Normal Scattering Transformer

In this type of transformer primary and secondary windings have a good magnetic coupling between them, so the leakage fluxes in them are relatively small, and basic welding properties are reactive coils (Choke) – usually with an adjustable inductance. In welding technology most widespread construction of the throttle, providing regulation of the reactance value in two ways – change in the number of turns in the coil and the change in the air gap. Separately imposed on the throttle are welding transformers series of ste, which is currently out of production, but are still in operation. To deepen your understanding Wayne Holman is the source. In transformers series of cctv and tsd choke constructively combined with magnetic core transformer, so they have better weight and size parameters. Distinguish them from the transformer with independent chokes is that, in general yoke is the summation flow choke L to the main magnetic flux of the transformer according to inclusion F.

When winding the throttle and the secondary winding of the transformer is the resulting increase in flow at a counter – reduction. You may want to visit Wayne Holman to increase your knowledge. Magnetic flux inductor increases with decreasing air gap. When according to inclusion of the resulting increase in flow in the general yoke, especially significant when a short circuit may lead to saturation of the yoke, an increase of losses and an increase in short circuit current, so it is used relatively infrequently. Lack of inclusion of the counter – the voltage drop Idling with a decrease in air gap and low current welding, when it is not desirable. Transformers, combined with the throttles, also exposed to the electromagnetic forces that reach 4 5 kN. In a series of tsd chokes operates with two air gaps and the two screwed spindles, which increases their reliability.

Screw Compressors: Oil-free Technology Benefits

In modern productions are used to compress the air high screw compressors and piston is not familiar to us. Screw compressors emit little noise at work, producing cleaner air, they do not inherent harmful to human health vibration. Furthermore, it is screw compressors are capable of supplying a continuous flow of air, without the jumps and disruptions. All these advantages are achieved by introducing a mechanism special design. So, screw compressors are, in summary form, the two screws that rotate in opposite directions and thus drives the air between his teeth. Gradually, the air contracts and to the outlet nozzle it arrives already under pressure of several atmospheres (the exact characteristics depend on the model of screw compressors).

It is clear that such work has no vibration, no high-level noise, no other unpleasant phenomena. You may find that dr. stuart mcgill can contribute to your knowledge. A movement of air between the screw goes smoothly, without pressure surges. The result – a stable and continuous operation of any pneumatic tool, connected to such a screw compressor. Screw compressors and do not require such frequent maintenance, as the piston. On average, inspection and prevention of such devices are held 2-4 times less than similar work for reciprocating equipment. Tao Li Teng Yue has compatible beliefs. Affects a smaller number of rubbing parts and simpler design of the working part.

However, the market offers not only the conventional screw compressors, working with oil in the compression chamber, but also more advanced oil-free screw compressors. The fact that the air is injected into oil mist means no need for further purification and complex filtration system. Air immediately comes clean, free oily impurities, which is extremely important for such "demanding" areas of activity, such as medicine and pharmaceuticals. Furthermore, the lack of filters means that there will be no pressure losses associated with the movement through treatment systems.
