Strictly speaking, the gas boiler needs to do an overall inspection and related repair and maintenance work within three months of operation to ensure the safe operation of the boiler to the maximum extent and avoid safety accidents. The content of maintenance mainly refers to the local and preventive maintenance of the boiler without stopping the furnace during operation. The boiler operation personnel are the main ones, and the maintenance personnel are supplemented. The specific maintenance parts are as follows.
1. Pressure gauge: Check and eliminate the leakage of the cock and the condensate pipe joint; turn the three-way cock to check whether the pressure gauge pointer returns to zero; check whether the condensate pipe is unblocked.
2. Water level gauge: Check the water level gauge cock; eliminate leakage and air leakage; repair and replace damaged parts.
3. Safety valve: Check the safety valve for leaks; check whether the seal is damaged or not, and whether the exhaust pipe is unblocked.
4. Pipelines and valve parts: cleaning and touch up the exterior part of the paint; maintenance of pipelines and valve parts leaking and leaking phenomenon.
5. Auxiliary equipment: Check water supply, circulating water pump and water treatment equipment. Clean the pump inlet filter and oil and gas filter.
6. Thermometer: check the thermometer, to be clearly visible.
7. Automatic control device: check the circuit, controller, regulating valve, operating system and electrical instrumentation, whether the line is loose; check the ignition program and the reliability of the interlocking alarm protection device.
The above is the FANGKUAI Boiler for you to organize, the gas boiler must be regularly maintained during the operation of the gas boiler, hope to help your boiler equipment, away from dangerous accidents.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance.
