Weep hole. A weep, a weep hole, or a weep-brick is a small opening that allows water to drain from within an assembly. Weeps are located at the bottom of the object to allow for drainage; the weep hole must be sized adequately to overcome surface tension.
In cased hole completions (the majority of wells), once the completion string is in place, the final stage is to make a connection between the wellbore and the formation. This is done by running perforation guns to blast holes in the casing or liner to make a connection. Modern perforations are made using shaped explosive charges, similar to ...
Two paradigms can be used to introduce the concept to students using pressure induced by gravity or by pumps. In the version with pressure induced by gravity, large tanks of water are held up high, or are filled to differing water levels, and the potential energy of the water head is the pressure source. This is reminiscent of electrical ...
As a result, the electric motors are normally mounted above the overflow, top water level of the wet well, usually above ground level, and drive the sewage pumps through an extended vertical shaft. To protect the above ground motors from weather, small pump houses are normally built, which also incorporate the electrical switchgear and control ...
Due to the rotation, water is then picked up by the tube and pumped upwards in the hose. The coil pump, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in Asia. [1] The coil pump was built as an alternative to the Archimedean screw. Unlike the Archimedean screw ...
A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.
A grid energy storage system that pumps water uphill for later use by a hydroelectric generator plant. push switch A device that closes or opens an electrical circuit when pushed. push–pull converter A converter with two sets of primary switching elements so that the transformer primary voltage can be reversed on each cycle.
Submersible pump cables are electrical conductors designed for use in wet ground or under water, with types specialized for pump environmental conditions. [5] [6] [7] A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions.
