A Rushton turbine is a type of impeller used in mixing and agitation applications, particularly in bioreactors and chemical engineering processes. It is characterized by its flat, disc-like shape that has several radial blades attached to it, typically with a high aspect ratio. The design of the Rushton turbine facilitates effective mixing and aeration of liquids, making it ideal for applications involving the mixing of liquids and gas phases.
A saqiyah, also spelled "sakiya" or "sakia," refers to a traditional water-lifting device used in many regions, particularly in the Middle East, North Africa, and parts of South Asia. It is designed to draw water from a lower source, such as a well or river, and elevate it for irrigation, drinking, or other uses.
A scoop wheel, also known as a scoop wheel pump, is a type of water lifting device or mechanical device that is used to raise water from a source, such as a well or a river, to a higher elevation. It typically consists of a circular wheel with attached scoops or buckets that can scoop up water as the wheel turns.
A screw pump is a type of positive displacement pump that is used to move fluids by using one or more helical screws to generate flow. The basic principle of operation involves the rotation of the screw(s) within a casing, which creates a series of cavities that transport the fluid from the inlet to the outlet of the pump.
A sinusoidal pump, often referred to as a sinusoidal wave pump, is a type of positive displacement pump that utilizes a sinusoidal motion to move fluids. This design allows for continuous pumping action with a smooth flow rate, as opposed to the more abrupt flow patterns seen in some other types of pumps.
The slip factor is a term used in various fields, but it is most commonly associated with fluid dynamics and aerodynamics. It refers to the difference between the theoretical performance of a pump, fan, or aerodynamic surface (like an airplane wing) and its actual performance due to losses caused by various factors. ### In Pump and Turbomachinery Context: In the context of pumps and turbines, the slip factor is defined as the ratio of the actual flow rate to the theoretical flow rate.
A slurry pump is a type of pump designed to handle the transfer of slurry, which is a mixture of solids and liquids, typically water. Slurry pumps are used in various industries, including mining, mineral processing, wastewater treatment, and chemical processing, to move abrasive and viscous fluids that contain particles such as sand, sludge, and other solids.
A solar-powered pump is a type of pump that uses energy harnessed from the sun to operate. These pumps are typically powered by solar panels that convert sunlight into electricity, which is then used to run the pump. Solar-powered pumps are commonly employed in a variety of applications, including: 1. **Irrigation**: In agriculture, solar pumps are used to move water from wells, rivers, or reservoirs for irrigation purposes, providing farmers with a sustainable solution for watering crops.
Specific pump power (SPP) is a measure used to evaluate the efficiency of a pump or a pumping system. It quantifies the power required to pump a certain volume of fluid over a given height or pressure. The specific pump power is usually expressed in units of watts per cubic meter per second (W/(m³/s)) or horsepower per gallon per minute (hp/GPM), depending on the context and the system being analyzed. ### Key Aspects of Specific Pump Power 1.
A stirrup pump is a type of manual pump commonly used for inflating items like bicycle tires and sports balls. It consists of a long vertical cylinder and a handle that pivots on a hinge, which allows the user to push and pull in a motion similar to using a stirrup. When the handle is pulled up, air is drawn into the cylinder, and when it is pushed down, the air is expelled into the item being inflated.
A submersible pump is a type of pump designed to be submerged in a liquid, typically water. It consists of a motor and a pump body that are enclosed in a single housing. Submersible pumps are used to move fluids from lower to higher elevations, and they operate by pushing the fluid to the surface rather than pulling it, which is advantageous for lifting liquids over long distances or to considerable heights.
A sump pump is a device used to remove accumulated water from a sump basin, typically found in the basement of a home or building. Its primary function is to prevent flooding and manage water levels, particularly in areas prone to groundwater buildup or excessive moisture. Here are some key points about sump pumps: 1. **Function**: The main purpose of a sump pump is to keep the basement or crawl space dry by pumping out water that collects in the sump pit.
Szczecin pumps refer to a specific type of pumping equipment or system, but it could also refer to a brand or a product associated with the city of Szczecin, Poland. Szczecin is known for various industries, including shipbuilding and maritime activities, which may involve pumps used in shipping, water management, or other industrial applications.
Thermodynamic pump testing is a method used to evaluate the performance and efficiency of pumps, specifically those used in HVAC (Heating, Ventilation, and Air Conditioning) systems, as well as in various other processes involving fluids. This testing typically involves measuring and analyzing the temperature and pressure changes that occur within the pump and the fluid it moves.
A treadle pump is a type of irrigation pump that is operated by foot, allowing the user to use their body weight to drive the pumping action. Typically, it consists of two pedals that can be alternately pressed down by the feet, which in turn moves a piston or a diaphragm that draws water from a well or a nearby water source and discharges it for irrigation purposes.
Trompe, or "trompe l'oeil," is a French term that translates to "deceive the eye." It refers to a visual art technique that uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions. Trompe l'oeil is often used in painting, mural art, and even architectural design to create illusions of space, depth, and texture.
A turbopump is a type of pump used in various applications, particularly in rocket propulsion systems, to move fluids at high pressures and flow rates. It combines a turbine and a pump into a single unit, leveraging the mechanical energy from the turbine to drive the pump. In rocket engines, turbopumps are critical components that transfer propellants (liquid fuel and oxidizers) from the tanks to the combustion chamber at high pressures.
A variable displacement pump is a type of hydraulic pump that can adjust its output flow rate and pressure based on the demands of the system it serves. Unlike a fixed displacement pump, which has a constant flow output regardless of the load, a variable displacement pump can change its displacement (the amount of fluid it displaces per revolution) to match the requirements of the hydraulic system.
Village-level operation and maintenance of pumps refers to the local management, servicing, and upkeep of water pumps within rural or village settings. These pumps are vital for accessing water for drinking, irrigation, and other domestic purposes. Effective operation and maintenance at the village level are essential for ensuring reliable water supply and sustainability of water resources.
A volute in the context of a pump refers to a spiral-shaped casing or channel that is part of the pump design, specifically in centrifugal pumps. Its primary function is to convert the velocity of the fluid exiting the impeller into pressure energy. Here's a breakdown of how a volute works: 1. **Fluid Flow**: As the impeller rotates, it imparts kinetic energy to the fluid, causing it to flow outwards from the center of the impeller.
