一、190柴油机机油泵的改进 190柴油机机油泵泵轴由于采用单头支承,摆动大,因而泵轴、泵体轴孔(支承座)、内外转子磨损较快,磨损严重时容易造成无油压、烧瓦等故障。为此,在我县农机厂协助下,对原机油泵作如下改进:新加工一根泵轴,总长比原轴长8~(-0.30)毫米,长出部分直径为12~(-0.01)毫米,其余尺寸同原轴;在泵盖上加工一轴孔,轴孔中压入一自制青铜轴承(尺寸
First, the improvement of 190 diesel engine oil pump 190 Diesel engine oil pump shaft due to the use of single-head support, swing, so the pump shaft, the pump shaft hole (bearing), internal and external rotor wear faster, severe wear and tear likely to cause no oil pressure , Burning tiles and other failures. To this end, with the help of our county agricultural machinery factory, make the following improvements to the original oil pump: a new pump shaft, total length of 8 ~ (-0.30) mm longer than the original shaft, grow part of the diameter of 12 ~ (-0.01) Mm, the remaining dimensions of the same axis; machining a shaft hole in the pump cover, shaft hole pressed into a homemade bronze bearings (size
