Method for reducing wear of agricultural instrument parts
Wear: Parts wear increases as working time increases. There are three different periods of wear and tear during the run-in period, ie, the wear-on period, the stable wear period, and the severe wear period.
Running-in period - newly assembled parts, due to the roughness and geometrical deviation of the surface, the actual contact area between the parts is small, the load per unit area is large, the oil film is difficult to maintain and the wear is strong, after the running-in according to the running-in specification, the surface The state enters the state required for the working condition, and the wear rate is lowered.
Stable wear period - the amount of wear on the part increases in proportion to the working time and is generally slow. However, when the use and maintenance are not elaborate and the working conditions are bad, the wear of the parts may still be strong.
Severe wear period - the wear of the parts is accumulated, the gap between the parts is increased, the impact load is increased, the lubricating oil film is difficult to form, and the parts are accelerated and worn, and should be repaired or replaced in time.
Measures to reduce wear on parts are:
1. Each lubricating part has clean and sufficient grease lubrication.
2. Filtering of air and fuel to prevent abrasive from entering the machine.
3. Avoid overloading the machine.
4, the tractor to minimize the number of starts, especially today. Do not use traction tractor to walk and start to reduce shaft and tile wear.
5. The working temperature of the engine should be kept normal.
6, timely maintenance, adjustment.
