Product Introduction

Box type non negative pressure water supply equipmentIt is developed based on the combination of stainless steel water tank and variable frequency constant pressure water supply,And install control devices such as anti negative pressure, anti backflow, and anti water quality deterioration. To meet the requirements of urban water supply network, which not only does not generate negative pressure during pumping, but also has a certain capacity for regulating and storing water, and continuously stops water supply during peak periods. Using a microcomputer controlled variable frequency pump to operate at a constant speed and utilizing the existing pressure of tap water can ensure that the pressure required by the user is constant. It has the advantages of energy saving, environmental protection, low noise, and constant water supply pressure, and is currently the most advanced water supply mode.

The main technical indicators of boost pressure range, flow rate, and energy-saving indicators are all higher than other reported products in China, andThe design is innovative and the overall level has reached the leading domestic and international advanced levels, therefore, it has a great competitive advantage in the market. In summary, the main characteristics of intelligent box type non negative pressure water supply equipment are to protect pipeline pressure, regulate peak water use, save energy, be safe, environmentally friendly, provide high-quality water supply (solve secondary water supply pollution), and have low noise.

Model Meaning

Product advantages

Ensure pipeline pressure:

Adjusting peak water usage, an intelligent electric valve is used at the inlet of the water tank to control the inlet pressure and water level. When the pressure in the pipeline decreases and the booster pump draws water from the water tank, intelligent control can be used. When the water level in the tank is below a certain level, the electric valve is opened to release water from the pipeline, ensuring a certain pressure at the water intake. This measure can avoid peak water usage and have a peak shaving effect. Secondly, it avoids zero pressure discharge from ordinary water tanks and provides good protection for pipeline pressure.

Operational reliability:

When there is a peak in water usage or when the tap water is cut off, water is supplied from the water tank, greatly improving the reliability of users' water use and fully complying with self supplied water standards.

Energy saving:

When the tap water pressure can meet the user's water requirements, the booster pump is in a sleep state through frequency conversion control. When non peak water usage occurs and the tap water pressure cannot reach the user's water pressure, the water pump can add pressure boosting on top of the tap water pressure (0.2-0.5MPa), making full use of the excess pressure to save electricity and achieve significant energy-saving effects.

Highly automated:

The system can achieve fully automatic control, with functions such as manual/automatic switching, timed rotation of main and auxiliary pumps, pressure adjustment, constant voltage, high and low voltage protection, under phase protection, leakage protection, overload protection, overheating protection, water shortage protection, stopping without water, and instantaneous trip protection. Additionally, the human-machine interface can be configured according to user requirements for visual remote adjustment, monitoring, and maintenance.

hygiene:

The overcurrent components are made of food grade materials such as stainless steel, which comply with international water safety regulations.

Save investment:

No need to build large water tanks.

instructions

When the public water supply network pressure is ≤ 0.2Mpa (can be freely set to 0.2-0.4Mpa), the electric valve is closed, the booster pump is started, and water is supplied from the water tank. Conversely, when the public water supply network pressure is ≥ 0.2Mpa, the electric valve is opened and the booster pump is closed after a delay of 10 minutes (time adjustable), and water is supplied from the public water supply network. The water stored in the non negative pressure water tank is intelligently controlled to circulate every 12 hours to ensure fresh and pure water quality. The variable frequency pump of the box type non negative pressure water supply equipment operates at a certain speed, utilizing the original pressure of tap water to achieve superposition and ensure the pressure required by the user is constant. The inlet of the variable frequency pump for the non negative pressure water tank is connected to the non negative pressure steady flow tank, and the non negative pressure device is turned on and off to prevent negative pressure from being generated in the tap water network. When the pressure in the pipeline network is stable, the electric valve opens and water is directly supplied from the tap water pipeline network; When the electric contact pressure gauge detects insufficient pressure in the pipeline network, the electric valve closes, the booster pump starts, and water is supplied from the water tank. When the pipeline network reaches a certain pressure and stabilizes, the booster pump stops working, the electric valve opens, and the tap water pipeline network supplies water directly again. The booster pump and electric valve work accordingly based on the feedback from the electric contact pressure gauge. The electric valve of the tap water network automatically closes when the water is cut off, and the booster pump starts to supply water from the water tank. When the liquid level in the water tank drops to a certain level, the floating ball signal of the liquid level is transmitted to the control cabinet, and the equipment automatically stops and resumes operation when powered on.
