Description
Technical field
This utility model is related to field of intelligent control technology, especially a kind of pipe network intelligence hydraulic equilibrium regulating system.
Background technology
At present, heat (cold) water that hot (cold) source produces is delivered directly to heat use by pipe network by central heating (cold) system
Family, or by the exchanger in switching station, hot (cold) water is conveyed to the user of secondary pipe network.System is followed by being located at hot (cold) source
Ring pump provides circulation power.Because heat supply (cold) area is generally larger, heat supply (cold) pipeline is long, and switching station is many, and arrangement is complicated, because
This circulating pump is typically chosen higher head to overcome the resistance of whole heat supply (cold) system.Supply (cold) hot systems for indirect, its
Exchange heat stations secondary side and must be provided with Secondary water circulation pump, its lift and flow must are fulfilled for the demand of disadvantageous inhabitant.
In heat supply (cold) system, because the user that pipeline is longer, connect is more, exist from heat between most of user
(cold) source closely overheated (cold) and the hydraulic misadjustment phenomenon of far-end not hot (cold), in order to meet the demand of user's heat (cold), in heat
Under the conditions of (cold) net is unable to reach preferable hydraulic equilibrium, just can only adopt the method for operation of " the little temperature difference, big flow ".This just makes
Hot (cold) user must be flowed through and the flow of unit is not inconsistent with design discharge, add that pump selection is bigger than normal, be chronically at inefficient shape
Run under state, therefore, low, hot (cold) the amount transfer efficiency of water pump efficiency is low.And at each user, room temperature is inconsistent, near-thermal

Hot (cold) system power consumption is big, and the defeated ratio of specific heat of power consumption is big；Hot (cold) source unit is located at circulating-pump outlet so that hot (cold) source unit one
Directly work under high pressure (0.5～1.3MPa), the air due to dissolving in water during using can corrode unit, makes holding of unit
Compressive Strength is gradually reduced, and unit has the not enough potential safety hazard of bearing capacity；The personnel that some operating experiences are enriched can be to each
Valve at user entry is adjusted, and for the few system of user, only need to adjust 1-2 valve, but for big system meeting
There are 30～50 users, in this case, need the equipment that technical staff the holds specialty 30～70km that runs to take the weight of more than 10 day
Polyphony examination just can make system reach poised state, cut debugging enironment badly, or weather is too hot too cold, so that personnel may be gone out
Existing industrial injury probability greatly increases.
