随着季节和工作任务的变化,大部分农用车辆往往处于长时间停驶状态。长时间停放的车辆,尤其是露天停放的车辆,受风吹、日晒、雨淋等自然侵蚀,使车辆极易出现金属生锈、橡胶制品老化、棉织物制品霉变、油料变质等情况,严重影响了车辆的技术性能和使用寿命。因此,在车辆长时间停放的过程中,要加强管理,针对不同情况,及时有效地采取防护措施,才能尽可能地避免或减缓车辆停放过程中各种外界因素对机件带来的不良影响,保持车辆的固有性能,使之处于良好的技术状态。1.金属机件锈蚀与防护金属锈蚀是指其表面出现黄褐色锈斑,失去光泽,严重时形成片或粉末状的氧化物剥落现象。结果使金属零件断面尺寸逐渐缩小,机 As the season and work tasks change, most of the agricultural vehicles are often in a long time stopped. Vehicles parked for a long period of time, especially vehicles parked in the open air, are naturally eroded by wind, sun and rain, making the vehicles prone to metal rusting, aging of rubber products, mildew of cotton fabric products, deterioration of oil materials, etc., Seriously affected the vehicle’s technical performance and service life. Therefore, in the process of long-term parking of vehicles, it is necessary to strengthen management and take timely and effective protection measures in different situations so as to avoid or slow down the adverse effects of various external factors on the mechanical parts during the vehicle parking as much as possible, Maintain the inherent performance of the vehicle so that it is in good technical condition. 1. Metal parts corrosion and protection Metal corrosion refers to the surface of the yellow-brown rust, tarnish, severe formation of flakes or powder-like oxide spalling phenomenon. As a result, the cross-sectional area of ​​metal parts is gradually reduced
