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.
The differences, advantages and disadvantages of rotor compressors and piston compressors are as follows: 1. differences: working principle: rotor compressors: through two meshing rotors, air is continuously squeezed and reduced in volume to achieve air compression. It is characterized by gas.
The power frequency and frequency conversion in the screw air compressor mainly refer to the control mode of its drive motor. There are significant differences between the two in many aspects. The following is a detailed summary of these differences: power frequency screw air compressor variable frequency screw air compressor
Question: What is the power of the oil-free air compressor? Answer: Usually the electric motor oil-free air compressor is the main body of a gas source device, which is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. And Shanghai Grank
The maintenance frequency of the oil injection air compressor is a university question! Just like we have to do a physical examination on a regular basis, the fuel injection air compressor also needs regular "care" to maintain its health and vitality. So, why do oil injection air compressors need to be so frequent
Whether the exhaust fan in the air compressor room needs to be explosion-proof depends mainly on the specific environment of the air compressor room and the risks that the exhaust fan may encounter. The following is a detailed analysis of this problem: air compressor room environment characteristics: air compressor room in the normal operation process, exhaust

From the application environment of oil-free air compressor, micro-oil air compressor is generally used in ordinary industrial production and oil-free air compressor is generally used in food, beverage, pharmaceutical and other occasions with high requirements for compressed air quality. From the quality of air compression, oil-free
The lithium industry has very strict requirements for compressed air equipment, which are mainly due to the high cleanliness, high precision and high stability requirements in the production process of lithium batteries. The following is a detailed summary of the requirements for compressed air equipment in the lithium battery industry: 1. air quality requirements
The difference between oil-free air compressor and oil-free air compressor is mainly reflected in the following aspects: Compressed air quality: oil-free air compressor: The compressed air produced does not contain oil and is suitable for applications that require high-purity gas, such as breathing, Spray, semiconductor manufacturing, etc.
Fermentation process is the use of microorganisms in aerobic or anaerobic conditions of life activities or direct metabolites or secondary metabolites of the process. The so-called fermentation, mostly refers to the process of decomposition of organic matter by organisms, fermentation is an earlier kind of human contact.
