What is a pump characteristic curve?

What is a pump characteristic curve?

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 are the characteristic curves of centrifugal pump?

Curves relating total head, efficiency, power, and net positive suction head required (NPSHR) to discharge or pump capacity (Q) are utilized to describe the operating properties (characteristics) of a pump. This set of four curves is known as the pump characteristic curves or pump performance curves.

What is centrifugal pump explain?

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. The action of the impeller increases the fluid’s velocity and pressure and also directs it towards the pump outlet.

Which among the following is not a characteristic curve for centrifugal pump?

Which among the following is not a characteristic curve for centrifugal pump? Explanation: The primary objective of a centrifugal pump is to transfer energy. Centrifugal pump is a turbomachinery. Transfer speed vs Transfer pressure is not considered as a correct characteristic curve.

What is a centrifugal pump describe the principle and working of a centrifugal pump with a neat sketch?

A Pump is generally used to induce flow or raise the pressure of a liquid. Centrifugal pumps are a category of Dynamic pumps. The working principle of centrifugal pumps involves imparting energy to the liquid by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes.

Which of the curve is used in the design of volute casing of centrifugal pump?

Answer: (a) Q-η curve, (b) Q-H curve, and (c) Q-P shaft curve. As is indicated in Figure 6(a) and Table 3, the highest efficiency is reached when volute cross-section shape is round, and the second highest cross-section shape is horseshoe shaped which is 1.05\% lower than that of round-shaped cross-section.

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.
