驾驶拖拉机不遵守操作规程,不仅会造成零部件严重磨损,影响机车的使用寿命,且易发生人身事故,造成不应有的损失。下面谈几种常见的错误做法。1.有的驾驶员习惯于在发动机刚起动着火和熄火前轰几下油门;有的用轰油门作信号,拿油门当喇叭。这些做法都十分有害,因为突然增大和减小油门,发动机转速会猛增和猛减,因而产生很大的冲击力,易使柱塞弹簧、气门弹簧折断。同时还会造成发动机的曲轴、连杆瓦、活塞和缸套等零部件加速磨损,甚至损坏。猛轰油门使燃料燃烧不完全,拖拉机冒黑烟,使气缸内积炭增多。未燃烧的柴油顺缸壁下流,冲淡缸壁油膜,流入油底壳会稀释机油,降低润滑效果。
Driving tractors do not follow the rules, not only will cause serious wear and tear parts, affecting the service life of locomotives, and prone to personal accident, resulting in undue loss. Here are some common mistakes. 1. Some drivers are accustomed to the engine just starting the fire and flame a few times before the throttle boom; some with the boom throttle signal, take the throttle when the horn. These practices are very harmful, because suddenly increase and decrease the throttle, the engine speed will soar and fierce, resulting in a great impact, easy to make the plunger spring, valve spring break. At the same time can also cause the engine crankshaft, connecting rod, piston and cylinder parts and other parts accelerated wear and tear, or even damaged. Throttle throttle fuel combustion is not complete, tractor black smoke, the cylinder increased coke. Unburned diesel fuel along the cylinder wall, dilute the cylinder wall film, into the oil pan will dilute the oil, reducing the lubricating effect.
