In the chemical fiber industry’s production process, the air compressor is one of the core power equipment, which provides compressed air as a “second energy source”, involved in many core production links, directly affecting product quality (such as fiber uniformity, strength), production efficiency and energy costs.
Chemical fiber industry: compressed air
air jet loom is the largest air-consuming equipment in the textile industry. At the same time, airflow winding machine, elasticity machine also need compressed air; chemical fiber industry slice drying, transportation also need compressed air.
Ensure the quality of compressed air is not only related to the normal weft induction, should also ensure the stable operation of the air jet loom and the operating environment of the sanitary conditions. In general, as long as the need to meet the use of pressure, the textile process equipment can be used in line with the requirements of the air jet loom compressed air source. With reference to the requirements of various types of air-jet looms, the quality indicators of the compressed air required mainly include:Effective removal of as much liquid and gaseous water as possible, with a pressure dew point value of 8°C or less;clean air that is pure and oil-free;removal of dust and toner particles of 0.1μ or more;
The textile industry has a large production scale, if the compressed air delivery distance is long, it is necessary to configure the calculated pipeline and select the model with the corresponding exhaust pressure. Generally speaking, the air compressor power used for knitting, spinning and air jet looms is slightly different.
Chemical fiber industry: air compressor selection
1. Low-pressure screw compressor with after-treatment equipment
For the textile industry with long running time, large air consumption, low air pressure, cotton lint and other characteristics, combined with the requirements of a stable air source, clean and oil-free, elang has introduced the permanent magnet single-stage low-speed low-pressure series, permanent magnet two-stage low-pressure series, intelligent permanent magnet frequency conversion screw air compressor is the ideal choice. In the post-processing equipment, the configuration of precision filters, cold dryers for purification, so as to ensure the stability of production, minimize the harm to the textile equipment products.
2. Oil-free air compressor
oil-free screw compressor: using water lubrication or dry screw technology, exhaust oil content ≤ 0.01mg/m³, suitable for medium and high pressure (0.7-1.0MPa), large flow (50-500m³/min) scenarios (such as large spinning workshop); elang’s oil-free water lubrication compressor and dry screw air compressor can provide 100% pure compressed air.
Oil-free scroll compressor: simple structure, low noise (≤65dB), exhaust oil content ≤0.003mg/m³, suitable for small and medium flow rate (5-50m³/min) scenarios (e.g. laboratory spinning or small post-treatment line).
Compressor maintenance
| Maintenance Item | Maintenance Cycle | Maintenance Content |
|---|---|---|
| Air Filter | 1000-1500 hours | Replace filter element (prevent reduced air intake and increased energy consumption due to dust blockage) |
| Oil Filter (Lubricated Type) | 2000-3000 hours | Replace filter element (prevent impurities from entering the main unit and wearing the screw) |
| Adsorption Dryer | 4000-6000 hours | Replace adsorbent (such as activated alumina; failure will cause dew point to rise) |
| Precision Filter | 2000-3000 hours | Replace filter element (ensure oil and dust removal effect) |
| Main Unit Bearings | 20000-30000 hours | Check for wear and replace if necessary (prevent main unit seizure) |
