The composition of the equipment:  pumping unit, frequency conversion control cabinet, pressure sensor, signal processor, pipe network, the diaphragm pressure tank, pipe valve and etc


Application: 

1.  can not have noise or vibration place: hospitals, dormitories, office buildings, residential quarters, office space, etc.
2.  villas, hotels, industrial and enterprises, schools, stadiums, hot and cold water supply for stations 
3.  need costant pressure , adjust and alter instability pressure in building water 
4.  high building, need constant pressure water supply

5.  Connected on municipal pipe network tube, need non-negative Pressure water supply



 QYG Costant Pressure Tube Equipment Product Picture:


 




  Working principle::


The non-negative pressure equipment can be connected on the municipal pipe network directly, setting required pressure on frequency control cabinet, which will compare the municipal pipeline pressure with the setting value, then send the signal to PLC programmable controller through A/D module. After that, it will calculate and export frequency controller's rate singal, depends on the singal, the frequency controller will adjust the motor's speed to achieve constant pressure water supply. 



  Product advantage:

1. no negative pressure water supply

2. variable frequency constant pressure,
3. highly automated , can switch manual / automatic mode,  can set rotation timing, pressure adjustment, constant pressure, protection from overload high voltage and overload low voltage, undervoltage, protection from phase fault, protection from leakage、 overload 、 overheat 、voltage and Water shortage
4. no need to build the pool, water tower, water tank, as well do not need special room for equipment, this equipment can connect on the municipal pipe network directly
6 energy saving: soft start and soft stop, eliminate water hammer phenomenon
8 humanized design: customer can adjust the pressure they need at any times, and it's simple and clear to adjust.
