Magnetic filter
Filter with a permanent magnetic element for retaining ferromagnetic particles. Magnetic filters are often combined with fleece or screen filters and thereby increase the amount of contamination they retain
Servo-suction valve
half open hydraulic circuit. Normally with cylinder drives with a pulling load, throttling is performed at the side with the piston load until a balance is reached with the load.
Orbit motor
motor whereby the outer ring with its seven teeth remains still, while the inner wheel with its six teeth performs a planetary-type movement. As a result, a volume associated with 6 → 7 = 42 gaps between teeth
Replacement orifice diameter
orifice diameter is calculated with For parallel configuration the replacement orifice diameter is calculated with Calculate the replacement orifice diameter directly and easily in our hydraulic calculator [...] For two orifices with diameters d1 and d2 which are connected in parallel or in sequential, the diameter dE of a replacement orifice can be calculated. For sequential configuration the replacement orifice
Servo cylinder
Figure S 53 ) are used with two construction designs, which differ in terms of the bearing of the piston and piston rod: 1st cylinder with hydrostatic bearing and 2nd cylinder with contact seals, which must [...] These special seals are normally made of Teflon. Servo cylinders, together with the load, form a system capable of oscillation with a relatively low natural frequency (between 10 and 100 Hz) and very low
Accumulator drive
accumulators are to be designed in accordance with DIN 24 552 with a pressure measuring device, safety device to protect against overpressure ( safety valve ) and with a shut-off device. These devices are normally [...] ucing valves have to be used (storage losses). Accumulator drives are equipped with constant pumps or variable pumps with a pressure controller . They become more cost-effective as more consumers are supplied [...] Variation of central hydraulic oil supply (system with impressed pressure), in which a hydraulic accumulator performs the task of providing energy at power peaks. This can be used to select the flow rate
Multi-circuit pump
separate circuits with a pressure-limiting valve because their working cycles overlap. If a constant pump is involved, the installed power will be equal to the total for the corner power . With variable pumps [...] pumps , it is possible to make better use of power from pumps operated simultaneously with the help of a sum power controller or limit load control .
Plug-in valve
Valve on which the housing is in the form of a cartridge and with port openings that are aligned with the ports in the installation space (e.g. 2-way plug-in valve).
Throttle forms
differentiation is made between constant throttles with the two forms of nozzle and orifice that each have a pre-defined bore. There are also adjustable throttles with a changing cross-section that can have different [...] The most common form of variable throttles are needle throttles, the longitudinal notch with orifice and with triangle, the peripheral notch and the slotted throttle.
Circuit diagram
and –– together with the function diagram — forms the basis of the search for an error. The schematic is designed in accordance with DIN 24 347 and using switching symbols in accordance with DIN ISO 1219 [...] Illustration of a system with symbols (previously: switching symbols) to illustrate the order of the individual devices and their functional workflow. The circuit diagram must therefore allow the iden
