Precautions and Taboos for Self-maintenance of Generator Sets
by Starlight Generator dieselgeneratortechWhen 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 largeā, 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.
Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets
in China. If you want get more information, please feel free to send
