220V Single Phase Motor Speed controller for Water Pump
A pump is a machine or device for raising, transferring, or compressing fluids. Pumps represent the largest single use of power in industry (31%) by motor driven equipment. Process variables, including pressure and flow of gases and liquids, have long been regulated using mechanical clutches, throttles, and adjustable inlet guide vanes. Pumps often operate as a variable torque load, a load that increases as the speed increases. These mechanisms waste energy, require frequent maintenance, and provide inaccurate control.
Pumps have two main categories:
1.Positive displacement pumps force a fixed volume of fluid from inlet to discharge with each stroke or rotation. (e.g., reciprocating, rotary, or screw type pumps)
2. Centrifugal pumps are the biggest class of pumps, which use the fluid's own momentum to build up pressure or head. Centrifugal pumps use centrifugal and hydrodynamic forces to create pressure that moves the fluid from inlet to discharge.
Pumps can also be classified by principle of operation and drive requirements.

Tips:
Avariable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
