用在DAC(俗称“达克”)6135卡车发动机上的DPAM分配泵属英国CAV公司DPA分配泵系列,该泵具有体积小、重量轻(6.5公斤)、结构简单、配套性能优良等优点。但对使用操作技术、燃油清洁度要求较高,因此,在实际使用中,故障情况明显比柱塞泵增多,其使用寿命有时也不令人满意。现将我厂1981～1982年所修该型号分配泵的故障情况如表1。 The DPAM distribution pump used on the DAC (commonly known as “Dak”) 6135 truck engine belongs to the DPA distribution pump series of British CAV Company. The pump has the advantages of small size, light weight (6.5 kg), simple structure and excellent matching performance. However, the use of operating technology, high fuel cleanliness requirements, therefore, in actual use, the failure conditions significantly increased than the piston pump, the service life is sometimes unsatisfactory. Now I plant from 1981 to 1982 repair of the model pump distribution failure in Table 1.
