我厂工具处润滑站在对7231A型龙门刨床进行设备清洗换油时,首先将液压油箱的油放净,然后用亚麻布、净洗剂(X—1型金属净洗剂)进行清洗、干净后加入新油(N32~#液压油)。设备运转数日后,发现油面的导轨面上浮着一层废油,操作工即将设备停转。 经分析,查明其原因如下:设备换油按常规应该用煤油清洗,当时供应处油品库无煤油,润滑工就擅自决定用此净洗剂代替。在清洗过程中,虽对液压油箱进行了认真清洗,但对管道死角部位的清洗却不彻底。装入新油后,设备试车运转,残余的净洗剂与N32~#液压油起了化学反应,导致出现前述 I plant tooling station lubrication station 7231A gantry planer for equipment cleaning and oil change, the first hydraulic oil tank net release, and then with linen, detergent (X-1 metal detergent) to clean, clean After adding new oil (N32 ~ # hydraulic oil). After a few days of operation of the equipment, it was found that the guide surface of the oil surface floated with a layer of used oil, and the operator stopped the equipment immediately. After analysis, to identify the reasons are as follows: equipment, oil should be replaced by conventional kerosene, oil supply at the time there is no kerosene, Lubricant arbitrarily decided to use this detergent instead. In the cleaning process, although the hydraulic tank was carefully cleaned, but the pipe cleaning of the dead parts are not complete. After the installation of new oil, the equipment test run, the residual detergent and N32 ~ # hydraulic oil chemical reaction, resulting in the aforementioned
