Product introduction
The non negative pressure water supply equipment directly takes the municipal pipe network as the water source and forms a continuous and closed relay boosting water supply mode. It can automatically detect according to the actual water consumption and use pressure of the user, adjust the rotation speed (power consumption) of the motor, and make the equipment always in a high efficiency working state. It completely avoids the problems of water quality standard reduction and various water source pollution caused by the traditional secondary pressurized water supply system, completely maintains the water quality standard of municipal water source, makes full use of the pressure and heat energy of municipal water source itself, makes up the difference, and effectively and maximally plays the energy-saving effect of variable frequency speed regulation
Working principle
The water pump is connected to the water supply pipe network through the steady flow compensator, and the air in the steady flow compensator is discharged from the vacuum suppressor. When the water is full, the vacuum suppressor will automatically close. When the pressure of the tap water pipe network can meet the water pressure requirements, the microcomputer control system controls the water pump to enter the sleep state or enter the stable and pressure maintaining state from the stable pressure system, and the user's water is directly supplied from the equipment bypass pipeline; when the pressure of the tap water pipe network can not meet the water demand, the system will give the starting signal through the pressure sensor to start the pump to operate at a constant frequency and pressure. When the water is supplied by water pump, if the water volume of the water pipe network is greater than the flow of the water pump, no negative pressure water supply equipment will maintain normal water supply. During the peak period of water consumption, if the water volume of the water pipe network is less than the flow of the water pump, the water in the steady flow compensator can still supply water normally as the supplementary water source. At this time, the air enters the steady flow compensator from the vacuum suppressor, eliminating the negative pressure of the water pipe network, and the steady flow regulating tank And the pipeline does not produce negative pressure. After the peak period of water use, when the system pressure is greater than the protection value of the equipment, the tap water enters the steady flow compensator, and the equipment continues to work normally. If the water level in the regulating tank drops to no water due to the insufficient supply of tap water or the shutdown of the pipe network, the level controller will give a stop signal to protect the water pump unit. When the water comes, the water pump automatically restores the water supply. Due to the use of advanced frequency control technology, it has soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating and stall protection, signal alarm, self inspection, fault judgment and other functions under abnormal conditions. The feed water flow is also adjusted automatically according to the water consumption.

Product characteristics
1. The utility model is directly connected with the municipal pipe network and does not need to build a pool or a large-scale air pressure tank;
2. Small size, small floor area, convenient installation, simple operation and easy maintenance;
3. The water supply system is a fully sealed structure from the tap water pipe network to the user's faucet. Pollutants will not enter the system. The water body will not be in direct contact with the air. The overflow components are made of stainless steel, without secondary pollution;
4. The water pressure is stable, which will not cause the pressure fluctuation of adjacent users' pipe network;
5. Fully automatic operation, unattended;
6. The imported frequency converter can automatically detect and adjust the frequency of frequency converter according to the change of water consumption, change the rotation speed of water pump, maintain constant pressure water supply, save electricity and water;
7. With undervoltage, overvoltage, overload, overcurrent, overheating, stall prevention and other protection functions, safe and efficient;
8. The electric control adopts intelligent control system, full-automatic control, easy operation. Once the automatic control system fails, there is still a perfect manual operation system;
9. No regular cleaning, no waste of water resources, save maintenance costs;
10. Make full use of the pressure of the original water pipe network, make up the difference and save energy efficiently;
When the water consumption is in low peak period, the equipment is in shutdown state, and the municipal water source directly supplies water to the user's pipe network through the bypass system; when the water consumption is in peak period, the equipment automatically starts to supply water by frequency conversion and speed regulation.
