Abstract
A water supplying device of a middle-and-high area shared auxiliary pump is composed of a high area main pump, a middle area main pump, an auxiliary pump body, a reducing valve, an electronic control valve and a controller. The water inlet end of the high area main pump, the water inlet end of the middle area main pump and the water inlet end of the auxiliary pump body are connected with a municipal pipe. The water outlet end of the high area main pump is connected with a high level water point. The water outlet end of the middle area main pump is connected with a middle level water point. The water outlet end of the auxiliary pump body is connected with the water inlet end of the electronic control valve. The water outlet end of the electronic control valve is respectively connected with the high level water point and the middle level water point. The reducing valve is arranged on a pipeline between the water outlet end of the electronic control valve and the middle level water point. The high area main pump, the middle area main pump, the auxiliary pump body and the electronic control valve are electrically connected with the controller and controlled by the controller. The water supplying device has the advantages that the hardware investment is small in the system erecting process, maintaining cost is relatively low, the number of standby devices is small when the system operates, energy consumption is low, and the operation cost is relatively small.
Description
Technical field
The utility model relates to a kind of secondary water-supply technology, relates in particular to the supply equipment of the shared attached pump in a kind of Zhong Gao district.
Background technology
In highrise building, the demand difference of the floor of differing heights to pressure of supply water, steady in order to ensure discharge pressure, the general two cover supply equipments that adopt of existing secondary water supply system respectively high and low floor supply water; From the viewpoint of saving running cost and reducing equipment loss, main, the mutual system architecture for subsequent use of attached pump that single cover supply equipment generally adopts, when water supply volume is larger, (as very large in water supply volume by water supplying pump, also may lead, attached pump works simultaneously), water supply volume hour, by attached water supplying pump; The problem existing is: the supply equipment that high-storey is supplied water comprises the attached pump in main pump He Gao district of Liao Gao district, the supply equipment that low floor is supplied water comprises the attached pump in main pump He Zhong district of Liao Zhong district, this just need to arrange 4 water pumps in secondary water supply system, cause the cost of system building and maintaining all higher, and 4 water pumps all need standby for a long time, power consumption is larger, and running cost is higher.
Utility model content
For the problem in background technology, the utility model proposes the supply equipment of the shared attached pump in a kind of Zhong Gao district, its structure is: described supply equipment You Gao district main pump, middle district main pump, attached pump, reducing valve, electrically-controlled valve and controller composition; The water inlet end of described high district main pump, middle district main pump and attached pump is all connected with city planting ductwork; The water side of described high district main pump is connected with water spot with high level; The water side of described middle district main pump is connected with water spot with middle level; The water side of described attached pump is connected with the water inlet end of electrically-controlled valve, and the water side of electrically-controlled valve is connected with water spot and middle level water spot with high level respectively; Described reducing valve is arranged on the pipeline between electrically-controlled valve water side and middle level water spot; High district main pump, middle district main pump, attached pump and electrically-controlled valve are all electrically connected with controller and are controlled by controller (wherein, electrically-controlled valve is for controlling attached pump water end (W.E.) and conducting or cut-off with pipeline between water spot, and reducing valve exports the hydraulic pressure of middle level water spot to for reducing attached pump).
Core improvement of the present invention is: only adopt 3 water pumps to be respectively high level water spot and middle level water spot pressure of supply water is provided, wherein two pumps is respectively as high district main pump He Zhong district main pump, and an other pump is as attached pump.
Operating principle of the present utility model is: when water use peak, controller control electrically-controlled valve pumps water end (W.E.) and with the pipeline cut-off between water spot by attached, now, high district main pump He Zhong district main pump is respectively high level water spot and middle level water spot hydraulic pressure (now attached pump is in resting state) is provided; When non-water use peak, high district main pump He Zhong district main pump enters resting state, now, controller control electrically-controlled valve pumps water end (W.E.) and with the pipeline conducting between water spot by attached, by attached pump simultaneously for high level provides pressurization with water spot and middle level water spot, due to high level with water spot and middle level water spot the demand property of there are differences to hydraulic pressure, therefore, with being provided with reducing valve on the pipeline between water spot, hydraulic pressure is carried out to certain step-down processing at attached pump and middle level, to ensure that the middle level stable water pressure of water spot is in goal pressure scope.
Useful technique effect of the present utility model is: less input for hardware when system building, and care and maintenance cost is relatively low, and the equipment of awaiting orders when system operation is more less, and energy consumption is lower, and running cost is also relatively less.
Brief description of the drawings
Fig. 1, principle schematic of the present utility model;
In figure, the corresponding title of each mark is respectively: high district main pump 1, middle district main pump 2, attached pump 3, reducing valve 4, electrically-controlled valve 5, city planting ductwork 6, high level water spot 7, water spot 8 for middle level.
Detailed description of the invention
Zhong Gao district shares a supply equipment for attached pump, and its innovation is: described supply equipment You Gao district main pump 1, middle district main pump 2, attached pump 3, reducing valve 4, electrically-controlled valve 5 and controller composition; The water inlet end of described high district main pump 1, middle district main pump 2 and attached pump 3 is all connected with city planting ductwork; The water side of described high district main pump 1 is connected with water spot with high level; The water side of described middle district main pump 2 is connected with water spot with middle level; The water side of described attached pump 3 is connected with the water inlet end of electrically-controlled valve 5, and the water side of electrically-controlled valve 5 is connected with water spot and middle level water spot with high level respectively; Described reducing valve 4 is arranged on the pipeline between electrically-controlled valve 5 water sides and middle level water spot; High district main pump 1, middle district main pump 2, attached pump 3 and electrically-controlled valve 5 are all electrically connected with controller and are controlled by controller.
