How to maintain and repair the combustion engine? What are the issues to pay attention to when using a combustion engine?

一、 Debugging, maintenance, and maintenance precautions for combustion engines

1. Before debugging the combustion engine, check whether the gas is in place, whether the gas pipeline is clean and unobstructed, whether the valve is open, whether there is any pipeline leakage, whether the installation of the pipeline is reasonable, and exhaust the gas from the pipeline in front of the gas valve to ensure that there is no mixed air in the pipeline.

2. Internal inspection of the combustion engine includes: whether the combustion head of the combustion engine is installed or adjusted properly; Is the direction of motor rotation correct; Whether the external circuit connection meets the requirements; Conduct cold simulation of the combustion engine based on the circuit conditions, observe whether all components of the equipment in operation are normal, and whether the flame detection and protection parts are normal.

3. The debugging of the combustion engine includes checking whether the gas is in place, whether the gas pipeline is clean and unobstructed, and whether the external power supply is controlled in place; Adjust the load of the combustion engine to low load, and the ignition position should be adjusted to low load. Turn off the high load for ignition and observe the condition of the flame. Adjust the servo motor, damper, and gas valve group accordingly according to the condition of the flame; Observe if there is any deviation of flame, insufficient combustion of flame 9, vibration, and other phenomena; After adjustment, multiple ignition should be carried out to observe if the ignition is good.

二、 Precautions for using a combustion engine!

1. The light diesel used in the combustion engine must be clean, and attention should be paid to regularly cleaning the fuel tank and oil filter.

2. Under normal circumstances, the oil nozzle of the combustion engine needs to be replaced once a year, and the elastic coupling and rubber parts on the coupling need to be replaced once a year and a half.

3. Foreign objects are prohibited from entering the air duct inside the combustion engine.

4. The site where the combustion engine is used should be kept away from flammable and explosive materials and equipped with fire extinguishing equipment.

5. If the ignition program of the combustion engine fails twice in a row, it is necessary to shut down and check whether the gas supply system of the burner is normal and the circuit connection is correct. Only after the fault is resolved can the combustion engine be restarted.

6. The gas supply pipeline of the combustion engine cannot be knocked or rubbed with objects such as wrenches or metal rods to avoid static electricity and sparks, which can cause gas explosions.
