友好型机车加煤机的原动机从苏联进口图面集上所标之类型是C及C_1两种,二者构造相同,仅有个别尺寸不同.具体阀装置上之主要区别是:C型原动机进汽余面为0.5毫米,排汽余面为0.2毫米;C_1型原动机进汽余面为1.0毫米,排汽余面为0.但二者之余面与导程之和均相等.其原因是二者之偏心杆及偏心距尺寸相同.本文要探讨的是先进角12°50’的由来,及主曲拐由前死点转到后死点汽室阀位移的2(余面+导??)是多少?我们通过计算发现所得之数较原设计数字(图面集上的)小1.0毫米.因而提出了在原动机
The prime mover of the friendly locomotive stoker machine is of the type C and C_1, both of which are constructed in the same way and only differ in individual sizes.The main differences on the specific valve device are as follows: Type C Motive intake steam surface is 0.5 mm, exhaust steam surface is 0.2 mm; C_1 prime mover intake steam surface is 1.0 mm, exhaust steam surface is 0. But the balance of both the surface and the lead are equal. The reason is that both the eccentric rod and the eccentricity are the same in size.This paper discusses the origin of advanced angle 12 ° 50 ’and the transition of the main crank from the front dead center to the rear dead center steam valve displacement of 2 + Guide) What is the number? We found that by the calculation of the number of the original design numbers (on the set of drawings) is 1.0 mm, and thus proposed in the prime mover
