柴油机在标定工况下运转时,如遇到外载荷增加,则发动机的转速就会下降,调速器的转速也相应降低,所产生的离心力也跟着减小;这时油门拉簧压向限油器的力相应增大,由于柴油机的限油器(例如X 195柴油机用装在齿轮室盖上的螺钉限制油泵齿条供油量位置)是刚性零件,所以在外力增大时,限油器不会被压缩,当然就不能加大油泵供油量。根据上述理由进行新的设计,将原来刚性限油螺钉改为可压缩装置,在外力作用下,能被压缩而增加油泵的供油量;此外,为了同时解决起动加浓这一要求,研制成如图1所示的新型油量校正器。两根弹簧装在件2内,两弹簧间装有支承滑套6。该滑套除了作顶杆1的
Diesel engine running in the calibration conditions, in case of external load increases, the engine speed will drop, the governor speed is also reduced, the resulting centrifugal force also decreases; then the throttle spring compression limit The force of the oil pressure increases accordingly. Since the oil pressure limiter of the diesel engine (for example, the screw on the gearbox cover of the X 195 diesel engine limits the oil supply position of the oil pump rack) is a rigid part, when the external force increases, Will not be compressed, of course, can not increase the fuel pump. According to the above reasons for the new design, the original rigid limit oil screw into a compressible device, under the action of external force, can be compressed to increase the fuel pump oil supply; In addition, in order to solve the start of the enrichment of this request, developed Figure 1 shows the new fuel quantity corrector. Two springs are mounted in the member 2, and two sliding springs 6 are mounted between the two springs. The sleeve except for the mandrel 1
