The pneumatic drive systems homogeneous energy control subsystem works with pneumatic signals. Pneumatic signals have a low energy level, most often the signal pressure exceeding 2 bar. Conventional values ninja kitchen system 1200 "0" and "1" assigned to pneumatic signals corresponding to predetermined pressure range. In most cases, these fields are: 0 ... 0.2 bar for a logical "0" 0.8 ... 1.4 bar for a logical "/". Figure 4.147 are highlighted these areas; also observed between the two areas of safety zones. Pneumatic logic elements serve to materialize the basic logic functions. They have a discreet operation, a modular design and small size gauge.
Usually, a logic element are characteristic one or two inputs (i1 and i2) and output (s). 's Output may be "0" or "1" according to the signals existing at one time at the inlet and logical equation which materialize the item. The output signal can come from a source of constant pressure, in which the element is active, or directly from an input signal, in which the element is passive. There are a wide variety of logic elements, which are distinguished by: logical equation that materializes; way that distributes; the working pressure; nominal size etc. Manufacturing firms realize economic reasons pneumatic logic systems comprising a small number (2-4) of logical elements, given that all basic logic functions can be realized through: the three basic functions: negative (NO), disjunction (OR) and conjunction '(AND); ninja kitchen system 1200 two universal logic functions: OR (NOR) and ONLY (AND-NOT), representing contraction of two basic functions; AUX memory. The main criterion for the classification of the logic is the way they made the distribution; from this point of view there are two main families: elements without moving parts, called "fluidic"; items with moving parts. These fluidic logic elements based their operation on different principles [4.3] of that remember: - attaching jet of fluid to the wall (Coanda effect); - Transformation of a laminar jet in turbulent jet; - Induction jets; - Focus jets. The principle used is that of the wall effect, principle Romanian ninja kitchen system 1200 scientist named H. Coanda, who one described and explained for the first time.
To explain this principle is considered an air jet (fig.4.148), obtained by the air flow under pressure through a nozzle and its relaxation environment. ninja kitchen system 1200 Because the viscosity of the jet interacts with the ambient air, at rest, training the latter one moving.
The flow rate of the jet, initially considered turbulent, the output section Si is constant. In another section, located at distance x from the output section, the jet retains its original speed in a central area, an area which as x increases is reduced increasingly more. Observe while a broadening of the jet, as x increases, and at some point a gradual reduction in its flow rate. If the jet is near a wall (fig.4.149) jet will direct you to p
