二、 四大系统组成：

a/市政管网保护系统、b/压力检测稳压系统、c/增压系统、d/智能控制系统。
其中：a.市政管网保护系统：由稳流罐调节、倒流防止器、市政管网保护器组成，为管网叠压专用设备，可与市政管网直接连网、而不存在负压抢水，从而达到节能、无污染目的。
b.压力检测稳压系统：采用压力数显仪、达到0.01；稳压部分采用气压罐，除小流量给水减少水泵启动次数外，还减少压力波动对控制系统的影响。
c.增压系统：由立式多级泵及管阀件组成，是管网叠压给水设备的动力核心，给水能力取决于泵组。
d.智能控制系统：给水专用软件，由液晶触摸屏、变频器、可编程控制器等主要元件组成，是给水设备的神经枢纽。（可根据用户的不同需要，进行专门设计！）

三、特点：
根本不产生负压，可直接与市政管网串接。
不锈钢材质的管路和水泵，全封闭的叠压供水设备，彻底根除二次污染，确保水质的新鲜与纯净。可有效利用市政管网压力，节能效果十分显著。
无需修建水池及水箱，避免了水箱所必需的定期清洁、维护、水质检测等环节；安装方便、占地面积小，可大幅度节省基建投资并缩短施工工期。
管网压力的存在，保证停电不停水。由于系统有一条旁通供水管路与用户管网想通，在停电时加压泵停止工作，自动恢复原有自来水水压的常压供水。

适用范围
　　
住宅，办公楼，商场，宾馆，医院等各类建筑的生活供水。特别适合要求不间断供水场合。 　　
四、组成部分：
产品组成部分： 　　
1，组合式不锈钢水箱（带泵房）。
　　
2，智能化电气控制系统。 　　
3，低噪音不锈钢多级离心泵。 　　
4，无负压进水装置及防倒流装置。 　　
5，不锈钢成套管路。
　　
6，压力，液位信号采集，反馈设施。

五、工作原理：　　

无负压智能箱式泵站工作原理：
1，当检测到自来水压力能满足用户用水压力时，系统直接通过市政管网给用户供水。
　　
2，当检测到自来水压力低于用户用水压力时，系统通过叠加，变频给用户供水。
　　
3，当检测到自来水压力低且接近零时，切断市政管网，进水，系统通过水箱变频方式给用户供水。
　　
4，为防止二次污染，定时通过水箱直接为用户供水。

  Tank no negative pressure water supply equipment

A range of
applications:
a / Domestic
Water: high-rise buildings,
residential water area and
villa
b / public places: such as
hospitals, schools, sports centers, golf
courses, airports
  Civil:
such as hotels, office buildings, department
stores, large sauna,
etc.
c / irrigation
tank: such as parks,
playgrounds, orchards, farms, etc.
d
/ Manufacturing: such as
manufacturing, washing apparatus,
food industry, factories, etc.
 
Other: Pool water and
other forms of transformation

Second, the
four system components:
a
/ municipal pipe network protection
systems, b / regulator pressure
detection system, c / pressurization
system, d / intelligent control
system.
Wherein: a
municipal pipe network protection system:
the regulator steady flow
tank, backflow prevention
device, composed of municipal pipe
network protection for pipe
network overlying special equipment, can be
directly networked with the municipal
pipe network, without the presence
of negative grab
water, so as to achieve energy
saving, pollution purposes.
. B
regulated pressure detection system:
Pressure digital display, accuracy
of 0.01; regulator pressure tank
part, except for a small flow
water pump to reduce the number of
starts, but also reduce the impact of
fluctuations in the pressure control
system.
. C pressurization
system: the vertical multistage pump
and valve member
composition, is the core of
the pipe network overlying water supply equipment,
power, water supply capacity depends on
the pump.
. D intelligent
control system: The company developed
special software KY inspect water
supply, the main components of a liquid
crystal touch screen, inverter, programmable
controllers and other components, is
the nerve center of water supply
equipment. (According to the
different needs of users, specially
designed!)

Three
characteristics:
Does not produce negative
pressure, it can be directly connected in
series with the municipal pipe
network.
Stainless steel piping
and pumps, closed the
overlying water supply equipment, complete
eradication of secondary pollution,
ensure the quality of fresh and
pure. Effective use of the municipal
pipe network pressure, energy-saving effect is
very significant.
No need to build the
pool and water tank, clean
the tank regularly to avoid the
necessary maintenance, water
quality testing and other areas; Easy
installation, small footprint, can be
significant savings in infrastructure investment
and shorten the construction
period.
The presence of the pipe
network pressure to ensure power off the
water. Because the system has a
bypass pipe and the water supply
pipe network users figured pressure pump
to stop working automatically restore the
original water pressure atmospheric
water during power outages.

Part four, :
Product components:
1, modular stainless steel water tank
(pump).
2, the intelligent electrical control
system.
3, low noise stainless steel multistage centrifugal
pump.
4, no negative pressure water device and backflow
prevention device.
5, complete sets of stainless steel pipe.

Five, how it works:
No negative pressure intelligent box-type pumping
stations working principle:
1, when they tested the tap water pressure
meet water users, system directly through the municipal network will supply
water to the user.
2, when they tested the water pressure is lower than the
user water pressure, the system through the overlay, frequency conversion water
supply to users.
3, when they tested the water pressure low and close to
zero, to cut off the municipal pipeline network, water, supply water system with
water tank frequency conversion way to the user.
4, to prevent secondary pollution, timing directly by
water tank water supply for the user
