在许多进口工程机械上柴油机调速器有所谓“安革莱希”(Angleich)弹簧。我们知道,为了充分利用柴油机的充气量,提高柴油机的后备功率,改善柴油机的扭矩特性,以及在增压柴油机中,使供油特性与增压充气特性相适应,有个“扭矩校正”问题,因而燃油喷射系统就有个“校正供油”问题。“校正供油”是靠调速器中的校正装置实现的。与一般调速器的机理相同,校正过程实际上是个局部调速过程,也是通过飞锤所感应的离心力与校正弹簧力的平衡过程来控制高压油泵供油齿杆的位移,从而实现增加或减少油量的校正供油。“安格莱稀”弹簧就是调速器“校正弹簧”。由于高压泵柱塞偶件的相对密封性与柱塞
On many imported construction machinery diesel engine governors have so-called “Angleich” springs. We know that in order to make full use of the diesel engine’s aeration, increase the backup power of the diesel engine, improve the torque characteristics of the diesel engine, and adapt the fuel supply characteristics to the supercharging and aeration in a turbocharged diesel engine, there is a problem of “torque correction”. As a result, the fuel injection system has a “correction oil supply” problem. The “corrected oil supply” is achieved by means of a correction device in the governor. Similar to the general governor mechanism, the calibration process is actually a partial governor process. The displacement of the high pressure oil pump oil rod is also controlled through the equilibrium process of the centrifugal force induced by the flyweights and the correction of the spring force, so as to increase or decrease the displacement. Correction of oil supply. The “Angler” spring is the governor “correction spring”. Due to the relative tightness and plunger of the high pressure pump plunger assembly
