what is no negative pressure water supply equipment
No negative pressure water supply equipment is no negative pressure frequency conversion water supply equipment.The traditional way of water supply cannot be separated from the reservoir, the water in the reservoir is supplied by the water supply, so the pressure water enters the pool and becomes zero, causing a large amount of energy to be wasted.
And no negative pressure water supply equipment is an ideal energy-saving water supply equipment, it is a kind of can directly connect with tap water pipe network, the tap water pipe network does not produce any side effects of secondary water supply equipment, on the basis of the municipal pipe network pressure directly overlying water supply, energy conservation, and also has closed, no pollution, covers an area of small, fast installation, reliable operation, convenient maintenance, and many other advantages.
No negative pressure frequency conversion water supply equipment, automatic intelligent is through the steady flow tank and tap water pipe connected directly, by way of setting secondary pressurized water supply directly and will not produce negative pressure to tap water pipe network equipment.There are mainly water pump unit, no negative pressure steady flow tank, variable frequency water supply control cabinet, valve, instrument, pipeline, equipment base and so on.
Tank no negative pressure water supply equipment equipment normal put into use, no negative pressure steady flow municipal pipeline network of water into the tank, the tank of air from the vent discharge in great quantities, when the air line up, the floating ball float by water in the valve, drive head to the closed position, slowly close the vent, stop the exhaust, prevent water, when the normal steady flow tank water conveying, such as air gathered in a small amount of tank to reasonably, tank water level drops, floating ball drops, the air has a vent discharge.
Equipment during normal operation, when the municipal pipe network water shortage, municipal water inlet pipe tube empty, or steady flow tank pressure below atmospheric pressure, the steady flow tank water level drops, floating ball drops, drive the plug head open, inhaled air and keep the steady flow tank atmospheric pressure, not negative pressure municipal pipe network.
When the pressure in the municipal pipe network is lower than the set pressure required by the user, the pump frequency control operation ensures that the pressure of the user's pipe network meets the requirements of users' water.The higher the water pressure of the municipal pipe network, the lower the speed of the pump, the lower the water pressure of the municipal pipe network, the higher the speed of the pump.When the water supply pressure of the municipal pipe network reaches the user's requirement, the equipment will stop working automatically, and the water of the municipal pipe network shall be directly supplied to the user by the bypass pipe.
Steady flow when the municipal pipeline network of water tank water level is falling, when dropped to the lowest level, steady flow tank level gauge on the signal downtime, equipment automatically stop running and displays a lack of protection signals.
When the power grid is out of power, the equipment is shut down, and the water from the municipal pipe network is supplied directly to the user by the bypass pipe.
