农用柴油供应,目前不少地方还是基层供销社。由于没有过滤装置,油中的杂质很多,严重地影响着机器燃油系统精密偶件的使用寿命,有的只能使用两三个月。镇平县石佛寺乡苏寨村机手杨思德和城郊八里庙村机手刘玉超,在手扶拖拉机原有一个柴油滤清器的基础上,又在输油管上另加一个柴油滤清器,采用双滤器。使用表明,效果很好。县农机管理站的技术人员根据这两位机手的经验,自制滤清器,其结构见图(图中箭头指向为燃油流动方向)。通过在手扶拖拉机上的对比试验证明,采用双滤器,精密偶件的 Agricultural diesel supply, at present many places or primary supply and marketing cooperatives. Because there is no filter device, a lot of impurities in the oil, a serious impact on the life of precision fuel system components, and some can only use two or three months. Zhenping County town of Shizuisu Suzai Village, handguns Yang Side and suburban Bali Temple Village hand Liu Yuchao, walking tractor in the original a diesel filter, based on the pipeline plus another diesel filter, using double filter. Use shows that the effect is very good. County agricultural management station technicians based on the experience of these two drivers, homemade filter, the structure shown in Figure (the arrow pointing to the direction of fuel flow). Through the comparison test on the walking tractor proved that the use of double filters, precision couplings
