Described volume control device is for controlling the frequency-conversion control cabinet of secondary circulating pump operating mode.
Described volume control device is to be connected on the pipeline of secondary circulating pump and with described climate compensator to keep the controlled motor-operated control valve that is connected.
Compared with prior art, the beneficial effects of the utility model are:
This project of heating system of the present utility model adopts secondary water-supply temperature automatic adjustment technology, Real Time Monitoring is carried out in variation to outdoor temperature, and with outdoor temperature as parameter by RHVC automatically distribute the heating the one secondary net water yield, solve heating power operating mode and the hydraulic regime imbalance of heating system comprehensively, reach the optimal operational condition of the whole network, to greatest extent energy savings; It can guarantee the safety and steady operation of central heating system; Improve heating effect, by improving user's satisfaction rate, improve the social benefit of heating enterprise.Also can transform a circulating pump simultaneously, original high-power, high-lift pump is changed to low lift and large flow rate low-power water pump, further save electric power.
Description of drawings
Figure 1 shows that control system structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, heating system of the present utility model comprises and utilizes steam power plant as the heat source 1 of central heating, in order to the hot water of carrying described heat source 1 or the first-level pipeline network 2 of steam, through secondary circulating pump 4 be connected in parallel to described first-level pipeline network thermal substation 3 and by with the hot user 9 of described thermal substation heat supply.
Wherein, the hyperthermia and superheating steam that provides for steam power plant forms high-temperature-hot-water and delivers to each thermal substation by first-level pipeline network 2 through power plant's heat exchange station vapor-water heat exchanger, described first-level pipeline network comprises circulating water line and one-level water circulating pump 12, by the work of one-level water circulating pump with heat delivery to each thermal substation.
Described thermal substation comprise with the hot water of first-level pipeline network introduce thermal substation secondary circulating pump 4, can control the frequency-conversion control cabinet 6 of described secondary circulating pump operating mode, in order to finish first-level pipeline network and secondary network heat exchange water-water heat exchanger, secondary network circulation line 13, be arranged on the secondary network circulation line in order to promoting the secondary network circulating pump 8 of water circulation and climate compensator.
Described climate compensator comprises and the controlled temperature data processing module that is connected of described frequency-conversion control cabinet, be separately positioned on the temperature sensor at secondary network circulation line water outlet and water return outlet place, but be arranged on the outdoor temperature sensor 10 of open air sensing outdoor temperature, described temperature data processing module 5 can receive each temperature sensor signal and obtain temperature value everywhere, then the different time of setting according to the situation of change of outdoor temperature and user is to the requirement of indoor temperature, automatically calculate and obtain appropriate confession, return water temperature, then compare according to the temperature at the temperature of calculating and delivery port and water return outlet place and comparison result is sent to frequency-conversion control cabinet, operating frequency by described frequency-conversion control cabinet control secondary circulating pump, improve or reduce pushing quantity, make the heating load of heating custom system satisfy heating user's requirement.That is, when outdoor temperature changed, in order to keep the relatively stable of indoor temperature, heating user's supply water temperature also will correspondingly change.When knowing that by outdoor temperature sensor outdoor temperature reduces, in order to keep original indoor temperature, supply water temperature in the secondary network circulation line should suitably improve, this moment, climate compensator was passed to frequency-conversion control cabinet with control information, frequency-conversion control cabinet strengthens the rotating speed of secondary circulating pump, it is more to make first-level pipeline network enter the hot water flow of heat exchanger (or water-water jet) of thermal substation, and behind heat exchanger (or water-water jet), heating user's supply water temperature can raise; When outdoor temperature rises, carry out opposite adjusting, thereby the return water temperature of boiler is raise, reduce the output load of boiler unit, reach the purpose of energy-saving run.
A kind of distortion as above-described embodiment, can not adopt VFC for the secondary circulating pump, motor-operated control valve of pipeline series connection at the secondary circulating pump, by control the aperture of automatically controlled control valve in conjunction with the temperature of climate compensator, thereby change the actual flow that enters thermal substation, can realize above-mentioned purpose equally.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
