TYPES Full-automatic(Frequency Conversion) Constan

Product Features1, equipment and fire control center linkage, automatic fire into the fire status and linkage with feedback interface. 2, fire pump start-up frequency can be used directly starter, since the step-down start lotus, Y- buck activated thyristor soft-start control, frequency conversion constant pressure control, etc., to meet different application requirements. 3, with overvoltage, undervoltage, overcurrent, short circuit, lack phase, water shortage, such as failure alarm and protection. 4, Fire Lord, spare pump with each other back-up function, the main pump failure of the standby pump to work automatically. 5, may be required in accordance with the installation of dual-power users to switch functions, or reprovision a separate dual-power switch cabinets, Lord, prepare power can automatically or manually switch the main power blackout, automatic standby power input, the main power is restored power supply When standby power automatically exit. 6, according to user requirements with automatic data logging function, or low-frequency automatic data logging function, when the main pump inspection by Units start running, has stopped pump failure alarm, in order to avoid fire pump does not run long-term arising from corrosion of bearings, electrical damp, and so die impeller card failure, to ensure that the device is in good condition. Inspection process signals received automatic fire exit inspection status, entered the running state of the fire. Inspection frequency discharge valve to open automatically to ensure the fire is not over-pressure pipe network. 7, device can also be an additional Building Automation (BA) interface, and the terminal computer networking, remote monitoring of computer implementation.
