Pumps are used to transfer fluid in a system, either at the same elevation or to a new height. The needed flow rate depends on the height to which the fluid is pumped. Each pump has a head- discharge relationship that is inversely proportional i.

Pumps Application In Series Or Parallel

Bench-top test set that allows students to investigate the operation and performance of a single centrifugal pump and two centrifugal pumps in both series and parallel. A compact, bench-top and fully self-contained centrifugal pump test set, that allows students to find the characteristics of centrifugal pumps, working alone or in series or parallel. The apparatus comprises two identical centrifugal pumps,together with two bearing-mounted motors driving each pump independently. The pumps draw water from the clear acrylic reservoir. The water travels through a series of valves to be delivered to a flow measurement device. The water then returns to the reservoir for re-use, keeping water use to a minimum.

HM Base module for experiments in fluid mechanics. In complex systems, pumps can be connected in series or in parallel. In series operation the heads are added together and in parallel operation, the flow rates of the pumps are added. Series and parallel configuration of pumps behave similar to series and parallel configuration of electric resistances in electric circuits. The pump correlates with the electric resistance, the flow correlates with the electric current and the head with the voltage.

Pumps in Series and Parallel

Sometimes the required operating conditions for a system are beyond the reach of a single, standard pump. Rather than purchasing a heavy duty pump that may be far more than you need, consider taking advantage of system design strategies to combine simple pump performances that add up to the necessary requirements. The following post walks you through pumps in series and in parallel so that you can get your ducks… I mean pumps… in a row — or side by side, depending on the application. Putting your centrifugal pumps in series, or connected along a single line, will let you add the head from each together and meet your high head, low flow system requirements. This is because the fluid pressure increases as the continuous flow passes through each pump, much like how a multi-stage pump works.

There may be many reasons to use parallel or series pumps instead of a single, larger Figure 5. PDF Design, operation and refurbishment of centrifugal pumps are strongly The flow system has the ability to test the pumps as a single unit or as a two pumps connected in series or parallel. Download full-text PDF. A platform for sliding vane pump and centrifugal pump tests is installed to study the series operation of them under different characteristics of pipeline. Firstly, the sliding vane pump and the centrifugal pump work independently, and the performance is recorded. Then, the two types of pumps are combined together, with the sliding vane pump acting as the feeding pump. Comparison is made between the performance of the independently working pump and the performance of series operation pump.

Pumping Systems: Parallel and Series Configurations. Two similar pumps, in series, operate in the same manner as a two-stage centrifugal pump. Each of the pumps is putting energy into the pumping fluid. Pumps in series and parallel. Part 1: Laboratory testing of pumps in series and parallel. To produce performance curves for a single pump at different impeller speeds, and fortwo identical pumps running in both parallel and series configurations. These curvesare used in matching a pump, or a set of pumps, to a particular application with arequired flow rate and pressure rise, and to determine the power required to operateeach pump.


The final example in this book combines parallel, series, and variable speed pumping for optimal energy savings. Parallel Pumping. Background. Pumps are.


What is the difference in arranging pumps in series and in parallel?

To demonstrate the basic operation and characteristic of centrifugal pumps. To differentiate the flow rate and pressure head of a single pump and of two. Pumps are used in almost all aspects of industry and engineering from feeds to reactors or distillation columns in chemical engineering to pumping storm water in civil and environmental. They are an integral part of engineering and an understanding of how they work is important for any type of engineer. Centrifugal pump is one of the most widely used pumps for transferring liquids.

Pumps can be arranged and connected in serial or parallel to provide additional head or flow rate capacity. Centrifugal pumps in series are used to overcome larger system head loss than one pump can handle alone. With a constant flowrate the combined head moves from 1 to 2 - BUT in practice the combined head and flow rate moves along the system curve to point 3. Operation of single stage pumps in series are seldom encountered - more often multistage centrifugal pumps are used.

И его ничто не омрачало. Их отношения развивались медленно и романтично: встречи украдкой, если позволяли дела, долгие прогулки по университетскому городку, чашечка капуччино у Мерлутти поздно вечером, иногда лекции и концерты. Сьюзан вдруг поняла, что стала смеяться гораздо чаще, чем раньше. Казалось, не было на свете ничего, что Дэвид не мог бы обратить в шутку. Это было радостное избавление от вечного напряжения, связанного с ее служебным положением в АНБ. В один из прохладных осенних дней они сидели на стадионе, наблюдая за тем, как футбольная команда Рутгерса громит команду Джорджтауне кого университета. - Я забыла: как называется вид спорта, которым ты увлекаешься? - спросила Сьюзан.

Она знала, что это. Как и то, что шахта лифта защищена усиленным бетоном. Сквозь клубящийся дым Сьюзан кое-как добралась до дверцы лифта, но тут же увидела, что индикатор вызова не горит. Она принялась нажимать кнопки безжизненной панели, затем, опустившись на колени, в отчаянии заколотила в дверь и тут же замерла. За дверью послышалось какое-то жужжание, словно кабина была на месте.

 - Дэвид, ты просто гений. ГЛАВА 121 - Семь минут! - оповестил техник. - Восемь рядов по восемь! - возбужденно воскликнула Сьюзан. Соши быстро печатала. Фонтейн наблюдал молча. Предпоследний щит становился все тоньше.

Могу я поинтересоваться, кто со мной говорит. - А-а… Зигмунд Шмидт, - с трудом нашелся Беккер. - Кто вам дал наш номер. - La Guia Telefonica - желтые страницы. - Да, сэр, мы внесены туда как агентство сопровождения.  - Да-да, я и ищу спутницу.  - Беккер понял, что совершил какой-то промах.

 Viste el anillo. Ты видел кольцо. Двухцветный замер. Как правильно ответить. - Viste el anillo? - настаивал обладатель жуткого голоса. Двухцветный утвердительно кивнул, убежденный, что честность - лучшая политика.

Ее тревога не была напрасной. Дэвид в опасности… или того хуже. Быть может, уже поздно.

 Может, там был кто-нибудь. - Нет. Только мы трое. Было ужасно жарко. - И вы уверены, что эта женщина - проститутка.

 Если вы вызовете службу безопасности, она умрет. Стратмор вытащил из-под ремня мобильник и набрал номер. - Ты блефуешь, Грег. - Вы этого не сделаете! - крикнул Хейл.
