The farm environment is complex and ever-changing, with high humidity, dust, and corrosive substances (such as fertilizers and pesticides) posing a threat to the stable operation of generators. If there is a lack of effective protection, the generator is prone to moisture, short circuits, dust accumulation, overheating, and even metal component corrosion, leading to frequent failures. This article provides a comprehensive practical guide from environmental analysis, protective measures, daily maintenance to troubleshooting.
1、 The challenge of farm environment on generators
1. Moisture issue:
Generators stored outdoors or easily shielded are susceptible to rainwater and dew, which can cause moisture damage to the power lines and a decrease in insulation performance.
Consequences: Short circuit, damage to control module, and even fire.
2. Accumulation of sand and dust:
Farmland dust can easily clog the generator's heat dissipation port and air filter, reducing heat dissipation efficiency and increasing fuel consumption.
Consequence: Engine overheating and shutdown, power attenuation.
3. Chemical corrosion:
Corrosive substances such as fertilizers and pesticides adhere to the surface of the generator, accelerating the rusting of metal parts and damaging coatings.
Consequence: Perforation of the casing, rusting of screws, and shortening of equipment lifespan.
2、 Core protective measures
1. Moisture protection
Physical isolation: Build a rain shelter or use a waterproof generator cover to ensure that the ventilation opening faces downwards to prevent rainwater from flowing back.
Dehumidification equipment: Place desiccants or small dehumidifiers in the generator compartment and replace them regularly.
Sealing inspection: Check whether the rubber sealing rings at the door seams and cable entrances are aging and replace them in a timely manner.
2. Dust protection
Air filter: Choose a high-capacity, easy to clean filter, check every 50 hours, and shorten the inspection cycle after sandstorm weather.
Cooling system cleaning: Clean the gaps between the cooling fins with compressed air every week to prevent dust from forming an insulation layer.
Dust cover: Use a dedicated dust cover when shutting down to prevent dust from entering the engine interior.
3. Anti corrosion protection
Material selection: Stainless steel casing or galvanized metal parts are preferred to resist salt spray and chemical corrosion.
Coating protection: Regularly spray anti rust paint or anti-corrosion coating, with a focus on treating rust prone areas such as welding joints and screw holes.
Cleaning habits: Clean the surface of residual fertilizers and pesticides in a timely manner after use to avoid long-term adhesion and corrosion.
3、 Daily maintenance and inspection
1. Daily check:
Before starting, check if there are any foreign objects on the surface of the generator and if the ventilation openings are unobstructed.
Monitor for abnormal noise during operation and observe if the exhaust color is normal.
2. Weekly maintenance:
Clean the inside and outside of the generator, wipe the casing with a damp cloth (avoid direct flushing), and check if the cables are aging or cracked.
Test the grounding resistance to ensure compliance with safety standards (usually ≤ 4 Ω).
3. Seasonal maintenance:
Before the rainy season: check the sealing of the waterproof cover, clean the drainage channel, and test the residual current circuit breaker.
Long term storage: Empty the fuel tank, spray rust inhibitor, start once a month (15 minutes) to prevent battery depletion.
4、 Troubleshooting and Emergency Response
Moisture related malfunction: If there is difficulty starting or frequent tripping, priority should be given to checking whether the circuit joints are oxidized and drying the control module with a hair dryer.
Overheating shutdown: Clean the dust accumulation in the cooling system, check the coolant level, and ensure that the fan is running normally.
Corrosion perforation: If rust is found on the outer shell, immediately stop the machine, use epoxy resin for temporary repair, and contact professional maintenance.
conclusion
The protection of farm generators should be more effective than cure. Through scientific material selection, regular maintenance, and environmental management, the failure rate can be significantly reduced and the equipment life can be extended. It is recommended that farmers establish maintenance logs to record environmental data and maintenance details, providing data support for equipment upgrades or fault analysis.
