国产深松犁铧与进口深松犁铧对比试验

设计研制了国产深松犁铧,在同等试验条件下,与进口犁铧进行了耐磨性和作业质量对比试验。结果证明,两种犁铧的磨损量相差不大,但国产犁铧的均方差较大,说明国产犁铧生产技术不稳定,耐磨性能波动较大。在作业质量方面,国产深松犁铧与进口深松犁铧处于同等水平,作业性能稳定,符合相关标准要求。 

Comparative Test of Domestic Deep Pine Plowshare and Imported Deep Pine Plowshare

Domestic deep pine plowshare was designed and produced.Under the same test conditions,comparative test about wear resistance and working quality between domestic deep pine plowshare and imported deep pine plowshare was carried out.Results showed that there was little difference between two kinds of plowshare.But mean square deviation of domestic plowshare was larger.It showed that domestic share production technology was not stable and wave of wear resistance was larger.In terms of quality of work,domestic deep pine plowshare and imported deep pine plowshare were at same level.Job performance of domestic deep pine plowshare was stable and it met requirements of relevant standards.
