我公司在刚引进国外设备时,设备用油基本上采用国产油代用。如两台德国产液压剪板机采用国产46~#抗磨液压油代用,两台瑞土产三点式折弯机采用国产68~#抗磨液压油代用,两台日本产程序冲孔机采用国产8~#液力传动油代用。经两年多的运行证明,8~#液力传动油完全能符合机床的工作要求,但46~#及68~#抗磨液压油在盛夏无法使机床正常工作,其主要原因为粘—温特性较差(一般粘度指数为95)。因此本文着重从粘温性及粘度指数来考虑液压油与进口设备的关系。
My company just introduced foreign equipment, equipment, oil basically use domestic oil substitute. For example, two German hydraulic shearing machines are made of 46 ~ # anti-wear hydraulic oil made in China. Two Swiss-made three-point bending machines are made of 68 ~ # anti-wear hydraulic oil. Two Japanese-made punching machines adopt domestic 8 ~ # Hydraulic transmission oil alternative. After more than two years of operation proved that 8 ~ # hydraulic transmission oil can fully meet the requirements of machine tools, but 46 ~ # and 68 ~ # anti-wear hydraulic oil in the summer can not make the machine work, the main reason is sticky - temperature Poor characteristics (general viscosity index of 95). Therefore, this article focuses on viscosity and viscosity index to consider the relationship between hydraulic oil and imported equipment.
