Approvvigionamento idrico comunitario Soluzione
Approvvigionamento idrico comunitario Soluzione
Si stima che oggi quasi un terzo della popolazione mondiale viva in aree caratterizzate da stress e scarsità idrica. Si prevede che entro il 2040 quasi il 20% dei paesi del mondo sarà sottoposto a un significativo stress idrico. Le perdite di acqua ed energia nel settore dell’approvvigionamento idrico rimangono molto elevate. In media, la rete idrica globale spreca il 40% della sua acqua a causa di irregolarità nella fornitura idrica, perdite e problemi di pressione nei tubi.
Insieme ai nostri numerosi partner, aiutiamo i clienti nel settore idrico. Le soluzioni VEICHI per il settore idrico aiutano a garantire la conformità e a contenere i costi.
Caratteristiche e vantaggi
Solution Advantages
Water conservation
From water production and distribution to wastewater pumping and treatment in all stages of the water cycle, water supply system precisely controls the flow and pressure to distribute the water reasonably, which can effectively reduce leakage in the pipeline.
Reduce energy consumption
Adopt high-efficiency motor and high-efficiency inverter to precisely adjust water supply volume and water pressure, maximizing energy utilization efficiency and reducing water supply energy consumption.
Reduce equipment impact
Inverter drives the pump from 0hz soft start, and the inverter has a variety of protection functions to avoid violent fluctuations in water pressure during operation and reduce the impact of water hammer effect on pipes and valves.
Intelligent and reliable
IOT platform can detect the operation status of pumps in real time, which is convenient for debugging and fault maintenance; it can intelligently judge the water demand according to big data and adjust the water supply volume and water pressure.
Overview
With the development of frequency converter speed control technology and people's continuous improvement of the quality requirements of drinking water, frequency conversion water supply equipment has been widely used in multi-story residential community living and high-rise buildings, which has the following advantages:
1. Low equipment investment and reliable system operation;
2. Small footprint, saving electricity and water;
3. High degree of automation, convenient operation and control, etc.
The application of the water supply industry is extremely extensive. The water supply can be controlled by road watering, household water supply, industrial water supply, construction site water supply, etc. The quality of the water supply inverter is uneven, so that our AC310 has a good entrance. The water supply plan is relatively uniform and the maintenance is more convenient.
Equipment composition and working principle of the water supply industry
1. Constant pressure water supply mainly consists of a motor, a water pump, a buffer tank, a remote pressure gauge, and an AC310 inverter. Generally use the terminal to start and stop.
2. The constant pressure water supply system compares the feedback signal of the remote pressure gauge with the given value. When the feedback value is higher than the sleep threshold, the inverter enters the sleep state after entering the sleep time. When the feedback threshold is below the start threshold, the motor is restarted to maintain the pressure near the set point.
Pump unit
Constant pressure water supply system features
1. Pump soft start, stop, no impact and overpressure hazard, no water hammer phenomenon;
2. Reliable operation: the frequency converter realizes the soft start of the pump, prevents the pipe network from impacting, avoids the pipe network pressure exceeding the limit, and the pipe is broken;
3. The equipment has high degree of automation, the water supply is stable and reliable, and the water quality has no secondary pollution;
4. Perfect protection function: a single pump fails, actively sends out alarm information, and starts the standby pump to maintain the water supply balance;
Functions to be realized in the constant pressure water supply industry
The main function of constant pressure water supply is to keep the water pressure constant without large fluctuations.
Mainly implemented features:
1) The pressure is given, that is, the given number of kilograms.
2) The sleep function is implemented, and the motor is maintained at a low speed or a zero speed when no water is used.
3) When the pressure feedback is below a certain value, it is necessary to restart the holding pressure.
Conclusion
The constant pressure water supply uses the inverter PID control function. Before the constant pressure water supply mainly uses AC60, AC70 inverter realizes the requirement of constant pressure water supply, but the control performance of AC310 inverter on constant pressure water supply is more perfect, because our company is The PID control algorithm is optimized on the AC310 universal frequency converter, which makes the PID control performance, high precision and fast dynamic response, which can achieve excellent process control and ensure the reliability of process control.
