For realizing energy-saving effect preferably; The cooperation of the parameter of all pumps selection is the basis in the energy-saving water supply equipment of highrise building of the present invention; Also will design suitable traffic control rule on this basis: the parameter of general pump is selected and the traffic control rule is: by auxilliary pump assembly operation; The low discharge that provides high and low district to add up to supplies water, and all pumps of at this moment high and low district all do not move; When water supply flow increased, any low district or height were distinguished putting into operation of pump, and its water flow should be not less than 60% of this pump metered flow at least.The nominal parameter of each pump is selected not simultaneously in the energy-saving water supply equipment of highrise building of the present invention; Start and stop criterion, traffic control rule specific to each pump are different; But but because water pump equal operate as normal in the certain excursion of nominal parameter, so the selection of nominal parameter is very strict, particularly when adopting the variable frequency regulating speed control water pump operation; Can in a big way, change water pump characteristic and operation condition, better basis is provided for realizing the optimum operation scheduling.
To different pump parameters, concrete energy-saving run scheduling rule is described below:
Example one: to equipment shown in Figure 1, press the parameter of each pump of table one parameter configuration, consider that high low area flow difference is not too large in the actual engineering, within the specific limits, can control the operation of each pump by table one scheduling rule:
Table one: the parameter of example one each pump of configuration
The conclusion of example one: by above-mentioned rule operation; Total water supply flow that high and low district adds up to need not start any high low area pump, when total water supply flow increases during less than main pump metered flow 70%; Any low district or high district main pump put into operation, and its water flow is not less than 70% of this pump metered flow.
In this example: 2 usefulness 1 are equipped with or 3 usefulness 1 are equipped with if the high low area main pump is configured to; Then participate in more than one of the high low area main pump of operation; Can water supply flow in the table one be continued to increase when formulating scheduling rule; Flow to increasing carries out similar segmentation, and the thinking principle of reference table one control scheduling, is increased the traffic control of each pump to confirm.
In the present technique scheme, the traffic control of each pump of equipment is to take all factors into consideration high and low district to add up to water supply flow and each subregion traffic demand relation, combines each pump parameter to try to achieve the optimal scheduling rule more in a word.
Example two: to equipment shown in Figure 1, press each pump parameter of table two parameter configuration, consider that high low area flow difference is not too large in the actual engineering, within the specific limits, can control the operation of each pump by table two scheduling rule:
Table two: the parameter of example two each pump of configuration
Under device parameter that this is routine and the scheduling rule condition; The total water supply flow that adds up to when high and low district is during less than height district main pump metered flow 90%; Need not start any high low area pump; When total water supply flow increased, any low district main pump put into operation, and its water flow is not less than 60% of this pump metered flow.Any Yi Taigao district main pump puts into operation, and its water flow is not less than 75% of this pump metered flow.
Example three: to equipment shown in Figure 1, the height district main pump metered flow parameter of establishing apolegamy is consistent, and counts 100 as benchmark; Low district main pump comprises one, and its metered flow is 150 than low-capacity pump (being called 150 main pumps), and the specification of all the other low district's main pumps (being called 200 main pumps) is identical; Its metered flow is 200, and the maximum stream flow of establishing all pumps is 110% of its metered flows, and auxilliary pump discharge is identical with high district main pump flow; Metered flow is 100, presses the operation of following each pump of rule-based scheduling:
Table three: the parameter of example three each pump of configuration
This example explanation: when hanging down district or the high main pump configuration parameter of distinguishing not simultaneously; The traffic control of equipment is more flexible; Under the parameter configuration and scheduling rule that this is routine; The operation flow of realizing supporting each main pump of high low area easily can effectively avoid the high low area main pump to operate in middle low discharge poor efficiency operating mode greater than its metered flow 80%.
In the present technique scheme, the traffic control of each pump of equipment is to take all factors into consideration high and low district to add up to water supply flow and each subregion traffic demand relation, combines each pump parameter to try to achieve the optimal scheduling rule more in a word.
