起动加浓与加速冒烟常常是一对矛盾,如何解决是调速匹配中的一个课题。目前解决办法多采用齿杆限位器,并适当设定它的位置。其实,一般起动油量为1.2倍的额定油量时,应采用齿杆硬点限位。当起动油量大于1.5倍的额定油量时,则应采用弹性限位。 国产A型泵常常有烟度弹性限位装置,即烟度限制器。在修理调试中,一些维修人员往往将烟度限制作为齿杆硬点限位器来设定起动油量,而使烟度限制作用没有充分发挥, Start enrichment and accelerating smoking is often a contradiction, how to solve speed matching is a subject. The current solution to the use of more rack bar stopper, and set its proper position. In fact, the general starting fuel capacity of 1.2 times the rated fuel, the gear rod should be used hard limit. When the starting oil is greater than 1.5 times the rated fuel, you should use the elastic limit. Domestic A-type pumps often smoke elastic limit device, that smoke limiter. In the repair and debugging, some maintenance personnel often limit the smoke as the gear rod hard limit stopper to set the starting oil, leaving the smoke limit is not fully exerted,
