The noria supported a bucket chain which dangled down into the well. The buckets were traditionally made of wood or clay. These windmills remained in use until the 1950s, and many of the towers are still standing. Early immigrants to the New World brought with them the technology of windmills from Europe. [5]
A shadoof or shaduf, [1] well pole, well sweep, sweep, [2] swape, [3] or simply a lift [4] is a tool that is used to lift water from a well or another water source onto land or into another waterway or basin. It is highly efficient, and has been known since 3000 BCE.
Snubbing was being used to clean out large pebble, which had entered the well through a collapsed liner. While pulling out of hole, one stripping ram was not opened sufficiently and a collar on the pipe string caught on the ram. The excessive force applied to the pipe caused it to break apart, dropping the string below the failure into the well.
In the past it was done by using a shadoof, digging deeper dikes so that gravity would remove the water, by mounting leather water-filled buckets on water wheels [2] or, if nothing else, carrying water-filled buckets manually. The Archimedes' screw was also historically used to pump water out of mines. Where no dewatering techniques were ...
Other types of similar devices are grouped under the name of chain pumps. A noria in contrast uses the water power obtained from the flow of a river. The noria consists of a large undershot water-wheel whose rim is made up of a series of containers which lift water from the river to an aqueduct at the top of the wheel.
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.
A workover rig. The term workover is used to refer to any kind of oil well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing.More specifically, a workover refers to the expensive process of pulling and replacing completion or production hardware in order to extend the life of the well.
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; Mechanical or rotary lobe pump ...
