Description
Technical field
The utility model relates to water supply pressurized equipment field, especially a kind of stabilizing compensation formula non-negative pressure water-supply installation.
Background technology
At present, along with the quickening of urbanization process, city area is increasing, build more and more higher, affected by this, the laying area of city tap-water company city planting ductwork is also increasing, the distance of water place and Running-water Company's water supply point is more and more far away, certainly will cause the overall pressure of supply water of water supply network more and more lower, in city, the place of pressure of supply water deficiency is also just more and more, in the situation that water factory's discharge pressure cannot improve, many urban lifes supply water and still continue to use storage-type secondary water-supply structure, build pond or water tank at underground or roof, tap water is all put into pond or water tank, due to pond or the storing water in water tank time long, water flow is poor, there is structural defect in pond sealing simultaneously, so microorganism, mosquitoes etc. are very easily immersed, cause water pollution.The water coming from tap water pipe network is put into pond, the whole vanishing of original hydraulic pressure, so will build pump house, the pressurization again of starting from scratch is supplied water, waste energy.Repair pond and build pump house and take up room greatly, when power failure, cannot supply water to user.
What also have many local employings is that the mode supplying water without negative pressure pressurization supplies water, this supply equipment mainly comprises the water tank being communicated with running water pipe, water tank is communicated with service pipe by control piper, the duty of control piper is by electrical control cubicles control, its operating principle is before tap water forced feed user, first tap water is stored in water tank, like this, in the time of water low-valley interval, tap water pressure is met consumers' demand, supply water to user by tap water self pressure, in the time of the water use peak period, tap water pressure can not be met consumers' demand, now electrical control cubicles will be supplied with user after the retaining pressurization in water tank by control piper, meet user's when water demand of section in office thereby realize, the application of tradition non-negative pressure water-supply installation is very extensive, but the weak point of traditional water supply equipment is: due to the restriction of water supply chamber and water tank volume, retaining in water tank can only meet the water demand of the water use peak phase user in the short time, after the retaining in water tank is finished, just stop supplying water, when retaining reach a certain amount of after just again start supply water, very trouble, can not meet the round-the-clock user's request of user.
Utility model content
Based on above current demand and traditional shortcoming without negative pressure pressurization supply equipment; technical problem to be solved in the utility model is to provide a kind of without building pond, water tank and pump house; can prevent that water quality is contaminated; and the compensation non-negative pressure water-supply installation of a kind of Intellight voltage-stabilizing with water-shortage protection device simple in structure, reasonable in design, easy to use.
Stabilizing compensation formula non-negative pressure water-supply installation of the present utility model comprises stabilizing compensation tank, constant voltage systems stabilisation and electrical control cabinet, described stabilizing compensation tank upper left quarter has a water inlet, water inlet and city planting ductwork feed pipe connect and compose inlet pipeline, vacuum table, valve, strainer, backflow preventer are housed on inlet pipeline successively, on stabilizing compensation tank top, pressure sensor and negative pressure inhibition device are also housed, have delivery port, blowoff valve and a liquid level sensor in stabilizing compensation tank bottom;
Described constant voltage systems stabilisation comprises pressure sensor, diaphragm-type air-compressed tank and three variable frequency pumps, and three variable frequency pumps are respectively 1# pump, 2# pump and 3# pump; Three pumps are variable frequency regulating speed control, can according to setting pressure and user's water situation automatically successively or stack start operation and can automatically regulate running frequency, after system starts, electrical control cabinet control system regulates the operating frequency of water pump and the number of units that drops into water pump automatically according to discharge pressure.When discharge pressure lower than set operating pressure time, water pump of variable frequency starting, and strengthen gradually the operating frequency of feed pump, ensure that user's supply channel pressure that pressure sensor detects reaches setting operating pressure, when the operating frequency of a pump reaches specified operating frequency, and discharge pressure is now still lower than operating pressure, system automatically superposes and starts an other pump so, and strengthen gradually the operating frequency of feed pump, until user's supply channel pressure that pressure sensor detects reaches setting operating pressure;
When user's water supply volume reduces, when now pressure sensor detected pressures will be higher than setting pressure, control system will reduce the operating frequency of water pump under current variable frequency work state until user's supply channel pressure that pressure sensor detects reaches setting operating pressure, if the operating frequency of this pump is lower than lowest operating frequency, and discharge pressure is now still higher than setting pressure, control system will be closed a pump that reaches lowest operating frequency so, and reduces an other pump until detected pressures reaches required setting operating pressure;
Further in the time only needing a pump operation and when long in single pump running time, for protection water pump and the electric machine control system other pump same frequency that will automatically switch moves; So circulation, standby operation each other, the working life that can protect to greatest extent and extend water pump;
On user's feed pipe, connect a large amount of users; still there is the water batch of high-frequency low discharge at water low peak period; these water supply volumes will affect and reduce loine pressure suddenly; cause system frequent in short-term restart water pump; we connect a diaphragm-type air-compressed tank on user's feed pipe for this reason, voltage stabilizing and protection variable frequency pump group frequent starting fast to greatest extent.
Electrical control cabinet is used for the data of the each link of collecting device and setting and control the operation of whole equipment, can be by important parameter and the running status of electrical control color touch screen facilities for observation cashier's office in a shop.On the delivery port of equipment, also connect a flow meter, in order to calculate output and it is presented on electrical control cabinet touch-screen.
