voitelupumpputyyppejä

Voitelupumpputyyppejä refers to different designs of pumps used in lubrication systems. These pumps are essential for circulating oil or other lubricants to reduce friction and wear between moving parts in machinery. The choice of pump type depends on factors such as the required flow rate, pressure, viscosity of the lubricant, and the operating environment.

One common type is the gear pump. Gear pumps use meshing gears to displace lubricant. As the gears rotate, they create expanding cavities on the inlet side that draw in oil, and then reduce the volume on the outlet side, forcing the oil into the lubrication system. They are known for their simplicity, reliability, and ability to handle a range of viscosities.

Another type is the vane pump. Vane pumps consist of a rotor with movable vanes that slide in and out of slots. As the rotor turns within an eccentric housing, the vanes are forced outward, creating chambers that fill with lubricant on the inlet and empty on the outlet. Vane pumps are often favored for their relatively quiet operation and consistent flow.

Piston pumps are also used in lubrication. These pumps employ reciprocating pistons to draw lubricant into cylinders and then push it out under pressure. Piston pumps can generate high pressures and are often used in systems requiring precise metering of lubricant.

Finally, screw pumps are another option. Screw pumps utilize one or more rotating screws to move the lubricant axially from the inlet to the outlet. They are characterized by their smooth, pulsation-free flow and ability to handle viscous fluids. Each type has its advantages and is selected based on the specific demands of the application.
