Common Troubleshooting of Permanent Magnet Variable Frequency Air Compressor in Summer

In summer, when the permanent magnet variable frequency air compressor is used in a continuous high temperature environment, it will accelerate the loss of equipment, and even accelerate the oxidation of the oil in the oil barrel, resulting in cementing. The most common failure is high temperature shutdown. Therefore, it is particularly important to monitor the exhaust temperature of the permanent magnet variable frequency air compressor in time and accurately eliminate the fault caused by the high temperature of the air compressor.

1. Control the ambient temperature of the machine room

the operating environment of the permanent magnet variable frequency air compressor shall be lower than 38 ℃. Improve the ventilation system of the air compressor room, increase the exhaust fan of the permanent magnet variable frequency air compressor room to discharge hot air, thereby reducing the temperature.

If the temperature around the machine is relatively high, it will cause the suction temperature of the machine to be too high, so that the oil temperature and exhaust temperature will rise accordingly, which should be paid attention to in summer.

2. Air-cooled air compressor, clean up radiator dust

the radiator is kept smooth and clean, and the dust is large. The radiator should always clean up the dust, and ensure that the permanent magnet variable frequency air compressor sucks in the smooth first line of air and dust radiator, which will also cause the permanent magnet variable frequency air compressor oil The filter is blocked, causing the lubricating oil path to be blocked, and the amount of oil entering the host is small, resulting in high temperature and cooling.

3, water-cooled air compressor can reduce the inlet water temperature

check whether the cooling water temperature and water pressure are normal. The inlet water temperature of the air compressor is generally not more than 35 ℃, and the water pressure is between 0.3 and 0.5Mpa. At the same time, the scale of the cooler is removed to ensure the heat exchange efficiency. If the water temperature does not meet the requirements, a cooling tower can be installed.

4, Regular maintenance of permanent magnet variable frequency air compressor filter

permanent magnet frequency conversion air compressor filters mainly include: air filter, oil filter, oil and gas separator. The clogging of the air filter will cause the air compressor to be overloaded and overloaded for a long time, causing the temperature to be too high. Clogging of the oil core will cause high internal pressure and high temperature. The clogging of the oil filter will cause the flow to decrease and generate high temperature.

The dust in the air sucked by the permanent magnet variable frequency air compressor is blocked by the air filter. In order to avoid premature wear of the screw compressor and clogging of the fine filter element in the oil and gas separator, it is usually necessary to replace the new filter element after a period of operation. At the same time, check whether the oil filter and filter element of the oil and gas separator need to be replaced.

5. Use genuine air compressor oil during maintenance

insufficient oil supply for the permanent magnet variable frequency air compressor or insufficient oil supply inside the machine will also cause the air compressor temperature to be too high. When the weather is hot in summer, the position of the oil level mirror oil in the oil and gas barrel should be checked. If it is found that the oil level is lower than the oil level mark, the oil level should be stopped after refueling to prevent high temperature. In addition, be sure to use genuine air compressor oil to ensure the operation of the air compressor.

In summer, in order to ensure the smooth operation and smooth production of your permanent magnet variable frequency air compressor, please regularly maintain the permanent magnet variable frequency air compressor equipment.
