Water supply method without negative pressure steady flow tank
The non-negative pressure stabilizing tank water supply method is an advanced water supply technology. It uses intelligent control technology and pressure stabilization compensation technology to achieve that the equipment does not generate negative pressure on the municipal pipeline network, while ensuring uninterrupted water supply to the user's pipeline network. The following are the specific classifications and characteristics of the non-negative pressure stabilizing tank water supply method:
I. Main types
Tank-type non-negative pressure water supply equipment
Composition: It is mainly composed of a stabilizing tank (negative pressure stabilizing tank), a non-negative pressure control cabinet, a water pump, a motor, a filter, a backflow preventer, a sensor, an electric contact pressure gauge, a pipeline assembly, a base, etc.
Working principle:
Variable frequency constant pressure water supply: When the water supply of the municipal pipeline network is greater than the user's water consumption, the stabilizing tank type non-negative pressure water supply equipment supplies water with variable frequency constant pressure. At this time, a certain amount of pressurized water is stored in the stabilizing tank.
Eliminate negative pressure: When the user's water consumption increases, the pressure at the connection between the municipal pipeline network and the stabilizing tank drops. When the pressure drops below the relative pressure of 0, the air intake valve of the vacuum suppressor opens, the atmosphere enters the stabilizing tank, and the negative pressure is eliminated.
Water outage shutdown function: When the municipal pipeline network is out of water, the booster unit automatically stops running under the control of the liquid level controller. After the municipal pipeline network water supply is restored, it automatically starts to resume normal water supply.
Small flow sleep function: When the user does not use water or the water consumption is very small, the equipment automatically enters the sleep state (shutdown) and maintains the water supply pressure. When the user resumes water use, the system automatically wakes up and resumes normal water supply.
Power outage and water supply: When the community is out of power, the municipal pipeline network continues to supply water to low-lying users, and the power outage does not stop water. After the equipment resumes power supply, it automatically starts and resumes normal water supply.
Box-type non-negative pressure water supply equipment
Features: A water tank is added on the basis of the tank-type non-negative pressure water supply equipment, which is used to supply water when the water volume or water pressure of the pipeline network is insufficient or even when the pipeline network is out of water.
Working principle: Connected in series with the municipal pipeline network to ensure that no negative pressure is generated on the municipal pipeline network. During the peak water use period, the water in the closed water tank is pressurized by the microcomputer-controlled variable frequency regulating water pump, avoiding the problem of insufficient supply due to the municipal pipeline network. At the same time, the water stored in the non-negative pressure water tank is circulated regularly through intelligent control to ensure fresh and pure water quality.
2. Common features
Make full use of the pressure of the municipal pipeline network: Both devices can make full use of the residual pressure of the municipal pipeline network, and the energy-saving effect is significant.
Avoid negative pressure on the municipal pipeline network: Through intelligent control technology and voltage stabilization compensation technology, ensure that the equipment does not generate negative pressure on the municipal pipeline network and protect the safety of the municipal pipeline network.
Ensure water supply stability: Real-time monitoring and control of pipeline network pressure to ensure uninterrupted water supply to the user pipeline network, and stable water supply pressure.
Energy saving and environmental protection: Reduce the waste of land and water resources, reduce energy consumption and emissions.
High degree of automation: Adopt microcomputer frequency conversion technology and effective negative pressure treatment technology to achieve automatic control and remote monitoring.
