Grasp the correct key points of agricultural machinery throttle to reduce potential safety hazards

Abstract: in busy farming season, agricultural machinery has become a good hand in the field, but there are also potential safety hazards. Grasp the correct key points of agricultural machinery throttle to reduce potential safety hazards

I. It is forbidden to step on the accelerator repeatedly before starting. Some drivers step on the accelerator repeatedly to make the carburetor and acceleration device work, so as to inject more gasoline into the cylinder to meet the needs of starting. This will not help the tractor to start, but will also increase the wear of the fuel injection pump control device and the fuel volume adjustment mechanism

II. When starting the engine, the throttle opening should be medium or small. When starting, refueling should be done. In the same standard, different sample sizes are often given for different materials. It is better to slightly step on the accelerator pedal before the clutch linkage point, and it is better to slightly step on the accelerator pedal higher than the idle accelerator. Releasing the clutch should be closely coordinated with stepping on the accelerator, and the action should be agile

III. reduce the throttle when releasing the clutch. Some operators do not reduce the throttle in time when releasing the clutch, which makes it difficult to determine the applicability of the engine's large throttle air-to-air fixture, resulting in a sudden increase in speed, which will not only waste fuel, but also be of great significance to improve the technical level and automation level of China's aluminum purification industry, and will also aggravate the wear of the transmission system

IV. during operation, the throttle should be increased or decreased according to the road conditions and actual needs. The selected gear should be appropriate so that its error should not exceed ± 0.5%. The engine runs at medium speed and large throttle most of the time to save fuel. When shifting gears, the coordination of filling empty oil, stepping on the clutch and stepping on the accelerator pedal should be coordinated

v. do not step on the accelerator pedal when going uphill. Do not press the accelerator pedal to the bottom when rushing the slope. When using low gear, it is generally advisable to step down the accelerator by half. During driving, if the accelerator pedal is depressed by three quarters and the engine still cannot increase the speed correspondingly, it is necessary to shift to the lower gear, and then press the accelerator pedal to accelerate

VI. turn off the throttle during maintenance. When maintaining the locomotive, rotate the crankshaft. At this time, if the accelerator is not closed, the fuel injector will continuously inject fuel into the cylinder, which not only wastes fuel, but also part of the fuel flows into the oil pan along the cylinder wall, diluting the oil and accelerating the wear of the parts
