Which motor is used in centrifugal pumps?
What Does a Centrifugal Pump Look Like? Centrifugal pumps come in many shapes, colours and sizes but they typically look something like this. The pumps consist of two main parts, the pump and the motor. The motor is an electrical induction motor which allows us to convert electrical energy into mechanical energy.
Which motor can be used for pumps?
The motor used to drive the pump is typically a three-phase, squirrel cage induction motor, with a nameplate power rating in the range 7.5 kW to 560 kW (at 60 Hz).
How do I choose a pump motor?
When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.
Is dc series motor is used in centrifugal pump?
The various applications of DC shunt motor are in Lathe Machines, Centrifugal Pumps, Fans, Blowers, Conveyors, Lifts, Weaving Machine, Spinning machines, etc.
What is the main function of centrifugal pump?
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.
Where is centrifugal pump used?
Centrifugal pumps are commonly used for pumping water, solvents, organics, oils, acids, bases and any ‘thin’ liquids in both industrial, agricultural and domestic applications. In fact, there is a design of centrifugal pump suitable for virtually any application involving low viscosity fluids.
What are three different types of water pumps?
Positive displacement, Centrifugal and axial-flow pumps are the three basic types of pumps.
What is the difference between motor and pump?
Pump is a mechanical device used to raise or move fluids using suction or pressure. … Motor is an electro-mechanical device that converts electrical energy into mechanical energy.
What is the principle of pumps?
The operating principle of the pump is to convert mechanical energy to pressure. In operation, a rotating impeller accelerates a liquid and as the area of the pump casing expands the velocity of the fluid is converted to pressure. As a result pressurized fluid exits the pump discharge.
How do you select a motor kw for a pump?
Pump Hydraulic Power (ph) = (D x Q x H x9.
Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9. 87)/1000 =3KW. Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80% = 4KW. Required Motor Size: ps / me =4 / 90% = 4.5 KW.
Which motor is used in rolling mills?
1. DC Series Motor. Since it has high starting torque and variable speed, it is used for heavy duty applications such as electric locomotives, steel rolling mills, hoists, lifts and cranes.
Can you deadhead a centrifugal pump?
You can deadhead a centrifugal pump if you operate it full of liquid with the inlet and outlet valves closed, so there is no flow through the pump. In this case, the rotating component of the pump (impeller) will continue to agitate the same volume of liquid.
Which DC motor has maximum self loading property?
Which DC motor has got maximum self-loading property? Explanation: A differentially compound DC motor, flux reduces so sharply at small increase in load at higher values of load.
Why is the DC motor preferred over AC motor?
AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.
Which power is mentioned on a name plate of a motor?
Which power is mentioned on a name plate of a motor? Explanation: Name plate of the motor shows rated values i.e. rated speed, rated current, rated voltage. It also shows output power available at shaft when all other quantities are set to rated values.
