Swash plate pump
Construction design of an axial piston pump , in which the swash plate and the control disc are firmly connected to the drive shaft and rotate with it, while the cylinder block, which is firmly connec
Swash plate machine
Axial piston machine ( Axial piston pump or Hydraulic motor ) with a rotating cylinder block in which the piston strokes are caused by a fixed swash plate with a largely adjustable drive angle (max. a
Paraffin base oil
The base oil is of the paraffin variety. Paraffin base oils have a low aromatic content; they are associated with good lubricating performance and favour high loads during continuous operation. They o
Constant pressure system
System in which the pressure at the hydraulic pump remains constant regardless of the flow rate and how high the load pressure is. Strictly speaking, this is only really the case with: controls with t
Programmable control
memory programmable control with random access memory (RAM) as program memory ( semiconductor memory ) the entire contents of which can be changed, even only slightly, without mechanical intervention
Two edge control
1. Hydraulic resistance control for a displacement chamber with a type A hydraulic half bridge (adjustable input and output resistance); use of both control edges of a continuously adjustable 3/2-way
Step diagram control
Form of process-dependent workflow control, in which the switching conditions depend only on position-dependent signals of the controlled system (according to DIN 19 237).
Switching methods for hydraulic pumps
Considerations on switching methods for hydraulic pumps are necessary if several pumps are used in a hydraulic system . A distinction is then made between ( Figure S 17 ): two-circuit or multi-circuit
Pressure regulator (zero-stroke regulator)
Fixture which changes the flow rate of a variable pump in such a way that is becomes ever smaller as the pressure increases (e.g. up to around 5% of Q max). The pressure at which adjustment starts is
