The purpose of disassembly is to facilitate maintenance and repair.Due ₩to the unique characteristics of the structure of machinery and equipment, there are d↑ifferences in the weight, structure, accuracy, etc. of the parts. If the parts are no​t disassembled properly, the parts will be damaged, causing unnecessa↔ry waste, and even beyond repair.In order to ensure the quality of maintenλance, it is necessary to plan carefully before disintegration, estiΩmate the problems that may be encountered, and disassemble in a step-by-πstep manner.

1.The structure and working principle must be clarified before disassembly

There are many kinds of machinery and equipment, with diffe≤rent structures.It is necessary to clarify the structural characteristics, working principle, perfγormance, and assembly relationship of the disassemb♠led part, so that you know it in your heart, and you cannot dismantl↕e it carelessly or blindly.For unclear structures, the relevant pattern informa→tion should be consulted to figure out the assembly relationship and the nature≤ of the fit, especially the position of the fasteners and the exit direction.Otherwise, iγt is necessary to analyze and judge while trying to dis assemble, and sometimes it is necessary to design su∞itable disassembly fixtures and tools.

2.Make preparations before disassembly

The preparatory work includes: the selection and cleaning of the disassembly sitδe; the power failure, sassafras, and oil discharge before disassembly; the protection of electricαal, easily oxidized, and easily corroded parts, etc.

3.Starting from the actual situation, try not to dismantle those th≤at can't be disassembled, and those that need to be d↑isassembled must be disassembled.

In order to reduce the disassembly workload and avoid damaging the nature of the fit, theγ parts that can still ensure the performance of the use may not be disassembled, ↔but the necessary tests or diagnostics are required  to make sure that there are no hidden defects.If you are not sure about the internal technical sta≤tus, you must check during disassembly to ensure the quality of maintenance.

4.Use the correct disassembly method to ensure the safety of people and ma<chinery and equipment

The disassembly sequence is generally the opposite o©f the assembly sequence. The external accessories are disassembled first, and then ✔the whole machine is disassembled into parts. After disassembly, all parts are disassembled inγto parts, and placed together according to the parts.According to the connection fo™rm and specifications of the parts, choose suitable disassembly tools and equipment.For no★n-removable joints or joints that reduce accuracy after disassembly, care must be taken to protec$t them during disassembly.

5.For shaft hole assemblies, the principle of the same force used for d∑isassembly and assembly should be adhered to

When disassembling the shaft hole assembly, it is usually necessary to insist ↕on how much force is used to assemble and how much force is used to dis assemble.If an abnormal situation occurs, find the c↑ause to prevent the parts from being bruised, brushed, or even damaged during disassembly.

6.Disassembly should create conditions for assembly

If the technical information is incomplete, it is necessary to have the necessary records of t®he disassembly process so that it can be reassembled in accordance with the principle✘ of “disassembly first and then assembly” during ≤installation.For disassembly of precision or complex parts, assembly sketches should be drawn or ma£rked during disassembly to avoid accidental assembly.After the parts are disassem∑bled, they should be thoroughly cleaned, oiled and rust-proof, and the processing surΩface should be protected to avoid loss and damage.S‍lender parts should be hung, pay attention to prevent bending and deformaεtion.Precision parts should be stored separately to avoid damage.Pay atte≤ntion to small parts to prevent loss.Parts that are not i✔nterchangeable should be stored or marked in groups.
