Principle analysis of common faults of diesel generator maintenance work incentives
I. generator troubleshooting
To ensure reliable unit operation and performance, is important to carry out regular inspection and, if necessary, maintenance, organized maintenance plans, need to develop a schedule or time scheduled for periodic inspection and test list. It must be emphasized that following maintenance instructions are only for the General case, because of the variety of generator models, specific maintenance requirements for any unit, required reference the provided instructions.
Common faults of diesel generator note the following several points:
1. the generators not start because
(1) check whether the battery voltage rated voltage DC48V
(2) check the battery post and the connection cable is bad.
(3) positive and negative pole cable starter motor wire be loose wiring because vibrates when the generator is running the wiring loose cause poor contact.
(4) due to air in the fuel system.
2. high cooling water temperature fault
(1) usually is cooling water box radiator surface does not clean caused cooling water box within cooling liquid insufficient, generator in using more long time Hou cooling fan of belt will gradually aging became without elastic or a article belt fracture caused cooling fan lost normal of hair dryer capacity, then needed again replaced cooling fan of belt, replaced Shi should whole group belt together replaced and not only for which of a a article.
(2) cooling water cooling water pump failure will not cycle and increase the water temperature, is because of a thermostat failure can not open, circular path of cooling water does not change when cooling water temperature, control entry to the radiator cooling flow, achieve adjusting cooling strength of purpose, need to replace the thermostat.
(3) the use of unqualified cooling water pipes of cooling liquid product such as scale, rust, and so impede the circulation of cooling water temperature caused by.
3. generator exhaust black smoke
(1) use poor-quality fuel, containing impurities.
(2) environmental dust debris, serious air filter clogging.
(3) fuel injection timing of the engine does not.
4. the generator exhaust to risk blue smoke
Are generally too much oil in the filter (adding too many maintenance timing oil) caused reduced oil to provide liquid can be resolved. Another situation is that stuck or excessive wear of piston rings, elastic due to the lack of oil leaking into the combustion chamber the burning. This needs to be cleaned or replace the leaking part of piston ring piston rings.
5. the generator exhaust white smoke risk
(1) contains water in the fuel system causing. Can storage Department of bottom emission, viewing with or without water.
(2) the cylinder valve worn on air change now white smoke exhaust smoke rings. You must to replace worn parts.
(3) poor injector fuel injection spray, diesel fuel droplets in the combustion chamber is not burning. Nozzle must be checked, adjusted to the provisions of fuel injection pressures.
II. the daily maintenance of the generator maintenance
In order to get maximum operational safety and the use of unit life, regular maintenance is necessary on unit, if they can comply with the regulations unit maintenance, you can guarantee the performance of the unit.
(1) daily maintenance:
1, check the diesel generator working daily.
2, check the diesel generator: engine oil plane, cooling liquid plane.
Day 3, found mixed with diesel generators for damage, leakage, the belt is loose or worn.
(2) the weekly maintenance:
1, repeat class a diesel generator to check on a daily basis.
2, check the air filter, clean or replace the air filter element child.
3, release the water in the fuel tank and fuel filter or sediment.
4, check the water filter.
5, check the starter battery.
6, starting of diesel generators and check for effect.
7, wash with air gun and water cooler before and after the end of the heatsink.
(3) the organization maintains
Organized maintenance workload and costs to a minimum level, because it is organized regularly, rather than request only if the unit is in a State of emergency, other benefits of regular maintenance may not be clearly seen, due to potential failures may be found to its development, which saves repair costs. At the same time, since the unit always running in an optimal state, will reduce operating costs and increase machine life.
(4) maintenance program
Recommends that the persons responsible for the maintenance, inspection and maintenance time, or schedule of developed generator, summarizing all the appropriate cycle parts of the attention. This reduces duplication of similar projects, so that the unit stop time at least, deeper advantage is that these dead time arrangements can be adjusted at the time of least impact on regular on-site activities, usually the engine or the main moving parts, require constant attention, and recommends that all maintenance cycle should be based on the engine's requirements. Each manufacturer of engines provide clear, detailed descriptions of the equipment maintenance, as well as necessary for its maintenance cycle. It must be noted that engine manufacturers to provide maintenance intervals based on the room environment clean and dry. If the unit is running in dirty and/or humid environments, maintains should be more frequent, engine and generator maintenance procedures at its shown in the manual, should watch these maintenance procedures, and content in this section.
