1. Air cleaner maintenance points. In addition to air filters in accordance with the time and operational requirements of the instructions and maintenance requirements, we should also pay attention to the following points:
(1) The air filter grate should be kept free from deformation and rust. Its inclination angle should be 30-45?#65292; when it is too small, the resistance will increase, affecting the air intake, if it is too large, the air flow will decrease. The ability to separate dust is 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.
(2) Maintenance should be cleared through ventilation mesh; for dust cups, dust particles should not exceed 1/3 of the height, otherwise it should be promptly removed; dust collection cup mouth should be tightly sealed, rubber seals must not be damaged or lost .
(3) The height of the fine filter oil surface should be in compliance with the standard. If the oil is too high, it will cause the oil to enter the cylinder and deposit carbon. If it is too low, the filter effect will be reduced and the wear will be accelerated.
(4) For the metal mesh (silk) in the fine filter, the diameter of the hole or wire can only be slightly smaller and can not be increased. The filling amount must not be reduced, otherwise the filtering effect will be reduced.
(5) There must be no air leakage in the air inlet line. Change oil and cleaning should be done in a place without wind and dust; blow the filter mesh to use high-pressure air, perform in a low-humidity environment, and insufflate the air into the filter. The direction of the opposite; when installed, the adjacent filter fold lines should cross each other.
2. Oil filter maintenance points. The oil filter must be maintained according to the specified time, and pay attention to the following points:
Centrifugal oil filter. Maintenance of centrifugal fine filter should pay special attention to the installation after removal: 1 should not block phenomenon. The inspection method is that when the rotor is reassembled, the rotor is forced to rotate by hand. After the release, the rotor can be stopped after 2-3 revolutions freely, that is, it is qualified; 2 The fine filter can also be installed in the car, and the engine is started. Running for a few minutes at the speed, when the oil temperature reaches 70°C, it will be extinguished. At this time, the rotor will continue to rotate while outside the casing. It can reach more than 1.5 minutes, which means it is qualified for installation. If the above index is not met, it means that the installation failed and should be re-assembled.
