怎样预防连杆折断SL一50/55原油拖拉机的连杆很易折断,折断部位都在连杆小端。北安拖拉机站在1954年作业中就断了7根连杆,其他国营农场也发生过这样的事故。连杆小端很单薄,特别是在固定螺丝附近。所以我们在使用这种拖拉时,一定要防止过负荷,使发动机运转得很圆滑,排气管不冒黑烟。经验证明,连杆折断多设生在高速翻地或开荒作业中。在使用燃油方面也要注意。在这种拖拉机上使用苏联一号轻柴油时有敲击现象。如果因为冬季燃油不易流动,可使用抚顺一号柴油或加强保温设备(如制造油箱保温被等)。根据使用经验,SL—50/55拖拉机每隔150小时就要清除活塞积炭,这时候就要仔细检查活塞及连杆各部(特别是连杆小端固定螺丝)。
How to prevent connecting rod break SL 50/55 crude oil tractor connecting rod is very easy to break, broken parts are in the small end of the connecting rod. North An tractor station in 1954 operations in the off seven links, other state-run farms have also had such an accident. The small end of the connecting rod is very thin, especially near the fixing screw. Therefore, when we use this drag, we must prevent overload, make the engine run very smoothly, the exhaust pipe is not black smoke. Experience shows that the connecting rod break more set in high-speed land or wasteland operations. Also pay attention to the use of fuel. In this tractor using the Soviet Union on the 1st light diesel oil percussion phenomenon. If the flow of winter fuel is not easy, you can use Fushun diesel or to strengthen the insulation equipment (such as the manufacture of fuel tank insulation, etc.). According to experience, SL-50/55 tractors every 150 hours to clear the piston coke, then carefully check the piston and connecting rod ministries (especially connecting rod small end fixing screws).
