1.不能用汽缸盖压装汽缸套。有的农机手在安装汽缸时,不装汽缸垫,直接装上汽缸盖,通过拧紧汽缸盖螺栓压装汽缸盖。这样,当汽缸套压到位后,汽缸盖的压力全部作用在仅3mm左右的缸套台肩上,会导致汽缸套断裂。正确的安装方法是:将木板放在汽缸套上端,用锤子轻敲木板,直至汽缸套装到位。2.不能用压缩空气冲洗汽油箱。焊修汽油箱前,必须先将油箱内的汽油洗净。有的修理人员用压缩空气冲洗油箱,由于油箱口较小,汽油分子在箱内因发生强烈碰撞会产生火花,易引起爆炸,造成人身伤亡事故。应使用清洗剂清洗汽油箱。
1. Cylinder head can not be used to press cylinder liner. Some agricultural machine hand when installing the cylinder, the cylinder liner is not installed directly mounted on the cylinder head, cylinder head bolts by tightening the pressure cylinder head. In this way, when the cylinder sleeve pressure in place, the pressure on the cylinder head all the role of only about 3mm cylinder liner shoulder, will lead to cylinder liner fracture. The correct installation method is: put the board on the cylinder liner, tap the board with a hammer until the cylinder set in place. 2. Do not flush the fuel tank with compressed air. Before repairing the fuel tank, you must first wash the fuel tank. Some repairers flush the fuel tank with compressed air. Due to the smaller fuel tank mouth, the gasoline molecules will generate sparks in the tank due to strong collision, which may cause explosion and cause personal injury or death.
