No negative pressure water supply system
No negative pressure water supply system The modern and up-to-date technology adopted by the non-negative pressure water supply system realizes the on-demand supply and demand of water supply through frequency conversion. That is, how much supply the user needs, to meet the low peak and peak water supply of different water cycles, while ensuring sufficient requirements for the user's water volume. Therefore, under the premise of ensuring the demand for water supply, the user's sufficient water use effect can be satisfied....

The modern and up-to-date technology adopted by the non-negative pressure water supply system realizes the on-demand supply and demand of water supply through frequency conversion. That is, how much supply the user needs, to meet the low peak and peak water supply of different water cycles, while ensuring sufficient requirements for the user's water volume. Therefore, under the premise of ensuring the demand for water supply, the user's sufficient water use effect can be satisfied.


The non-negative pressure water supply system has small impact on the power grid and perfect protection function. The intelligent non-negative pressure water supply complete equipment adopts PLC to control multiple pump circulating soft start modes, which eliminates the impact and interference to the power grid when the pump motor is directly started, and the equipment control system has short circuit, over current, over voltage, overload, Under-pressure, phase loss, overheating and other protection functions greatly improve work efficiency and extend the service life of the pump.

The non-negative pressure water supply system control system adopts the man-machine interface touch panel operation, and the setting parameters are flexible and convenient. The control panel of the control cabinet is equipped with a human-machine interface display (touch display). On the human-machine interface, the working pressure, frequency lower limit, acceleration time, deceleration time, pump change time, pressure sensor range, etc. can be flexibly set by touch buttons. The working parameters can display parameters such as system time, system pressure, set pressure, working status of each pump, and can check various fault causes and treatment methods in the man-machine interface.

The non-negative pressure water supply system adopts the dual-insurance control mode of microcomputer intelligent and automatic emergency detection. Each pump is equipped with independent frequency converter or soft starter to form multi-channel control, which makes the frequency conversion speed regulation water supply equipment extremely reliable. .

The non-negative pressure water supply system adopts the stabilized voltage tank energy storage and the frequency conversion speed regulation technology, and the automatic speed regulation double energy saving.

The non-negative pressure water supply system adopts modern electronic technology, and the combination of microcomputer control and detection and sensing technology makes the product function perfect and the performance is excellent. The main control intelligent automation, electromechanical integration, voltage regulator tank voltage regulator system, the frequency conversion speed regulation water supply equipment is set in the full flow range of constant pressure and variable pressure water supply, with water from suction, filtration, aeration function. In the very state of the fault, the protection alarm, the language display function.

No negative pressure water supply system economy: less investment, low transportation costs, small footprint, optimized mechatronic design can save installation costs.

The pumps and valves that are not equipped with the negative pressure water supply system are all domestic high-quality brand-name products, which can ensure the reliable operation of the equipment. It meets the current sanitary standards for drinking water and plays a decisive role in today's drinking water safety projects.


In addition to the centralized water supply (including the unit's own drinking water) and secondary water supply, the drinking water sanitation standard can also be used for rural decentralized water supply. At present, as the economic, cultural and health knowledge of residents continues to increase, the demand for drinking water quality standards is gradually increasing. Although there are differences in urban and rural areas in terms of sanitary conditions, rural drinking water sanitation is also improving. Rural water quality improvement work also urgently requires health standards to be followed. Due to the complexity of rural decentralized water supply, it can be treated differently according to specific conditions, and there is flexibility in implementation.
