Introduction to the functions of stainless steel non negative pressure variable frequency water supply equipment

The WII (I) type three tank non negative pressure water supply equipment consists of a comprehensive hydraulic control unit, a booster pump group, a constant pressure tank body, a high pressure tank body, an ultra-high pressure tank body, an energy storage booster unit, an intelligent control cabinet, etc; It can be directly connected to the water supply pipeline network, and the equipment can fully utilize the pressure of the municipal pipeline network and ensure that the municipal water supply pipeline network does not generate negative pressure. At the same time, it can achieve compensation flow and small flow pressure maintenance functions through the cooperation of high-pressure tanks and ultra-high pressure tanks; Using the internet to connect real-world water supply equipment, after-sales teams, advanced sensors, controllers, and software applications in a novel way; Based on physical analysis, predictive algorithms, automation and electrical engineering, and other related professional knowledge, analyze the operation mode of water supply equipment and water supply network. Establish real-time connections between after-sales teams, production departments, and R&D teams through software to support more intelligent design, operation, maintenance, as well as high-quality service and fault warning, safety assurance functions.

Altitude: not exceeding 1000m. If exceeded, adjust the control components accordingly;
The installation location of the equipment should be free of conductive or explosive dust, corrosive metals, gases or vapors that damage insulation, and other media. The ZWX (III) type box type non negative pressure water supply equipment consists of a voltage stabilization compensation adjustment unit, an intelligent closed water tank, a boosting system (water tank boosting pump, boosting main pump), an intelligent control cabinet, and pipeline valve accessories; It can be directly connected to the water supply pipeline network, and the equipment can fully utilize the pressure of the SHIZHEN pipeline network and ensure that the SHIZHEN water supply pipeline network does not generate negative pressure. At the same time, it can cooperate with the voltage stabilization compensation system and intelligent closed water tank to achieve instantaneous compensation of peak voltage stabilization compensation system, intelligent closed water tank compensation and small flow pressure maintenance function; The intelligent control cabinet utilizes a universal network to integrate real-world water supply equipment, after-sales teams, and advanced technology in a novel way

Stainless steel non negative pressure variable frequency water supply equipmentFunctional characteristics;

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, in automatic mode, all different water supply requirements of the pipeline network will be adapted to various functions under the control of non negative pressure water supply equipment.

Manual working mode: This operation mode is set for emergency use by users in case of automatic working mode failure. It adopts a 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.

2. Easy to integrate into intelligent management systems, the main components use components, and the entire system has high reliability and anti-interference ability. Its built-in standard serial communication port (RS485) makes communication between the system and the computer very convenient.

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. Performance of liquid level controller.

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.
