When using air compressors in daily life, many customers will ask whether there are any precautions for starting up, how to maintain, etc. Let's briefly talk about what to pay attention to when starting and maintaining permanent magnet variable frequency air compressors.
First of all, let's talk about the following points when starting up permanent magnet variable frequency air compressors:
1. The indoor temperature of our air compressor room must be kept above 5℃, so that the permanent magnet variable frequency air compressor can be started;
2. Close the sliding door of the air compressor unit exhaust vent that is not turned on, and close the hot exhaust vent to the room to ensure the indoor temperature;
3. Before starting the permanent magnet variable frequency air compressor, confirm whether the dryer outlet valve is in the open state;
4. Before starting the permanent magnet variable frequency air compressor, turn on the dryer 5 minutes in advance;
5. Before starting, check whether the air compressor oil level is above the normal liquid level scale of 15 (note that the unit During loading operation, the cooling oil level scale is normal between 3-17; if it is too low, it is necessary to stop the machine immediately and add it to the specified value range; because each manufacturer and machine model is different, it is set according to the manufacturer's requirements), and there is no obvious oil leakage in the unit;
6. If the permanent magnet variable frequency air compressor unit in operation is found to have oil leakage and abnormal noise, please stop the machine in time and restart the machine after confirming that the fault has been eliminated;
7. If the machine has not been started for a long time, before restarting it, the permanent magnet variable frequency air compressor should be checked according to the manufacturer's requirements before starting it again.
Let's talk about the daily maintenance content and precautions of variable frequency air compressor
1. We need to check the air filter element and coolant level of the permanent magnet variable frequency air compressor;
2. Check whether the hose and all pipe joints are leaking;
3. Check whether the consumable parts have reached the replacement cycle. If it is necessary to stop the machine, they must be replaced;
4. Check the exhaust temperature of the main engine (the temperature value refers to the temperature provided by the air compressor manufacturer). If it is too high, it is necessary to clean the oil cooler or provide technical support according to the air compressor manufacturer;
5. Pay attention to check the condensate discharge. If condensate is found in the oil and gas barrel, it is necessary to stop the machine for discharge;
6. Pay attention to check whether there is abnormal sound in the permanent magnet variable frequency air compressor.
