What is the difference between the maintenance and repair of screw hoist


The screw hoist is a kind of hoist used in engineering projects such as river embankments and hydropower stations in reservoir irrigation areas. The maintenance and repair of screw hoist are very important, so what is the difference between the two? The editor has compiled some information:


One, the nature is different. Maintenance is carried out when the equipment is in good condition. Preventive safeguard operations are to keep the equipment in good condition. The repair is a restorative operation performed under the technical condition where the normal operation of the equipment cannot be guaranteed. It is to restore the original technical indicators of the equipment and reach the normal working condition.


Second, the content is different. Maintenance is to clean, tighten, adjust, and lubricate without changing the geometric dimensions and physical and chemical properties of the parts. Repairs need to repair the geometric dimensions and physical and chemical properties of the parts to complete.


Third, the process is different. Maintenance is external operation or partial disassembly, and parts are not identified and repaired; surface repair is assembly or complete disassembly, all parts are identified, and repaired or replaced in accordance with the technical requirements of the drawings.


Fourth, the implementation principles are different. Maintenance is carried out regularly and compulsorily (that is, must be carried out when due); while repairs are carried out as planned and required.
