What are the daily faults of the tractor? The tractor is used for the self-propelled power machine which is used for the traction and driving working machinery to complete all kinds of mobile operation. It can also be used to fix the working power. It is composed of engine, transmission, walking, steering, hydraulic suspension, power output, electrical instrument, driving control and traction system or device. Today, the editor will explain to you what its daily faults are:

1. high pressure oil pipe is worn and leaking

If there is wear and oil leakage at the connection between the convex head of the high-pressure oil pipe and the injector and the oil outlet valve of the tractor, the small hole friction pad can be cut off from the waste cylinder pad and a small hole is cut off from the waste cylinder pad to solve the urgent problem.

2. emergency oil supply is insufficient

The fuel supply shortage in tractor operation is not effective after air is removed, plunger is replaced and injector is still ineffective. That is, the small steel ball in the ejector rod of injector is worn out so that the fuel injection can not be atomized. At this time, replace with one small steel ball or replace with bicycle flywheel steel ball.

3. shaking of steering wheel and front wheel swinging

The main reason for the steering wheel shaking and shaking of the front wheel is that the caster angle of the main pin is too small due to the improper front wheel positioning. In the absence of instrument detection, it is necessary to try to add wedge-shaped iron sheet at the back of the flat end of the steel plate spring and front axle support to make the front axle turn backward and then increase the caster angle of the main pin to return to normal after trial operation.

4. automatic shifting after changing speed

The phenomenon of automatic shifting occurs after the tractor changes speed, which is mainly caused by the wear of the fork shaft groove, the weakening of the fork pulling spring and the excessive clearance of the connecting rod joint. At this time, the normal speed can be ensured after repairing the positioning groove, replacing the fork spring and reducing the clearance of the connecting rod joint.

5. poor performance of oil pump

To solve the problem that the oil pump performance is poor after overhaul or overhaul, the oil filter or oil outlet pipe can be removed and then filled with oil from the oil outlet hole of the engine body with oil injector. The oil will be pumped up after the oil pipe leading to the oil indicator is started.

6. fatigue damage of hydraulic oil pipe

The frequent oil pressure change and high oil temperature make the wall relaxation frequent and easy to occur fatigue damage and lead to accidents. In order to extend the service life of hydraulic oil pipe, the fine wire is used to burn into spring shape and put into the pipe for support.

7. brake failure of hydraulic brake locomotive

Carefully check the brake master cylinder and sub pump to see if the brake oil has been replaced on time and the air in the brake line is completely eliminated and whether the brake pedal conforms to the scientific height.

8. the diesel engine burns oil and emits blue smoke

If the cause of blue smoke is still coming out, it is necessary to check whether the valve rod and valve guide pipe have too much clearance.

9. excessive engine temperature caused by excessive scale

The engine cooling pump scale will cause the engine temperature too high, accelerate the parts wear and reduce the power consumption of the lubricating pump oil. The elimination method is: select 2 big melons to remove the scale after removing skin and cleaning seeds and then put them into the water tank for regular replacement. The water in the water tank should not be changed frequently, which will increase the formation of scale.
