HAWE eControl - Condition monitoring functionality significantly expanded
All common proportional controls, such as are used with directional valves, pressure valves, or pump controllers can be managed with this amplifier. It is designed as a DIN plug, and is simply mounted
Pump with banked pistons/in-line piston pump
Fluidlexikon Pump with banked pistons/in-line piston pump Hydraulic pump with pistons arranged alongside one another and perpendicular to the drive shaft Piston ( Figure R 24 ). They are preferably made [...] operation . Pumps with banked pistons/in-line piston pump with multiple pistons are now worthless. Figure R 24: Pump with banked pistons/in-line piston pump
Pump elements
Pump elements Pump elements convey lubricating pressure fluids and at the same time generate a back pressure against the working resistance of a connected actuator. DMPE Tipo de aparato: Elemento de bomba
Adjustable displacement pump
(Figure E 11) . After adjustment such a pump operates like a constant pump . Figure E 11: Adjustable displacement pump, variable displacement axial piston pump type V60N [...] Fluidlexikon Adjustable displacement pump Variable pump on which the geometric displacement can be set (limited) to a specific flow rate . This setting is made, e.g., by means of a stop screw that fixes

Pressure controller for a variable pump
Fluidlexikon Pressure controller for a variable pump Device that sets the delivery flow of a variable pump to zero on reaching a set pressure such that this pressure is maintained in the system (Figure [...] this device. As during this process the pump operates against the related system pressure, the resulting losses must not be underestimated. Here the losses in the pump often make up the major part of the losses [...] pre-selected on a case-by-case basis (see Pressure-flow (p-Q) control of a pump ).

Axial piston pump according to the swash plate principle Axial piston pump according to the swash plate principle (source: HAWE Hydraulik SE) Axial piston pump according to the bent axis [...] axis principle Axial piston pump according to the bent axis principle (source: HAWE Hydraulik SE) When designing an axial piston pump, it is not only the functional principle that comes into play, but also [...] Fluidlexikon Axial piston pump Axial piston pumps have several pistons that are arranged parallel to the drive shaft. They are available as either variable pumps or constant pumps. Axial piston variable
Annular gear pump/motor
Fluidlexikon Annular gear pump/motor Special form of internal gear pump , in which no sealing sickle is required, as the seal between the fixed gear ring and the rotor (planetary gear) is directly possible [...] best-known design of the annular gear motor is the orbit motor .
