Product Name: ESWG Non Negative Pressure Variable Frequency Water Supply Equipment
Product Introduction
The working principle of ESWG type non negative pressure variable frequency water supply equipment: The variable frequency constant pressure water supply equipment is a stacked pressure water supply method that directly utilizes the pressure of the tap water pipe network, which is hygienic, energy-saving, and has low comprehensive investment. After installation and debugging, the water in the tap water network first enters the steady flow tank, and the air inside the tank is automatically eliminated through a vacuum eliminator. When installed in
non-negative pressureVariable frequency water supply equipmentWhen the pressure sensor at the outlet detects that the pressure in the tap water network meets the water supply requirements, the system supplies water directly without passing through the booster pump; When the pressure of the tap water network cannot meet the water supply requirements, the pressure difference is detected, and the difference is determined by the pressure pump and the amount to be replenished; When the water supply in the tap water network is insufficient, air enters the stabilizing tank through the vacuum eliminator to break the vacuum inside the tank, and the water supply in the stabilizing tank can be automatically extracted without generating negative pressure in the network.
Product Features
1. The non negative pressure variable frequency water supply equipment system is directly connected to the municipal tap water pipe network for water intake and pressurized operation, which will not cause negative pressure in the municipal tap water pipe network. High quality intelligent computer control, specially developed independently, with diverse functions, capable of providing cutting-edge precision control, has reached an advanced level.
2. When the borrowing (or stacking) equipment operates, it relies on the pressure of the municipal water supply network and increases the pressure on this basis. Compared with drawing water from ordinary water storage tanks, it can reduce the number of pumps or lower the speed during operation to achieve energy-saving goals.
3. Maintain constant pressure - The pressure equipment detects the outlet pressure in real time through a pressure sensor, compares the detected value with the set value, and determines the number of motors and pumps to be put into operation and the output frequency of the frequency converter (reflected as the motor and pump speed), in order to achieve the purpose of constant pressure water supply.
4. Power outage without water supply - When the power supply line is cut off, the system achieves power outage without water supply through pipeline pressure and bypass measures, that is, the system automatically switches to municipal tap water pressure supply during power outage.
5. The highly automated 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, no water parking, instant trip protection, etc. Alternatively, the human-machine interface can be configured according to user needs, allowing for visual remote adjustment, monitoring, and maintenance.
6. The hygiene and overcurrent components are made of food grade materials such as stainless steel, which comply with international water safety regulations.
7. Save investment - The system does not have civil water storage facilities such as reservoirs, saving land area and reducing building load capacity, thus greatly reducing investment costs.
8. Save operating costs - The system ensures constant pressure in the pipeline by adjusting the number of units and operating speed according to changes in water consumption. When the water consumption is high, the input power is high, and when the water consumption is low, the input power is low. When the water consumption is low (such as at night), the system is supplied with a low-power pump with variable frequency speed regulation and constant pressure water supply. The system has been running at a high efficiency point. Therefore, it greatly reduces operating costs. It can save over 60% of energy. If there is a certain pressure in the municipal pipeline network, the operation only needs to supplement the pressure on the basis of the municipal pressure. Compared to traditional water supply equipment with reservoirs, it achieves the same effect with less power drawn from the power grid. The effect is very significant. The system operates fully automatically without the need for dedicated personnel to be on duty: and due to the lack of civil water storage facilities such as reservoirs, as well as water quality treatment instruments, regular cleaning, disinfection, and other work are eliminated. Therefore, it further reduces operating costs.
