Non negative pressure variable frequency water supply equipment Box type variable frequency non negative pressure water supply equipment Variable frequency stable pressure water supply equipment Manufacturer

Description :

Non negative pressure variable frequency water supply equipmentFeatures:

　　1. No negative pressure: The system is directly connected to the municipal water supply network for water intake and pressurized operation, which will not cause negative pressure in the municipal water supply network.

　　2. Borrowing pressure (or stacking pressure): When exceeding the permitted suction pressure and flow rate, pressure can be increased on the basis of the pressure in the tap water pipeline network. Compared to drawing water from a regular reservoir, it can reduce the number of water pumps and/or lower the speed during operation to achieve energy-saving goals.

　　3. Variable frequency constant pressure: The equipment detects the outlet pressure in real time through sensors, compares the detected value with the set value, and determines the number of sets of motors and water pumps to be put into operation and the output frequency of the frequency converter (reflected in the motor and water pump speed) to achieve constant pressure by following the water consumption curve.

　　4. Noise free: Adopting modern design concepts and fully considering the environmental requirements of modern people, a dedicated frequency converter for noise reduction is selected, and noise reduction design methods are used, so the system can operate ultra quietly.

　　5. Highly automated: The system can achieve fully automatic control, with functions such as manual/automatic switching, timed 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, water leakage detection compensation, no water stop, and instant trip protection. Alternatively, the human-machine interface can be configured according to user needs, allowing for visual remote adjustment, monitoring, and maintenance.

Non negative pressure variable frequency water supply equipmentFunctional design:

　　1. According to the system control requirements, make reasonable equipment selection, programmable controller selection, parameter setting, and program design;

　　2. The variable frequency controller has self-protection and fault handling capabilities such as overcurrent, overvoltage, undervoltage, overload, short circuit, overheating, stall prevention, instantaneous power outage protection, automatic restart, automatic shutdown for low flow, and automatic control of motor temperature;

　　3. The operation and switching process of the water pump is fully automatic, with functions such as automatic fault alarm, automatic regular inspection, automatic accumulation of working time, automatic timed rotation, and automatic shutdown of the faulty pump. Soft start and soft stop are used to reduce the impact current;

　　4. Complete monitoring and control of water level, temperature difference, pressure difference, etc. in the reservoir;
