piston pump การใช้

• Piston pumps draw a piston through a cylinder to create suction.
• They are used to smooth out the delivery from piston pumps.
• For closed loop systems, normally axial piston pumps are used.
• That implies the following main applications for a radial piston pump:
• A multi-bladed windmill is a mechanical device with a piston pump.
• It was fitted hydrostatic transmission having the normal Rexroth Hydramatic axial piston pumps.
• For example K鋜cher has several models powered by axial piston pumps with three pistons.
• Piston pumps are used in lower pressure applications.
• Piston pumps can be made variable-displacement by inserting springs inline with the pistons.
• A single-piston pump delivers liquid to the outlet only during the discharge stroke.
• Usually, piston pumps are used, because they can produce hundreds of atmospheres of pressure.
• The propulsion motor is of the axial piston pump type, and is capable of variable speed.
• Bearings are mounted on the piston pump shaft, which transfers drive torque to the cylinder block.
• A rich fuel / air mixture is injected by a small piston pump after the start of compression.
• Some direct drive piston pumps are driven by a gasoline engine with pressure control via an electric clutch.
• The pressure of the liquid is provided by high-pressure piston pumps motorized by the tank engine.
• Modernized axial-piston pump of type NAPOR equipped with automatic displacement control and hydraulic load sensing control.
• Generally, the 3 pumps used in excavators consist of 2 Variable displacement piston pumps and a Gear pump.
• Most electric powered airless pumps have an electric motor connected through a gear train to the paint piston pump.
• This was more complex to build than the long-established piston pumps, but had advantages in operation.
