Description

A kind of non-negative pressure water service system and control method
Technical field
The present invention relates to water system technical field, specifically a kind of non-negative pressure water service system.
The invention still further relates to the control method of a kind of non-negative pressure water service system.
Background technology
In order to realize stable water supply, the place such as a lot of residential quarters, industrial enterprise, hotel, office building, hospital, school is all Have single water system.Traditional water system mainly has following two.
(1) water tower water-feeding: first tap water is evacuated to water tower (or top of building water tank), then by water tower from height The pressure that degree produces supplies water to user.But there is a lot of problem, such as water tower and take up an area big, construction trouble, effect in this water system Rate low (water is first evacuated to water tower, waste electric energy).Additionally, due to pressure of supply water with in water tower the height of water relevant, therefore without Method provides constant pressure, and the user of differing heights it is the most different by water pressure.This kind of way of supplying water exits the most gradually at present Market.
(2) power frequency supplies water: the tap water of city planting ductwork is caused cistern, is then transported by the power frequency that is in of certain power Water is delivered to user by the water pump of row.But, from original pressure vanishing after entering pond of the tap water of city planting ductwork, so After start from scratch again when supplying water for user pressurization, this necessarily causes substantial amounts of electric power energy to waste.Additionally, due to water when supplying water Pump is in power frequency operation all the time, and energy consumption is higher.
(3) variable frequency water supply: the tap water of city planting ductwork is caused cistern, uses regimen condition by converter according to user, Drag water pump and be in different running frequency, it is provided that the water of constant pressure uses to user, compared with second in method energy-saving effect obvious. But, cistern water-retention process causes the pressure waste of city planting ductwork equally.Further, above-mentioned three kinds of way of supplying water are required for storing Pond, had both taken place, and has needed often to clean, and water quality easily forms secondary pollution.
Chinese invention patent application description CN104746550A discloses a kind of pipe network laminated press frequency conversion supply equipment master To be made up of filter, backflow preventer, negative pressure canceller, steady-flow tank, ultraviolet ray disinfector, water pump, effusion meter and switch board, Being provided with water level controller in steady-flow tank, for detecting the water level in steady-flow tank, hydrous water level controller is arranged on steady-flow tank Bottom is provided with hydraulic control mouth for wiring, and described switch board is used for detecting steady-flow tank water level, water suction manifold pressure, outfall sewer pressure With by discharge, control the in good time action of negative pressure canceller simultaneously and control water pump automatic start-stop, frequency conversion, switching and number of units increasing Subtract.The invention has the beneficial effects as follows, the present invention has that simple in construction, defencive function be complete, stable and reliable for performance, water supply quality peace Advantages such as full health, and install maintenance scheme, take up an area little, low cost, and available tap water water inlet pipe pressure reaches energy-conservation Effect, thus application will have good practical value and economic results in society in secondary water-supply.But, steady-flow tank directly quilt Being used for as surge tank, the hydraulic pressure in raw water tubes is wasted, and causes loss, adds cost.
