在现代机械行业中，动力能源是必不可少的，空压机在80年代之前，在我国的使用并不广泛，这个现象一直延续到90年代，空压机被广泛的运用于各生产行业及机械设备上。近十年，喷油式螺杆空压机使用尤为普遍。螺杆空压机其供气平稳、维修率低、低噪音及省电环保等特点，填补了活塞空压机的不足。现阶段在不断引进国外先进技术的同时，我国也不断研究新的技术。导致国内生产螺杆空压机的商家越来越多，用于满足市场的需求，同时进行出口，代表着我国的螺杆空压机技术已迈进一大步。   在喷油螺杆式空压机中，油气分离器是重要部件。为大家解析油气分离器的使用。油气分离器主要作用是减少空压机的耗油量，确保压缩空气的含油量保持在3ppm内。空压机生产商不断在技术上来减少空压机的含油量，或者选择较好的油气分离器。在使用过程中出现效果不理想，含油量过大或压差较大，甚至严重的燃烧爆炸。油气分离器的应用技术与空压机出气含油量及空压机出气流量和处理流量的配套产品有关系。   空压机配套油气分离器的情况下，油气分离器必须选择大于或等于空压机的出气流量，防止使用过程中吸入滤清器无法过滤的细小粉尘将油气分离滤芯的细分离层堵塞，减少油气分离器的处理流量，造成压差过大。配套油气分离器应在空压机出气流量的百分之105以上选择。   油的沉淀物，空气中的污染物以及磨损的颗粒都能够影响油气分离器的使用寿命，不同的使用环境的最终压差也不同。实际使用中，油气分离器的最终压差在0.8-1.0bar，真空泵为0.5bar。油气分离器上的脏污在油量高是也会增多，可使用排污流量来衡量。排污量和空压机的预分离结构设计有关。排污量的最佳值在1g/m3左右。所以油气分离器的使用寿命不能按时间衡量，只有用最终压差来决定使用寿命。   在油气分离器的使用过程中，新安装的油气分离器的正常压差在0.17-0.3bar，超出.3bar是不正常的，此时需要检查空压机的最小压力阀和其他配件是否损坏。
In the modern machinery industry, power energy is essential. Before the 1980s, air compressor was not widely used in China. This phenomenon continued until the 1990s. Air compressor was widely used in various production industries and mechanical equipment. In recent ten years, oil injection screw air compressor is widely used. Screw air compressor has the characteristics of stable gas supply, low maintenance rate, low noise, power saving and environmental protection, which fills the deficiencies of piston air compressor. At the present stage, while constantly introducing foreign advanced technologies, China is also constantly researching new technologies. As a result, there are more and more manufacturers producing screw air compressor in China, which are used to meet the market demand and export at the same time, which represents that the screw air compressor technology in China has stepped forward a big step. Oil gas separator is an important part in oil injection screw air compressor. For everyone to analyze the use of oil and gas separator. The main function of oil-gas separator is to reduce the oil consumption of air compressor and ensure that the oil content of compressed air is kept within 3ppm. Air compressor manufacturers continue to reduce the oil content of the air compressor technically, or choose a better oil-gas separator. In the process of using, the effect is not ideal, the oil content is too large or the pressure difference is large, even serious combustion explosion. The application technology of oil-gas separator is related to the oil content of air compressor outlet gas and the matching products of air compressor outlet gas flow and treatment flow. When the air compressor is equipped with an oil-gas separator, the oil-gas separator must select a flow rate greater than or equal to that of the air compressor, so as to prevent the fine dust that cannot be filtered by the filter in the process of use from blocking the subdivision separation layer of the oil-gas separation filter element, so as to reduce the processing flow of the oil-gas separator and cause excessive pressure difference. The matching oil-gas separator should be selected at more than 105% of the air compressor outlet flow. Oil sediment, air pollutants and wear particles can affect the service life of the oil-gas separator, and the final pressure difference is different in different environments. In practice, the final pressure difference of oil-gas separator is 0.8-1.0 bar, and that of vacuum pump is 0.5 bar. The dirt on the oil-gas separator will increase when the oil volume is high, which can be measured by the blowdown flow. The amount of blowdown is related to the pre separation structure design of air compressor. The optimal value of sewage discharge is about 1g / m3. Therefore, the service life of the oil-gas separator can not be measured by time, and the service life can only be determined by the final pressure difference. In the process of using the oil-gas separator, the normal pressure difference of the newly installed oil-gas separator is 0.17-0.3bar. It is abnormal to exceed. 3bar. At this time, it is necessary to check whether the minimum pressure valve and other accessories of the air compressor are damaged.
