Non negative pressure variable frequency water supply equipment for high-rise buildings. Non negative pressure water supply equipment has low cost and no pollution

Description :

Non negative pressure variable frequency water supply equipmentIt is a new type of variable frequency water supply equipment. It is divided into box type non negative pressure equipment and tank type non negative pressure equipment. The equipment is directly connected to the tap water network, making full use of the existing pressure of the tap water network to supply water directly or indirectly. Compared with traditional water supply, under the same water demand, relatively smaller power pumps and control equipment can be selected. At the same time, in the case of low flow water consumption at night, tap water pressure can be used to directly supply water without starting the pump, saving later operating costs. Therefore, non negative pressure water supply equipment is a new generation of energy-saving products in the water supply field, and is the development and extension of variable frequency water supply equipment.

　　Functional characteristics of non negative pressure variable frequency water supply equipment:

　　1. No negative pressure

　　The equipment is directly connected to the municipal water supply network for pressurized operation, which will not cause negative pressure in the municipal water supply network and will not affect the water consumption of surrounding users.

　　2. High quality intelligent computer control

　　The system can achieve fully automatic control, with functions such as manual/automatic switching, pressure adjustment, undervoltage and phase loss protection, overload protection, overheating protection, water shortage protection, and shutdown without water. Alternatively, the human-machine interface can be configured according to user needs, allowing for visual remote adjustment, monitoring, and maintenance.

　　3. Stacked water supply

　　The equipment fully utilizes the pressure of the tap water network during operation and increases the pressure on this basis. Compared with ordinary variable frequency water supply, it can reduce the number of running pumps or lower the speed of running water pumps during operation, thus achieving energy-saving goals.

　　4. Power outage and continuous water supply

　　When there is a power outage in the power supply line, the system achieves uninterrupted water supply through bypass and other means, that is, the system automatically switches to municipal tap water pressure supply during the power outage.

　　5. Pure water quality

　　The overcurrent components are made of food grade stainless steel and other materials, which comply with national water safety regulations.

　　The box type non negative pressure device can ensure that the water stored in the water tank is automatically updated daily by the user, and the tank type non negative pressure device is replaced in real time to ensure water hygiene and safety.

　　6. Energy saving

　　The system does not have civil water storage facilities such as reservoirs, saving land area. The system has been running at a high efficiency point. It can save over 60% of energy. The municipal pipeline network has a certain pressure, and during operation, it only needs to be pressurized on the basis of the municipal pressure. The system runs fully automatically without the need for dedicated personnel to be on duty; Due to the lack of civil water storage facilities such as reservoirs and water quality treatment equipment, regular cleaning and disinfection work are avoided. Therefore, the energy-saving effect is very significant.

　　7. Protection function

　　The equipment has functions of overvoltage, undervoltage, phase loss, short circuit, overcurrent and automatic protection.
