[Air Filter Replacement] What should I pay attention to when

[Air Filter Replacement] What should I pay attention to when maintaining the diesel air filter?

Today's tractors and agricultural transport vehicles are equipped with air filters, oil filters and diesel filters, commonly known as "three filters." The operation of the "three filters" is good or bad, which directly affects the function and service life of the initiator. Now there are quite a few drivers who do not follow the required time and rules to carry out the maintenance and protection of the "three filters", causing frequent problems in the launching machine and entering the maintenance period too early. Well, the following Jiaxing filter Xiaobian will come to analyze and analyze for us, let's take a look:

In the meantime, the air filter protection and maintenance, in addition to maintenance according to the rules of time and operational requirements, should also pay attention to the following points:

1. The height of the oil level of the fine filter should be in accordance with the specification. If the oil is too high, the oil will enter the cylinder and deposit carbon. If it is too low, the filter will be lowered to accelerate the wear.

2. For the metal mesh (wire) used in the fine filter, the diameter of the hole or wire can only be slightly smaller, can not be increased, and the filling amount should not be reduced, otherwise the filter function will be lowered.

3, the intake pipe must not have air leakage, oil change and cleaning should be carried out in the windless and dust-free local; blowing filter network should use high-pressure air, in low humidity environment, blowing direction and air into the filter The direction of the screen is reversed; when the device is installed, the direction of the creases of adjacent screens should be interspersed with each other.

4. The air-guiding grating of the air filter should be free from deformation and corrosion, and its skew point should be 30 to 45°. If it is too small, the resistance will increase, affecting the intake air. If it is too large, the airflow will be weakened, and the dust will be reduced. The surface of the blade must not be painted to prevent oxidation particles from entering the cylinder. The direction of the dust outlet should be based on the ability to discharge dust particles.

5. The ventilation mesh should be arranged in the maintenance; if the filter has a dust collecting cup, the dust particles should not exceed 1/3 of the height, otherwise it should be removed in time; the dust collecting cup should be tightly sealed, and the rubber sealing strip should not be damaged or Lost.
