大石头林业局第二林场自制的锯末纸浆机油滤芯,应用到内燃机上(包括汽车、拖拉机、绞盘机和电站等发动机),经两年来的生产试用证明,效果良好,吉林省林业局于74年7月通过生产试用鉴定,确定在全省林区推广使用。现将生产试用情况简介如下。一、特点1.润滑性能好锯末纸浆机油滤芯利用多孔深滤原理,增强了滤清杂质能力,可以保持机油质量基本不变。在拖拉机上应用超过200小时以上发现机油变黑,换上新滤芯,经18-24小时运转,机油的颜色可以改变过来,这就保证了机油质量经常处于良好状态,减少了机械磨损,延长了机械大修周期。2.节约油脂据目前实践结果,在拖拉机、电站和绞盘机上应 Self-made sawdust pulp filter at No.2 Forestry Center of Dashu Forestry Bureau applies to internal combustion engine (including engines such as automobile, tractor, winch and power station). After two years of trial production, it proved effective and Jilin Forestry Bureau in 74 years In July through the production trial appraisal, to determine the promotion of the use of forest in the province. Production trial is now briefings are as follows. First, the characteristics 1. Lubrication performance Good sawdust oil filter using porous deep filtration principle, enhanced filtration impurities ability to maintain the basic quality of oil. The application of more than 200 hours in the tractor oil was found black, put on a new filter, after 18-24 hours of operation, the color of the oil can be changed, which ensures that the quality of the oil is often in good condition, reducing mechanical wear and prolongation Mechanical overhaul cycle. 2. Save fat According to the current practice results, tractors, power plants and winch machine should be
