the fire pump inspection function, in the fire mode according to the set time regular inspection of fire pumps, fire pumps prevent rust; 3. pressure control up to eight hours, and each time the pressure can be arbitrarily set and achieve timing control switch function; 4. sleep function and ancillary small pump function, energy saving, extended equipment life; 5. having a second target pressure setting and control functions; 6. With the positive and negative feedback function selection, both for water supply, they can use to keep pumping water; 7. boiler feed water control and relief valve pressure range control, control values ??arbitrarily set; 8. With overpressure, low water level, sensor break, inverter failure alarm control functions; 9. Drive appear After the failure, you can choose to automatically transferred frequency operation (pressure range control); 10 automatic fault reset mechanism, adjustable delay; 11 has a fault-finding function, can check the latest alarm contents and time were recorded ten faults; 12 adaptability, can be used for a variety of domestic and foreign brands converter; 13 analog and digital signals used in all optical isolation, anti-jamming; 14 have improved key features; 15 optional RS-485 communication function, standard MODBUS communication protocol for easy connection with PC for configuration control. Pressure water supply controller advantages 1) can achieve up to three sets of main pump station +1 small pump (RF2310) or +1 six main pump station small pump (RF2610) automatic control, each pump can be set to the variable displacement pump or dosing pumps, flexible configuration, fully meet the complex water or fire protection systems. 2) digital chip technology, and realization of the digital operation, PID control, and product miniaturization, with excellent performance. 3) has a high precision pressure control, pressure is stable, the second fire control pressure (dynamic pressure) is set, the system overpressure discharge automatic control, set parameters password lock and many other features, reliable product quality, operation is simple and intuitive, on-site commissioning convenient, it is particularly suitable for a variety of Water Supply System. The application of a constant pressure water supply controller, two residents of the Water Supply System, pump intelligent system 3, 4 residential area of ??water supply, commercial and residential water systems 5, 6 centralized water supply in rural areas, the factory setting constant water supply
