O/W型乳化液属高水基液,它是由3～5％的乳化油其余为水经充分混合搅拌而成。由于它具有抗燃节能等优点,近几年来,在冶金、煤炭、纺织、制塑等行业的液压设备中得到广泛应用。但因O/W型乳化液基体是水,与普通液压油相比其凝点较高(一般为-2～-3℃),特别在冬寒地区如不注意防冻问题,就有可能使油缸或管道冻结而影响生产,严重的会使管道冻裂造成重大事故。因此,为使液压系统安全可靠地运行,需适时地、因地制宜地采取防冻措施。
O / W emulsion is a high water-based liquid, it is from 3 to 5% of the remaining emulsion of water by mixing well. In recent years, it has been widely used in the hydraulic equipment of metallurgy, coal, textile, plastic and plastic industries because of its advantages of flame-retardant and energy-saving. However, because O / W emulsion base is water, its freezing point is higher than that of ordinary hydraulic oil (usually -2 ~ -3 ℃). Especially in the winter cold area, if you do not pay attention to antifreeze problem, it is possible to make the cylinder Or pipeline freezing and affect the production of serious pipeline cracking will cause a major accident. Therefore, in order to make the hydraulic system safe and reliable operation, it is necessary to take appropriate measures to prevent freezing.
