Centrifugal Pump Performance Characteristics for Domestic Application

MATEC Web of Conferences

Water pressure problems at home can be quite frustrating in daily life which is comes in different ways of complication. It may take forever for the faucets to fill a bathtub, or a slow spray shower head and longer time taken for the washing machine to run a cycle. The problem can be fixed by installing a pressure booster pump. This research is embarked to study on a centrifugal pump performance with a view to analyse pressure built-up and flowrate in pipe at fixed speed. A simple and inexpensive test rig is developed to resemble water distribution for domestic use; i.e. house application. The method is then experimentally validated to measured and analysed the pump performance such as water pressure, water flowrate, power of pump and pump speed. Since the centrifugal pump are added, the pump is able to boost the water flowrate. However, since the centrifugal pump work at constant speed, the water pressure in pipe is high when the water demand is low. The maximum pressure inside the pipe was 28.24 psi which quite high and exceed the piping standards. Power consumption also remained constant approximately 0.500 kWh when water demand was low which led to energy wastage.

Experimental study on performance characteristics of a small centrifugal pump

2018

Article Type: Full Length Research Article A study on performance characteristics of a centrifugal pump was carried out in the hydraulic laboratory. A half horse power (hp) motor driven centrifugal pump was used. The performance characteristics of the centrifugal pump was tested under varying proportions of suction and delivery lifts for a wide range of total lifts. The pump was operated for a total lifts of 2.00, 4.00, 5.50 and 7.40 m. The results obtained reveal that for a given total lift, the efficiencies of the pump varied with the different ratios between suction and delivery lifts. For the total lift of 2.00 m, both the efficiency and discharge decreased with the increase of suction lift. For the total lifts of 4.00, 5.50 and 7.40 m, the maximum pump efficiency was obtained when the suction lift was at or around 2.00 m. This suggests that the pump operates more efficiently when the suction lift was at about 2.00 m, irrespective of delivery lift. The study results also showed ...

Parameters Affecting Efficiency of Centrifugal Pump - A Review

International Journal of Scientific Research in Science and Technology, 2021

The pump is used as one of the most significant components in chemical industry so without its existence process may not be completed, because for any fluid to flow, initial driving force is required and it is fulfilled by the pump by consuming electrical energy and converting it to pressure energy. So, the selection of pump is very important in every field of section, depending on the property of process fluid. The Centrifugal pump is most demanding nowadays because it has simple design, less maintenance, can handle large quantities of fluids, and provides very high flow rates. The Centrifugal pump has mainly two components rotating components and stationary components. Shaft and impeller (open, semi-enclosed, and fully-enclosed) comes under the category of rotating components and casing (Volute, Vortex, and circular) comes under stationary components. Various parameters of process fluid like liquid viscosity, temperature, specific gravity, vapor pressure, concentration, shear sensitive and abrasive or non-abrasive, MOC, pump environment, pressure, flow rate, etc. are calculated to gain the desired efficiency and prevent a problem like cavitation if not properly handled. In this paper, a single-stage centrifugal pump is reviewed and studied how to increase performance and efficiency of centrifugal pump.

Experimental Investigation of Centrifugal Pump Characteristics

International Journal of Advanced Natural Sciences and Engineering Researches

The pumps are divided into two main groups as positive displacement namely volumetric pumps and dynamic i.e. centrifugal pumps. Volumetric pumps are generally used to transport hydraulic oils, while centrifugal pumps are used to transport clean or dirty water. Pumps are the tools that are used to move liquid fluids from one place to another in many areas like as cars, industry, construction sites, agriculture, and homes. Therefore, determination of the hydraulic pump’s characteristics under various working conditions, including manometric head, overall efficiency, specific speed, and net positive suction head, is crucial for development, operational limitations, and durability. Experimental investigation is a more realistic method, although it is possible to determine the hydraulic pump characteristics by means of mathematical methods. Therefore, an experimental investigation is performed for the determination of the centrifugal pump characteristics in this study by using an experim...

Design and Construction of a Centrifugal Pump Test Bed

2022

This project work details the design, manufacture, and testing of a centrifugal pump. The centrifugal pump is driven by an electric motor, which is also linked to a tachometer, a variable frequency drive and a wattmeter, which measure the speed of the motor shafts and the electrical power of the pump, respectively. The driven centrifugal pump pulls fluid (water) from a sump reservoir and transfers it to a tank through a flow control valve. We were able to conduct the experiments required to completely describe a centrifugal pump using the demonstration unit. The correlations between the different parameters, such as head (H), efficiency (η), rotational speed (ω), and input power (Pi), and the flow rate (Q), were also generated in tabular and graphical form. The experimental findings acquired at the conclusion of this study demonstrate that the tested pump can achieve a head (Hₘₐₓ) of 35m, a volumetric discharge (Qₘₐₓ) of 35l/min, and a speed of 2850 rpm with an input power of 0.5HP....

Analysis on Centrifugal Pump Performance in Single, Serial, and Parallel

Journal of Energy, Mechanical, Material and Manufacturing Engineering

The pump is a tool to provide the mechanical energy to the liquid in the pump constant fluid density and large. In terms of mechanism, the pump is divided into three types, namely, rotary pumps, pump the shaft/piston and centrifugal pumps. The use of the pump are the most widely used either in the household or in the environment industry. In the centrifugal pumps, there are losses – losses among other head losses. To find the head losses among other data needs head on the pump, the pump and the discharge flow rate of the pump. Head is defined as energy per unit weight of the fluid. The head of the unit (H) meters or feet is fluid. In the pump, the head is measured by calculating the difference between the total pressure of the suction pipe and the pipe press, when measurement is done at the same height. For single full pump openings 0,00246 m³ \ s, valve openings ¾ 0,00210 and aperture of ½ 0,00177 m³ \ s can be concluded the discharge of water at the pump the larger the opening of ...
