Gas generator use natural gas, liquefied petroleum gas, and other fuels, which have the advantages of cleanliness, efficiency, and low operating costs. However, safety regulations must be strictly followed during use. The following are key precautions and operational suggestions:
1、 Preparation before installation of Gas Generator
Site requirements
Gas Generator with good ventilation: The installation area needs to have a forced ventilation system to prevent gas leakage and accumulation.
Fire and explosion prevention: Keep away from flammable materials and equip with gas leak alarms and fire extinguishers.
Stable foundation: The unit should be installed on a horizontal concrete foundation to avoid vibration displacement during operation.
Gas Generator Gas Pipeline Connection
Professional construction: Pipeline welding and pressure testing must be carried out by qualified units.
Material compliance: Use seamless steel pipes or specialized gas hoses, and regularly check the sealing at the interface.
Electrical system inspection
Reliable grounding: grounding resistance ≤ 4 Ω, preventing accidents caused by lightning strikes or leakage.
Cable specifications: Select matching cables based on the power of the unit.
2、 Gas Generator Startup and Operation
Pre startup inspection
Gas supply: Confirm that the valve is open and the pressure is stable within the rated range.
Lubricating oil level: The oil level should be between the upper and lower limits of the scale, and the manufacturer's recommended brand of engine oil should be used.
Cooling system: Check the coolant level and concentration.
Gas Generator Startup Operation
Pre lubrication: Manual starting models require 2-3 turns of turning, while electric starting models require 3-5 minutes of preheating.
Ignition sequence: Follow the process of "gas valve slightly open → ignition → gradually increase gas volume" to avoid detonation.
Operation Monitoring
Gas Generator parameter recording: Record exhaust temperature, oil pressure, and frequency every hour.
Exception handling:
Exhaust emitting black smoke: Adjust the air-fuel ratio or clean the fuel injector.
Excessive vibration: Check the levelness of the unit and the tightening of the foundation bolts.
3、 Gas Generator Shutdown and Maintenance
Shutdown steps
Load unloading: Cut off the load first and run it without load for 3-5 minutes before stopping to prevent high temperature damage to the turbocharger.
Valve closure: Immediately close the gas main valve after shutdown to avoid gas leakage.
4、 Gas Generator Safety Operation Specification
Personnel protection
Operators must hold a certificate and wear anti-static work clothes, safety helmets, and protective gloves. It is prohibited to conduct maintenance or adjustment during the operation of the unit.
Emergency Management
Gas leakage:
Immediately close the gas main valve and start the exhaust system. Do not touch electrical switches and use explosion-proof intercoms to sound the alarm.
Fire:
Use CO ₂ or dry powder fire extinguishers and do not use water to extinguish fires. When the fire gets out of control, evacuate the scene and activate the fire linkage system.
environmental safety
Explosion proof lighting equipment should be equipped for night operations to avoid static electricity causing explosions. During thunderstorm weather, it is necessary to shut down and disconnect the mains power connection to prevent lightning damage to equipment.
The safe operation of a gas generator needs to run through the entire process of installation, operation, and maintenance. Operators must strictly follow the specifications, conduct regular inspections, and respond quickly to abnormalities. Through scientific management and maintenance, the efficient and stable power supply of the unit can be ensured, reducing the risk of accidents.
