近两年来,我们在设备润滑上作了点滴改革,现分述如下: (1)把7台3L-10/8型与4L-20/8型空压机,改为F-4无油润滑(即用F-4塑料活塞环代替金属活塞环,不加润滑油)。效果:节省一个注油器,减少了泄漏,每台机每月节约润滑油40公斤,同时提高了高压风的纯度,空压机运转正常。该项目获得1981年度市建材局的技术革新成果奖。 In the past two years, we made a bit of reform on the lubrication of the equipment and are as follows: (1) The 7 sets of 3L-10/8 and 4L-20/8 air compressors were replaced by F-4 oil-free (Ie F-4 plastic piston rings instead of metal piston rings, without lubricating oil). Effect: Save an oiler, reducing leakage, each machine saves 40 kg of lubricants each month, while improving the purity of high pressure air, air compressor is operating normally. The project won the 1981 Municipal Building Materials Bureau of technological innovation achievement award.
