4115柴油机的油底壳衬垫、挺杆室侧盖衬垫、气门罩框盖衬垫都是用压制合成软木(Q/Q207-64)制成的.这种软木垫的特点是弹性好,压紧状态下密封油、气的效果较好;但较脆弱不耐弯折,容易拉断,使用中特别在拆卸时很容易损坏,使用一定时间会压实失去弹性,密封效果相应变差. 一般安装中是将油底壳衬垫和挺杆室侧盖衬垫粘在壳体和侧盖的密封边缘上,在更换垫片时应先将壳体和盖板上的旧垫去除,使结合面清洁平整.然后在壳体和侧盖的结合面上涂抹床垫胶(吸纳胶),再把软木垫粘上.油底壳软木垫共由四段组成,为使各段榫头搭接好并对正所有螺栓孔眼.软木垫经水中浸泡后
4115 Diesel engine oil sump liner, tappet chamber side cover gasket, valve cover gasket are made of pressed synthetic cork (Q / Q207-64) .The cork mat is characterized by good elasticity, Compressed state seal oil, gas better; but more vulnerable intolerance bending, easy to pull off, especially when used in the demolition is very easy to damage, the use of a certain time will be compacted lose elasticity, the corresponding sealing effect worse. In general installation, the oil sump gasket and the tappet chamber side cover gasket are stuck on the sealing edge of the shell and the side cover. When replacing the gasket, the old cushion on the shell and the cover plate should be removed first Clean the surface with a combination of surface and then the shell and the side cover with a combination of mattress glue (absorbent glue), and then stick the cork mat Oil pan cork mat consists of four sections, in order to make the lap joints Good and right for all bolt holes.
