S195柴油机高压油管常出现断裂,经我们检查分析,原因如下: (1)高压油管是直径为6毫米的细长管,与喷油泵总成及喷油器总成联接,为避免悬空和振动,厂家采取高压油管夹紧固的办法,但一些机手忽视了紧固夹的作用,往往在修理、保养中漏装或拿掉,造成高压油管悬空,当出现严重震动时,高压油管两端联接的颈部易被震裂,这是主要原因。
S195 diesel engine high-pressure tubing often rupture, after our inspection and analysis, the reasons are as follows: (1) high-pressure tubing is a 6 mm diameter slender tube, and injection pump assembly and fuel injector assembly connection, in order to avoid dangling and vibration, The manufacturer adopts the method of fastening the high-pressure tubing clamps. However, some of the machines neglect the function of the fastening clamps, often missing or removing the high-pressure tubing during maintenance and repairs. When there is a serious vibration, the high-pressure tubing ends are connected The neck is easily shattered, which is the main reason.
