3.Introduction to High-rise Negative Pressure-Free Water Supply:
Negative pressure-free water supply equipment utilizes the pressure of the municipal pipe network to form a closed and continuous pressure-boosting water supply mode, which saves energy effectively and avoids secondary water pollution. It is an extension and development of variable frequency constant pressure water supply equipment.
The so-called negative pressure-free water supply equipment usually refers to variable frequency negative pressure-free water supply equipment, which is directly connected to the water supply pipe network for pressure boosting. Traditional water supply methods rely on water tanks. The water in the water tank usually comes from the tap water pipe, and the pressure drops to zero after entering the water tank, resulting in a waste of energy.
Negative pressure-free water supply equipment is an ideal energy-saving water supply equipment. It can be directly connected to the tap water pipe network without causing any adverse effects on the pipe network. It directly superimposes and supplies water on the basis of the pressure of the municipal pipe network, saving energy. It also has many advantages such as fully enclosed, pollution-free, small footprint, quick installation, reliable operation, and convenient maintenance.
Negative pressure-free water supply equipment mainly consists of negative pressure stabilizing tank, pressure tank (diaphragm or bladder expansion tank), negative pressure control cabinet, water pump, high-pressure rubber flexible joint, motor, filter, backflow preventer, sensor, electric contact pressure gauge, pipeline components, base, etc.
Negative pressure-free water supply equipment ensures uninterrupted water supply to the pipe network through intelligent control technology and pressure stabilizing compensation technology, without generating negative pressure on the municipal pipe network. The flow controller used by the equipment can automatically adjust the input water volume from the municipal pipe network while maintaining the minimum service pressure, ensuring that the municipal pipe network does not generate negative pressure. During peak water use periods, the energy storage device releases a certain pressure of nitrogen gas that is pre-charged, ensuring that the water in the high-pressure chamber of the pressure stabilizing compensation tank is compensated with a certain pressure. Within a certain period, it can supplement the insufficient water volume from the municipal pipe network.
Through the bidirectional compensator, energy is stored in the pressure stabilizing compensation tank during low water use periods, which stabilizes and compensates the user pipeline. During nighttime and low-flow water supply, a small expansion tank can be used to supply water to prevent frequent start-up of water pumps. It fully utilizes the pressure of the municipal pipe network, resulting in significant energy savings. If the water pump is directly connected to the municipal pipe network, there is no need to build a water tank. It is directly connected to the municipal pipe network.
However, according to China’s urban water supply regulations, in order to prevent the influence on the water use of surrounding residents, domestic and industrial water pumps are not allowed to be directly installed on the municipal pipe network. In order to solve the problem that the water supply equipment can be connected in series on the municipal water supply pipe network without generating negative pressure and without affecting the water use of other users, it is necessary to add a negative pressure-free flow controller, a compartmentalized pressure stabilizing compensation tank, a bidirectional compensator, etc. between the water pump inlet and the municipal pipe network. The negative pressure-free flow controller always monitors the pressure of the municipal pipe network, ensuring that the municipal pipe network does not generate negative pressure while fully utilizing the original pressure of the municipal pipe network.
