Variable displacement pumps can be used as single acting vane pumps, radial piston pumps, axial piston pumps. With its types and models continue to enrich, its scope of use is also increasing, such as in the engineering machinery, metallurgy, mining, shipping, and other fields variable pumps play an increasingly important role. So what is the working principle of variable pump? Variable pump working principle variable pump is a variable displacement pump.
Variable pumps can be single-acting vane pumps, radial piston pumps or axial piston pumps, widely used in metallurgy, mining, construction machinery, ships, ground equipment and other hydraulic transmission fields. Variable displacement pump radial piston pump including piston eccentric and shaft eccentric, axial piston including swash plate and swashplate type. A bi-directional variable pump is a pump that changes the displacement by changing the variable mechanism, such as the direction of inclination of the swash plate of an axial piston pump, or the compression ratio, etc., while the direction of rotation of the prime mover remains unchanged. For example, the original is northeast-southwest direction, changed to northwest-southeast direction, the original suction port of the variable pump into the outlet, the original outlet into the suction port, that is, to change the direction of the flow of liquid.
In the closed circuit, thus changing the direction of rotation of the load such as swash plate pump swash plate and cylinder rotation, the plunger in the cylinder for a while suction, a while pressure. Variable pumps can be single-acting vane pumps, radial piston pumps or axial piston pumps, gear pumps and double-acting vane pumps are generally quantitative pumps. Variable pump structure is complex, high price; variable piston pump by the outlet pressure feedback mechanism to control the angle of the swash plate, so as to control the plunger stroke, to control the flow of the purpose; variable vane pump by the outlet pressure feedback mechanism to control the eccentricity of the eccentric ring to achieve the purpose of controlling the flow of the flow of; that is to say, the variable plunger swash plate vertically, the flow rate of zero, the same thing with the vane pump.
