The shortcomings of traditional water supply equipment

1, the secondary pollution due to the cistern or tank material itself issues likely to breed algae and direct contact with the air and pool water , air, dust and bacteria easy access to the water , so water secondary pollution.
2, can not make full use of energy will have some pressure into the pool of water in the tank , the pressure of the secondary pressure system from scratch , you can not take advantage of any original pipe network pressure , so not fully rational use of energy .
3 , property management trouble laborious cleaning of large reservoirs , water is affected, management trouble.
4 , the initial large investment to build reservoirs or tanks, requires a large investment in civil engineering ; pressurized equipment because it is from zero pressure , pressure pump selection is relatively large , but also requires a large upfront investment.
5 , no economic pressure to run a large selection of equipment , operation consumes more energy , use uneconomical.
6, the installation trouble construction pool construction cycle is long, large projects , manpower into large , complex process, once the leakage phenomenon, difficult to repair , post-maintenance trouble.
7 , covers a large pool or water tank needs to build up a large place , which for our land resources are increasingly strained , it is undoubtedly a school waste of real estate , the cost of land , the same a waste.
8, the power that ordinary frequency of water supply without water pump stops working during a power outage , all users without water.

Pressurized water supply equipment without negative pressure piping advantage

1 Health pollution device is fully sealed operation, foreign matter does not enter the system ; ZP membrane filtration device elimination of negative bacteria in the air blocked and will not enter the system ; regulator balancer using food-grade stainless steel rustproof paint or production, will not breed algae, non-polluting products truly meet people's increasing demands for drinking trends .
2 does not waste energy pressurized water supply equipment without negative pressure pipe directly connected in series with the pipe network , on the basis of the existing pipe network pressure superimposed on the desired pressure , the number of poor , not much , to take advantage of the remainder of the pipe network pressure , not will produce negative pressure, without causing waste of energy , in line with national energy conservation requirements.
3 convenient property management , simple pressurized water supply equipment without negative pressure pipes for the digital control automatic operation, automatic shut down water and electricity , water supply is automatically boot ; Because no pollution , so no trouble cleaning .
4 provinces because no upfront investment to build reservoirs or tanks , it saves a lot of construction investment , and because use of the water pipe network and pressure , without pressure from zero , so the pressure pump selection is small, reduce equipment investment .
5 running costs low pressure pump selection because the small and multi- pump system , low water peak at a pump enough to meet water needs , water peak period will start when other pumps , so equipment energy consumption very low , reducing operating costs.
6 Simple installation , no negative pressure pump pressurized water supply equipment for the complete supply users simply join the site and out of water , the construction period is short , easy to install .
7 small footprint because you do not build the pool or water tank , significant savings in floor space, the real estate business can take advantage of improved land conservation estate utilization. Conservation of land resources in line with national requirements .
8 power supply can be maintained because the device has a public water supply pipeline network communicate directly with the user , although the pressure pump to stop working during a power outage , but users still maintain the underlying architecture of water .

Description:
1 above is commonly used models, but also be designed according to user requirements and specific engineering parameters.
2 total flow devices do not include spare pump flow, no more spare pump equipment, spare pump can be installed according to user requirements.
3 volume regulator balancer should be calculated and adjusted according to user diameter tap water.
4 is the choice of equipment mounting space horizontal regulator balancer proposals, to meet the conditions of installation, and the installation site can be adjusted according to the specific circumstances of the user's requirements.

Scope:
1 . The middle of a public water supply network booster pump station .
2 . Various residential quarters and office buildings, hotels and other civil construction .
3 can be used in conjunction with pool or water tank has been built to reduce energy consumption.
4 can be combined with the existing frequency of water supply equipment. Further energy saving.
5 kinds of industrial production and domestic water systems.


Order details:
No negative pressure pipe pressurized water supply equipment selection to be based on the amount of tap water users ( ie tap diameter, pressure ) , the user's actual water consumption, building height and other data to determine and choose from a selection of equipment voltage balancer table provided that the volume of water to meet peak flow amount of the user , if the water is very small diameter , the water flow can not meet the requirements of the peak before the supply voltage V balancer needs to be recalculated , the user needs to provide the following data:
 tap water supply water peak (m3 / h)
 water peak water users (m3 / h)
 duration of the water peak (h)


Ordering Information:
1 . The user can type in Table I provided , choose the device type , such as users have special requirements , the company can design and supply by your requirements, the complete sets of equipment supply.
2 on behalf of clients such as device model needs me , please provide detailed engineering parameters , including user diameter water pressure ; Users actual consumption ; most unfavorable water points height.

Figure, if the pipeline pressure is higher than the set pressure value, the pump unit 4 does not work, the water can be piped through the check valve 11 to reach 6 water supply.
If the pressure drops below the set pressure value, the electrical contacts 10 to the inverter cabinet 7 NC signal frequency soft start pressurized water pump unit 4 , line 6 until the user set pressure value is equal to the actual pressure , frequency counters 7 NC control water pump 4 runs at a constant pressure.
When water peak , the pipeline pressure drops below the set pressure value , remote signal to the inverter 8 7 gauge CNC cabinet, the inverter frequency is increased , increasing the speed of the pump unit 4 , the amount of water increases, the outlet pressure rises allowing users to pipe 6 is equal to the actual pressure set pressure value.
When the water trough when the pipe network pressure rises above the set pressure value , remote signal to the inverter 8 7 gauge CNC cabinet, the inverter frequency is reduced , the water pump 4 speed is reduced, allowing users to set equal to the actual pressure pipe 6 pressure, if the frequency is reduced to the pump unit 4 has no actual flow , while in the idle state, the pump unit 4 automatically stop working, water reaches the user directly through the check valve 11 water pipe 6 .
If tap water is greater than the voltage balancer water pump unit 3 or 4 of the water to maintain a balance between the two , then ZP membrane filtration vacuum the entire regulator balancer suppressor 2 3 seclusion , maintain normal water supply ; When the regulator balance when influent water pump unit 3 is less than 4 , ZP membrane filtration vacuum suppressor two balancer entire regulator 3 and the outside world , the destruction of a negative pressure to ensure normal water supply pipe network , and does not affect the well other water users .
When the water without water , the pump unit 4 is still working until the water level dropped regulator balancer 3 level controller to automatically shut down after a set level, boot automatically after runoff .
When a power outage, water pump does not work, the water can reach the user directly through the check valve 11 water supply pipe 6 , when an incoming call automatically turn the unit back to normal water supply.
