introduction
According to data from Huaquan Laboratory, generators sealed according to standard procedures have a successful start-up rate of up to 98.7% after 3 years. This article reveals 7 core technologies from pre-processing before storage to wake-up operations, helping you cope with engineering downtime, seasonal shutdowns, and other scenarios, ensuring that equipment is always in a state of readiness.
1、 Pre treatment of "three precautions" before sealing
1. Deep cleaning and anti-corrosion
Operation points:
Use an ultrasonic cleaning machine to treat the fuel system and remove carbon deposits and moisture;
Spray nano scale rust inhibitor on exposed metal parts to form a 3 μ m protective film;
Replace CF-4 grade rust proof engine oil and add 2% humidity absorbent to the oil.
2. Anti deterioration of fuel system
Key steps:
Keep the fuel tank at 80% full (to prevent condensation from accumulating);
Add diesel stabilizer (in a ratio of 1:1000) to inhibit oxidation reaction;
Install a one-way valve at the end of the fuel pipeline to prevent air backflow.
3. Battery maintenance to prevent power loss
Technical solution:
After disconnecting the negative electrode, use an intelligent pulse charger to recharge every month;
Apply conductive grease on the surface of the battery to prevent oxidation of the pole;
When the ambient temperature is below 5 ℃, a constant temperature insulation sleeve needs to be installed.
2、 The principle of "three controls" for storage environment
1. Temperature and humidity control
Use an electronic dehumidifier to maintain a relative humidity of ≤ 45% and a temperature controlled within the range of 15-25 ℃.
2. Dustproof and rodent proof design
Install stainless steel rat proof mesh (aperture ≤ 5mm) at the intake and exhaust ports;
The whole machine is covered with an anti-static dust cover (visually inspect the integrity weekly).
3. Ventilation management
Start the circulating fan for 15 minutes every month to maintain air circulation;
Avoid direct sunlight and prioritize choosing underground warehouses or rooms facing north.
3、 Four step wake-up operation
1. Pre start check
Detect three core parameters: oil level, coolant freezing point, and battery voltage;
Manually turn the wheel 2-3 times and confirm that there is no jamming phenomenon.
2. System activation
After connecting the power, start the preheating mode (Huaquan patented preheating algorithm, increasing the heating rate by 40%);
The fuel system performs three no-load cycles (each lasting 30 seconds).
3. Load testing
Load in steps of 25%/50%/75% in the first hour, monitor the stability of smoke exhaust color/frequency;
Use a vibration analyzer to detect engine harmonics and ensure no abnormal fluctuations.
4. Parameter reset
Reset ECU parameters through the control panel to restore the original factory calibration state.
Case Study Evidence
After the Huaquan generator set of a certain African mining project was sealed for 28 months, local engineers followed this process and the first start-up took only 8 seconds. The power attenuation during full load operation was less than 3%, and the increase in fuel consumption was controlled within 5%.
conclusion
Scientific sealing can extend the lifespan of Huaquan generators to over 12000 hours. Suggest establishing electronic health records for equipment, recording changes in key node parameters, and entrusting Huaquan certified engineers to conduct annual in-depth maintenance.
