在現(xiàn)代機械行業(yè)中，動力能源是必不可少的，空壓機在80年代之前，在我國的使用并不廣泛，這個現(xiàn)象一直延續(xù)到90年代，空壓機被廣泛的運用于各生產(chǎn)行業(yè)及機械設(shè)備上。近十年，噴油式螺桿空壓機使用尤為普遍。螺桿空壓機其供氣平穩(wěn)、維修率低、低噪音及省電環(huán)保等特點，填補了活塞空壓機的不足?，F(xiàn)階段在不斷引進(jìn)國外先進(jìn)技術(shù)的同時，我國也不斷研究新的技術(shù)。導(dǎo)致國內(nèi)生產(chǎn)螺桿空壓機的商家越來越多，用于滿足市場的需求，同時進(jìn)行出口，代表著我國的螺桿空壓機技術(shù)已邁進(jìn)一大步。 在噴油螺桿式空壓機中，油氣分離器是重要部件。為大家解析油氣分離器的使用。油氣分離器主要作用是減少空壓機的耗油量，確保壓縮空氣的含油量保持在3ppm內(nèi)?？諌簷C生產(chǎn)商不斷在技術(shù)上來減少空壓機的含油量，或者選擇較好的油氣分離器。在使用過程中出現(xiàn)效果不理想，含油量過大或壓差較大，甚至嚴(yán)重的燃燒爆炸。油氣分離器的應(yīng)用技術(shù)與空壓機出氣含油量及空壓機出氣流量和處理流量的配套產(chǎn)品有關(guān)系。 空壓機配套油氣分離器的情況下，油氣分離器必須選擇大于或等于空壓機的出氣流量，防止使用過程中吸入濾清器無法過濾的細(xì)小粉塵將油氣分離濾芯的細(xì)分離層堵塞，減少油氣分離器的處理流量，造成壓差過大。配套油氣分離器應(yīng)在空壓機出氣流量的百分之105以上選擇。 油的沉淀物，空氣中的污染物以及磨損的顆粒都能夠影響油氣分離器的使用壽命，不同的使用環(huán)境的最終壓差也不同。實際使用中，油氣分離器的最終壓差在0.8-1.0bar，真空泵為0.5bar。油氣分離器上的臟污在油量高是也會增多，可使用排污流量來衡量。排污量和空壓機的預(yù)分離結(jié)構(gòu)設(shè)計有關(guān)。排污量的最佳值在1g/m3左右。所以油氣分離器的使用壽命不能按時間衡量，只有用最終壓差來決定使用壽命。 在油氣分離器的使用過程中，新安裝的油氣分離器的正常壓差在0.17-0.3bar，超出.3bar是不正常的，此時需要檢查空壓機的最小壓力閥和其他配件是否損壞。
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.
