First, agricultural machinery failure prediction

In the spring ploughing production process of farm machinery, if a mechanical failure occurs, light traffic accidents result, the person is injured, the vehicle is damaged, and the vehicle is destroyed. How to predict the failure of the tractor to avoid accidents?

1, shape prediction

By observing the shape of the tractor, if there is any abnormality, such as the tractor is parked on a flat road with an inclination, the tire has abnormal wear, scratches, and parts are lost, the agricultural hand should be vigilant.

2. Leakage prediction

For example, if the sealing performance of some parts of the tractor deteriorates, water leakage, air leakage, oil leakage, and electrical leakage occur.

3, fuel consumption forecast

Various fuel consumptions of tractors have standard ranges. If there is a significant increase in fuel consumption, it indicates that the tractor has hidden faults.

4. Sound prediction

If some parts of the tractor rattle during operation, the part is faulty.

5. Clearance prediction

The clearances of all parts of the tractor have their standard values. If the clearance is too large or too small, it means there is a fault.

6. Odor prediction

When driving, if you smell an abnormal smell (burnt smell, etc.), it means that the car is malfunctioning.

7, temperature forecast

Feeling excessive temperature in driving, or stopping inspection midway, touching the temperature of each part of the vehicle is not normal, such as touching the brake drum, tires, rear axle housing, transmission shell, etc., the temperature makes the hand unbearable, which indicates that the tractor exists malfunction.

8, performance prediction

The various performance of the tractor will decrease with the increase of driving mileage, but it is slow and should not be felt. If the performance suddenly deteriorates during driving, it indicates that there is a fault (such as the rapid decline of engine power performance, brake failure, etc.). ).

Second, the maintenance and maintenance of agricultural machinery in the spring plowing

Agricultural machinery plays an important role in the production of spring plowing. How to maintain agricultural machinery, reduce maintenance errors, and prolong the service life of agricultural implements are common concerns for farmers. Here are some common mistakes in the maintenance of agricultural machinery. Everyone's attention introduces unnecessary losses.

1. Oil sump oil depends only on quantity, not quality. Some drivers only know how to supplement the oil and ignore the quality check. Little do they know that long-term use of oil contains a large number of oxides and metal shavings, resulting in reduced lubricating properties, parts wear increased.

2, only maintenance of air filter, maintenance of exhaust pipe and muffler. Some drivers never clear the carbon deposits in the exhaust ducts and mufflers, resulting in excessive carbon deposits, reduced cross-sectional area of ​​exhaust gas, exhaust gas exhausts, insufficient fresh air, and poor combustion.

3, cooling water just add, regardless of cooling effect. Some drivers never remove scale. Although the cooling water is sufficient, the cooling effect is poor.

4. Pay attention only to the quality of the plunger coupler and the injector needle valve assembly, and pay attention to the quality of the outlet valve assembly. One of the functions of the oil valve is sealing, that is to say, the plunger oil chamber is separated from the high-pressure fuel pipe to prevent backflow; the second is to quickly depressurize when the oil supply is stopped, so as to ensure that the fuel injector is cut off and brittle. Even if the delivery valve is of poor quality or worn out, it will cause many diesel engine failures.

5, only pay attention to the state of the valve and valve seat, do not pay attention to the quality of the valve spring. When the valve is leaking, people often only check the valve and valve seat, and ignore the valve spring quality inspection.
