How to maintain the battery of diesel generator set?

The maintenance cycle of the battery of the diesel generator set is carried out once every 50 hours without operation. (Yanan diesel generator solution: 4000-080-999).

1. Use a electroscope to check whether the battery is fully charged, otherwise it should be charged.

2. Check whether the battery liquid level is there.

About 15mm on the plate, if it is not enough, add electrolyte to the above position.

3. Check whether the battery binding post is corroded or has ignition marks, otherwise it should be repaired or replaced, and coated with butter.

4. The charging and discharging of the battery should be recorded.

The battery is the most important starting component of the diesel generator set, and its function is to implement the electric start of the diesel engine and the control of the fuel system of the unit, and to control the real-time start-operation and stop of the automatic unit. If it can not supply power normally, the diesel generator set will not be able to generate electricity, and the backup emergency power supply system will lose its guarantee role, which will cause unnecessary losses and serious consequences. In order to make the operation of the diesel generator set stable, manufacturers should take good care of it and do a good job in the maintenance of the battery (battery).

Maintenance and maintenance skills of diesel generator set battery: (1) When charging the battery for the first time, it should be noted that the continuous charging time should not exceed 4 hours, and the charging time is too long to cause damage to the service life of the battery; The battery is stored for more than 3 months, and the charging time can be 8 hours; Ambient temperature over 30 (86°F) or relative humidity above 80% continuously, charging time 8 hours, if the battery has been stored for more than 1 year, charging time can be 12 hours, at the end of the charging line, check whether the electrolyte level is sufficient, if necessary, add the correct specific gravity (1: standard electrolyte.

2) Scrub the outside of the battery with a damp cloth, and wipe the dust, oil, white powder and other dirt that is easy to cause leakage on the panel and pile head (i.e., the positive and negative poles). In this way, the battery will be scrubbed frequently, and the pile head of the battery will not accumulate white etching powder, and its service life will be relatively long. (3) Check whether the battery is charged normally; If you have a triple power meter, after starting the engine, measure the voltage at the two poles of the battery, which must exceed 13V to be considered normal; If you find that the charging voltage is too low, you need to ask a professional to overhaul the charging system.

If there is no three-power meter, you can use the visual method: after the engine starts, open the battery and water cover to see if there are bubbles in each small compartment; The normal condition is that bubbles are constantly coming out of the water, and the more oil you add, the more they will rise; If you notice that there is no bubbling, it is likely that there is something wrong with the charging system. (4) Open the battery and water cap to see if the water level is in the normal position.

Generally, there will be upper and lower limit markings on the side of the battery for your reference. If you find that the water level is lower than the lower mark, you must add distilled water, if you can't get distilled water at once, you can use filtered tap water to deal with emergencies. Don't add too much water, the standard is to add it to the middle of the upper and lower reticles.

Precautions: (1) When the battery is rehydrated, it is not advisable to add too much distilled water or purified water; When the battery is discharged, the electrolyte inside the diesel engine will gush out from the overflow hole of the filling port, causing corrosion and damage to the surrounding objects and environment. (2) Avoid starting the unit at low temperature, the battery capacity will not be able to output normally in the low temperature environment, and long-term discharge may cause battery failure (cracking or **).

3) When maintaining the battery, you should wear an acid-proof apron and a mask or protective glasses, and once the electrolyte accidentally splashes on ** or clothing, you should immediately rinse with plenty of water. (4) Hydrogen will be produced during the inspection of the battery, so do not smoke during the inspection to avoid the danger of ****.

1: Requires frequent wiping. 2: Open the water cap of the battery to see if the water level is normal. 3: Check whether the battery charging is normal at regular intervals.

1. The diesel generator battery stored for a long time must be properly charged before use to ensure the normal capacity of the diesel generator battery.

2. Normal operation and charging will lead to the evaporation of some water in the diesel generator battery, which requires frequent replenishment of the diesel generator plex elimination battery, before replenishment, the dirt around the filling port should be cleaned to prevent it from falling into the diesel generator battery grid, and then the filling port should be opened, add an appropriate amount of distilled water or purified water, do not overfill, take the diesel generator battery plate scale as the standard, otherwise the diesel generator battery discharge When charging, the internal electrolyte will gush out from the overflow hole of the filling port. Cause corrosion and damage to surrounding objects and the environment. The actual capacity of the diesel generator battery can be measured by means of a hydrometer.

3. Avoid starting the diesel generator battery at low temperature, the capacity of the diesel generator battery will not be able to output normally in the low temperature environment, and long-term discharge may cause the failure of the diesel generator battery.

4. The diesel generator battery of the standby generator set should be regularly maintained and charged, and can be equipped with a floating charger.

5. Use a damp cloth to scrub the outside of the diesel generator battery, and wipe the dust, oil, white powder and other leakage dirt on the panel and pile head (that is, the positive and negative electrodes). In this way, the diesel generator battery is often scrubbed, and the pile head will not accumulate white acid etching powder, and its service life will be relatively long.

6. Open the diesel generator battery and water cover to see if the water level is in the normal position. Generally, there will be upper and lower limit markings on the side of the diesel generator battery for reference. If you find that the water level is lower than the lower mark, you must add distilled water, if you can't get distilled water at once, you can use filtered tap water to deal with emergencies.

Don't add too much water, the standard is to add it to the middle of the upper and lower reticles.

7. Check whether the battery is charged properly. If there is a three-power meter, measure the voltage of the two poles of the diesel generator battery after starting the engine, and it must exceed 13V or more to be considered normal. If you find that the charging voltage is too low, you need to ask a professional to overhaul the charging system.

If there is no three-power meter, you can use the visual method: after the engine starts, open the diesel generator battery and banquet water cover to see if there are bubbles in each compartment. The normal condition is that bubbles are constantly coming out of the water, and the more oil you add, the more they will rise; If you find that there is no bubbling, it is likely that there is something wrong with the charging system.

It is important to note that hydrogen gas is produced during this test, so do not smoke during the test to avoid danger.

For the sake of safety, when maintaining the diesel generator set and starting the battery, you should wear an acid-proof apron and wear a ridge and a cover or protective glasses.

The battery is dry when it is just delivered to the user, and the maintenance of the diesel generator set should pay attention to the correct specific gravity (1: electrolyte) that has been evenly mixed before use. Unscrew the top cover of the battery compartment and slowly inject the electrolyte until it is between the two scale marks on the upper part of the metal sheet and as close to the upper scale as possible.

After adding it, please do not use it immediately, and let the battery stop for about 15 minutes.

When maintaining the diesel generator set to start the battery, it should be noted that when charging the battery for the first time, it should be noted that the continuous charging time should not exceed 4 hours, and the charging time is too long to damage the service life of the battery. The charging time is allowed to be appropriately extended when one of the following occurs: the battery is stored for more than 3 months, the charging time can be 8 hours, the ambient temperature is more than 30 (86°F) or the relative humidity is consistently higher than 80%, the charging time is 8 hours, if the battery is stored for more than 1 year, the charging time can be 12 hours, and at the end of the charge, the electrolyte level should be checked to see if it is sufficient, and the correct specific gravity can be added if necessary (1:

standard electrolyte.

The maintenance and maintenance of the generator has always been a big problem, many businesses can not do the maintenance and maintenance of the generator frequently, whether it is before, during or after use, but the generator is required to be maintained and maintained frequently, otherwise it is easy to cause a lot of problems, today I will focus on the daily maintenance and maintenance of diesel generator sets. (Yananda Yanan Group: R&D and production of diesel generator sets and fuel cells).

2 Maintenance precautions.

The staff responsible for the protection and maintenance of the generator must carefully read the manufacturer's "Diesel Generator Insurance Operation and Maintenance Manual" (manual), and carry out maintenance and maintenance work according to the relevant skill requirements.

If the generator is parked for too long or is damp, the insulation resistance between the windings and to the ground should be measured, and the insulation value should not be lower. Be careful to remove the negative wiring of the start-up battery before measuring.

Depending on the site situation, clean the dust and grease on the windings of the generator from time to time.

The generator should not be exposed to moisture, and the inside of the generator should avoid metal chips, water vapor or other harmful gases. When the generator is running, it is necessary to ensure good ventilation, and there should not be any covering outside the generator to avoid affecting ventilation and heat dissipation.

The generator battery should be kept away from the heat source, and the ventilation should be maintained during charging and application.

Frequent maintenance of the generator is a good way to extend the service life of the generator and improve the efficiency of the generator, there are many maintenance methods for the generator, there are many maintenance methods, and it is not necessary to do it all, it is good to do one or two points, but it is absolutely impossible not to maintain the generator, which is a very harmful thing for the generator.
