Reciprocating pumps are used where the delivery pressure of the fluid is quite large. In this article, we will discuss on Single-acting Reciprocating Pump. As the name itself indicates that it has a single component of the suction valve, delivery valve, suction pipe, and delivery pipe along with a single-piston. Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place. Reciprocating pumps are in use where a certain quantity of fluid mostly sump has to be transported from the lowest region to the highest region by the application of pressure.

Approved Reciprocating Pump Manufacturers. Reciprocating pumps are subject to packing leaks and in such services must be fitted with a double stuffing box to provide an enclosed leakage disposal system. In the traditional piston pump the upper valve is usually situated in the piston and known as the piston valve; the lower valve is called the foot valve. Higher viscosity oils can be delivered by reciprocating pumps operating at slower speeds, but such applications usually are not economical. He is the author, editor at themechanicalengineering.


The main difference between reciprocating and centrifugal pump are, In reciprocating pump the discharge is fluctuating and pulsating whereas the discharge is.


Description of a Reciprocating Pump

Introduction: Machines which deliver liquids with pressure are simply called pumps. Earlier we discussed mainly centrifugal pumps with water as a working fluid. In this chapter we shall decribe briefly positive displacement pumps which includes pumps using oil as working fluid. The positive displacement pump designs are as follows. Many mechanical designs are in wide use and a few of the following are shown in Fig.

Probably bcoz centrifugal pumps are continuous while reciprtocating pumps are discontinuous process. I think centrifugal pumps are used for viscous fluid such as oil,chemicals. Reciprocating can handle only pure water as it's valves cause frequent trouble. Only receprocative pumps will be used to pump high viscous fluids like chemical and oils.

Он отпил глоток кофе.  - А теперь прошу меня извинить. Мне нужно поработать. У Мидж отвисла челюсть. - Извините, сэр… Бринкерхофф уже шел к двери, но Мидж точно прилипла к месту. - Я с вами попрощался, мисс Милкен, - холодно сказал Фонтейн.

Он предоставил АНБ выбор: либо рассказать миру о ТРАНСТЕКСТЕ, либо лишиться главного банка данных. Сьюзан в ужасе смотрела на экран. Внизу угрожающе мигала команда: ВВЕДИТЕ КЛЮЧ Вглядываясь в пульсирующую надпись, она поняла. Вирус, ключ, кольцо Танкадо, изощренный шантаж… Этот ключ не имеет к алгоритму никакого отношения, это противоядие. Ключ блокирует вирус.

Тогда, кто бы ни стал обладателем ключа, он скачает себе нашу версию алгоритма.  - Стратмор помахал оружием и встал.  - Нужно найти ключ Хейла. Сьюзан замолчала. Коммандер, как всегда, прав.
