The starting devices of rural tractors and agricultural transport vehicles are equipped with air filters, oil filters and diesel filters, commonly known as "three filters". The operation of "three filters" directly affects the operation function and service life of the starter. At present, quite a lot of drivers fail to maintain and protect the "three filters" according to the prescribed time and rules, resulting in frequent engine failures and premature entry into the maintenance period. Let's take a look at it next.
The maintenance master reminds you: the protection and maintenance of the air filter, in addition to the regular and operation and maintenance requirements, should also pay attention to the following points:
1. The guide grille of the air filter should not be deformed or rusted, and its inclination angle should be 30-45 degrees. If the resistance is too small, it will increase and affect airflow. If the airflow is too large, the rotation of the airflow will be weakened and the separation from dust will be reduced. The outer surfaces of the blades do not need to be painted to prevent oxidation particles from entering the cylinder.
2. The ventilation mesh should be cleaned during maintenance. If the filter has a dust cup, the dust particle height should not exceed 1/3, otherwise it should be removed in time; the dust cup mouth should be tightly sealed, and the rubber seal should not be damaged or discard.
3. The height of the oil level of the filter should meet the standard requirements. If the oil level is too high, it will cause carbon deposits in the cylinder. Too low oil reduces the filter's function and accelerates its wear.
4. When the metal mesh (wire) in the filter is replaced, the diameter of the hole or wire can only be slightly smaller, and the filling capacity cannot be increased. Otherwise, the functionality of the filter will be reduced.
Pay attention to the air leakage of the intake pipe, and the oil change and cleaning should be carried out in a place without wind and dust; the fan filter should be carried out in an environment with low humidity and high pressure air, and the blowing direction should be opposite to the air entering the filter screen; during installation, The folding directions of adjacent filters of Di should penetrate each other.
