微耕机常见八大错误保养方法
时间:2013-03-06 来源:本站 作者:管理员

 1、乱紧机体上的螺丝。 微耕机多配备的是铝合金箱体的发动机,铝合金的硬度显然不及球墨铸铁,因此所有上在机体上的螺丝必须按照规定扭距用力,特别是缸盖螺丝,稍不注意就会“拉丝”。而且尽量不要在热机时紧螺丝。 

 
2、燃油箱盖漏油用薄膜纸封死。封死油箱以后,长时间工作就在油箱内产生负压,导致进油不足,使机器在工作时冒黑烟,动力不足。
 
3、不重视燃油和润滑油的质量。燃油质量差,不仅使机器动力不够,而且加速了油泵和芯套的磨损;润滑油的好坏,直接影响机器的启动性能和使用寿命,千万马虎不得。宜昌市窑湾乡沙河村的卢其兵反映,他的机器一直用的很好,就因为有一次作业时缺了润滑油,加了一次再生机油,结果机器性能全面下降,最后经过大修才解决问题。
 
4、风冷机用水降温。有些机手看到风冷机温度较高,担心损坏机器,用浇水的方法帮忙降温。其实是非常错误的做法,用水骤然降温,缸套突然收缩,容易拉缸,断环,甚至缸套破裂。 
 
5、乱拆风冷机的导风罩和挡风板。有的机手不知导风罩和挡风板的作用,以为是挡泥土的东西,可要可不要,任意拆卸,致使风扇的风无法集中,失去了降温的效果。 
 
6、柴油雾化不良只换油嘴 。柴油雾化不良除油嘴问题外,多是高压油泵磨损,压力小,油量少造成。 
 
7、不重视班保养。有的机手认为几天搞一次保养就行了,其实,磨损是日积月累的过程,班保养一样主要。 
 
8、发动机偏盖垫不当使用密封胶。偏盖垫使用密封胶后,多余的胶容易进入齿轮箱,由于长时间的工作和机油泵的吸力,密封胶很容易堵塞机油进油孔,使曲轴和连杆得不到有效的润滑。
