Rexroth REXROTH oil pump features: Depending on the tilt piston pump Rexroth components, there are two kinds of swashplate Cline. A swash plate rotatable relative to the swash plate has an inclined angle of the cylinder, causing the plunger is reciprocated in the pump cylinder. The drive shaft axis and the axis of the cylinder is the same. This structure is relatively simple, high speed, but high working conditions, the contact end portion of the plunger and the swash plate is often the weak link. Inclined axis of the drive shaft axis and the axis of the swash plate is the same. It is due to the plunger cylinder inclined at an angle relative to the drive shaft reciprocates the plunger. Flow regulation relies on the swing angle of the cylinder plunger to achieve, so some also called swing-cylinder. Compared with the swash plate, reliable, flow, but the structure is complicated. Comparison of axial piston pumps and radial piston pump discharge pressure is high, it generally work within 20 ~ 50MPa range, high efficiency, small radial size, compact structure, small size and light weight. But the structure is more complex radial piston pump, manufacturing requirements, more expensive. Axial piston pumps are generally used for machine tools, metallurgy, forging, mining and lifting machinery, hydraulic transmission system, particularly widely used in high-power hydraulic system. To improve efficiency, the axial piston pump should generally by block, oil pan, the plunger and the swash plate and other major parts. A plurality of the cylinder plunger, is axially aligned, i.e., parallel to the center line of the plunger shaft axis, so called axial piston pump. But it is different from the reciprocating piston pump, not only because of its reciprocating motion of the plunger in the pump cylinder and the pump cylinder and piston and a rotating motion relative to the swash plate. Contacting the spherical end of the plunger head and a swash plate. In the high-low pressure valve plate with crescents grooves are spaced from the wall, to ensure a certain tightness, which are in communication with the pump inlet and outlet ports. A swash plate tilt angle between the axis of the cylinder axis. Rexroth pump swash plate design has slotted controlled, continuously variable displacement, good self-absorption, allowing continuous working pressure of 350bar, low noise, long life, the drive shaft can absorb axial and radial loads, modular design, through the short axis of the drive control, the pump optional position, the mounting position can be selected to operate with the HFC fluid at a reduced operating parameters.
