我采区一台4L— 20/8空压机,由于十字头和滑导部位多次烧损。1976年11月份我区维修人员,在技术人员和矿动力科的大力支持下,敢想敢于土法上马,自制设备对十字头和滑导部位进行了大胆的改造。在一台1.4千瓦的手提式电钻的基础上,自行设计了一台土镗床,将钻身安置在滑架内,用手动螺杆进行推进,再将其固定到机身缸体底座上,经校正后可进行对空压机滑导部位的镗削加工,镗去烧坏的表面,再经多次研磨提高了表面光洁度。对十字头的修复,先将十字头表面车去3毫米,再开出纵横各3个燕尾形槽,然后将其表面镀上5毫米厚的巴氏合金,按滑导尺寸进行车削,开出油沟,经进一步刮修使十字头和滑导之间隙合格。以上两项修复工艺均达到了设备的技术要求,经一年
I pick a 4L-20/8 air compressor area, due to the crosshead and slip guide parts burned several times. November 1976 maintenance staff in our area, with the strong support of the technical staff and the Department of Mines and Power, dared to dare to launch the native law, self-made equipment on the crosshead and slippery navigation parts bold transformation. On the basis of a 1.4 kilowatt handheld electric drill, a soil boring machine is designed by itself. The boring body is placed in a carriage and is propelled by a manual screw rod, and then fixed on the fuselage cylinder base, After the air compressor can be guided slip boring parts, boring to burn out the surface, and then repeated grinding to improve the surface finish. The crosshead repair, first cross the surface of the car to go 3 mm, and then out of vertical and horizontal each of the three dovetail groove, and then plated on its surface 5 mm thick Babbitt, according to the sliding guide size turning out Oil ditch, after further scraping to cross the crosshead and slip guide clearance. The above two repair processes have reached the technical requirements of the equipment, after a year
