Everyone is using air compressors, but also pay attention to maintenance.
The current inverter air compressor market presents high energy consumption and high pollution. Domestic high-conversion air compressor products have begun to tend to reduce energy consumption, low noise, high efficiency, high reliability, and structural integration. However, under the constraints of domestic and international economic constraints, China The product value expansion and main body upgrade of the high-pressure air compressor industry have not been effectively extended.
At this stage, although China's market has emerged a small number of subjects with more advanced technology, higher quality products and more innovative models, but under the impact of huge market demand and foreign advanced enterprises, it is difficult to pull this small part of the main body. China's high-pressure air compressor industry economic growth.
The vulnerable parts of the main part of the inverter air compressor mainly include: various gaskets, sealing rings, shaft oil seals, etc., especially the shaft oil seal, which is in the environment of high temperature, high pressure and high speed for a long time. shorten. The direct consequence of the damage is that the compressor leaks oil. If it is not found in time, it will cause the yin and yang rotor and bearing to burn out due to lack of lubrication.
The cost here refers to maintenance costs and electricity costs. Since the main engine of the inverter air compressor is not overhauled for a long time, the wear of the components is increased, and some worn impurities remain in the main cavity, which will shorten the life of the lubricating fluid. At the same time, due to impurities, the oil separator core and the oil filtration period The use time is greatly shortened, resulting in an increase in maintenance costs. In terms of power cost, as the friction increases and the compression efficiency decreases, the power cost will inevitably increase. In addition, the decrease in gas volume and the degradation of compressed air quality due to the compressor main unit may also cause an indirect increase in production costs.
The frequency conversion air compressor usually uses the PID closed-loop program control system. The installed inverter control system and the local pressure signal sensor can not achieve a good synchronization match, which will result in a series of slow and disorderly signal transmission during operation. The phenomenon occurs, increasing the equipment failure rate. Permanent magnet inverter air compressor manufacturers generally do not support the installation of external inverters.
