Working principle of variable frequency constant pressure water supply equipment
According to user requirements, Zhongying Water Supply first sets the water supply pressure value, and then runs it with electricity. The pressure sensor monitors the pipe network pressure and converts it into an electrical signal, which is sent to the programmable controller or microcomputer controller. After analysis and processing, the signal is transmitted to the frequency converter to control the operation of the water pump. When the water consumption increases, the output voltage and frequency increase, the pump speed increases, and the water output increases. When the water volume decreases, the pump speed decreases, reducing the water output and maintaining the set pressure value of the pipe network. When multiple pumps are running, they start each machine soft and switch from frequency conversion to power frequency until the pressure and flow meet the requirements, realizing the cyclic control of the water pump. When running at low flow rate at night, the variable frequency water pump can be used to maintain work. The variable frequency water supply pump can be stopped to maintain pressure.
Advantages of variable frequency constant pressure water supply equipment
1. Save 70% of total investment
No need to build a water tank or install a water tank Directly connected to the tap water pipeline for pressurized water supply. It can fully utilize the original pressure of tap water Reduce the size of the water pump model (the original water pump required a head of 60M) Now only 30M is needed.
2. Pure water quality
Purified tap water is directly supplied to users after being pressurized by equipment The non negative pressure diaphragm tank adopts capsules that comply with food hygiene standards Sealed connection Separate tap water from air The water source is not polluted The water quality is good, and users can drink drinking water that meets hygiene standards Adopting microcomputer frequency conversion soft start constant voltage control The water supply pressure is stable Stable water pressure.
3. Save 70% electricity
The variable frequency constant pressure water supply equipment can fully utilize the existing pressure of the tap water pipeline How much is the difference How much to supplement When the tap water meets the requirements The device stops working The energy-saving effect is extremely significant. Up to 20% -60% or more For example, a certain residential area has a building height of 6 floors During peak water usage periods, tap water can be supplied to the 4th floor During the low peak period, water can be supplied to the 6th floor So use this device to pressurize floors 5-6 during peak water usage periods During the low peak period of water usage, the equipment goes into sleep mode (stops working). Power outages can restore normal pressure water supply to tap water. This water supply method consumes less energy The operating cost of the equipment is low Using economy Save daily electricity expenses.
4. Save land Save installation time
No need to build a pool No need to install a water tank, the complete set of equipment leaves the factory After arriving at the scene The user's tap water inlet and outlet pipes can be directly connected to the equipment Construction is simple Short construction period and small footprint.
5. Save manpower material resources
The use of variable frequency constant pressure water supply equipment does not cause water pollution No need to install disinfection equipment Further save investment. Very economical to use Due to the lack of a pool or water tank Saved regular cleaning The cost of disinfection.
6. Low noise
Due to the fact that the water pump is directly connected to tap water through a non negative pressure tank So there is no loud water rushing sound when tap water enters; The system adopts our company's SFL (synchronous low-speed life specific) pump Greatly reduce the noise caused by the operation of the water pump.
Application scope of variable frequency constant pressure water supply equipment
1. Newly built residential communities, villas, office buildings, and comprehensive buildings provide living water supply.
2. Domestic water supply for high-rise buildings, fire water, hotels, restaurants, etc.
3. Renovation of traditional water supply systems such as pressurized water supply and ground water tank pressurization.
4. Various boiler cold water supply systems and boiler hot water.
5. The intermediate booster pump station of the water plant and the secondary boosting of tap water.
6. The production, domestic water supply, and pipeline network stabilization of various industrial and mining enterprises.
7. Various types of circulating water and cooling water supply systems.
