Working process of variable frequency constant pressure water supply system
Working process of variable frequency constant pressure water supply system
Working process of variable frequency constant pressure water supply cycle switching control :
Inverter connect with in the first pump motor need to add pump must stop frequency inverter, and the process of output signal by output port RO1 to RO3switch to PLC controlled by PLC. At the beginning of switching, stop the output (inverter is arranged for free parking), using a water pump inertia to switch to the power frequency operation of the first pump, frequency inverter is connected to the second pumps on starting and running, according to this, the second pump is switched to power frequency operation, frequency inverter is connected to the third pumps on the start and run; to reduce pump, the first pump will be the stop, second water pumps stop, then inverter connected to the third pumps . Then need to add pump, switch to start the cycle from third water pumps. This way to ensure that there is always a water pump in the frequency operation, any of four pumps in variable frequency operation are possible. In this way, can do that no matter how change can maintain water pipe network pressure substantially constant.
Working process of variable frequency constant pressure water supply sequence control:
Inverter is connected to the first pump motor, when pump need to be added or reduced, by a inverter RO1~RO3 port output signal to start or stop other pump, then pump starting with coupling decompression starting device or a soft starter.
Shenzhen Aimike Electric Co. Ltd was founded in 2004, has a number of master inverter core technology engineers. Aimike inverter with lean quality, core technology, to produce a flux vector inverter which leading in international.Through the unremitting efforts Aimike made a major breakthrough in the field of inverter, now the latest generation of products AMK3800 series inverter using the latest current vector inverter, once widespread concern by the advent of market. The scope of application is widely,like involving industry, leading technology. Aimike believe that through the efforts we will be able to become a powerful high-tech enterprises, enterprise development also will be getting better and better.
