Matters needing attention when using variable frequency screw air compressor
The permanent magnet screw air compressor unit does not require special installation foundation. The low-speed fan and modern vibration isolation and noise reduction measures make the compressor operate with low noise, so it is convenient for users to place it on the production site. As long as the equipment is in place and the pipeline is connected Fast, it works right away. Screw air compressors are divided into single-screw air compressors and twin-screw air compressors. The twin-screw structure is more reasonable and stable, so it is more popular. Users should pay attention to the following four points when using screw air compressors:
- The rotational speed of the screw air compressor is a very important parameter for the screw air compressor. If the rotational speed is too high, the rotor load is too large, the rotational speed is too low, and the exhaust pressure is insufficient, so it is necessary to control the rotational speed within a reasonable range;
- The working temperature of the screw air compressor and the lubricating oil are greatly affected by the temperature. If the temperature is too high, the lubricating oil may deteriorate and fail to lubricate; if the temperature is too low, the lubricating oil may solidify. The discharge volume of the permanent magnet screw air compressor can be combined with the user’s gas consumption to avoid the loss of unloading power; in the intermittent gas consumption state, through the zero-load effect of soft start, the peak value of current and torque can be avoided, so that the unit can Can start and stop unlimited times. When choosing lubricating oil, it is necessary to choose lubricating oil with suitable viscosity and high lightning.
- The lubrication methods of screw air compressors are divided into oil and oil-free, but most factories still use oil-bearing screw air compressors, and the compressed air can also meet the production requirements of the factory. The air compressed by the oil-free screw air compressor does not contain air compressor oil, which is in line with industries such as medicine, food, and instruments that have high quality requirements for compressed air.
- If the air humidity is too high or there are many impurities in the air, the working efficiency of the air compressor will be affected by the environment, and the efficiency of the air compressor to compress the air will be reduced. The discharge volume of the permanent magnet screw air compressor can be combined with the user’s gas consumption to avoid the loss of unloading power; in the state of intermittent gas consumption, the zero-load effect of soft start is used to avoid the peak value of current and torque, so that the unit can operate. stop. Therefore, the air compressor should be placed in an environment with ventilation, suitable temperature and good air quality.
