Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model water system.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, the utility model water system comprises Variable frequency speed regulation constant pressure water supply equipment, water tower 1 and water supply network 7, wherein water tower is provided with level probe and liquid level relay, and Variable frequency speed regulation constant pressure water supply equipment comprises constant pressure frequency conversion device 9, and wherein constant pressure frequency conversion device 9 is arranged in constant voltage pump house 2.
Described level probe sends the water level of the described water tower collecting to described liquid level relay, and according to described water level, to control described constant pressure frequency conversion device be described water tower retaining to described liquid level relay or stop as described water tower retaining.When water level is during lower than lowest water level value, level probe gathers the water level of water tower and sends liquid level relay to, liquid level relay contacting frequency converter starts loop, make constant pressure frequency conversion device 9 drive water pump 6, water pump 6 is water tower retaining from the interior extraction water of well 5, in order to avoid water supply network inner inflatable maintain ductwork pressure; Rising along with water level in water tower, when water level arrives peak level value, level probe gathers the water level of water tower and sends liquid level relay to, and liquid level relay contact disconnects frequency converter and starts loop, stop utilizing constant pressure frequency conversion device 9 for water tower retaining, in order to avoid water overflows from aqua storage tank.
Water tower is in eminence, and the pipeline 8 of water tower both can be used as outlet conduit, also can be used as retaining pipeline, and the pipeline 8 of water tower communicates with water supply network 7, so the effect of water tower has two: the one, supply water, the 2nd, the pressure of increase water supply network.
Producing the busy season, when production department 4 interior without watering equipment directly from pipeline water intaking, during the pressure stability of water supply network, constant pressure frequency conversion device can be water tower water-feeding, to guarantee there is the sufficient water yield in the aqua storage tank of water tower.A large amount of water intakings once the watering equipment of production department 4 from pipeline and cause pressure moment of water supply network 7 to reduce, because the pressure of water supply network 7 reduces, water in the aqua storage tank of water tower flows out downwards along the pipeline of water tower, has increased the pressure of water supply network and has supplied water to watering equipment.Because the hydraulic pressure of water tower supplements the pressure that has increased the water supply network that moment reduces, make the pressure of water supply network keep stable state, avoided the water of other except production department place in water supply network to occur the phenomenon of insufficient water having guaranteed that water system supplies water reposefully for each water place as residential block 3.Complete when the watering equipment water intaking of production department 4, the pressure of water supply network increases, and makes the water in the aqua storage tank of water tower stop flowing downward, and water tower no longer supplements the pressure of water supply network, and it is normal that the pressure of water supply network recovers.Because water tower is to the supplementing of the pressure of water supply network, make constant pressure frequency conversion device to accelerate frequently and to slow down, increased the application life of constant pressure frequency conversion device.
