What is the purpose of the scavenge pump?

Scavenge pumps are found in devices which include a lubricating system. These pumps are useful to propel used oil back to an oil sump or tank under certain conditions, for instance when gravity or air pressure is not sufficient to move the used oil.

What is a lube and scavenge pump?

Gearbox-driven lubrication and scavenge pumps use gerotor technology to provide the customized, smallest, most compact, lightweight, reliable solution to distribute lubricating oil into main gas turbine engine and scavenge the oil back to the reservoir.

What does scavenge oil mean?

Scavenging oil system as a part of recirculatory oil system. The subsystem of a gas turbine engine lubrication system that collects the oil after it has lubricated the bearings and gears and returns it to the oil tank.

What is a dry sump on a car?

In a dry sump, extra oil is stored in a tank outside the engine rather than in the oil pan. There are at least two oil pumps in a dry sump — one pulls oil from the sump and sends it to the tank, and the other takes oil from the tank and sends it to lubricate the engine.

Why are scavenge pump gears larger than pressure pump gears?

The scavenge pumps are made larger than the pressure pumps, in order to ensure that they can handle this increased volume of oil/air. The argument that “keeping the sump dry is not important” is a bit of a spurious one.

What is a dry-sump on a car?

What is an oil less turbo?

The oil-less models employ a version of the TRIPLEX CERAMIC™ ball bearing system where the full complement bearings are lubricated by a high-quality channeling grease. The internal components are made of stainless steel to prevent rusting over the lifetime of the turbocharger.

Why scavenging is required?

Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing the cylinder with fresh air. Efficient scavenging is necessary for good combustion of fuel inside the engine cylinder. The passage of scavenge air will also assist cooling of the cylinder, piston and valves.

What are the importance of scavenging?

Scavengers play an important role the food web. They keep an ecosystem free of the bodies of dead animals, or carrion. Scavengers break down this organic material and recycle it into the ecosystem as nutrients.

Where are gerotor pumps used?

Gerotor pumps are widely used for different applications such as oil pumps, fuel pumps, hydraulic motors and power steering units, among others. Gerotor pumps find application in oil pumps to circulate engine oil, under pressure, to the rotating bearing and sliding pistons and the camshaft of the engine.
