Algorithm
General : Specification or process that follows a specific scheme and that solves a problem. This can be a mathematical formula, a flow diagram or a program. In control technology : Algorithm is used to
Scraper
Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in then form of a seated or ball valve. One of the most important sources of contamination in hydraulic
Proportional valves
throttle function as well. This is why its control pistons feature fine control grooves . If required, a can be located downstream so that a flow control function is achieved in addition to the directional function [...] 90° phase lag are the result. If this proves to be insufficient, high response proportional valves can be used.For pilot actuation purposes, proportional valves with larger nominal sizes use either two
Wheel motor
Hydraulic motor , which can be integrated directly into the wheels of a vehicle. This produces a direct transfer of the force without interposing a manual transition, cardan shaft and differential gear
Indirect actuation
pilot actuation ). In addition, the main device and the operating element (generally a pilot valve ) can be separated from each other, making remote controls an option.
SAE flange
PSI (210/420 bar), nominal widths of 15 to 50 and fastening screws with UNC threads. The SAE flange can be used as a two-part flange to connect pipelines to non-split counterfaces or as a one-part flange
Initial pressure difference ΔpA of filters
addition information on the dirt holding capacity of a filter is necessary, as a filter with a low ΔpA can clog quicker than a filter with a higher ΔpA (see filter life ).
Response sensitivity
(Figure A 21). The parameter is stated in mA or in % of the nominal current (DIN 24 311). The term can best be explained using digital technology: A five-stage digital valve has 25—1 = 31 steps between
Heat balance in hydraulic systems
container is primarily involved in this. Depending on the ventilation of the surface A, k = 5.8–11.6 W/m2K can be used if the temperature difference is at least 25°C. This creates a heat balance. If the stationary
Hamming distance d
string with a Hamming distance of d = 2 offers greater transmission security, since single errors can be detected and corrected. Only double errors will cause something to look like another code word.
