Checks before commissioning
1. Check whether the diesel oil is in place, whether the fuel pipeline is clean and smooth, and whether the valve is opened.
2. Whether there is any pipeline leakage, and whether the pipeline installation is reasonable.
3. Whether the oil inlet and return pipelines are installed correctly, and the oil return pipeline is not allowed to install valves
Internal inspection of fuel engine
1. Whether the oil nozzle of the burner is installed and the ignition electrode should be adjusted well.
2. The direction of motor rotation should be correct.
3. The external circuit connection should meet the requirements.
4. Carry out cold state simulation of the burner according to the circuit conditions, and observe that all parts of the equipment in operation should be normal and the flame detection and protection part should be normal.
Commissioning of the burner
1. Check whether the external diesel oil is in place, whether the pipeline is unobstructed, and whether the external power supply is in place.
2. Adjust the load of the burner to a small load, adjust the ignition position to a small load accordingly, turn off the large load to ignite and observe the flame situation, and adjust the servo motor or damper accordingly according to the flame situation.
3. When adjusting the high fire output of the burner, it is necessary to gradually adjust from a relatively small load to a large load according to the load of the heat-consuming equipment, and adjust the servo motor or damper accordingly according to the situation.
4. Observe whether the flame has partial fire, insufficient flame combustion, vibration and other phenomena.
5. After the adjustment, perform multiple ignitions to see if the ignition is good.
site requirements
1. Personnel irrelevant to the commissioning operation are required to leave the operation site.
2. Any other operation (such as electric welding, gas cutting, etc.) is prohibited.
3. In order to ensure the personal safety of the commissioning personnel, when the burner is ignited, it should be 1 meter away from the side of the burner. When the flame is burning stably, the flame can be observed at the observation mirror, and the next step of output adjustment and other adjustments should be made. .
Matters needing attention in fuel engine commissioning and maintenance
1. When the secondary ignition procedure of the oil burner fails continuously, stop the machine and check whether the fuel supply system of the burner is normal and whether the circuit connection is correct. The burner can only be restarted after the fault is resolved.
2. Smoking, welding, cutting and other illegal operations on site are strictly prohibited.
3. In the commissioning work, it must be serious, safe and efficient.
4. It is forbidden to use non-explosion-proof electrical and electric tools on site.
5. Explain the precautions for safe operation to customers in detail.
6. It is required to check whether the oil circuit is open before starting the machine.
7. It is recommended not to debug the fuel engine at night.
8. At the end of the commissioning, it is necessary to organize operators to train them in the direction of operation, and establish an operation process if necessary.
