لماذا لا يتم استخدام الشواحن الفائقة لآلات البناء على نطاق واسع؟
The reason why construction machinery superchargers are not widely used?
Construction machinery supercharger is not widely used for a very important point or cost, manufacturing is not only limited by the design of the blades and the overall strength, and in addition to the gears, it other components are cast in one piece. The shape of the compressor rotor angle and a series of other parameters have a large impact on the boost value of the supercharger, that is, to reduce the resistance of the mechanical boost to the engine running at high speed, which requires high design technology and is not ideal for economic models.
In order to balance the boost value and engine load, choose to assemble mechanical supercharging engine is generally relatively low speed, in high speed supercharger internal blades will have a large resistance, this resistance is caused by the loss of speed output force, after a certain speed threshold, this resistance will make the engine withstand a great load, too high under the loss of boost value is not worth the loss, reduce the mechanical supercharger operating resistance is the key to reducing the loss of power of the supercharger at high speeds.
Compared with mechanical supercharging, turbocharging not only does not consume the power of the engine itself, but also brings good power output and improves fuel economy in medium and high operating conditions, and turbocharging is more suitable for the mainstream small displacement engines nowadays. In contrast, turbocharging has more advantages, but its Z major shortcoming is its late turbo intervention time, resulting in a small boost range and low torque in the early stage, in order to solve this problem, engineers have been working to improve the phenomenon of turbo lag, so that turbocharging can be closer to linear (naturally aspirated).
يمكن إظهار مكاسب الطاقة الأعلى التي يمكن تحقيقها باستخدام الشحن التوربيني بشكل مرئي أكثر في الأشكال. إنه أيضًا بسبب الاحتفاظ المرتفع بالشاحن التوربيني وانخفاض تكلفة التطبيق من جميع النواحي ، أصبح الآن خيارًا سهلاً للوافدين الجدد إلى معسكر الشاحن الفائق.
