The boiler; the engine; the condenser and air-pump; the feedpump and the economiser, are indicated by rectangles upon the diagram. The flow of heat is shown as a stream, the width of which gives the amount of heat entering and leaving each part of the plant per unit of time; the losses are shown by the many waste branches of the stream.
A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
In parts of Britain and Ireland, it was often called the parish pump. Though such community pumps are no longer common, people still used the expression parish pump to describe a place or forum where matters of local interest are discussed. [3] Because water from pitcher pumps is drawn directly from the soil, it is more prone to contamination.
Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by a chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level.
A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.
A spiral pump, sometimes called a Wirz pump or incorrectly Wirtz pump, is a low lift pump which is composed of a long piece of metal plating, which is wound into a coil and sealed at the top and back extremities so as to resemble a cylinder. The outer cavity serves as the inlet, while the inner (partial) tube serves as the outlet.
The oil and gas drilling industry uses massive semi-trailer-transported triplex pumps called mud pumps to pump drilling mud, which cools the drill bit and carries the cuttings back to the surface. [18] Drillers use triplex or even quintuplex pumps to inject water and solvents deep into shale in the extraction process called fracking. [19]
These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump
