What is the characteristic curve of a pump?
The characteristic curve of a pump is the interaction of two variables that describe its performance: HEAD: the energy by unit of mass that the pump can supply to the fluid. FLOW RATE: the quantity of fluid that goes through a section in a certain period of time.
What is System curve of centrifugal pump?
The system curve describes the increase in head resulting from increasing fluid flow through the pipework and other equipment in your plant. The pump curve describes the relationship between the rate of fluid flow and head for the pump itself.
What do you understand by characteristic curves of a pump What is the significance of the characteristic curves?
The performance of a centrifugal pump can be shown graphically on a characteristic curve. A typical characteristic curve shows the total dynamic head, brake horsepower, efficiency, and net positive Suction head all plotted over the capacity range of the pump.
What is the working principle of centrifugal pump?
PRINCIPLE OF OPERATION OF CENTRIFUGAL PUMPS. :Working Mechanism of a Centrifugal Pump A centrifugal pump is one of the simplest pieces of equipment in any process plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped.
What is a performance analysis of a centrifugal pump?
The performance analysis of centrifugal pump is carried out after designing the dimensions of centrifugal pump. So, shock losses, impeller friction losses, volute friction losses, disk friction losses and recirculation losses of centrifugal pump are also considered in performance analysis of centrifugal pump.
What are the parts of a centrifugal pump?
Typical Centrifugal pumps vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Some of the most common components found in centrifugal pumps are: Pump main housing. Impeller. Impeller seal.
What is operating characteristics curve of pump?
The pump characteristic curve is defined as ‘the graphical representation of a particular pump’s behavior and performance under different operating conditions. Pumps come in different sizes based on their power and flow rate.
