Summary: When you have noticed machinery equipment maintenance quality problems do the production activities, equipment maintenance is an important measure to protect the safe operation of equipment; the recovery equipment technical performance, troubleshoot and eliminate hidden faults, extend equipment effective means of life. Our equipment maintenance industry started relatively late, in the service, there are still many technical problems. These problems can cause mechanical equipment maintenance quality is not high, poor equipment reliability, even major equipment accidents. 1, "a small piece" good or bad does not pay attention, because of "small" lost "big" lead to failure increases.
When using a mechanical device that you have paid attention to the quality of equipment maintenance problems it
The production activities, equipment maintenance is an important measure to protect the safe operation of equipment; the recovery equipment technical performance, troubleshoot and eliminate hidden faults, an effective means to extend the life of equipment. Our equipment maintenance industry started relatively late, in the service, there are still many technical problems. These problems can cause mechanical equipment maintenance quality is not high, poor equipment reliability, even major equipment accidents.
1, "a small piece" good or bad does not pay attention, because of "small" lost "big" lead to failure increases.
When equipment maintenance operations, some maintenance personnel are often only concerned about maintaining pumps, fuel pumps and other components, but they ignore all kinds of instruments, such as "a small piece" of maintenance. They believe that these "little pieces" do not affect the mechanical work, even if damage does not matter, as long as you make do with mechanical active. I do not know exactly what those called, pieces of "lack of maintenance, resulting in the occurrence of early mechanical wear and shorten life such as equipment used oil filters, air filters, hydraulic oil filters, water temperature, oil temperature, oil pressure gauge, sensors, alarms, filters, grease fittings, oil return fitting, cotter pins, fan wind shield, drive shaft bolt locking plate, etc., which this "small pieces" is the device is working properly and maintenance essential of vital extend the life of machinery, such as pay attention to maintenance, often "runs the risk", leading to equipment failure.
2. Maintenance taboo forget the back, hidden failures frequently out.
Maintenance equipment, maintenance personnel do not understand some of the problems that some maintenance should be noted, resulting in frequent disassembly "habitual" errors, affecting the quality of maintenance of machinery. Such as when installing piston pins, piston directly without heating the piston pin into the pin hole, resulting in deformation of the piston increases, increasing the ovality: When servicing diesel generator excessive scraping Bush, anti-friction bearing alloy layer is scraped off the surface led directly to the crankshaft bearing steel back early friction and wear; dismounting bearings, pulleys and other chest when not in use over an interference fit parts, hard to play hard knocks, easily lead to deformed or damaged parts; unsealed new piston, cylinder, fuel injection when the nozzle assembly, plunger assembly and other parts, parts of the surface sealed with fire oily or waxy that part performance changes, is not conducive to the use of parts.
3, parts decontamination, cleaning is not complete, early loss, corrosion often occurs.
When servicing equipment, properly remove oil component surface impurities to improve the quality of repairs and extend machine life of great significance. Pay attention to strengthening the parts cleaning, cleaning agents choose unreasonable, improper cleaning methods will lead to early component wear, corrosion damage occurred. If you do not completely remove the bolt hole country debris, sand hydraulic components, resulting in insufficient bolt torque, easily broken piston rings, cylinder head gasket ablation, early wear of hydraulic components: overhaul, pay attention to remove filters, lubricating oil passages, etc. at the accumulation of oil or impurities, so that maintenance work is not complete, reducing equipment uptime.
Repair personnel in the cleaning parts, one should choose the right cleaning agents. For cleaning a variety of components, should be based on their different requirements for cleanliness, proper selection Wei different cleaning agents; two parts to prevent corrosion and rust. To ensure the quality of the parts, components should prevent mildew rust corrosion, especially for precision parts but not allowed to have any degree of corrosion or rust. Therefore, when cleaning is unavailable alkaline cleaner (especially alkali cleaners) to clean aluminum parts category, but not with strong acid cleaning agent copper-based components to minimize corrosion of parts; the third is should be classified in different parts cleaning. Aluminum class parts, copper-based components should not be placed in an alkaline or acidic cleaners together to clean, rubber parts and other iron and steel parts should not be placed on gasoline and diesel fuel and acid, alkaline cleaner cleaning together
According to the law of the equipment, often improve equipment maintenance, extend the normal use of the stage parts; the equipment necessary checks, to grasp the equipment in order to take appropriate way to repair the problem before the parts into the device. |
