Storage Method for Long Term Shutdown of Shangchai Generator 6DTAA8.9-G21

Diesel generator set is a widely used power generation equipment due to its stable and reliable performance, flexible maneuverability, low investment, easy start-up, low fuel consumption, low emissions and other advantages. It is widely used as an emergency or backup power source in communication, mining, construction, farmland irrigation, field construction and other departments. When not in use, some units may be shut down for a long time. Dingbo Power reminds you that when the diesel generator set is shut down for more than 3 months, it should be sealed. This article takes the 6DTAA8.9-G21 diesel generator set from Dingbo Electric as an example to provide a detailed introduction to the storage methods for long-term shutdown of diesel generator sets.

Before sealing the 6DTAA8.9-G21 diesel generator

1. After the last use of the diesel generator, drain the lubricating oil of the unit in a hot state, including the oil in the oil filter, and hang a label on the diesel engine, stating that the diesel engine has no oil and should not be used. Due to the anti rust function of the coolant, it does not need to be discharged. Add qualified sealed oil of the specified capacity into the crankcase, start the diesel engine to idle, run for 1-1.5 minutes before stopping, and then release the sealed oil from the oil pan. The sealed oil inside the 6DTAA8.9-G21 engine of Shangchai Generator is dehydrated CF grade 15W/40 lubricating oil.

2. Cleaning, rust prevention, and other sealing requirements for the outer surface of diesel engines

1) Clean the surface of the diesel engine, check for visible dirt, oil stains, rust, water stains, etc., and then dry it with compressed air; Use a brush to evenly apply rust proof oil to all machined surfaces of diesel engine metal surfaces (i.e. unpainted machined surfaces); Note that the surfaces of rubber parts, plastic parts, and fiber fabric parts must not be coated with rust proof oil or come into contact with rust proof oil.

2) Disconnect the battery connection wire, clean the terminals, apply a thin layer of grease, and charge the battery.

3) Loosen the transmission tape.

4) Seal or wrap all exposed air ducts, water pipes, or oil pipe openings with moisture-proof paper, vapor phase rust proof paper, or polyethylene plastic film tape. The entire air filter should also be sealed or wrapped with moisture-proof paper.

5) Cover the diesel engine with a plastic cover or similar material and place it in a well ventilated dry room.

During the storage period of Shangchai Generator 6DTAA8.9-G21

During the storage period of the diesel generator set, attention should also be paid to charging the battery every month and checking the battery level. If necessary, the battery should be added before charging.

Use the 6DTAA8.9-G21 diesel generator after unpacking

When it is necessary to restart the diesel generator 6DTAA8.9-G21, the old unit cover should be removed, and the sealing and wrapping materials of each pipe should be removed. When starting, the fuel injection pump should be removed and adjusted, then reinstalled, and the fuel system pump oil should be drained. Connect the pipeline and battery connection, tighten the drive belt, add clean engine oil that meets the regulations to the diesel engine and oil filter, and add an appropriate amount of engine oil to the oil inlet of the turbocharger. Check the oil level and coolant level. Use a turning tool to rotate the crankshaft 3-5 revolutions first, and then use the correct method to start the unit.

Attention: If the storage period exceeds 2 years, the coolant must be replaced and the cooling system must be cleaned before use.

The use and short-term/long-term storage of diesel generator sets require careful maintenance by users to ensure that the performance of the set is not affected, reduce unnecessary faults, and extend the service life of the set.
