IV. Precautions for Plant Generator Maintenance
Maintaining plant generator is a crucial step to ensure their reliable operation during critical moments. Therefore, maintenance is very important. The following is a complete list of precautions for plant generator maintenance, divided into daily/weekly, monthly, semi-annual/annual, and special precautions.
1. Daily/Weekly Maintenance (Performed by Operators)
These are basic checks to ensure that the plant generator is on standby.
Appearance Check: Inspect the surface for any signs of oil or water leaks. Check whether there are any debris, tools, etc., in the engine compartment and keep it clean.
Fuel System Check: Check the diesel fuel tank level to ensure it is sufficient. Observe the fuel lines for any leaks.
Lubrication System Check: When the plant generator is stationary, check the engine oil level using the dipstick.
Battery Check: Observe the battery terminals for corrosion or looseness. Check the battery charge (if there is a gauge).
Control Panel Check: Check the control panel for any warning lights.
Plant Generator Cooling System Check: Ensure the radiator coolant level is within the normal range, and add antifreeze of the same brand and model if necessary. Check the cooling water pipes for aging, cracks, or leaks.
2. Monthly Maintenance and Testing (to be performed by professional electricians or maintenance personnel)
No-load/Load Test: Under normal mains power, manually start the plant generator and run it for at least 30 minutes.
Purpose: To lubricate the engine internals, remove carbon deposits, burn off moisture, and verify startup and operational performance.
Load Test: Simulate actual load as much as possible, allowing the plant generator to run with at least 30%-50% of its rated load for a period of time. This allows for a true test of its load-bearing capacity.
Checks During Operation:
- Observe Exhaust: The exhaust should be colorless or light gray. Black smoke (incomplete combustion), blue smoke (burning oil), or white smoke (coolant leak) are abnormal.
- Listen for Sounds: The plant generator should operate smoothly without unusual knocking or friction noises.
- Monitor Gauges: Check that oil pressure, coolant temperature, voltage, and frequency are within normal ranges.
- Check for Leaks: During operation and after shutdown, carefully inspect for any oil, water, or air leaks.
3. Semi-annual/annual maintenance: This is in-depth maintenance to ensure long-term reliability.
Replace the plant generator oil and oil filter: This is an important maintenance task. Even if the operating hours have not been reached, the oil can deteriorate.
Replace the fuel filter: Prevent impurities from clogging the injectors and ensure combustion efficiency.
Check the starter motor and generator: Inspect for wear on carbon brushes, bearings, and other components.
Replace theplant generator coolant: Coolant can become ineffective, causing corrosion or lowering the boiling point.
Inspect and replace belts: Check the fan belt, alternator belt, etc., to prevent aging and breakage.
Clean the plant generator interior and radiator fins: Dust and grease can significantly affect heat dissipation.
Replace the air filter: Ensure smooth airflow to prevent decreased plant generator power and accelerated wear.
Check and tighten all screws and wiring terminals, including the plant generator base, exhaust pipe, and power output terminals.
Simulate a utility power outage test: Test whether the automatic transfer switch can correctly detect a power outage, automatically start the plant generator, and complete the switch.
4. Special Precautions and Practices
Fuel Management: Use high-quality, clean diesel. The fuel tank should be cleaned regularly to prevent water and sediment buildup.
Battery Maintenance: The battery is a common point of failure in plant generator. Ensure that the float charger is functioning properly and check the electrolyte specific gravity regularly (for non-maintenance-free batteries).
Keep It Clean: A clean and tidy plant generator room not only prolongs the equipment's lifespan but also makes it easier to spot issues during inspections.
Establish Maintenance Logs: Detailed records should be kept for every inspection, test, maintenance, and repair work, including the date, operating hours, tasks performed, and any parts replaced. This serves as a reference for troubleshooting and planning the next maintenance.
Professional Maintenance Contracts: For critical power sources, it is strongly recommended to sign a maintenance contract with the original generator manufacturer or an authorized professional service provider.
Plant Generator Safety: All maintenance operations must be carried out with the generator shut down and with a “Do Not Energize” warning sign posted.
V. Plant Generator Customization Process
In simple terms, the entire process of customizing a plant generator is: submit requirements, design and quote, production and testing, installation and acceptance, and after-sales support.
1. Requirement Communication – Clarify What You Need
The key is to understand: purpose (backup or primary use), total power (kilowatts, kW), installation environment (indoor or outdoor), and budget range.
2. Proposal and Quotation – Design the Plan
The manufacturer will provide a detailed technical proposal and price list based on your requirements. The proposal will specify engine brand, control system functions, etc. Both parties confirm and then sign the contract.
3. Production and Testing – Ensure Quality
The plant generator is manufactured according to the contract and undergoes strict factory testing (including no-load and load tests) to ensure performance standards are met. This is the core guarantee of quality.
4. Delivery and Commissioning – Complete Installation
The plant generator arrives on-site, where professional engineers install, wire, and perform on-site commissioning, simulating real power outages to ensure everything works perfectly.
5. Training and After-Sales – Ensure Long-Term Use
Train your operators and establish an after-sales service record to ensure long-term stable operation.
VI. Q&A on Plant Generator
1. How to choose a plant generator with the appropriate power?
Calculate the total load: List and sum up the rated power of all equipment that needs to be powered.
Consider the starting current: Motor-type equipment (such as air compressors) requires 3-7 times more instantaneous power at startup than during running.
Reference formula: Required generator power ≈ (Sum of all equipment's steady-state power + startup increment of the largest motor) × safety factor (usually 1.1-1.25). It is recommended to consult Huazhen professional engineers for the calculation.
2. Why do plant generator need to run regularly with no load or with load?
Lubricate the inside of the engine and prevent rust.
Burn off carbon deposits to maintain engine performance.
Charge the battery to ensure sufficient power.
3. What other factors are often overlooked when choosing a plant generator?
After-sales service and parts supply: Whether there is a wide service network and timely provision of spare parts.
Future expansion needs: Whether to leave room for power increase.
Local environmental regulations: Restrictions on noise and emissions.
4. What is a plant generator ATS system?
Automatic Transfer Switch (ATS), which can monitor utility power and automatically start the plant generator and switch power during a utility outage.
VII. Application Scenarios of Plant Generator
1. When the mains power is completely interrupted (faults, natural disasters)
Scenario: Large-scale power outages caused by grid faults or severe weather (such as typhoons, ice, and snow).
Function: Automatically start to supply power to key equipment and areas, preventing production interruptions. This is the core mission of plant generators.
2. During planned power outages by the grid
Scenario: Line maintenance, grid upgrades, etc., notified in advance by the power supply company.
