The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model is mainly by plate type heat exchanger 1, frequency conversion moisturizing water pump 2, circulating pump 3, electric control valve 4, ball valve 5, frequency conversion collector 13, controller 6 and switch board (not shown) form, described plate type heat exchanger advances, answer back respectively and to be connected with heat supply pipeline 7 and primary water pipeline 7-1, be provided with electric control valve 4 between heat supply pipeline and plate type heat exchanger import, plate type heat exchanger delivery port and water return outlet are connected with secondary heat supply pipeline 8 and secondary returning waterpipe 8-1 respectively, described controller is connected with outdoor temperature sensor 9 and temperature sensor 10 and pressure sensor 11, described temperature sensor and pressure sensor are connected with the secondary heat supply pipeline with a heat supply pipeline respectively.The bypass of described secondary returning waterpipe is provided with frequency conversion moisturizing water pump 2 and replenishing water tank of water 12.Be provided with liquid level sensor 15 in described replenishing water tank of water, described liquid level sensor is passed to remote terminal by remote protocol by liquid level information.By liquid level sensor, rely on remote protocol that liquid level information is passed to remote terminal, the Real-Time Monitoring of water supply tank liquid level, prevent that sky regimen condition from occurring.Be respectively equipped with ball valve 5 on a described heat supply, water return pipeline and secondary heat supply, water return pipeline.Described frequency conversion collector acquisition controller energy data, energy data described in this example is, voltage, electric current, meritorious efficiency, idle efficiency and momentary efficiency, and be passed to remote terminal 14 by remote protocol, described remote terminal is accepted energy data, and send control signal and be passed to the frequency conversion collector by remote protocol, make the frequency conversion collector control controller action.
Operation principle:
By remote protocol, make remote terminal control controller action by the frequency conversion collector, thereby reach the Long-distance Control to whole central heating monitoring station.
The system and control cabinet connects, and overtemperature, superpressure, the decompression of heat network system had to interlock protection and warning function.
O-volt protection: when the secondary side pressure of return water sets value lower than lower bound, the moisturizing frequency converter wakes up, and automatic water replenishing system puts into operation, starts moisturizing.The automatic water replenishing system rear secondary side pressure of return water that puts into operation still continues to reduce and sends warning.
Overtemperature prote: when the secondary side supply water temperature surpasses setting value, and the primary side return water temperature is closed the primary side electric control valve while surpassing setting value.
Overpressure protection: it is out of service and close the primary side electric control valve that secondary side water main pressure surpasses the setting value circulating pump.
System has power-failure protecting, incoming call from the function opened.
