XYG non negative pressure frequency conversion water supply equipment ★ , summary
Tap water continuously enters the steady flow tank, and the air in the steady flow tank is discharged through vacuum suppression
When the tank is full of water, The vacuum suppressor automatically closes to prevent overflow, and then the pressure in the tank increases
When the inlet pressure sensor detects that the pressure in the tank meets the user's pressure, the equipment water pump does not start, and the tap water is supplied to the user through the bypass pipe; When the inlet pressure sensor detects that the pressure in the tank cannot meet the user's use pressure, the water pump starts frequency conversion operation, and the intelligent control system calculates and compares the user's pipe network pressure and the set pressure of the water pump in real time
If the user's pipe network pressure is higher than the user's required pressure, the output frequency will be automatically reduced, so as to reduce the speed of the water pump and the water output, If the pressure of the user's pipe network is lower than the pressure required by the user, the output frequency will be automatically increased, so as to increase the speed and water output of the water pump
When the operation of one pump can not meet the needs of the user, each water pump will start operation in turn
When the water inlet pressure sensor detects that the pressure in the tank reaches the limited pressure specified by the water company, the equipment water pump stops running to ensure that the water pipe network does not produce negative pressure
When the user's water consumption is higher than the equipment water supply, the pressure in the tank is momentarily lower than one atmospheric pressure, and the vacuum controller opens automatically to make the gas enter the steady flow tank and eliminate the negative pressure

★ Functional characteristics of frequency conversion water supply equipment without negative pressure
1、 No negative pressure
◆ the system is directly connected with the municipal water pipe network for water intake and pressurized operation, which will not cause negative pressure in the municipal water pipe network
◆ high quality intelligent computer control
◆ special purpose, self-developed, with diversified functions, can provide cutting-edge precision control, and has reached the world leading level
2、 Borrow pressure (or stack pressure)
◆ during the operation of the equipment, with the help of the pressure of the municipal water pipe network and pressurization on this basis, the number of pumps can be reduced or the rotating speed can be reduced to achieve the purpose of energy saving compared with the water absorption from the ordinary reservoir
3、 Maintain constant pressure
◆ the non negative pressure water supply equipment detects the outlet pressure through the pressure sensor in real time, compares the detected value with the set value, and determines the input number of motors and pumps and the output frequency of frequency converter (reflected as the speed of motors and pumps), so as to realize the purpose of constant pressure water supply
4、 Power failure and continuous water supply
◆ in case of power failure of the power supply line, the system realizes continuous water supply through the bypass pipeline, that is, in case of power failure, the system automatically switches the municipal tap water pressure water supply
5
Highly automated
◆ the system can realize full-automatic control and has the functions of manual / automatic switching, regular 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, pump shutdown without water, instantaneous tripping protection, etc
In addition, the man-machine interface can be configured according to the user's needs for visual remote adjustment, detection and maintenance
5、 hygiene
◆ the overflow parts are made of stainless steel food grade materials, which comply with international water related hygiene standards
6、 Save investment
◆ the system has no civil water storage facilities such as reservoir, which saves the floor area and reduces the building load, so the investment cost is greatly reduced
7、 Save operating costs
◆ the system ensures the constant pressure of the pipeline by adjusting the number of water pumps and operation speed according to the change of water consumption
When the water consumption is large, the input power is large, when the water consumption is small, the input power is small, and when the water consumption is small (such as at night), the system is supplied with constant pressure water by frequency conversion and speed regulation of a small power pump
The system has been operating at a high efficiency point
Therefore, the operation cost is greatly reduced
More than 60% of energy can be saved
◆ if the municipal pipe network has a certain pressure, it only needs to supplement the pressure on the basis of the municipal pressure during operation
Compared with the traditional water supply equipment with reservoir, it achieves the same effect and absorbs less power from the power grid
The energy-saving effect is very remarkable
◆ there is no need for special personnel to be on duty for the full-automatic operation of the system
Due to the lack of civil water storage facilities such as reservoir and water quality treatment instruments, there is no need for regular cleaning and disinfection
Therefore, the operation cost is further reduced
