A screw pump is a device for pumping fluids or finely divided solids by use of a moving inclined plane (a screw). Picture a long screw of uniform diameter that is slipped into a closely fitting jacket or pipe. By turning the screw in the right direction, material which is pooled or clustered around the bottom can be lifted. The device was known to ancients and was used to lift water. Archimedes' screw is just this kind of device, but its history certainly dates further back, and perhaps as much as 400 more years to the time of the Assyrians (as in Hanging Gardens of Babylon). It is used today to move many kinds of fluids, and is very common in the movement of grain (where it's called an auger) and other solids that come in the form of small pieces or units. A snow blower or cement truck represent an application of the screw pump.

When was the screw pump invented?
It can take the name of Archimedes Screw as he was one of the first to introduce the idea.Archimedes lived 287 BC to 212 BCAn animation can be seen at the link below.
What is eccentric load?
Eccentric loading does not vary with different materials. Eccentric loading refers to compressive or tensile loads that do not act through the centroid of a section. Some materials may work better structurally when loaded eccentrically, but the phrase 'eccentric loading for concrete' does not make much sense.
What is the difference between helical gear and screw?
Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.Helical gears are stronger than spur gears.
Comparison between centrifugal pump and gear pump?
both gear pump and reciprocating pumps are positive displacement pumps.but the different is gear pump rotary type.reciprocating pump moves liner motion.the piston moves up and down in straight line.
Why concentric reducer is used in pump discharge?
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
What is the function of an eccentric pipe reducer in the suction side of a pump?
if we use concentric reducer at suction of pipe ,due to high turbulence flow of fluid ,some vapour pressure generate which generate bad effects on impeller of pump ,which decrease pump efficiency , so to avoid this problem the eccentric reducer's use in pump suction
What is usage of concentric and eccentric pipe reducer?
An eccentric reducer is mostly used to force air in a direction, normally towards a pump or airvalve so that it does not get trapped inside the pipework.

How do you adjust the injection pump on a 3406 cat engine?
You can adjust the injection pump on your 3406 Caterpillar engine by turning the adjustment screw on the top of the fuel pump. The adjustment screw controls how much fuel the pump sense to the engine.

What is triple screw pump?
A triple screw pump is a type of positive displacement pump that uses three screws (one power screw and two idler screws) to move fluid through the pump. This design provides smooth and pulseless flow, making it ideal for high-pressure and high-viscosity applications where precision and reliability are crucial. Triple screw pumps are commonly used in industries such as oil and gas, marine, and chemical processing.
1976 ford pick up with new fuel pump will not pump fuel why?
The mechanical fuel pump on this vehicle has an arm that fits into the front housing on the engine, and is "pumped" by an eccentric that bolts to the end of the camshaft and timing gear set. If I am not mistaken, depending on the series of engine that you have, the arm can be two different lengths or the eccentric might have come off the dowell pin that it locates itself on.
How do you bleed case 1594 injector pump?
To bleed a Case 1594 injector pump, first, ensure the fuel tank is filled with clean diesel fuel. Next, locate the bleed screw on the injector pump, typically found on the top or side. Loosen the bleed screw slightly and manually pump the fuel lift pump until fuel starts to flow without air bubbles, then tighten the screw. Finally, crank the engine to ensure it starts smoothly and check for any leaks around the bleed screw.
