Background technology
Urban water supply is a city lifeblood, is to ensure people's lives, the indispensable material base of developing the economy, and has become the central issue of China's urban construction and the key factor of economic development.Along with the development of economy and the rise of modern high level and super highrise building, requirements at the higher level have been proposed for water supply and energy saving technology and equipment operational reliability.Existing way of supplying water mainly contains pressure water supply, variable frequency water supply, three kinds of patterns of high-level tank water, go through the development and perfection of more than ten years, conventional constant pressure water supply technology has become a kind of main modern water supply pattern, early stage pressure water supply mode is replaced gradually, in recent years Kai Fa non-negative pressure method of water supply has solved the power saving in the multistory building domestic water equipment real time execution preferably, but zone and high level and the super highrise building lower for hydraulic pressure, existing non-negative-pressure variable frequency constant pressure water-supply technology is only utilized municipal network water supply pressure, and it reaches the pump energy saving DeGrain that moves under long-time low discharge and the dead head condition greatly in the water supply volume variation.
Summary of the invention
The purpose of this invention is to provide a kind of reliable, critical component Maintenance free and the energy-conservation universal frequency conversion pressurization and water supply equipment of hygienic environment-protecting, this apparatus adaptability is wide, not only can utilize city planting ductwork hydraulic pressure, and make full use of equipment outlet pressure energy, be the optimum novel supply equipment of modern architecture.
The utility model is achieved through the following technical solutions: circulation is from supercharging energy-saving and frequency-variable waterworks in a kind of, comprise the water water jet device that vacuum inhibition and bascule and bottom thereof connect, the voltage stabilizing compensator, variable frequency pump, general pump, the city planting ductwork water inlet suppresses with vacuum by DRV and bascule is connected, the vacuum that is installed in water water jet device suppresses and the bascule bottom, its in-out end is connected with the voltage stabilizing compensator by DRV, water side and the water inlet that enters variable frequency pump after valve is connected in series, the variable frequency pump delivery port is connected in the flange mode with the compensator bottom by DRV; General pump water inlet serial connection valve suppresses with vacuum and bascule is connected, and its delivery port is connected in series DRV by DRV, valve, outlet pipe and the balance tank top outlet pipe laggard pipe network of becoming owner of in parallel on the outlet pipe of compensator top.
Described compensator serial connection valve prolongs water (flow) direction and is connected in series with water water jet device inlet, and delivery port enters the variable frequency pump water sucking mouth via valve, enters the compensator bottom via valve again, circulation in forming.
Described tap water enters vacuum via DRV to be suppressed and bascule, by water water jet device, enters internal circulation system with the mode of jet supercharging.
Advantage of the present invention is:
(1) need not to build the priming reservoir, equipment can directly be connected in series with municipal network water supply.
(2) eradicate water pollution once again.
(3) with the inner loop mode jet from supercharging, wide adaptability.
(4) equipment is energy-conservation in real time.
(5) jet pump is all steel structure, Maintenance free.
(6) can increase substantially pump head, prolong service life of equipment
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 circulates from supercharging frequency conversion water supply facilities pipe-line system schematic diagram in the utility model.
Among the figure: 1,3,17, be valve, 2, general pump, 4, variable frequency pump, 5, the general pump water inlet pipe, 6, water water jet device, 7, municipal water inlet pipe, 8,10,16,14,15 DRVs, 9, vacuum suppresses and bascule, 11, compensator, 12, the equipment outlet pipe, 13, the general pump outlet pipe
The specific embodiment
During the equipment operation, variable frequency pump 4 moves by Frequency Converter Control in the equipment control cabinet automatically according to the system pressure feedback signal, tap water from municipal pipeline 7 enters in the compensator 11 after variable frequency pump 4 pressurizations, enter water water jet device 6 by compensator 11 through valve 10 again, suck the tap water that enters in vacuum inhibition and the bascule 9 simultaneously, enter variable frequency pump 4 water sucking mouths behind the interflow again, circulation in so forming.Along with the increase of inflow, hydraulic pressure increases gradually in the compensator 11 in inner cyclic process, and water water jet device 6 efficient also increase progressively synchronously, finally reach required pressure.Along with the continuous variation of water supply volume, amount of jet is adjusted accordingly and pipe network water pressure is kept constant.Water water jet device 6 corresponding water amount of inspiration simultaneously during water; Carry out the zero delivery circulation during no water; In the peak water period, start general pump 2 by frequency converter and be incorporated into the power networks, this moment, the variable frequency pump 4 in good time corresponding frequencies that change were to guarantee outlet pipe 12 place's water pressure invariablenesses.During 4 operations of this equipment variable frequency pump, its suction side has utilized water water jet device 6 delivery port hydraulic pressure, make variable frequency pump 4 in low discharge and zero delivery with energy-conservation in real time under the water condition, therefore, this device energy-saving effect is fairly obvious.(successfully the tubing pump of lift 25m being risen to 50m) in the prototype experiment stage
In sum: this system and device by variable frequency control with the supercharging of interior circulation mode of jet, not only utilize city planting ductwork hydraulic pressure, and make full use of equipment outlet pressure energy, solved the power saving when the traditional frequency conversion constant pressure water supply equipment moves continuously preferably under the variable working condition state, satisfied the randomness requirement of water, can comprehensively be fit to different water industrial and minerals and require and really accomplish environmental protection and energy saving.
