A circulating pump and a pressure sensor are arranged on the main pipeline; the circulating pump and the pressure sensor are connected to a main controller; temperature sensors and electric control valves are arranged on the branch pipelines; the temperature sensors and the electric control valves are connected to respective branch controllers; and the branch controllers are connected to the main controller. The variable flow system has the advantages of convenience and energy conservation.
Description
Technical field:
The utility model belongs to the medium transmission field, is specifically related to a kind of with regional waterpower adjustment and the mutually unified unsteady flow amount control system of pump variable frequency adjusting.
Technical background:
Present variable flow system adopts at each regional arm mostly dynamic balance valve or static balancing valve is installed, so that MEDIA FLOW keeps balance roughly; User side has all been adorned electric two-way valve simultaneously, will turn-off Twoway valves after the user side temperature reaches setting temperature; And use variable frequency pump to carry out the adjusting of unsteady flow amount.And variable frequency adjustment mode wherein adopts following three kinds of modes: (1) is divided, the temperature difference of water-collecting machine keeps certain; (2) pressure reduction of branch, water-collecting machine keeps certain; (3) pressure reduction of least favorable end keeps certain.Mode 1 is divided, the temperature difference of water-collecting machine keeps certain, can play the energy-conservation effect of throttling, but might the throttling transition and cause some terminal undercurrent amount, thus the normal use of influence end.Mode 2, the pressure reduction of branch, water-collecting machine keep certain, can play the energy-conservation effect of throttling, but after terminal total water yield reduces, the local resistance of main pipe and branch pipe(tube) and prolong the journey resistance and will reduce, and the branch of this moment, the pressure reduction of water-collecting machine remain unchanged, and then part energy have been wasted.Mode 3, the pressure reduction of least favorable end keep certain, and this is a kind of comparatively reasonable method, determine than difficult but least favorable is terminal, and after pipe characteristic changed, the least favorable point can change.
Summary of the invention:
For overcoming the above-mentioned technological deficiency of existing product, the utility model provides a kind of having of energy consumption of hydraulically balanced variable flow system of saving more.
The technical solution adopted in the utility model is as follows: a kind ofly have a hydraulically balanced variable flow system, comprise main pipe and each bypass line.Whole system is provided with recycle pump and pressure transducer, recycle pump and pressure transducer are connected on the master controller, be respectively arranged with return water temperature sensor, electric control valve on each bypass line, return water temperature sensor on each bypass line, electric control valve are connected on separately the sub-controller, all join end to end between each sub-controller and between the master controller.
Each branch road that the utility model has hydraulically balanced variable flow system is provided with supply water temperature sensor and flowmeter.
Each sub-controller that the utility model has hydraulically balanced variable flow system is provided with demand switch.
Use of the present utility model a kind of when having hydraulically balanced variable flow system, at first each branch road carries out the adjusting of electric control valve according to the height of return water temperature, when return water temperature is higher than the backwater setting temperature, drives big electric control valve, otherwise, then turn down electric control valve.The return water temperature value can be set as required in advance.After adjusting return water temperature, read the valve position parameter of electric control valve.When whole motorized adjustment valve position all when subtracting frequently setting value, reduce the frequency of variable frequency pump, when one valve position being arranged when increasing frequently setting value in whole electric control valves, increase frequency.Variable frequency pump has the upper and lower limit frequency setting value, and variable frequency pump will run between the upper and lower frequency.When design load, the pressure of the branch/water-collecting machine of adjusting also writes down the frequency of this moment, can be used as the upper limit of control frequency, and the surplus that designs is saved.
The utlity model has following advantage: 1, regulate because the unnecessary energy consumption that the pipeline pressure drop that flow reduces is produced saves, promptly reduce the energy consumption of waterpower transmission to greatest extent, regulate the balance of pipe network simultaneously automatically by pump variable frequency.2, the control of the demand of regional cold will direct and variable flow system hook.3, make each loop distribution according to need cold by adjusting to electric control valve.When a certain zone no longer needs cooling, utilize electric control valve it can be turn-offed.
