Precautions for Storing Silent Diesel Generator Sets
IV. General Preparations Before Storing Silent Diesel Generator Sets
1. Clean the Silent Diesel Generator Set:
Clean the exterior of the silent diesel generator set, removing dust, oil, and moisture, especially around the radiator fins and air filters. Inspect and clean the chassis to prevent residual oil and water corrosion.
2. Choose a Suitable Location:
Indoor Storage: Preferably a dry, well-ventilated, and dust-free warehouse or engine room. The ambient temperature should not fluctuate drastically.
Outdoor Storage: If outdoor storage is necessary, a rain and sun shelter should be built to ensure the silent diesel generator set is completely protected from rain, sun, and dust. The ground should be solid, level, and higher than the surrounding area to prevent water accumulation.
Safe Environment: Keep away from flammable and explosive materials and avoid environments with corrosive gases (such as near chemical plants).
3. Power Off and Protection:
Turn the main switch on the control panel to the "OFF" position.
If possible, disconnect the starter battery (disconnect the negative terminal first, then the positive).
Cover the silent diesel generator set with the factory-supplied dust cover or a breathable cloth cover to prevent dust ingress. Do not use a completely non-breathable plastic cover directly, as this may cause condensation inside.
V. Short-Term Storage Precautions (< 1 month)
The focus of short-term storage is to keep the silent diesel generator set in a ready-to-start condition at all times.
1. Fuel System:
Ensure that the diesel tank of the silent diesel generator set has a sufficient amount of clean diesel and is filled to the maximum level to reduce condensation on the inner walls of the tank.
No special fuel stabilizer is needed, but the diesel should be of good quality.
2. Battery:
Keep the battery of the silent diesel generator set fully charged. It is recommended to check the electrolyte level and voltage every 2-3 weeks and recharge if necessary.
Alternatively, use a smart float charger (maintenance charger) to keep it connected constantly to maintain optimal charge.
3. Moisture Protection:
In humid environments, desiccant bags can be placed inside the silent diesel generator.
4. Regular Startup and Operation:
The silent diesel generator set should be started once every 2-3 weeks.
After starting, let the silent diesel generator set run for 15-20 minutes under no load or light load (not exceeding 30% of rated power).
Purpose: To lubricate the engine internals, remove moisture, charge the battery, and prevent the fuel system from gelling.
VI. Precautions for Long-Term Storage of silent diesel generator set (> 1 Month)
Long-term storage of silent diesel generator set requires comprehensive "sealing" treatment, focusing on draining, protection, and isolation.
1. Engine:
- Change the oil and filter of the silent diesel generator set: : Stop the engine immediately after it reaches operating temperature and drain the old oil. Replace with new oil and an oil filter. New oil provides better anti-rust protection.
- Internal engine rust protection:
- Crankcase: Inject about 15-20ml of special rust-preventive oil or engine maintenance oil into each cylinder through the injector hole.
- Manual rotation: Slowly turn the crankshaft 2-3 times to evenly coat the cylinder walls and piston rings with rust-preventive oil.
- Finally, place the pistons at top compression, keeping intake and exhaust valves closed to prevent valve springs from being constantly compressed and to isolate from air.
2. Fuel System (most critical step):
- Option 1 (recommended): Complete drainage. Run the silent diesel generator set until it stops automatically due to fuel exhaustion. Drain the residual fuel from the fuel filters, fuel-water separators, and entire fuel lines. This method prevents fuel deterioration and gelling during long-term storage, which could clog injectors.
- Option 2: If retaining fuel is necessary:
- Fill the fuel tank to a high level to reduce air space.
- Add a fuel stabilizer and circulate it thoroughly to slow down diesel oxidation and gelling.
- Remove air from the fuel lines and seal all openings tightly.
- Regardless of the method, change the fuel filter before storage.
3. Cooling System:
- Check the silent diesel generator set coolant level and condition. For long-term storage, it is recommended to drain the coolant (especially important in cold regions to prevent freezing), or replace it with long-life antifreeze and rust-inhibiting coolant.
4. Battery:
- Remove the silent diesel generator set battery from the generator set.
- Clean the terminals and apply petroleum jelly or grease to prevent oxidation.
- Store in a cool, dry place and recharge periodically (every 1-2 months), or use a smart maintenance charger.
5. Electrical and Control System:
- Lightly spray exposed metal connectors and terminals with anti-rust spray.
- Disconnect all unnecessary electrical connections.
6. Silent Enclosure:
- Check that the silent diesel generator set’s muffler, air inlet, and exhaust covers are intact to ensure weatherproofing.
- Inspect the enclosure seals to prevent rodents and other small animals from nesting or chewing wires. Metal rodent screens can be installed at ventilation openings.
VII. Q&A on Knowledge About Silent Diesel Generator Sets
1. How to choose the appropriate power for a silent diesel generator set?
Calculate the total rated power of all loads and consider the starting surge current of motor-type equipment (usually 3-7 times the rated power). The commonly used power of a silent diesel generator set should be at least 20%-30% higher than the stable total load.
2. What are the key requirements for installing a silent diesel generator set?
- Ventilation first: Leave at least 1.5 meters of space in front of air inlets and outlets; blocking is strictly prohibited.
- Stable foundation: Concrete foundation with vibration-damping pads to reduce vibration transmission.
- Exhaust safety: Extend exhaust pipes outdoors and tilt them downward to prevent rainwater backflow.
- Cable standards: Connect through waterproof junction boxes, and ensure cable cross-section matches the power.
3. What are the key points of daily maintenance for a silent diesel generator set?
- Check engine oil, fuel, and coolant levels daily.
- Clean the surface of the silent diesel generator set weekly and check for any leaks.
- Run idle for 15-20 minutes monthly (if not used regularly).
