Precautions and Taboos for Self-maintenance of Generator Sets

When the generator set fails, it must be repaired in time. If the user has professional maintenance personnel, they can repair it by themselves, but there are many precautions and taboos for the maintenance of the generator set, please pay attention to the following:

1. After the maintenance taboo is forgotten, hidden faults occur frequently. When repairing the generator set, some maintenance personnel do not understand some problems that should be paid attention to in the maintenance, which leads to "habitual" errors in disassembly and assembly, which affects the maintenance quality of the machine. For example, when installing the piston pin, the piston pin is directly driven into the pin hole without heating the piston, resulting in increased piston deformation and increased ovality: excessive scraping of the bearing bush during maintenance, the friction-reducing alloy layer on the surface of the bearing bush is scraped off, resulting in the bearing bush The direct friction between the steel back and the crankshaft causes early wear; when disassembling the bearing, pulley and other interference fit parts, do not use the tensioner, and it is easy to cause deformation or damage to the parts; When parts such as plunger assemblies are used, the oil or wax that is sealed on the surface of the parts is burned, which will change the performance of the parts, which is not conducive to the use of the parts.

2. The quality of "small pieces" is not taken seriously, because "small" loses "big", which leads to an increase in failures. During maintenance operations, some maintenance personnel often only pay attention to the maintenance of parts such as pumps and fuel pumps, but ignore the maintenance of "small parts" such as various instruments. They believe that these "small pieces" do not affect the work of the machine, even if it is damaged, it does not matter, as long as the machine is active, it is sufficient. No one knows that it is the lack of maintenance of these "small parts" that causes early wear and tear of the machinery and shortens the service life. Such as oil filter, air filter, hydraulic oil filter, water temperature gauge, oil temperature gauge, oil pressure gauge, sensor, alarm, filter screen, grease fitting, oil return joint, cotter pin, fan used in equipment Air deflector, drive shaft bolt lock plate, etc. These "small parts" are essential for the normal operation and maintenance of the equipment, and are essential to prolong the service life of the machine large”, resulting in equipment failure.

3. Parts are not decontaminated and cleaned thoroughly, and premature damage and corrosion often occur. During maintenance, the correct removal of oil and impurities on the surface of parts is of great significance to improve the quality of repairs and prolong the service life of the machine. Failure to pay attention to strengthening the cleaning of parts, unreasonable selection of cleaning agents, and improper cleaning methods will lead to early wear and corrosive damage of parts. If the debris in the bolt holes and the sand in the hydraulic components are not completely removed, the bolt torque is insufficient, the piston ring is easily broken, the cylinder gasket is ablated, and the hydraulic components are worn in the early stage: during the overhaul, do not pay attention to removing the filter, lubricating oil passage, etc. The accumulated oil or impurities at the place will make the maintenance work incomplete and reduce the trouble-free operation time of the equipment. When cleaning parts, repair personnel must choose the correct cleaning agent.
