Solid Varicization Experimental Device,Inverter constant pressure water supply PLC experimental device

Features

The "frequency frequency constant pressure water supply tr--ning model" is a equipment carefully developed and developed by the company with the increasingly mature and improved technology. This model can simulate the life and fire water supply system of residential areas and high -rise buildings. The model is m--nly composed of water pumps, pressure transmitters, reservoirs, faucet and other equipment. It can complete tr--ning projects such as conventional motor frequency conversion speed, static pressure fixed value control, dynamic frequency conversion constant pressure water supply.

It can be widely used in the tr--ning device equipped with a inverter experimental hanging or with a inverter, a relay contactor tr--ning mount.
