1、 Overview
Energy conservation and emission reduction are currently popular trends in China. On the basis of variable frequency constant pressure water supply equipment, non negative pressure water supply equipment has emerged. Non negative pressure water supply equipment utilizes the original pressure energy of the tap water network. Under the same water supply demand, relatively small power pumps and control equipment can be selected. At the same time, in the case of low flow water use at night, tap water pressure can be used to directly supply water without starting the pump. Compared to traditional water supply equipment with water tanks, it can save electricity operating costs and investment costs. Non negative pressure water supply equipment does not require the construction of water tanks or reservoirs, occupying relatively less space, saving initial investment in equipment and the cost of flushing and disinfecting water tanks. The non negative pressure water supply equipment is a closed structure.
2、 Characteristics
1. Advanced technology: Integrating multiple technologies such as vacuum suppression, fluid control, and intelligent frequency conversion, directly connected in series with the tap water pipeline network, to achieve stable voltage, energy conservation, hygiene, safe and reliable operation, without generating negative pressure, and without the need to build water tanks or reservoirs.
2. Sanitary and pollution-free: The equipment is a fully sealed structure, and bacteria and dust will not enter the system; Avoiding the growth of algae and preventing secondary pollution and water quality pollution in the supply.
3. Significant energy-saving effect: The fully enclosed structure operation avoids phenomena such as seepage, running, emitting, dripping, and leaking, without water tanks or pools, saving disinfection and flushing water. Directly connected to the tap water pipeline network can fully utilize the original pressure of tap water, and make up for the difference as much as possible. When the tap water meets the requirements, the equipment will stop working. Non negative pressure water supply equipment operates most of the time at lower frequencies and consumes less power. Adopting frequency conversion technology to further save energy.
4. Reliable operation: It has no impact on the tap water pipeline network, and the equipment uses a regulating tank to automatically adjust without negative pressure. When the pipeline network is pressurized for water supply, it will not generate negative pressure on the original pipeline network and will not affect the normal water use of other users.
5. Investment savings: No need to build reservoirs or water tanks, saving on civil engineering investment; No need to apply pressure from zero, therefore equipment selection is relatively small and equipment investment is reduced; The water quality is pollution-free and does not require purification equipment, saving investment. It can fully utilize the pressure of the tap water pipeline network, with low energy consumption and saving daily electricity expenses.
6. Flexible electrical configuration of equipment: The electrical control part can adopt variable frequency constant voltage control.
3、 Operating environment
1. Environmental temperature: 5-50 ℃; Relative humidity: ≤ 90%.
2. The surrounding air is free from significant pollution such as corrosive gases, water vapor, dust, etc.
4、 Function and Features
1. Two working modes
3. Water level protection function, when the water level in the water tank is lower than the set water level, the system automatically protects and shuts down, and the performance of the liquid level controller is stable and reliable.
4. Automatic reset function, the system automatically starts when the power is restored after a power outage or when the water level is restored.
5. Fault pump shielding function, after the fault pump is shielded, it will directly exit the operating program and be replaced by a backup pump.
6. Automatic protection function: It has automatic protection functions such as overload, overcurrent, short circuit, phase loss, overvoltage, undervoltage, and water shortage shutdown.

4、 Function and Features
1. Two working modes
- Automatic working mode: Automatic mode is a working mode under normal water supply conditions. Generally speaking, when the customer selects this method after normal water supply, all different water supply requirements of the pipeline network will be adapted to various functions under the effective control of the non negative pressure water supply equipment when working in automatic mode.
- Manual working mode: This operation mode is set for emergency use by users in case of automatic working mode failure. It adopts a relatively simple starting method, which directly starts and stops any water pump motor on the operation panel. Generally, it is only used in case of automatic failure or debugging.
3. Water level protection function, when the water level in the water tank is lower than the set water level, the system automatically protects and shuts down, and the performance of the liquid level controller is stable and reliable.
4. Automatic reset function, the system automatically starts when the power is restored after a power outage or when the water level is restored.
