根据机械磨损理论,随着机械使用年限的增加,零部件正常磨损加剧,设备的使用效率会随之下降,当磨损达到一定程度时,就会出现明显故障,此时就需要对设备进行部件更换等维修,复原设备基本性能。国内工程机械维修行业形成已久,早在20世纪50年代国内工程机械行业诞生之前,我国就已经拥有一批工程机具修配点,正是在他们的基础上,工程机械产业才逐渐开始萌芽。
According to the mechanical wear theory, with the increase of the service life of the machine, the normal wear and tear of the parts and components will be exacerbated, the efficiency of the equipment will decrease. When the wear and tear reaches a certain level, obvious faults will occur. At this time, the equipment replacement And other maintenance, recovery equipment basic performance. China’s construction machinery repair industry has long formed. As early as the 1950s, China’s domestic construction machinery industry was born. China already owned a batch of construction machinery repair and distribution points. It is on this basis that the construction machinery industry began to sprout.
