First, the instrument is abnormal
When driving a tractor, you should develop a good habit of looking at the instrument and find problems on the instrument of the locomotive. This is because the instrument can indicate the operating parameters of the engine. Through this, the operator can understand the operation of the locomotive and the operation of the engine. For example: ammeter is used to indicate the battery charge and discharge current intensity of the instrument; oil pressure gauge is used to display the engine oil pressure and lubrication system operating conditions of the instrument; water temperature indicator is used to indicate the cooling water in the water jacket The temperature of the. There are many other instruments and indicators such as these. If the meter or indicator suddenly shows an abnormal condition during normal engine operation, it indicates that the vehicle is malfunctioning. Therefore, timely measures should be taken to check for troubleshooting according to the actual situation.
Second, abnormal performance
Locomotive performance generally refers to power, braking, ride comfort, fuel consumption, and so on. If in use, the locomotive performance suddenly deteriorates, it means that the locomotive has a fault and should be eliminated promptly. Abnormal conditions in the tractor's technical condition and performance, such as start-up difficulties, tractor brake failure, master clutch slippage, generator not generating power, and tractor traction being too small.
Third, abnormal sound
As a driver, he often deals with his own locomotive and is more familiar with the condition of the locomotive. Therefore, it is more sensitive to sudden abnormalities in locomotives. Therefore, we should not ignore the sudden abnormal sound of locomotives during use, and respond to abnormal noises in a timely manner to check and repair in time. If the tractor is working, abnormal knocking sounds, blasting sounds, and unusual noises occur.
Fourth, abnormal smell
If the locomotive suddenly suffers from burnt odors, excessive oily smells, and other abnormal odors during operation, the locomotive is in trouble. There will be coke odor when the clutch plate is ablazed; poor contact with the electrical circuit will cause a burning smell; too thick oil may have oil leakage, which is also very dangerous; the exhaust belt burns oil that is not completely emitted Flavor or burnt scent, etc. Therefore, it is necessary to make timely judgments based on different odors in order to eliminate the malfunction.
V. Abnormal temperature and clearance
When the locomotive is parked midway, check the condition of each part of the locomotive. Such as: touch brake hub, axle housing, transmission shell and so on. If the temperature is too high, it means there is a fault. And pay attention to check whether the free travel of the clutch pedal, the free travel of the brake pedal, the free travel of the steering wheel, etc. meet the standard values. At the same time, pay attention to checking the sealing of each connecting part to see if there is leakage. Once leaks, leakages, oil leaks, or leaks are found, they should be promptly removed.
Six, the old and new contrast method
The long-term use of their own locomotives, in the gradual change process, the slow changes in the mechanical performance of the locomotive does not feel obvious, especially for the steering mechanism, brake mechanism, transmission mechanism, locomotive power performance and acceleration performance, etc. The bad feeling is not obvious. In this way, the driver can compare the new cars of the same type by trial. It is not difficult to find where the car is short of and where the fault is.
Seven, abnormal consumption
Excessive consumption of diesel, oil, and cooling water.
Eight, the appearance of abnormal
If the exhaust pipe emits white smoke, black smoke or blue smoke, there are oil leakage, leakage, leakage and air leakage everywhere, the light is not bright, the parts or components are in disorder, and the readings of various meters exceed the normal range.
The operator should pay attention to the daily maintenance of the locomotive and find the problem from the abnormal situation in the above aspects as soon as possible, and solve the problem in time so as to reduce unnecessary economic losses and avoid traffic accidents.
