KSWG non-negative-pressure (without suction lift) pipe network

pressure boosting stable current water supply whole set equipment

(hereinafter referred to as the equipment) is the new generation product

developed by our company on the basis of upgrading the original KSGP

frequency conversion constant pressure water supply series product.

According to the regulations in ules of Urban Water Supply it

is forbidden to directly install pump on urban public water supply pipes

to pump water! This is because that the negative pressure produced during

pumping will influence water use of other uses in the surroundings, or

even cause damage of pipes.

Therefore, during engineering design, the water pool or water tank

shall be firstly built. The urban water supply is put into the water pool

first and then is pressurized to the water supply pipe network of users.

In the case 1. Large investment. Cost for the building of water pool

(water tank), cost for installation of new water treatment equipment as

the water source in water pool is easily polluted an d cost of daily and

regular cleaning and sterilization of water pool (water tank)

shall be taken into consideration.

2. Water source is easily polluted. As the water pool (water tank) is

open, impurities, microbes and small animal bodies may easily pollute

the water source, especially in summer, the water is easily deteriorated

and smells off.

3. Waste of energy The pressure of urban p ipe network firstly

changes to zero and then start to pressurize from zero. The original

pressure is wasted and the model of pressure boosting pump is enhanced.

4. Waste of water source Water seepage, water running, water leakage

and evaporation may occur in the water pool. Moreover, regular rinsing

and sterilization costs labor and water.

5. High noise When the water level in the water pool (water tank)

descends due to water use, the large noise of water flow from tap water

and noise caused by operation of old style DL pump may exist.

The above problems can be thoroughly solved after adopting KSWG

non-negative-pressure (without suction lift) pipe network pressure

boosting stable current water supply whole set equipment produced by

our company.

1. When the pressure of tap water is lower than the set pressure

required by user, the control system will automatically control the

frequency converter to start the operation through frequency conversion

soft starting until the actual working pressure of user pipe network is

equal to the set pressure. The frequency converter controls the frequency

conversion pump to operate at a constant rotation speed. The higher the

pressure of tap water is, the lower the rotation speed of frequency

conversion pump is, and vice versa. When the pressure of tap water

equals to the set pressure, the frequency conversion pump will delay the

time and sleep, which makes full use of the original pressure of tap water

to ensure that the pressure required by user is constant. When the pressure

drops to the awakening value, the water pump will be automatically

awakened.

2. The water inlet of frequency conversion pump is connected with

the stainless steel stable current compensator, and the microcomputer is

always inspecting the pressure inside the stable current compensator.

Through the inspection to pressure of inlet water and automatic vacuum

suppresser, it is ensured that there is no negative pressure inside the

stable current compensator so as to guarantee the normal water supply

of tap water pipe network.

3. When tap water stops water supply, the equipment will automatically

stop. When the water supply is available, the equipment will automatically

start. In case of power cut, the normal pressure low area water supply

of tap water will automatically resume.

4. When producing instant negative pressure, please stop all power

frequency pumps first and then delay the time of frequency conversion

speed reduction without stopping the machine, which not only ensures

water use for user but also alleviates the condition of negative pressure.

1. Saving a total investment of 70%.

No need to build water pool or water tank. Directly connected with

the tap water pipe for pressure boosting water supply, which makes full

use of the original pressure of tap water and reduces model of water pump

(original water pump requires 60M lift, and the current one requires

only 30M.)

2. Water quality is pure

The pure tap water is directly supplied to user after pressure boosting

by the equipment. It is connected in sealed condition, which is absolutely

isolated from the air.

3. Saving water of 20%

Hermetic structure prevents the occurrence of running, dripping,

leakage and seepage, and the water wasted for regular cleaning and

sterilization. It is directly connected with tap water pipe.

4. Saving power of 70%

It makes full use of the original pressure of tap water pipe and

compensates the pressure amount that differs. When the tap water satisfies

the requirements, the equipment will stop its operation. The effect of

energy saving is so prominent that it can reach above 70%.

5. Saving space and installation time

No need to build water pool or install water tank with the whole set

equipment leaving the factory. After reaching the site, the water inlet

pipe and the water output pipe of tap water of user is directly connected

with the equipment with simple construction, short construction period

and small landing area.

6. Saving manpower and material resources

The water quality is not polluted through adopting the equipment.

No need to install sterilization equipment. Twice pollution is prevented.

The equipment is provided with small pressure stab ilizing tank, which

can further save the investment. As no water pool or water tank is requir ed,

the use is very economic that it saves the costs for regular cleaning and

sterilization.

7. Low noise

As the water pump is directly connected with tap water through

stable current compensator, there is no large noise of water flow from

tap water. The system adopts stainless steel light vertical multistage

centri fugal pump, which can gre atly reduce the noise caused by operation

of water pump.

8. Advanced control system

The equipment applies fuzzy control and integrated control etc.

world advanced control technology and is provided with powerful

remote supervising function and wireless supervising function (optional).

The model selection for KSWG non-negative-pressure (without

suction lift) pipe network pressure boosting stable current water supply

whole set equipment is based on the water inlet amount of tap water

(specified by tap water pipe diameter pressure and length etc. conditions),

actual w ater con sumption, height of buildings etc. data. The perfor mance

form of model selection provided by our company complies with the

following principles:

1. The flow indicated in the form is designed according to the unit.

The equipment model is of common model. Our company can redesign

according to special requirements of customers.

2. The equipment flow indicated in the form does not include flow

of standby pump. The quantity of water pump in the form includes two

sets for use.

3. The specification of stable current compensator recommended

in the form is evaluated and calculated accord ing to the conditions that

tap water satisfies customer requirements. If the tap water pipe diameter

is very slim or the pressure is very low and the water inlet amount can't

satisfy the demands at peak time of water use, the volume of stable current

compensator shall be recalculated. The recommended formulae are as

follows:

V volume=(Q outlet-Q inlet) t

3 Q inlet water inlet amount of tap water at peak time of water use (m /h)

3 Q outlet water consumption by customer at peak time of water use (m /h)

t continuous period at peak time of water use (h)

(about 35-42Hz) when no water is used. 4015 is awakening value, which is

set as the percentage of const ant pressure (generally 80% of 4020). For

modificati on of other parameters, please refer to SAMI, GS user manual

for details. It is noted that 0127 is the displayed value of actual pressure

value of pipe network, refer to the value of 0127 for 4020. For example,

when the pressure of pipe network is 0.5Mpa, 4020 can be set as 20%. 3202

is the lower limit of pressure of whole set system plus pump pressure

(generally 80% of 4020). 1401 is set as 8. 3205 is the upper limit of pressure

of whole set system minus pump pressure (generally 98% of 4020). 1402

is set as 9.
