LOCKE no negative pressure box pumping station mainly uses water tank as the standby water source of the whole system. When the water pipe network is under pressure or no water, it will be put into operation automatically and replenish water supply, so as to ensure the stability and continuity of water supply. After the pressure recovery of tap water pipe network is automatically converted to the normal pressurized water supply mode, the water tank is automatically replenishing water, and when the water supply pressure of the tap water pipe network is normal, the memory water of the cleaning box is automatically timed to ensure the water supply quality.

LOCKE no negative pressure box pumping station is developed on the basis of combined stainless steel water tank and variable frequency constant pressure water supply, and equipped with anti negative pressure, anti backflow and water quality deterioration control devices. Compared with ordinary frequency conversion water supply equipment and no negative pressure water supply equipment, the equipment has the advantages of remarkable energy saving, low noise, less land occupation and high reliability.

 

1. When the water pressure is detected to meet the user's water pressure, the system directly supplies the water to the users through the municipal pipe network.

2. When the water pressure is lower than the water pressure of the user, the system is supplied to the user by superposition and frequency conversion.

3. When the water pressure is low and close to zero, the municipal pipe network is cut off, and the water supply is supplied to the user through the frequency conversion of the water tank.

4. In order to prevent the two pollution, the water tank is directly supplied to the user through the water tank.

 

1, save investment: save about 50% of investment, no need to build a reservoir or roof water tank, use superimposed water supply, reduce the initial input of equipment.

2, high efficiency energy saving, low operating cost: can make full use of municipal water supply pressure, how much difference, fill, do not produce negative pressure, compared with traditional water supply equipment can save 30 %-90 %. Power outages also maintain water pressure in the municipal network.

3, high intelligence, simple operation and manpower saving: the device is controlled by the automatic intelligent controller, and it is adjusted automatically according to the user's water consumption and the tap water pressure of the pipe network. And the user interface (text, digital) display, make the customer more intuitive to see the operation of the equipment.

4, environmental sanitation: the equipment is completely closed and completely eliminated the two pollution of the water source.

5, the protection function is complete: it has the perfect overload, short circuit, overvoltage, undervoltage, lack of phase, over current, short circuit, water shortage and other automatic protection functions. In abnormal conditions, it can carry out the signal alarm, self inspection, fault diagnosis and so on.

6, easy to install less convenient: the whole set of equipment only a set of water supply control cabinet, no negative pressure steady flow tank and the three parts of the pump unit, the installation is very simple and convenient.

7, prolong the service life of the equipment: it can reliably start the soft start for multiple pump sets, make the power grid and the pipe network free of impact and rotate in turn, greatly prolonging the service life of the pump and motor. The life of the equipment can be extended by more than 3 times.

 

1. Residential buildings, residential quarters and office buildings which are built, expanded and rebuilt.

2, hotels, restaurants and so on;

3, schools, troops, organs, collective dormitories and other water intensive occasions;

4, public places such as hospitals, shopping malls, exhibition centers, gymnasiums, public bathrooms, etc.

5. The urban water pressure can not meet the water requirements of the hydrant water supply system or the automatic sprinkler system.

6, large factories, pressure pumping stations, development zones and other large flow of centralized water supply;

7, the production and living water of industrial and mining enterprises;

8. All kinds of circulating water systems;

9. It is especially suitable for water supply where the water quality is very strict.
