The frequency of screw air compressor discharge (I. e. discharge of condensed water) should be determined according to the specific working conditions and the use of compressed air. Here are some serious considerations and recommendations:
1. working conditions
- ambient temperature and humidity:
- when the ambient temperature is high or the humidity is high, the water vapor content in the air increases, and the condensed water generated inside the air compressor will increase accordingly. Therefore, under these conditions, the frequency of water release should be increased. It is recommended to release water every 2-3 days, or even more frequently.
- Working pressure:
- screw air compressors that work under high pressure are more likely to produce condensed water due to the increase in gas temperature during compression. Therefore, the high pressure air compressor needs to discharge water more frequently than the air compressor at low pressure.
2. compressed air use
- if compressed air is used for clean air occasions with low requirements, the water discharge interval can be appropriately extended, such as once every half month or once every quarter.
- However, for occasions with high air quality requirements, such as food, medicine and other industries, the water discharge interval should be shortened to ensure the dryness of the compressed air.
3. specific operation suggestions
- periodic inspection:
- regularly check whether the drainage device of the air compressor is unblocked to ensure that the condensed water can be discharged in time.
- Timing of water release:
- the water discharge operation shall be carried out after the air compressor is shut down, the oil and gas separation tank has no pressure, is completely cooled, and the condensed water is fully precipitated. Before the boot is a good time to release water.
- Method of water release:
- manual drainage: Open the drain valve at the bottom of the air compressor and slowly drain the condensed water until a small amount of lubricating oil flows out.
- Automatic drainage: Some screw air compressors are equipped with automatic drainage devices, which can automatically discharge condensed water according to the set time interval.
4. Summary
in summary, the screw air compressor water frequency should be adjusted flexibly according to the specific working conditions and compressed air use. Under general working conditions, it is recommended to drain water at least once a day or week; when working in a high temperature and high humidity environment or under high pressure, the frequency of water discharge should be increased; for compressed air for specific purposes, the water discharge interval should be adjusted according to actual needs. At the same time, the drainage device should be checked regularly and ensure that the operation is correct.
Please note that the above suggestions are for reference only, and the specific water discharge frequency should be determined according to the actual operation of the air compressor and the manufacturer's instruction manual.
