Product details
Product Description
Details:
Constant pressure water supply system 
Flow Range:5-1500m3/h
Head Range:5-500m
Power Range:1.1-250KW
Temperature:-20ºC-110ºC
Material:Cast Iron,Stainless Steel
Work Pressure:<1.6Mpa
Products Overview: 
Constant pressure
Air pressure tank precharge pressure 2~3 bar, constant pressure pump and pressure relief valve control the pressure and keep the change range in ±0.2bar. The swelling water flow in and flow out from constant pressure through two separated expansion pipeline.
Exhausting gas
During the exhausting process, high pressure circulating water enters into atmospheric tanks and after decompression ,gas and water separated, then the precipitated gas enter into atmosphere through exhaust valve.
Supply water
The water which is lost because of exhausting gas and pipeline leakage can be monitored constantly by control unit, and once it is lower than the setting value, it will supply water automatically. The water quantity in diaphragm tank is determined by water level sensor.
Drainage
The system water enter into basic tank because its temperature increasing result in pressure is very high, and when the basic tank water quantity exceed the preset value, it automatically drainage too much water in order to guarantee the tank will not undertake pressure.
Performance Characteristics:
1.directly connected with the municipal pipeline, no reservior needed. 
2.small volume, occupies little space, convenient installation. 
3.water tank, pumps are made of stainless steel, no secondary pollution. 
4. the water pressure is steady, won't cause adjacent user pipe pressure fluctuations. 
5. automatic operation, can unattended. 
6.protection function is well-found, the fault automatically alarmed. 
7. make full use of the original water pressure, make up pressure difference, high efficiency and energy saving. 
When the municipal pipeline is high-pressure, equipment in stop condition, municipal water goes directly to the user network through the by-pass pipe. 
When the municipal pipeline is low pressure, equipment automatic starts the pump on the basis of original municipal water pressure, carries on the variable frequency speed regulation pressurization water supply.
