The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of unattended central heating monitoring station, mainly by plate type heat exchanger 1, frequency conversion moisturizing water pump 2, circulating pump 3, electric control valve 4, ball valve 5, controller 6 and switch board (not shown) constitute, 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 the 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 water return pipeline 8-1 respectively, described controller is connected with outdoor temperature sensor 9 and (TE) temperature sensor 10 and (PE) pressure sensor 11, and 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 water return pipeline is provided with frequency conversion moisturizing water pump 2 and replenishing water tank of water 12.Be respectively equipped with ball valve 5 on a described heat supply, water return pipeline and secondary heat supply, the water return pipeline.
Operation principle:
System is connected with switch board, and overtemperature, superpressure, the decompression of heat network system had interlock protection and warning function.
O-volt protection: when the secondary side pressure of return water was lower than the lower bound setting value, the moisturizing frequency converter woke up, and the automatic water supplement system puts into operation, the beginning moisturizing.The automatic water supplement system back secondary side pressure of return water that puts into operation still continues to reduce and then 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 when 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 that opens.
Temperature control, field controller is controlled the primary side electric control valve according to outdoor temperature sensor, secondary side return water temperature or secondary side for the backwater mean temperature, regulates the once flow of net heating agent automatically, realizes that once " amount " of net regulated.Thereby further control the supply water temperature of secondary net, make it, realize that " matter " of secondary net is regulated, reduced the waste of heat according to pattern or the curve motion set.
Pressure control is according to the pressure of supply water of secondary side setting or for backwater pressure reduction, by the running frequency of Frequency Converter Control water circulating pump.According to the moisturizing pressure of setting,, saved the loss of electric energy to greatest extent by the running frequency of Frequency Converter Control small pump.Magnetic valve is opened and is sluiced when system pressure surpasses setting pressure.
Realize the distribution according to need of hot net water dynamic balance and heat, guarantee that the near-end user indoor temperature is too high to cause heat waste that remote subscriber is not complained, just " comfortable, energy-conservation " principle.
The welding ball valve fault rate of the circulating pump of configuration Grandfos brand and small pump, Finland naval is low in system, and 10 years non-maintaining; All on-site transfer instrument all adopt import to guarantee the accuracy of transmission parameter, have effectively reduced the maintenance work in later stage.
Thermal efficiency height according to the selected different heat exchanger template of different parameters, guarantees high heat transfer coefficient, has improved heat exchange efficiency.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
