The single-phase motor has two terminals, and it requires only two wires to power it up, and the three-phase motor has three terminals and requires three or four (including neutral) wires to operate. The power factor of a single-phase induction motor is low, compared to that of a three-phase induction motor.
AC motors, with their continuous energy changes, are ideal for industrial and residential applications. AC motors are preferred for compressor power drives, air conditioning compressors, and hydraulic, and irrigation pumps. DC motors are preferred for steel mill rolling equipment, and paper machines.
Squirrel cage induction motors are commonly used in many industrial applications. They are particularly suited for applications where the motor must maintain a constant speed, be self-starting, or there is a desire for low maintenance. These motors are commonly used in: Centrifugal pumps.
Electric Gear motors are used in applications that require high output torque and lower output shaft rotational speed, especially where space and available power are limited. This describes a wide range of common equipment applications across multiple industries.
A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.
Pumps that are designed to be submersible are placed within the reservoir of water that needs pumping out. As such, they are often used for drainage in floods, sewerage pumping, emptying ponds or even as pond filters.
A dosing pump, which is a positive displacement pump, is designed to inject a chemical or another substance into a flow of water, gas, or steam. Dosing pumps, which are typically small, provide an extremely precise flow rate for maximum control.
Industrial valves are devices that are used to regulate liquids, gases, and slurries. The flow of liquids or gases can be controlled using these valves. This can be done through pipes and other passageways by opening, closing, and partially obstructing the passageway or pipe.
