What are the requirements for disassembling the device

Remember the order of disassembly and keep a record.

Principles of disassembly of equipment.

Sequence principle: According to the experience of equipment handling, the general order of equipment disassembly is first small and then large, first ground and then high-altitude, first simple and then complex. For batch equipment disassembly, the near equipment should be disassembled first, and then the distant equipment should be disassembled.

Principle of convenience: After most of the equipment is disassembled, it needs to be packaged or reinstalled, and only a few equipment may be eliminated and do not need follow-up work. Therefore, for most of the equipment, when dismantling, it is necessary to take into account the factors of packaging and installation, and strive to provide convenience for packaging and installation.

What can be dismantled can be dismantled, and what can be dismantled or not dismantled should not be dismantled as much as possible.

Prohibition principle: In the disassembly of equipment, it is forbidden to use tools and disassembly methods that destroy equipment, such as prohibiting gas cutting equipment, prohibiting the use of heavy hammers and other equipment, and prohibiting damage to equipment.

Tips for disassembling equipment.

Pioneer the mark. Some devices have high requirements for installation positions, and the installation position and distance between different components are fixed. For this kind of disassembly task, it is necessary to mark the location of various types of equipment before dismantling and record it to provide basic information for the installation of equipment.

The parts are placed according to the smooth stacking. The parts disassembled from the equipment need to be stacked in the order of disassembly, and the order should not be disturbed as much as possible during the packaging and transportation, and the number and order of the parts should be recorded in writing.

Try device videography. In order to facilitate the installation, before or during the dismantling of the equipment, the disassembly process can be recorded or photographed, so that there is a reference basis for installation.

Of course, for equipment handling and equipment disassembly, the most familiar is the technical personnel of the equipment, so the disassembly of equipment should require the presence of technical personnel in order to provide timely assistance, which can also greatly improve the efficiency of equipment lifting.

1. Understand the internal transmission principle and assembly relationship of mechanical equipment;

2. The principle that the disassembly process is opposite to the assembly process;

3. In case of abnormal situation, find the reason, and do not allow destructive disassembly;

4. When disassembling large parts, pay attention to the safety and acceptance of differences, and require the parts to be suspended in advance (through the center of gravity);

5. It is necessary to record when disassembling the lead skin of the hole, and the disassembled parts are placed in an orderly manner to prepare for reinstallation.

Device disassembly and assembly steps:

Full preparation: Before disassembly, it is necessary to be familiar with the structure and working principle of the equipment according to the requirements of the equipment instruction manual, understand the role and interrelationship of each part and components, analyze the structure, position and assembly and disassembly of each part and the component to avoid blind disassembly; Determine the specific disassembly part: decide the disassembled parts and components from the actual situation to avoid unnecessary disassembly; However, the parts that do not need to be disassembled should also be carefully analyzed and inspected to avoid leaving hidden dangers and causing adverse consequences; Take the right approach to disassembly:

The disassembly work should be carried out in a certain order, and the disassembly order is opposite to the assembly order, first dismantling the external accessories, and then disassembling according to the parts and components; When disassembling parts or assemblies, they should be carried out in the order of first outer and then inside, first up and then down; Precautions for disassembly: The convenience of repair and assembly should be fully considered when disassembling, and corresponding measures should be taken after the equipment is disassembled. Equipment disassembly and assembly principle:

Pre-demolition inspection; diagnostic operation; develop a plan for modifications; parts disassembly and cleaning; Replacement options for parts.

Principles of dismantling of machinery and equipmentThe disassembly work has a great relationship with the quality of mechanical equipment repair, such as improper disassembly, which will not only cause damage to equipment parts, but also affect the accuracy of mechanical equipment after repair. Therefore, the principle of disassembly must be followed when repairing, and the correct disassembly method must be taken.

1 Be prepared.

Before disassembly, it is necessary to be familiar with the structure and working principle of the equipment according to the requirements of the equipment instruction manual, understand the role and interrelationship of each component and component, analyze the structure, location and assembly and disassembly method of each component and component, and avoid blind disassembly.

2. Determine the specific disassembly part.

Decide the parts and components to be disassembled from the actual situation to avoid unnecessary disassembly. However, the parts that do not need to be disassembled should also be carefully analyzed and inspected to avoid leaving hidden dangers and causing adverse consequences;

3 Adopt the correct method of disassembly.

The disassembly work should be carried out in a certain order, and the disassembly order is opposite to the assembly order, first dismantling the external accessories, and then disassembling according to the parts and components; When disassembling parts or assemblies, they should be carried out in the order of first outer and then inside, first up and then down; Tools and equipment should be reasonably selected when disassembling, and it is strictly forbidden to knock and beat indiscriminately.

The tools used must be adapted to the part being disassembled.

4 Precautions for disassembly.

The convenience of repair and assembly should be fully considered when dismantling, and corresponding measures should be taken after the equipment is disassembled

1) For some parts and components with high manufacturing precision, measures such as group selection, error compensation or single piece grinding and research should be taken during the original manufacturing, and the corresponding positions of the parts should be marked on the zero and parts before disassembly.

2) The removed parts should be cleaned or degreased in time, and placed separately in an orderly and regular manner, and the shaft assembly with more parts should be disassembled and started with iron wire in the original assembly order.

3) Remove the precision parts that have been finely machined, clean and oil them and store them separately. After the slender precision parts are cleaned and oiled, they should be lifted vertically with ropes to prevent deformation or bruising.

4) Remove the hydraulic and pneumatic components and conduits, etc., and seal them after cleaning to prevent dust or debris from entering. To disassemble the hydraulic pipeline, the paired pipe ends should be numbered accordingly.

Second

a. According to the model and relevant information, the structural characteristics and assembly relationship can be clear, and then the method and steps of disassembly and disassembly can be determined.

B, the correct selection of tools and equipment, when the decomposition encounters difficulties, to find out the cause, take appropriate methods to solve, do not allow slamming to prevent damage to parts and tools, but also can not use measuring tools, pliers instead of hammer and cause damage.

c. When disassembling parts or assemblies with specified directions and marks, the direction and marks should be remembered, and if the marks are lost, they should be re-marked.

d. In order to avoid damage or loss of the removed parts, they should be stored separately according to the size and accuracy of the parts, placed in the order of disassembly, and the precision important parts should be stored for safekeeping.

e. The removed bolts, nuts, etc. should be installed back in place without affecting the repair, so as to avoid loss and facilitate assembly.

F, disassembly on demand, for individual can not be disassembled to judge its good condition can not be disassembled, on the one hand, it can save time and labor, on the other hand, it can avoid damage in the process of disassembly and assembly and reduce the accuracy of parts assembly. However, the parts that need to be disassembled must be disassembled, and the repair quality cannot be guaranteed in order to save trouble.
