A大冶市陽新縣殼牌shell液壓油-壓縮機油經(jīng)銷國外空氣壓縮機油有代表性的規(guī)格標(biāo)準(zhǔn)有哪些? 答:國外空氣壓縮機油有代表性的規(guī)格標(biāo)準(zhǔn)有:德國DIN51506(我國GB12691參照此標(biāo)準(zhǔn)制定)，ISO/DP6521.3(我國 GB5904 參照此標(biāo)準(zhǔn)制定)。 12、氣體壓縮油是如何分類的? 答:ISO/DP6743/3將除空氣和冷凍劑以外的氣體壓縮機油按組成和特性分為五種，即DGA(礦油型)、DGB(特定礦油)、KGC(常用合成液)、DGB(非烴合成液)、DGE(常用合成液)，其中DGA氣體壓縮機油主要應(yīng)用在壓力小于100×105Pa的 N2、H2、NH3、CO2壓縮機及任何壓力下的He、Ar、SO2、H2S壓縮機。 13、如何選用空氣壓縮機油? 答:根據(jù)壓縮機油的設(shè)計類型、環(huán)境條件、操作負荷選擇空壓機油的類型，一般情況下，長期高溫環(huán)境(>30℃)下，選用L-DAB油，高速水冷或低壓、小壓縮比的壓縮機可選用低粘度壓縮機油。通常 空冷活塞式軸輸出功率<20KW，選用32、46、100號(環(huán)境溫度<-10℃可選32)DAA，DAB，DAC空壓機油What are the representative specifications and standards for foreign air compressor oil? Answer: The representative specifications and standards for foreign air compressor oil include German DIN51506 (referenced by China's GB12691), ISO/DP6521.3 (refere by China's GB5904). 12. How is gas compressor oil classified? Answer: ISO/DP6743/3ifies gas compressor oil other than air and refrigerant by composition and properties into five types, namely DGA (mineral oil type), DGB (specific mineral oil),GC (common synthetic liquid), DGB (non-hydrocarbon synthetic liquid), DGE (common synthetic liquid), among which DGA gas compressor oil is mainly used N2, H2, NH3, CO2 compressors with pressure less than 100×105 Pa and He, Ar, SO2, H2Sors at any pressure. 13.
