进口的福克森、菲亚特等拖拉机、达克汽车及一些工程柴油机上使用DPA型分配式喷油泵。该分配泵与国产分配泵零件尺寸不同,个别零件大小相差悬殊,不能互换,给修理带来困难。多年来,我们采用了下述几种办法修理了不少DPA型分配泵,经与发动机配套使用,基本上符合发动机性能要求。 1.传动箱联接花键轴的改制花键轴一端铣成国产齿形,另一端为进口齿形,经过这样改制后的花键轴,使进口泵可用在国产的拖拉机上,同样使国产的分配泵也可用到进口的拖拉机上。
Imported DPR type distribution pump on tractors like Fordon and Fiat, on vehicles from Ducks and some engineering diesel engines. The distribution pump and domestic distribution pump parts of different sizes, individual parts vary in size, can not be interchangeable, to repair difficulties. Over the years, we adopted the following methods to repair a lot of DPA-type distribution pump, with the engine supporting the use of basically meet the engine performance requirements. 1. Gearbox coupling spline shaft milling one end transformed into domestic-made spline tooth profile, the other end of the import toothed, splined shaft after such restructuring, the import pump can be used in domestic tractors, the same make domestic Dispensing pumps are also available on imported tractors.
