How Often Does the Backup Power Diesel Generator Set Be Maintained

Oct. 15, 2021

How often is the backup power diesel generator set to be maintained? The first time it runs for about 80 hours or one year after leaving the factory, it must be maintained.

 

Diesel generator sets are the providers of emergency backup power after mains failure and power failure. Most of the time, the generator sets are in standby standby state. Once the power fails, the generator sets are required to [start in time and supply power in time] otherwise the standby unit will lose its meaning.

 

Dingbo Power reminds you: Strengthening routine maintenance is the most economical and effective way. Because the unit is in a static state for a long time, the various materials of the unit itself will undergo complex chemical and physical changes with oil, cooling water, diesel, air, etc., so that the unit "Downtime". The following are eight parts that must be checked regularly:

 

1. Parts need to be replaced.

 

(1). Engine oil.

 

The engine oil is mechanically lubricated, and the oil also has a certain retention period. When stored for a long time, the physical and chemical properties of the oil will change, which will cause the deterioration of the lubrication condition of the unit when it is working, and it will easily cause damage to the unit parts. Therefore, it needs to be replaced once a year.

 

(2). Filter.

 

The filter refers to diesel filter, machine filter, air filter, water filter, which filters diesel, oil or water to prevent impurities from entering the body. In diesel oil, oil and impurities are also unavoidable, so the unit is running In the process, the filter plays an important role, but at the same time, these oil stains or impurities are deposited on the wall of the filter screen, which reduces the filter capacity of the filter. If the deposit is too much, the oil circuit will not be unblocked. It will be shocked due to the lack of oil supply (like a person lacking oxygen), so during the normal use of the generator set, we recommend:

 

Commonly used units replace the three filters every 500 hours.

 

The standby unit replaces the three filters every year.

 

(3) . Antifreeze.

 

Antifreeze is an indispensable heat dissipation medium for the normal operation of electric generator. One is to prevent freezing of the water tank of the unit, which will not freeze and expand and burst in winter; the other is to cool the engine. When the engine is running, use antifreeze as a circulating cooling liquid effect It is clear. The antifreeze that is not used for a long time is easy to oxidize in contact with the air, which affects the antifreeze performance, so it needs to be replaced once a year.

2. Need to check:

 

(1). Unit start battery

 

The battery is unmaintained for a long time, and the electrolyte cannot be replenished in time after the water evaporates. The battery charger is not equipped to start the battery. After the battery is discharged for a long time, the power is reduced, or the charger used needs to be manually equalized and floated. Due to negligence and failure to perform the switching operation, the battery power cannot meet the requirements. In addition to the configuration of high-quality chargers, necessary inspection and maintenance are necessary to solve this problem.

 

(2). Water enters the diesel engine.

 

As water vapor in the air condenses due to temperature changes, it forms water droplets that hang on the inner wall of the fuel tank and flow into the diesel fuel, causing the water content of the diesel fuel to exceed the standard. Such diesel fuel enters the high-pressure oil pump of the engine and will rust the precision coupling parts ----- Plunger, serious damage to the unit, regular maintenance is effective and can be avoided.

 

(3). Lubrication system, seals.

 

Due to the chemical properties of lubricating oil or oil ester and the iron filings produced after mechanical wear, these not only reduce its lubricating effect, but also accelerate the damage of the parts. At the same time, the lubricating oil has a certain corrosive effect on the rubber sealing ring. In addition, the oil seal It also deteriorates due to its aging at any time.

 

(4). Fuel and gas distribution system.

 

The output of engine power is mainly the fuel burned in the cylinder to do work and the fuel is sprayed through the fuel injector, which makes the burnt carbon deposit deposited on the fuel injector. As the deposit volume increases, the fuel injection volume of the fuel injector will be affected. A certain influence, leading to the inaccurate timing of the ignition advance angle of the fuel injector, the uneven fuel injection of each cylinder of the engine, and the uneven working state. Therefore, the fuel system is cleaned regularly and the fuel supply is smooth when the filter components are replaced. The adjustment of the gas distribution system makes it evenly ignite.

 

(5). The control part of the unit.

 

The control part of the unit is also an important part of the unit maintenance. The unit is used for too long, the line connector is loose, and the AVR module is working properly.

 

(6). Cooling system.

 

If the water pump, water tank and water pipeline are not cleaned for a long time, the water circulation is not smooth, the cooling effect is reduced, whether the water pipe joints are good, the water tank, and the water channel are leaking, etc. If the cooling system fails, the consequences are as follows:

 

The cooling effect is not good and the water temperature in the unit is too high and the unit shuts down.

 

The water tank leaks and the water level in the water tank drops, and the unit will not work normally (in order to prevent the water pipe from freezing when the generator is used in winter, it is recommended to install a water heater in the cooling system).

 

As long as the backup power supply is prepared, not only will it not waste resources in normal times, but it can start itself at the critical moment of a power outage, and the power can be restarted within ten seconds, which can completely avoid the loss caused by the power outage.

 

The above is the question of how often the diesel generator set of the standby power supply is maintained and how to maintain it. If there is anything you don’t know, please contact Dingbo Power by email dingbo@dieselgeneratortech.com.
