Kv factor (speed/stroke gain)
the stiffness and accuracy of a drive. Kv is limited by the stability of the control circuit, which can be simplified and calculated as follows ( Figure K 43 ): At a given level of damping D, the maximum
Centralised hydraulic oil supply
reduced if the individual consumers require hydraulic oil at different times. Equally, multiple circuits can be simultaneously supplied with hydraulic oil without reactions, as the central hydraulic oil supply
Oscilloscope
screen, set things down on paper and save curves. In addition, since the cathode ray oscilloscope can process signals of up to around 100 MHz, it has now largely eclipsed the other principles.
Throttle valve
throttle valve does not have a return connection, the portion of the flow rate removed by the throttle can only be removed from the circuit via the system's pressure-limiting valve. As this valve is set to
Thermoplastics
parts lose their form (voltage). When cooling, plastification of the materials may occur This process can be repeated as desired. Seals or sealing parts made of thermoplastics must therefore not be heated
Switching capacity of directional valves
Dynamic switching capacity : States the pressure p and flow rate Q at which a directional valve can still be switched ( Figure S 16 ). This is particularly important in the case of directly controlled
Swivel motor
toothed rack pistons, which enter into a transversally mounted sprocket ( a ). This construction type can be built for up to 2 x 360° pivoting angles and offers the largest torque; pressure range up to 200
Constant pressure system
pressure changes (Figure K 29) , although they offer the advantage that loads connected in parallel can also be operated with one pump at the same time (e.g. parallel circuit ). In the field of electro-hydraulic
Pump control
system may be more cost-effective, consisting of one variable pump and several constant pumps , which can then be connected as desired ( Figure P 37 ). As larger masses are to be moved in the pump with the
Temperature measurements in hydraulics
The temperature of the hydraulic fluid in hydraulic systems can be measured either with simple measurement devices (thermometer) or with a measuring device that issues signals to the control unit. The
