Agricultural machinery repair and dismantling essentials
The maintenance of agricultural machinery is often carried out during dismantling and installation. Due to the different types and structures of the machinery, if the hard equipment is disassembled, the agricultural machinery will be easily damaged. Therefore, when disassembling and installing, follow the following procedures strictly.
First, disassemble
1. The operating procedures should be considered in advance according to the structure of the agricultural machine so as to avoid successive inversions.
2. When dismantling, it should be done from outside to inside and from top to bottom.
3. Special tools should be used during operation. It is forbidden to hit the part directly with a hammer.
4. To find out the direction of loosening the parts, care should be taken with precision parts. For example, the long shaft parts of the pole must be lifted with a rope and wrapped with cloth to prevent bending deformation and damage.
5. The removed parts should be placed on wooden racks, wooden boxes or parts trays as required, and must not be placed on the ground to prevent damage and corrosion.
6. The removed parts should be put together as far as possible in the original structure, such as shafts, gears, screws, gaskets, positioning pins and so on.
7. For complete sets or parts that cannot be exchanged, mark them before disassembly and string them together to avoid mixing, such as gear sets, valves and valves, etc. Valve fittings should be plugged into the original valve body.
8. Components that can still be used without repairs should not be disassembled and thrown loose, such as splines and gears, shafts, and bearings.
9. To facilitate the inspection of parts, the removed parts should be cleaned as necessary and then coated with engine oil to prevent rust.
Second, install
1. During assembly, from inside to outside and from top to bottom, the principle of the next process is not affected.
2. The operation must be serious, and important complex parts should be checked repeatedly to avoid mis-installation and missing-loading.
3. Do not allow dirt into the component.
4. During the installation process, inspections should be made in strict accordance with the technical requirements.
5. The assembled machine must be adjusted and commissioned.
