Non-negative Pressure Water Supply Systerm in a Building

NFWG series non negative pressure frequency convention water supply equipment is a new type frequency convention equipment. There are two types. One is cabinet model equipment, the other is tank model equipment. The equipment can be connected to the municipal water supply network where the pressure is not high enough. Use sensor to detect the outlet pressure and compare with the setting value to calculate the pressure needed to be boosted, pump quantity, motor rotation. The equipment can make full use of the original pressure of the municipal water supply network. It will not cause negative pressure of the municipal water supply network. It uses the stainless steel non negative pressure tank to replace the old pool to avoid second pollution. It is the new general energy saving product in the water supply industry.

Main application

1. Residential water supply: High building, residential area, villa, etc.
2. Public places: Hospital, university, gymnasium, golf course, airport, etc.
3. Commercial building: Hotel, office building, department store, large-scale sauna center.
4. Irrigation: Park, playing round, garden, farm, etc.
5. Manufacturing industry: Manufacturing, lavation equipment, food industry, factory, etc.
6. Other: Rebuild of water pool or other form.

Features

1. Non-negative pressure

The system can connect to the municipal water supply system to boost it and will not cause negative pressure for the municipal water supply system.

2. High quality, PC controls:

Invented by us, have multi-function, can supply high standard precise control. It arrives to the advance level in the world.

3. Boosting

When the equipment is running, it can use the pressure that water supply network supplies and boost base on this, Compared to suck water from the normal water pool, it can use less pump or lower the rotation to save energy.

4. Not stop water supply when power is off

When the power supply is out off power, system can supply water with 747D and. Bypass, etc, that is, system can supply water with the municipal water supply pressure.

5. Clean

The flow parts are all stainless steel which is the material of food grade, it is conform to the international water related rules. The cabinet type non-negative device can ensure the water in the cabinet to be circulated by the usage of residents. The closed type non-negative device can circulate real-timely to ensure the safety of the water.

6. Energy saving

The system needs not the water pool etc. To store the water, which save the space. The system works high efficiently, which can save 60% energy. There is pressure of the municipal water network. When running, the system only need to boost on the pressure of municipal water network. The system need not to be monitored by people, and need not the water pool, etc. And there is no water quality handling machine. It is not needed to be cleaned and disinfected timely. So energy saving is obvious

Q:We just replaced the motor on our water pump that burnt out but we are still getting no water pressure. My father in law did a lot of test stuff on it he thinks it's the foot valve. Well I've been trying to call every where get quotes but NOT 1 of the places I called is answering their phone for some reason. So how much dose it usually run to have someone come fix your foot valve so I have an idea to tell my husband?: If you want to purchase a foot valve I would suggest you purchase a brass one with a stainless steel screen. where I live that peticular one would cost approximatly $20.00 Also you would need a brass male adapter. Approximately $8.00 and gear clamps All Stainless steel X2 $1.50ea One question: is there water in the pump body? if not then you either have a leak either in the water line leading to the foot valve or the footvalve leakes itself. if there are other questions e-mail Licensed pump installer. good luck. If father inlaw is comfortable doing tests then should be comfortable changing footvalve. with a little bit of help. is it a drilled well or a dug well?

Q:motor overheats but no leak. water just boils in resorvoir. is it hard to do it on my own?: you may have air pocket.look for the perg valve to let the air out. if your water pump leaks it is bad

Q:My friends car is a 1997 jeep wrangler. The belt broke and she took it in to get it replaced and they told her metal from the pully that broke got into the water pumpand they have to replace that to? WTF? it makes a squealing noise and they want to charge her another 300 for that! we just don't understand how that could be if the pump isn't even leaking?: I don't think you wouldn't necessarily know if the pump is leaking. It would just make the car overheat because the coolant wouldn't get circulated. The reason it costs so much to have a water-pump replaced is because it is buried deep in the engine bay near the timing belt and it takes several hours to replace it. The actual cost of the water pump is probably under $100.

Q:quot;A tank has the shape of an inverted circular cone (point at the bottom) with height 10 feet and radius 4 feet. The tank is full of water. We pump out water (to a pipe at the top of the tank) until the water level is 5 feet from the bottom. The work W required to do this is given byquot;I know how to find it if it's a right circular cylinder, but how do I adjust for the changing area? Also would a and b = 0 and 5? Thanks ahead of time!: calculate the amount of water U start with by computing volume of cone: V = 1/3πr?h {r = 4', h = 10'} V = 0.333π(4)?(10) = 167.55 ft? calculate the amount of water remaining in cone after pumping is done: V = 0.333π(2)?(5) = 20.944 ft? calculate the volume of water pumped: 167.55 - 20.944 = 146.6 ft? 1 ft? of water weighs 62.4 lb, calculate weight of water removed: 146.6(62.4) = 9148 lbs The Center of Mass of the water in the cone (when h = 10') is at 1/4 of 10 ft = 2.5 ft high The Center of Mass of the water in the cone (when h = 5') is at 1/4 of 5 ft = 1.25 ft height The Center of C.of M. change = 1.25 + (2.5 - 1.25)/2 = 1.25+0.625 = 1.875 ft If we consider that the Center of Mass of the water removed was at 1.875 ft, All the water removed was then lifted an average of 10 - 1.875 = 8.125 ft Work done = W = (9148)(8.125) = 74,300 ft-lbs ANS

Q:how often do i need to change a timing belt and water pump on my car? also, how much should it cost? should i have it done at the dealers or at a small mechanic shop if i chose to? which would be best? what are steps when having timing belt change?: If it's Japanese, every 90,000 miles. If American, every 60,000 miles. Just recently changed belt and water pump on my Honda for $400 at an independent. Dealer is more expensive.

Q:how to replace water pump 97 pontiac bonneville?: It depends on which engine you have, with or without a supercharger. The non-supercharged engine is a piece of cake. the supercharged one is a bit of a pain to get at the water pump. On the non-supercharged engine, all you need to do is remove the serpentine belt, the water pump pulley and the bolts that hold the water pump to the front cover. I have detailed instructions if you send me your email address I can give them to you. They are from GM Service Information website. I can't give you the link to the website because I have to enter a password to enter the site through work.

Q:I have a '97 Chevy S-10 2.2 with 208K miles. Today on the way to work the heat cut out suddenly.I have had an issue with my engine where the temp will go up and down while on the highway but maxes out at like 215. Today after the heat cut out it was getting up near the redline before going back down to 150.I made sure the coolant was good before coming home but on the way home it was doing the same thing. I changed the thermostat but it's still doing the same thing.When I rev the engine I can see the upper radiator hose collapsing so it seems like there's a clog somewhere but I don't know how to find it. I guess it could be the water pump but then what is causing the suction on the upper radiator hose?Anyone have any ideas?: if the top radiator is collapsing then the radiator is clogged up ! i doubt it,s the water pump ! try this ! once the engine is hot, shut it down and feel the radiator fins next to the fan ! if you feel cold spots then the radiator is clogged in some places ! flush out the whole cooling system ! i had a ford truck that did the same thing until i bought a new radiator !

Q:When did the pump start?: The promotion of water is very important to human life and production. There are various ancient water appliances, such as Egypt's chain pump (seventeenth Century BC), China shadoof (seventeenth Century BC), Burton (Eleventh Century BC) and water (first Century ad). The famous spiral rods invented by Archimedes in the third Century BC can lift water to a few meters in a steady and continuous way, and the principle is still used by modern screw pumps.In 200 BC, the ancient Greek fire pump craftsmen invented by Kurt Siby Lucius is a kind of piston pump has the most original, the main components of a typical piston pump piston pump, but only after the steam engine was developed rapidly.1840~1850 years, the United States invented Worthington pump cylinder and steam cylinder opposite, the direct impact of the piston pump, marking the formation of modern piston pumps. Nineteenth Century was the climax of the development of piston pumps, which were already used in a variety of machines, such as water presses. However, with the rapid increase in water demand, from 1920s, the piston pumps with low speed and large flow were gradually replaced by high-speed centrifugal pumps and rotary pumps. But in the field of high pressure and small flow, reciprocating pump still occupies the main position, especially diaphragm pump and plunger pump have their own advantages and are used more and more.

Q:I just bought a house and we have well water. When I went out to change the filter on the pump I noticed a valve leaking...I went to check on it and noticed it had two settings if you will. one says System and the other says by pass if I move the lever to system the leak stops, if I move it back to bypass the leak continues...question is which one should I have it set on and what is the purpose?: Okay, Adam, we also have a well and just put in a new one. The setting that says System means that the water is running through the filter. The setting that says by pass means that the water is NOT running through the filter. You will have water either way in your house (or you should). It is just either, it is running through the filter, or it is not. I hope I have helped. gram
