for this purpose we are going to used PLC,HMI and VFD drives ,In our project first we should control optimum temperure with respect to speed to maintain set temperure of yarn, for controlling the speed of motor we will use VFD drives. For speed control of motor, synchronization of motor...
55. Three kinds of efficiency can be defined for a VSC: volumetric, isentropic and motor/transmission. The suction volume flow rate can be obtained from the volumetric efficiency, defined as the ratio of the refrigerant, and
wet, corrosive, hazardous location) that needs reliable and sturdy connections for motor loads in a small space. This also means that wires must be housed in a raceway to allow for extra protection against big equipment and corrosive materials. ...
Two types of drives that are best for variable speeds are a mechanical drive using a gear reducer, inverter duty motor and variable frequency drive (VFD) or a hydraulic motor and power unit with a variable pump. Today, variable speed mechanical drives have been proven to ...
Site A involved retrofitting an existing pump with a Variable Frequency Drive (VFD) to develop a system performance curve. A right-sized pump was then selected to provide the constant system flow rate of 250 gpm (15.8 lps) and achieved a significant reduction in power draw from 11.06 hp (...
