Develop rapidly along with socioeconomic, water is strengthened day by day to people's lives and industrial influence, and people improve constantly the quality of water supply and the requirement of security reliability.And how much user's water be often change, so insufficient water or the superfluous situation that supplies water happen occasionally.And the imbalance between water and water supply concentrated reflection is on the pressure that supplies water, and namely water is many and supply water fewly, and then pressure is low; Water is few and supply water manyly, and then pressure is big.Keep the constant of pressure of supply water, can make supply water and water between keep balance, namely water supplies water also manyly for a long time, water supplies water also few after a little while, thereby has improved the quality that supplies water.Constant pressure water supply system is very important for some industry or special user.For example in some manufacturing process, if tap water supply insufficient pressure or cut off the water supply in short-term for some reason may influence product quality, make product rejection and device damage when serious.And for example during breaking out of fire, if pressure of supply water is not enough or anhydrous supply, can not put out a fire rapidly, may cause heavy economic losses and casualties.Advanced automatic technology, mechanics of communication, network technology etc. are applied to the water supply field, become the requirement new to water undertaking.
Become under the historical conditions of characteristics of the times saving water and energy, the country of our this water resource and electric energy shortage, relatively backward always in aspect technology such as municipal water supply, residential quarter water supply, high rise building water supplies for a long time, automaticity is lower.Mainly be that in the water use peak phase, the quantity delivered of water usually is lower than demand owing to be subjected to the restriction of outmoded supply equipment and transfer pipeline, hydraulic pressure occur and reduce the water phenomenon that supply falls short of demand.Traditional solution is to adopt high level cistern, water tower and various air pressure tank to carry out the retaining pressurization, and the resistance that relies on baffle plate and valve is regulated discharge.This potential energy or pressure water supply mode by water has shortcomings such as floor space is big, investment is high, the pump motor startup is frequent, power consumption is many, pipe network water pressure is unstable, the booster phenomenon frequent, leakage is serious; Not only living water use is subjected to secondary pollution easily, and the frequent unlatching of pump motor makes the equipment failure rate height, maintenance, safeguard and also have difficulties, and as water tower traditional water system, aspect maintenance and upgrade-system, also be very expensive.Therefore, how utilizing effective water source and electric energy to guarantee all trades and professions normal water supply, has been extremely urgent.
The utility model content
Deficiency at the prior art existence, the purpose of this utility model is a kind of high-rise building constant pressure water supply electrical control system of design, have not only that quality of water supply height, flexibility are strong, motor rise braking steadily, no water hammer effect, advantages such as floor space is little, equipment investment is few, noise is low, and stability and the reliability of water system have been improved, water saving, energy-saving effect is remarkable, has good social benefit and economic benefit.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of high-rise building constant pressure water supply electrical control system, comprise reservoir, PLC controller, pressure transmitter, liquid level instrument, water injection valve and group of motors, described PLC controller is mounted on the pressure transmitter on the water pipe, the water injection valve of liquid level instrument, group of motors and reservoir in the reservoir, the outlet pipe of described group of motors is provided with life fire-fighting switching valve, and described life fire-fighting switching valve connects the PLC controller.
Preferably, described group of motors comprise at least one frequency converter and many water pumps, the input of described water pump connects the output of power frequency or frequency converter.
Preferably, the input of described water pump is provided with strainer, and the output of described water pump is provided with flap valve.
Preferably, described PLC controller is connected with warning device.
Preferably, described PLC controller inside is provided with the PID controller.
The beneficial effects of the utility model:
1, the utility model can be traditional fire-fighting, life two cover water systems comprehensively in a system, by special method, take into account characteristics and otherness that life, fire-fighting are supplied water separately, guarantee that high-quality life supplies water under the normal condition, can guarantee under the fire fighting state fire water supply reliably again.
2, the utility model is directly given building water supply, in the low constant voltage of handling well under the animation, under the situation of the high constant voltage of fire fighting state, both saved one-time investment, having reduced floor space, reduced maintenance and the management of equipment simultaneously, is to have very much advantage economically.
3, remove traditional water tank, constant speed water supplying pump mode, made life water system reduce the secondary pollution of water quality, and avoided the powerful impact of constant speed water supplying pump to system, prolonged the application life of equipment, improved quality of water supply.
4, system is clearly aspect energy-conservation.Native system is adjusted the different water yield of water pump output by different feedback pressure values, and this had both saved the traditional energy of employing controlling opening of valve consumption on valve, had also saved the frequent start-stop of water pump to the impact energy of pipe network system.
